audiences are the developers and engineers responsible for the integration of the module in another product. safety precautions to prevent damage to the sx-550 modules electronic circuit components, follow established esd practices and procedures for handling static-sensitive devices. all esd-sensitive components must be stored and shipped in esd-conductive bags or bubble-wrap and labeled as such using the standardized esd adhesive warning label. ethernet electrical wiring must be at least 6 feet from bare power wiring or lightning rods and associated wires, and at least 6 inches from other types of wire (antenna wires, doorbell wires, wires from transformers to neon signs), steam or hot water pipes, and heating devices. protectors and grounding wire placed by the service provider must not be connected to, removed, or modified by the customer. emissions dis claimer final emission certification per fcc, ce and other agency requirements are the responsibility of the oem using any printed circuit assemblies or other items used in this developers kit in their saleable packaged product. part number 40183-101 silex sx-550 developer's guide page 1 part number 40183-101 silex sx-550 developer's guide page 2 chapter 1: introduction the sx-550 embedded intelligent module provides a complete solution for integrating wireless or wired networking technology into virtually any oem product that has an rs-232 or uart serial port. it can also be used as an ethernet to 802.11 bridge to enable wireless capabilities on devices that have an ethernet interface. it is available in two models: sx-550-0700 ethernet model. the sx-550 ethernet model consists of a printed circuit board (processor card) that measures 44.60 mm by 59.70 mm. it includes an embedded processor, auto-sensing 10base-t/100base-tx ethernet mac/phy, two uart serial ports (one port is dedicated for use with a console terminal), intelligent power control, and an embedded operating system with a full networking stack and drivers. sx-550-2701 wlan model. this wireless model uses the same processor card as the ethernet model, but also adds a second printed circuit board (radio card) that contains an 802.11a/b/g wireless lan radio based on atheross ar5413 chipset. this second board measures 36.0 by 59.70 mm; the two boards plug together via a 20-pin connector. note that the ethernet interface and the wireless radio cannot be used concurrently except when the ethernet-to-802.11 bridge mode feature is enabled. the sx-550-2701 includes fcc modular approval, which can eliminate the need to test for compliance with fcc part 15 subparts c and e and rss-210 intentional radiation standards. please refer to appendix d for specific information about fcc modular approval. important: the sx-550-2701 modular approval requires use of an antenna and antenna cable with the same characteristics as those used for the silex testing. silex can only support testing of other antenna configurations in the end user product for the us and canada regulatory domains. SX-550-1701 wlan model. this wireless model uses the same processor card as the ethernet model, but adds a second printed circuit board (radio card) that contains an 802.11a/b/g wireless lan radio based on conexants prism worldradio chipset. this second board also measures 44.60 by 59.70 mm; the two boards plug together via a 20- pin connector. note that the ethernet interface and the wireless radio cannot be used concurrently except when the ethernet-to-802.11 bridge mode feature is enabled. part number 40183-101 silex sx-550 developer's guide page 3 important: the SX-550-1701 model does not include fcc modular approval, so it is the responsibility of the oem to test for compliance with fcc part 15 subparts c and e and rss-210 intentional radiation standards. figure 1 SX-550-1701 (left) and sx-550-2701 (right) the SX-550-1701 and sx-550-2701 are virtually identical in form and functional identical, with a few minor differences. the one major difference is the sx-550-2701 includes fcc modular approval (see appendix d). other differences include: international roaming (802.11d) is a standard non-configurable feature of the sx-550- 2701, so there are no corresponding configuration items. programmable rts threshold is supported on the SX-550-1701 and not on the sx-550- 2701 user defined scan mask is supported on the sx-550-2701 and not on the SX-550-1701 user

sx-550 developer's guide page 17 part number 40183-101 silex sx-550 developer's guide page 18 chapter 3 configuring the sx-550 this chapter describes the methods for configuring the basic settings of the sx-550, including the ip address, serial port settings, and wireless security. the sx-550 also has an extensive range of advanced configuration capabilities that are described in chapter 6, appendix a, and appendix b. the sx-550 configuration should be done by a network administrator or another person with technical knowledge of tcp/ip networking and serial communications. basic configuration requirements in order to use the sx-550, the following basic parameters must be configured: tcp/ip settings: ip address subnet mask router address note: the tcp/ip settings can be automatically configured using dhcp. wireless configuration settings: ssid mode (infrastructure or ad hoc) channel (required only if using ad hoc mode) security settings: wireless encryption mode (wpa2, wpa, wpa2-wpa, wep) wireless encryption settings wireless authentication mode (wpa-psk, open system, shared key, ttls, tls, leap, peap, eap-fast) wired authentication mode (ttls, peap, eap-fast) authentication settings part number 40183-101 silex sx-550 developer's guide page 19 i mportant: this chapter assumes that you are either using the sx-550-6900 evaluation daughtercard or that you have made the appropriate connections to the sx-550 module oem header. refer to chapter 2 and chapter 5 for information on connecting to the sx-550 hardware. note: there are numerous possible encryption and authentication settings, and every network can have different settings. please refer to appendix a for a detailed summary of these settings. serial port settings (must match the settings of the attached serial device): baud rate (speed) parity character size flow control in addition to the above parameters, the sx-550 allows you to configure numerous other capabilities. these other capabilities provide you with the unparalleled flexibility to use the sx-550 on virtually any 802.11a/b/g or ethernet network with virtually any rs-232 serial device. configuration methods there are three ways to configure the sx-550: extendview. extendview is a simple graphical user interface configuration program for windows. in addition to setting up the initial sx-550 configuration, extendview also has the advantage of allowing you to perform bulk configuration of multiple sx-550s simultaneously. internal web pages (http). you can use any standard web browser to access the sx-550 internal web pages. these web pages provide an easy-to-use graphical interface for configuring the sx-550. in order to use the internal web pages for the first time, you must assign the sx-550 ip address using some other method (for example, dhcp or arp/ping). this initial ip address assignment need only be done one time. internal command console. the internal command console provides a sophisticated command line interface for advanced users to configure the sx-550. it can be accessed by connecting a serial cable to serial port 2. once the ip address has been assigned, the internal command console can also be accessed via telnet, or via extendview and the internal web pages. although it is possible to configure the sx-550 wlan model with a completely wireless setup, it is much simpler to perform the process using a wired ethernet connection. this is primarily because the wireless security on most wireless networks prevents the addition of a new wireless device unless all security parameters are first entered into that device. as a result, you must set up a temporary dedicated ad hoc wireless network in order to configure the sx-550 in a completely wireless environment. configuring the sx-550 using each of the above methods is described in the following sections of this chapter. part number 40183-101 silex sx-550 developer's guide page 20 using the extendview utility to configure the sx-550 (ethernet connection) the extendview utilty is the easiest way to initially configure the sx-550 from a windows pc because it allows you to directly set the ip address into an unconfigured sx-550, and it allows you to view the ip addresses of all of the sx-550s on your network. it has limited capabilities for configuring 802.1x authentication, but it can be used in conjunction with either the internal web pages or the internal command console for complete configuration capabilities. extendview is a component of the cd-rom that is included with the evaluation daughtercard, or it can be downloaded from the silex website. to install extendview, simply follow the on-screen installation instructions. the sx-550 configuration procedure is as follows (please note that the screens may be slightly different than shown, depending on the sx-550 model and the firmware and software revision levels). 1. start the extendview utility by clicking on start , programs, silex technology, extendview , and then extendview . 2. when the welcome screen appears, click on next , choose any name for your view name , select automatically create a view with default settings (or configure the view to your preferences), and then click finish . part number 40183-101 silex sx-550 developer's guide page 21 note: skip this section if you do not have a windows pc or if you do not have an ethernet connection to the sx-550. 3. right-click on the sx-550 that you want to configure from the displayed list, and then left- click on configuration . the default sx-550 name is sds xxxxxx (where xxxxxx is the last six digits of the mac address from the label that is affixed to the sx-550). 4. if you do not have a dhcp server, you will be asked to manually enter an ip address (if you are not sure what ip address to enter, ask your network administrator). click ok when you are finished. 5. the server configuration window will appear. check the ip address setting to make sure it is correct. if necessary, change the subnet mask and gateway. if you have a wins server, enter its address or click use dhcp to locate wins server. if desired, you can configure advanced tcp/ip settings by clicking the advanced tcp/ip button (refer to chapter 6 for information). this advanced configuration can be done at a later time, however. part number 40183-101 silex sx-550 developer's guide page 22 note : if you are using dhcp on your network, the sx-550 should have acquired valid ip settings at this point and no further configuration is necessary. however, for some installations, a static ip address is preferred. if your dhcp server does not allow the sx-550 to keep its assigned ip address permanently, then you must manually assign an ip address. in this case, use a static ip address outside the range reserved for dhcp (see your dhcp server documentation for details). to assign a static ip address, select set permanent as the ip address resolution , and assign a valid static ip address for your network. click on ok to save the new settings. 6. click the wireless tab to configure the 802.11a/b/g wireless settings (for wireless models only; skip to the next section if you have a wired model). to operate on an 802.11a/b/g network, the sx-550 configuration must be configured with the wireless configuration and security parameters necessary for the sx-550 to communicate over your wireless network (check with your network administrator if you do not know these parameters). select either infrastructure (if you are using an access point) or ad hoc (point-to-point) as the wireless mode enter the ssid for your network if you are using ad hoc, select the rf channel (not required for infrastructure) the other parameters on this tab do not normally need to be changed (refer to chapter 6 for information on advanced configuration). now click the configure wireless security button to configure the wireless security parameters. 7. if you are using wpa2-psk, select wpa2 as the encryption mode and select psk as the authentication type. if you are using wpa- psk, select wpa as the encryption mode and select psk as the authentication type. for both wpa2-psk and wpa-psk you must enter the pre-shared key for your network and select whether you want a group key. note that it is not necessary to enter a user id or password. if you are using wep, select 128-bit or 64-bit as the encryption mode and open systems or shared key as the authentication type. enter the wep keys in hexadecimal format, and select the transmit key (key selection). extendview does not fully support configuration of the 802.1x eap types, so silex recommends using the internal web pages or internal command console for 802.1x configuration as described later in this chapter. click ok to return to the server configuration window, and then click the i/o port tab to configure serial port 1. part number 40183-101 silex sx-550 developer's guide page 23 8. you do not need to change any of the settings in this window. click the serial settings button to configure the serial port. 9. configure the serial port settings so that they match the settings on your device. for example, if your device is set for 9600bps, odd parity, and xon/xoff flow control, you must change the settings on the sx-550 to these settings click ok when you are finished to return to the server configuration window and then click ok again. 10. click ok to save your changes and reset the sx-550. you can now use the sx-550 on your network. you may skip the remaining sections of this chapter, although this information is useful for future reference. first-time ip address configuration if you are configuring the sx-550 from a non-windows computer or if you cannot use an ethernet connection, you must first configure the sx-550 ip address. note that it is only necessary to perform this part number 40183-101 silex sx-550 developer's guide page 24 note: skip this section if you have already configured the sx-550 ip address with extendview task one time -- once the address has been configured, the sx-550 can be accessed from any computer on the network that has the appropriate privileges. the steps are as follows: 1. if your network has a dhcp server and you can use an ethernet connection to the sx-550: a. make sure your pc is connected and has access to your network. b. connect an ethernet cable from your network hub to the sx-550 (if you have a wireless sx-550 and do not have hardwired capabilities, then you must go to step 4 below for setup instructions). c. power on the sx-550. d. the administration program on most dhcp servers logs the ip address and mac address of each dhcp client. the mac address of the sx-550 can be found on the label affixed to the unit. if your dhcp server has logged this information, write down the ip address of the sx-550 for future reference. you are now ready to configure the sx- 550 (skip the remainder of this section). e. if your dhcp server does not provide client information or if you do not have access to the dhcp server, then you can get the ip address by connecting a serial device such as a printer, a windows pc running hyperterminal, or another serial device capable of printing ascii characters to serial port 1 on the sx-550 (the cable supplied with the sx- 550-6900 evaluation daughtercard will work with many such devices). if you are not using the evaluation daughtercard, then you must provide the appropriate cable to connect pins 9, 11, and one of the ground pins on the oem header to the terminal (transmit data on the sx-550 must connect to receive data on the terminal, and vice- versa). your serial device must be set at 115.2kbps, 8-bit character size, and no parity. f. with the serial device and sx-550 switched on and ready, press the test button on the sx-550-6900 evaluation daughtercard, or short gpio7 on the oem header to ground ( 4.7 k-ohm pull-up resistor connected to +3.3 vdc). this will cause the sx-550 configuration data to be sent to the connected serial device. the serial device should display or print the current ip address assigned to the sx-550 by your network dhcp service. write down this address for future reference. you are now ready to configure the sx-550 (skip the remainder of this section). 2. if you can connect the sx-550 via ethernet but do not have a dhcp server, then you must use the following procedure for the first-time ip configuration of the sx-550. a. make sure your pc is connected and has access to your network b. connect an ethernet cable from your network hub to the sx-550. the sx-550 must be on the same network segment as the pc (that is, there can be no router between the sx- 550 and the pc). c. from the windows command prompt (ms-dos prompt), the mac os x terminal utility, or the unix/linux command line, enter the command arp Cs ipaddress macaddress ping ipaddress where ipaddress is the desired ip address of the sx-550 and macaddress is the mac address of the sx-550 (found on the label affixed to the sx-550). for example: arp Cs 192.168.5.53 00:40:17:00:00:01 ping 192.168.5.53 note that windows systems use the format xx-xx-xx-xx-xx-x x for the mac part number 40183-101 silex sx-550 developer's guide page 25 address (for example, 00-0017-00-00-01). you will see a reply from the sx-550 with the number of bytes and other information if the address was successfully set. if you get an error message or no response, then the ip address was not set. if this is the case, the sx-550 may not be at its default configuration. to reset the sx-550 to its default settings, hold down the test button on the evaluation daughtercard for more than five seconds. if you are not using the evaluation board, short gpio7 on the oem header to ground (4.7 k-ohm pull-up resistor connected to +3.3vdc) for more than five seconds. d. you are now ready to configure the sx-550 (skip the remainder of this section). 3. if you can connect to an ascii terminal (such as a pc running the hyperterminal accessory program) to serial port 2 on the sx-550, you can configure an ip address using the internal command console. to do this, set the terminal to 115.2kbps, 8-bit characters, no parity, and no flow control. use the appropriate cable to connect the terminal to serial port 2 (if you are using the evaluation daughtercard, the included serial cable will work for many devices). press using a web browser to configure the sx-550 after you have entered an ip address into the sx-550, you can use any standard web browser to access the internal web pages for configuring the sx-550. simply specify the ip address of the sx-550 in your browser and then follow the steps below: 1. when you have connected to the sx-550, you will get the server info page. click login on the left side of the screen. 2. enter the password access and press submit . 3. you will return to the server info page, but new options will be listed on the left side of the screen. click on tcp/ip . part number 40183-101 silex sx-550 developer's guide page 27 i mportant : you must click the submit button when you have finished configuring an internal web page. if you do not do this, your changes will not be saved. you may skip this section if you have completely configured the sx-550 using extendview. however, if you have advanced configuration requirements, such as 802.1x eap configuration, then you may need to use the internal web pages as described in this section because extendview does not support these capabilities. if you used dhcp, verify that the ip address is correctly set. if you used the default 192.0.0.192 ip address, you must change it to a new valid ip address. if necessary, change the subnet mask and gateway. it is generally not necessary to change the other parameters on this page (refer to chapter 6 for advanced configuration information. note that on-line help information is available on every configuration page. click the submit button at the bottom of the window (you may need to scroll) to save your changes. 4. click wireless on the left side of the screen to configure the 802.11a/b/g wireless settings (for wlan models only; skip to the next section if you have an ethernet model). to operate on an 802.11a/b/g network, the sx- 550 configuration must be configured with the wireless configuration and security parameters required to allow the sx-550 to communicate over your wireless network (check with your network administrator if you do not know these parameters). select either infrastructure (if you are using an access point) or ad hoc (point-to-point) as the wireless mode enter the ssid for your network if you are using ad hoc, select the rf channel (not required for infrastructure) the other parameters on this page do not normally need to be changed (refer to chapter 6 for information on advanced configuration). click the submit button at the bottom of the window (you may need to scroll) to save your changes. now click configure network security to part number 40183-101 silex sx-550 developer's guide page 28 note : if you are using dhcp on your network, the sx- 550 should have acquired valid ip settings at this point and no further configuration is necessary. however, for some installations, a static ip address is preferred. if your dhcp server does not allow the sx-550 to keep its assigned ip address permanently, then you must manually assign an ip address. in this case, use a static ip address outside the range reserved for dhcp (see your dhcp server documentation for details). to assign a static ip address, select set permanent as the ip address resolution , and assign a valid static ip address for your network. click on ok to save the new settings. configure the wireless security parameters. 5. select the appropriate wireless encryption mode and enter the required settings (check with your network administrator for the proper settings if you do not know them). appendix a lists the possible encryption settings. click the submit button at the bottom of the window (you may need to scroll) to save your changes. now click i/o port on the left side of the screen to configure the serial port. 6. configure the serial port settings so that they match the settings on your device. for example, if your device is set for 9600bps, odd parity, and xon/xoff flow control, you must change the settings on the sx-550 to these settings. click the submit button at the bottom of the window (you may need to scroll) to save your changes. when you have finished with all your configuration changes, you must restart the sx-550 for these changes to take effect . you can skip the remainder of this chapter. using the internal command console to configure the sx-550 the internal command console is a command line oriented method for configuring the sx-550. it provides more comprehensive capabilities than either extendview or the internal web pages, but is not as easy to use. advanced users may prefer to use this method because it is concise, fast, and powerful. to use the internal command console: 1. the simplest way to access the internal command console is via a terminal (for example, a windows pc running the hyperterminal accessory program) connected to serial port 2. if you are using the sx-550-6900 evaluation daughtercard, the included serial cable can be used for this purpose. if you are not using the evaluation daughtercard, then you must provide the appropriate cable to connect pins 21, 22, and one of the ground pins on the oem header to the terminal (transmit data on the sx-550 must connect to receive data on the terminal, and vice- versa). the terminal must be set for 115.2kbps, 8-bit characters, no parity, and no flow control. part number 40183-101 silex sx-550 developer's guide page 29 you may skip this section if you have completely configured the sx-550 using extendview or the sx-550 internal web pages. however, if you are using the bridge mode, you must use the internal command console (see chapter 4 for information on configuring bridge mode. 2. when the sx-550 is powered on, you will see some information about the firmware versions and copyright notices displayed on the terminal. when you see the local> prompt, you can enter commands. the sx-550 is set by default to use dhcp to obtain the ip address automatically. if you want to set the ip address manually, enter the following commands: set ip address aa.bb.cc.dd set ip subnet aa.bb.cc.dd set ip router aa.bb.cc.dd where aa.bb.cc.dd is the ip address of the sx-550. you can use the command show ip to verify the ip address settings. 3. enter the basic wireless settings as follows: set nw ssid set port s1 flow part number 40183-101 silex sx-550 developer's guide page 32 chapter 4 using the sx-550 with your application the sx-550 includes a number of capabilities that enable it to be used in a wide range of applications. these capabilities include: 1. user interface customization 2. power configuration 3. serial port emulator (spe) software 4. raw tcp connection 5. rfc2217 6. ecable mode 7. print server mode 8. ftp 9. console mode switching 10. at commands 11. snmp traps and email alerts 12. ethernet-to-wireless bridge mode these methods are described in the following sections. part number 40183-101 silex sx-550 developer's guide page 33 customizing the sx-550 user interface the sx-550 user interface can be customized to include your companys name or other information. for example, instead of displaying silex sx-550 on the internal web pages and the internal command console interface, the sx-550 could display company xyz . in addition, the 3-character oem code used in the sx-550 server name and service names can be changed from the default code sds to a user- defined code. for example, by changing the oem code to xyz, the default server name sds000345 would become xyz000345 . to make these changes, enter the following commands using the internal command console: set oem code where code is the desired 3-character oem code set default [note that this resets the entire sx-550 configuration back to the factory defaults] set server desc description where description is any string up to 32 characters in length [note that spaces are ok in the description and no quotation marks are necessary] init [restarts the sx-550 when the user exits the console] exit [exits the console] power configuration the sx-550 can be set to go into power save mode by using the console command set power n where n is 0 for high (power is always on), 1 for medium, and 2 for low (lowest power consumption). the show power command shows the current power configuration. serial port emulator the serial port emulator (spe) software emulates a standard windows com port. that is, it creates a virtual com port that functions exactly like the windows com1 and com2 serial ports, except that the i/ o actually goes out over the ethernet or wlan to the sx-550 and to the serial device that is connected to the sx-550. as a result, any application program that uses a standard windows com port can also use the serial port emulator. the spe is therefore especially useful if you have existing programs that use windows com ports. the spe software is a component on the cd-rom that is included with the sx-550-6900 evaluation daughtercard, or it can be downloaded from the silex website. to install it, double click on the installer icon and follow the installation instructions. when the installation is complete, you can run the spe software by clicking start -> programs -> silex technology -> serial port emulator -> serial port emulator. part number 40183-101 silex sx-550 developer's guide page 34 important: this user interface customization must be done before making any other configuration changes, because the set oem command requires that the sx-550 be reset to the factory default configuration. after the serial port emulator software has started, you will see a list of all the configured sx-550s on the network. right click on the name of the sx-550 that you want the virtual com port to connect to (the default name is sds xxxxxx , where xxxxxx is the last six digits of the sx-550 mac address), and then click virtual port . you will be asked to select the name of the virtual com port (for example, com3). the advanced button allows you to select rfc 2217 support (see rfc 2217 section below) or strict baud rate emulation (the spe normally transfers data at the maximum network speed for best performance; the strict baud rate feature forces the data rate to run at the actual baud rate without buffering for compatibility with older application programs that have strict timing requirements). click ok after you have selected the name, and you now ready to use the virtual com port. using virtual com port is identical to using a normal com port. for example, if you configure a virtual com port called com3, this port will show up as one of the available serial ports when you use the windows hyperterminal accessory program. raw tcp connection you can communicate directly from your application program to the sx-550 using a raw tcp connection. this is done by opening a tcp port on the sx-550 and then sending and receiving data to this port via a socket or equivalent api. this method is more efficient than using the serial port emulator, and does not require any additional software to be installed on your computer. if you are using a raw tcp connection, the default tcp port number is either 9100 or 3001 for serial port 1 or 9101 or 3002 for serial port 2 (you can use any or all of these port numbers) for normal connections. if you want to be able to access your devices modem control signals from your computer system, then the tcp port number is 9200 for serial port 1 or 9201 for serial port 2 (this enables rfc 2217 support). you can change the port number, if desired, by modifying one of the sx-550 services. to change the tcp port number: 1. connect to the sx-550 with a web browser (see chapter 3 for instructions on doing this); 2. after you have logged in, click i/o services on the left side of the page. 3. click on the service name that you want to change (any one of the services is ok, provided that you are not using the existing tcp port number of that service for a different application). 4. change the raw tcp port to the desired number (must be greater than 1023). 5. click submit to save your change. part number 40183-101 silex sx-550 developer's guide page 35 you can test this connection by using the telnet utility from the windows command prompt (ms-dos prompt), mac os x terminal utility, or unix/linux command line as follows: telnet ipaddress portnumber where i paddress is the ip address of the sx-550 and portnumber is the sx-550 tcp port number. for example: telnet 192.168.5.53 9100 in this example, if you have a serial printer or other device capable of displaying ascii characters connected to the sx-550 serial port 1, then every character you type should be printed on that serial device (buffered serial devices may need you to type a control character such as a formfeed (control- l) before the characters are printed). rfc 2217 support rfc 2217 allows you to connect from a host computer over the wireless or ethernet network to a serial device attached to the serial port of the sx-550, even if the baud rate of that device does not match the baud rate of the host computers software. for example, if the host computer software was set to 57.6kbs and the sx-550 serial port was set to 19.2kbps, the rfc 2217 support would take care of the mismatch. rfc 2217 also allows you to access your devices modem control signals over the network. it is especially useful for migrating applications that use modem controls from a direct serial connection to a serial device server network connection (rfc 2217 modem signal support is supported in sx-550 firmware versions 2.04 and higher). you can utilize rfc 2217 from the silex serial port emulator software (see above), or by connecting to tcp port 9200 from your application program. the rfc 2217 features supported by the sx-550 include: set and query baud rate set and query character size set and query parity set and query stop bits set (and query) outbound flow control setting (separate input & output flow control not supported) set outbound break state ** query inbound break state ** set and query dtr state set and query rts state (set only if not hw flow control) dcd, dsr & ri line monitoring ** ** requires 2.04 or later firmware *** only the break bit is tested to generate a notification, not the various transmit/receive status registers (tx empty, etc). ecable mode normally, it is up the computer to initiate a connection to the sx-550. for some applications, it is desirable for the sx-550 to initiate the connection to the computer. the sx-550 supports this capability through its ecable feature. part number 40183-101 silex sx-550 developer's guide page 36 to set e-cable mode, use a web browser to access the sx-550 internal web pages (see chapter 3 for instructions on using the internal web pages). after you have logged in, click i/o port on the left side of the screen. you can now enable ecable mode and set the required parameters. 1. enable ecable mode by clicking the radio button. 2. enter the address (destination address) of the computer or other device that will be communicating with the sx-550) 3. enter the tcp port number (destination port) used by the destination device for communicating with the sx-550 (must be greater 1023). 4. if desired, change the ecable connection attempt time. this specifies the time interval between connection attempts. for example, by default the sx-550 will try once every 30 seconds to make a connection to the destination device; if it fails to make this connection, it will wait 30 seconds before attempting again. changing this interval will reduce or increase the amount of network traffic. 5. it is also possible to use udp instead of tcp for communicating to and from the sx-550. if you wish to use udp, then: a. select udp as ecable i/o mode. b. enter the udp port number (destination port) used by the destination device to communicate with the sx-550. this number must be a valid port on the destination device (check the documentation for that device to determine the valid port numbers). c. enter the udp port number (local port) used by the sx-550 to communicate with the destination device. this number must be greater than 1023, but is otherwise arbitrary. part number 40183-101 silex sx-550 developer's guide page 37 note: ecable mode cannot be used in conjunction with the serial port emulator software. print server mode you can use the sx-550 as a standard tcp/ip print server, which is very useful if you are connecting the sx-550 to a serial printer. the sx-550 supports the following standards: lpr/lpd . this is one of the most popular ways to print on a tcp/ip network. check your computers documentation to determine how to set up an lpr print queue. usually this simply involves specifying the ip address of the sx-550 as the printers address or host name. some implementations require a queue name; this name is the name of any of the sx-550 services. to see the names of the sx-550 services, connect to the sx-550 with a web browser (see chapter 3 for instructions on doing this); after you have logged in, click i/o services on the left side of the page. port 9100 . this method is used to set up a windows standard tcp/ip port or for compatibility with software that supports the hp jetdirect print server (for example, hp web jetadmin). to use this capability on windows with the add printer wizard , specify that you want to use a local printer attached to this computer (not a network printer), and then select create a new port , specifying standard tcp/ip por t as the type of port. it is also possible to change the tcp port number from the default 9100 for compatibility with other printer manufacturers software. to do this, refer to the instructions in the raw tcp connection section of this chapter. ftp the sx-550 supports ftp binary or ascii communications. this can be used, for example, to send the contents of a file from a pc to a device connected to the sx-550 using the ftp protocol. to use ftp, simply enter the standard ftp command from your pc with the ip address of the sx-550 (for example, ftp 192.168.5.50 ). when the connection is made, enter any username and password. you can then use the standard ftp put command to send the file from the pc to the device connected to serial port 1 on the sx-550. console mode switching the sx-550 allows you to dynamically switch the operation of serial port 1 from normal mode to console mode. this allows your device to control the operation of the sx-550 by sending console commands (see chapter 6 and appendix b for a description of the console commands). to switch the serial port to console mode, you must first define a console string. when the sx-550 receives this string on the serial port, it will automatically switch the port to console mode. to define the console string, use a web browser to access the sx-550 internal web pages. after you log in, click i/o port, and then select the desired port (s1 for serial port 1). when you get the i/o port settings page, enter any desired character string (for example, xyz) as the console mode string . click submit to save your string, and then restart the sx-550 to make the change take effect. alternatively, you can define the console mode string using the console command as shown in the following example: set port s1 constr xyz part number 40183-101 silex sx-550 developer's guide page 38 once you are connected in console mode, you can send any of the console commands listed in chapter 6. be sure to terminate each console command with a carriage return (ascii 13) or linefeed (ascii 10) character. when you are finished using the console, you can return to the normal port operation by sending the command exit followed by a return or linefeed character. at commands the sx-550 allows you to control the serial port using standard at modem commands. this allows you, for instance, to initiate connections and to switch between console mode and data mode by sending the appropriate commands. these capabilities are similar to the console mode switching described in the previous section, but has the following advantages; your device can initiate a network connection operation is compatible with software that uses the at command set the drawback, however, is that there is a slight delay when switching from data mode to at command mode. to use the at commands, you must first enable this capability using the i/o port settings internal web page for the desired port (s1 for serial port 1 and s2 for serial port 2). change the port filter setting to at in order to enable at mode on that port and press the submit button to save the change. you must restart the sx-550 to make the change take effect. you can also use the console to enable the at capabilities. for example, the command set port s1 filter at enables at capabilities on serial port 1. note: if you use the at commands on the serial ports, you cannot use snmp traps or email alerts for that port (you can use the snmp traps and email filters on a different port and on the gpios). the at commands are described in detail in chapter 6. snmp traps, email alerts, and gpio status the sx-550 allows the user to define various alert conditions based on the state of the gpios or on data received by the serial port. for example, you could cause an alert to occur if the signal on gpio 3 goes low, or if a certain user-defined string of characters is received on the serial port. when an alert occurs, it can be sent as an snmp trap and/or as an email message. the sx-550 also allows the user to set the gpios or read the state of the gpio pins via console commands (console commands can issued through the console port, via the console mode switch feature described earlier in this chapter, via the at#c command described in chapter 6, or through telnet). in addition, you can use the sx-550 e-gpio capability to send the state of the gpio pins to a remote computer through tcp/ip messages at a user-defined time interval. details on using these capabilities can be found in chapter 6. part number 40183-101 silex sx-550 developer's guide page 39 bridge mode the sx-550 can work as a transparent bridge from ethernet to 802.11a/b/g. this is useful for allowing a device that have an ethernet interface to be used on a wireless network. operation is totally transparent, so there is no modification required to the devices software or firmware. bridge mode must be enabled through the internal command console. to do this, connect to the console as described in chapter 3 and enter the following commands at the local> prompt.: set nw bridge sin init exit there also commands to disable the bridging function and to select whether to use the wired or wireless interface for configuration purposes. note that you must also set up the normal wireless parameters such as ssid, mode, and security as described in chapter 3. the bridge mode commands are summarized in the following table: command description set nw bridge sin sets the device to bridge a single connected device. in this mode, only tcp/ip (telnet, http) can be used to configure the sx-550. set nw bridge dis disables bridging mode returning the unit to normal operation set nw brwired ena enables the wired interface as the active configuration interface. this is used for connecting to a pc via the wired port, typically to set up the wireless parameters. set nw brwired dis enables the wireless interface as the active configuration interface. this is the normal setting when bridge mode is active, because the wired port will usually be connected to the device being bridged. part number 40183-101 silex sx-550 developer's guide page 40 chapter 5 interfacing the sx-550 to the oem device in order to connect the sx-550 module to your device, you will need to provide either a custom daughtercard or a special cable. both of these solutions will require a 40-pin female connector on one side, with the appropriate connector(s) for connecting to your devices circuitry on the other side. the custom daughtercard is generally a superior solution because it provides better mechanical connections for greater overall system reliability. a good model for a custom daughtercard is the silex sx-550-6900 evaluation daughtercard (see chapter 2 for a discussion of the evaluation daughtercard). to assist you in the design of your daughtercard, we have therefore included the schematics of the evaluation daughtercard in figure 22. the major design considerations for the sx-550 are as follows: 40-pin oem header . this is the primary mechanism for communications between the oem device and the sx-550. this section describes the pinout and the mechanical considerations. antenna connectors. the two u.fl connectors can be used to connect a variety of antennas. ethernet phy transformer . if you are using ethernet, you will need to provide a transformer that meets the specifications outlined in this section. general purpose i/o (gpio). the gpios can be used to control leds and for a variety of other purposes. power. the power requirements for the sx-550 are stated in this chapter. each of these design considerations is covered in the following sections of this chapter. part number 40183-101 silex sx-550 developer's guide page 41 part number 40183-101 silex sx-550 developer's guide page 42 figure 22 sx-550 evaluation daughtercard schematics oem header

contains a simple network management protocol (snmp) agent that collects and stores management information for network managers using standard snmp commands. the management information is referenced as a hierarchically organized database called a management information base (mib) . to prevent naming conflicts, all of the manageable features of all products from all vendors are arranged in a single tree structure. each vendor of snmp equipment has an exclusive section of the mib tree. each branch of the mib tree has a number and name. the path from the top of the tree down to the point of interest forms the name of that point. a name created in this way is known as an object id or oid . part number 40183-101 silex sx-550 developer's guide page 54 table 21 describes the messages used to communicate between the network manager and the snmp agent, as defined in rfc 1157. each snmp message must contain a community name, which is used like a password. the default community name for the sx-550 module is public. table 21 snmp commands command description get retrieves management information for a specific managed object contained in the agent. the get message must contain the oid for the specified object. the response is a get-response message containing either the current value of the requested object, or an indication as to why the request failed. get next retrieves management information from a non-specific managed object. the get next contains either a complete oid or a fragment of an oid. the response is a get-response message containing either the oid and data of the item immediately right of the specified oid in the tree or an indication as to why the request failed. get response this is the information sent back from the unit in response to the get, get next command. set requests a change to the value of a specified object. the response is a get-response message with either an indication that the requested change had been made or with an indication as to why the request failed. trap sends a one-way notification from the agent to the manager that a significant event has occurred. this is the only message initiated by the snmp agent. to configure the snmp server settings: 7. log into the sx-550 internal web pages using a standard web browser. click server settings to access the screen shown in figure 10. you can then enter the relevant snmp information for your network. part number 40183-101 silex sx-550 developer's guide page 55 figure 11 snmp configuration 8. click the submit button to save the changes. you must then restart the sx-550 to make the changes take effect. configuring the general purpose i/o (gpio) lines the sx-550 module has eight general purpose i/o (gpio) lines available for use on connector j7. these gpio lines are individually programmable for either input, output, or special purpose. by default, six of the gpio lines are configured for special purpose use. lines configured for input can be used as a source for snmp traps and/or email alerts. the gpio direction, trigger settings, and email/web page message strings are configured from the internal configuration console interface. table 22 through 27 describe

gpio data table 26 e-gpio tcp monitor commands the e-gpio tcp monitor allows a computer system to access the sx-550 gpio pin values. if enabled, this monitor will attempt to make a tcp connection to the remote computer specified. once connected, the monitor will periodically send the state of the gpio pins to the remote computer. this monitor is configured via the console with the following commands: command description set gpio mon [en | dis] enables or disables the e-gpio monitor show gpio mon shows the current state of the gpio monitor. set gpio addr gpio set message format this message may be optionally sent by the remote computer when an e-gpio connection is active. this message allows the remote computer to set the state for any gpio pins configured as ouptus. this is equivalent to the set gpio data command. the message is in the format: gpio=00ab gpio direction control integer read-only gpio.2 this is an integer representing a bit mask indicating which gpio bits are configured for outputs. only bits for which the gpio bit mask is 1 are valid. a 1 indicates the gpio bit is an output, a 0 indicates an input. 7 6 5 4 3 2 1 0 gpio10 gpio9 gpio6 gpio5 gpio4 gpio3 gpio2 gpio1 gpio data integer read-write gpio.2 this is an integer representing a bit mask indicating the gpio bits status. on a read, the current value of the input pins is returned. output bits return the last value set. on a write, bits configured as outputs are set to the value given by the corresponding mask bit. for input bits, a write has no effect. 7 6 5 4 3 2 1 0 gpio10 gpio9 gpio6 gpio5 gpio4 gpio3 gpio2 gpio1 gpio trigger mask integer read-only gpio.2 this value is an integer representing a 32 bit mask expressed in hex digits. the mask is encoded as follows: 31 30 29 28 27 26

for example a hex value of 4 represents gpio3 0 to 1 transition (trig3) is enabled as a trigger. gpio transmit string table index integer read-only gpio.5.1.1.n this value is the index into the gpio message table for trigger number n. for the sx-550, this always returns n as its value. part number 40183-101 silex sx-550 developer's guide page 67 gpio transmit string value octet-string read-only gpio.5.1.2.n this item returns the gpio transmit string for trigger number n, if a string is defined. the string may be defined even if the corresponding trigger is not currently enabled. part number 40183-101 silex sx-550 developer's guide page 68 configuring serial port monitor alert and trap configuration the sx-550 module can be configured to scan and compare the data received on the serial port to user- defined strings. a match with a string can be a source for snmp traps and/or email alerts. the match strings and corresponding email or web page message strings are configured from the internal configuration console interface. table 28 describes the monitor alert and trap configuration commands.. table 28 port monitor alert commands command description show port s1 trigmon shows strings and index numbers being monitored set port s1 trigmon < trig # > setting up email alerts and snmp traps after you have created the gpio and/or serial port alerts and traps, you can the use the sx-550 internal web pages to set up the recipient email addresses and/or computer systems. after you have logged into the internal web pages, click alerts and traps on the left side of the screen and select either email alerts or snmp ip traps . the email alert configuration screen is shown below. this screen allows you to define up to eight email addresses that can receive alert information. each address can receive any combination of the alerts that you have defined previously. you must enter the ip address of your smtp server and the email address(es) where you want the alerts to go, and you must check the s1 or s2 box ( use on port ). for example, in the above screen, the user has configured two serial port alerts and two gpio alerts. he has decided to send one of the serial port alerts and one of the gpio alerts to the mail address admin@companyxyz.com . if desired, he could create up to seven more email addresses that could each receive any combination of these alerts. the snmp trap configuration page works exactly the same way as the email alert configuration page, except that you enter the trap community plus the ip address and port of the destination computer(s) instead of the email information. up to eight separate ip addresses can be configured with any combination of the alerts that you have defined. note that you may also use the console command set ip trap n trigger console command (see appendix b) to set up the traps. when you have finished configuring the alerts, be sure to click the submit button to save the settings. you will also need to restart the sx-550 in order for the changes to take effect. using at modem commands the sx-550 firmware has an optional data filter for configuring using at style modem commands with serial port 1. this feature allows devices with an existing at command interface to configure the unit, if the at commands can be properly modified. you must be familiar with the general operation of at commands. note that at command processing is not enabled by default. use the command set port s1 filter at to enable this feature. all commands begin with at and are terminated by a new line unless noted below. while standard at commands are defined to be 40 characters or less (not including the at), the server accepts commands of up to 80 characters. part number 40183-101 silex sx-550 developer's guide page 70 standard at commands supported the following standard at commands are interpreted by the device server. the data channel must be in the command mode for commands to be recognized. the data channel will be in command mode upon power up or reset. there are two operating modes for the unit when the at command option is enabled. in command mode, data received from the serial port is passed to the at command processor, and responses are returned to the serial port. no data is sent to any network application, and any data received from the network is ignored. in data mode, data from the serial port passes to the network application, and vice versa. this is equivalent to the normal serial port operating mode without the at command option. table 29 describes the at commands. table 30 details the extended at commands that allow the configuration of the network server operating parameters. any at command received, except the listed commands, are acknowledged with ok status. this allows existing modem applications to transmit commands without causing an error. these include at parameter command description echo control aten if n=0, commands are not echoed. if n=1, subsequent commands will be echoed. the default, upon unit reset, is for no echo (ate0). disconnect athn if n=0, any connection to a remote host is dropped. other value of n is ignored. return to data mode aton exits command mode and places the serial port in the data mode. all subsequent data is sent to the network application, if connected, until an enter command mode sequence is received. any value of n is ignored, if present. quiet mode atqn if n = 1, no result codes are returned. if n = 0, result codes are returned to the local device. 0 is the reset default value. verbose mode atvn if n = 0 and not in quiet mode, result codes are returned in numerical form. if n = 1, results are returned as text. 1 is the reset default value. table 30 extended at commands parameter command description console pass through at#c response codes table 31 details the response codes for codes other than #c commands. table 31 response codes numeric code description 0 ok 2 no carrier 4 error 5 connect 8 no answer using extendview for bulk configuration the extendview utility has a powerful bulk configuration capability that allows you download configuration information to multiple sx-550s simultaneously. this can save you a significant amount of time compared to configuring each sx-550 individually. to use this capability: 1. from the extendview menu bar, select view and then multi-select mode . 2. the display will change slightly so that there is checkbox by each of the sx-550s listed on the main screen. click the boxes next to each of the sx-550s that you wish to configure. 3. from the extendview menu bar, select server and then multiple configuration . the configure multiple devices window will appear. this window lets you set parameters such as subnet mask, router address, basic wireless security, and much more. when you have set all of the desired parameters, click ok and the parameters will be downloaded into the selected sx550s. part number 40183-101 silex sx-550 developer's guide

psk authentication, you would need to set the wpa-psk pre-shared key and enable or disable the wpa group key. likewise, if you are using wpa2 with 802.1x tls authentication, you would need to enter a user id and password, an authentication certificate, and a private key. the following is a description of the authentication settings used by the sx-550: part number 40183-101 silex sx-550 developer's guide page 78 encryption mode (wireless security only) the possible sx-550 wireless encryption modes include: 64 and 128 bit wep. these are available for basic wifi compatibility. because of known security issues, wep should be avoided if possible. dynamic wep . dynamic wep uses wep encryption with an 802.1x eap authentication method. it is not necessary to set keys with this method, because they are automatically assigned. wpa2 . wpa2 is the latest and strongest wireless security standard. it uses uses ccmp encryption. like wpa, it can be used either with a pre-shared key or with 802.1x authentication. wi-fi protected access (wpa ). wpa uses tkip encryption, and can be used with either a pre- shared key (psk) or with 802.1x authentication. wpa2-wpa . this mode combines the capabilities of wpa2 and wpa by using ccmp for pairwise encryption, but allowing tkip for group encryption. to set the encryption mode, select the desired mode from the pull down menu on the configure network security screen in the sx-550 internal web pages, or use the console command set nw enc wireless authentication type (wireless security only) this parameter sets the type of authentication to be performed with the network access point (radius authentication server), or with a peer unit in ad hoc mode. the sx-550 supports shared key and open system authentication with wep, and psk, tls,

and other agency requirements are the responsibility of the oem . modular approval information (sx-550-2701 only) the sx-550-2701 is modular approved, which means that it allows a module vendor to certify that his wireless module meets fcc part 15 subparts c and e and rss-210 intentional radiation standards. any oem device that incorporates a wireless module that has modular approval does not need to go through the fcc part 15 subparts c and e or rss-210 intentional radiation testing process. modular approval therefore greatly simplifies the approval process and substantially reduces the cost of testing. there are specific requirements for using the sx-550-2701 modular approval, including: 1. you must put the sx-550 fcc or ic number in a visible location on your product. these numbers are as follows: a. fcc: n6c-sx10wagit b. ic: 4908b-sxsx10wagit 2. you must use either a silex-supplied sx-550 antenna (part number 108-00016-050) or a pole antenna similar to the one shown in appendix c. if you use a non-silex antenna, it must have a gain that is less than or equal to 2.1dbi @5.825ghz or 1.5dbi @2.4ghz. if you do not use a pole antenna, the limited modular approval no longer applies and you must recertify your product for compliance with intentional radiation regulatory requirements. 3. you must use either the silex-supplied sx-550 antenna cable (part number 131-20110-050 ) or use a cable that meets the specifications shown in appendix c. 4. there must be at least 20cm between the sx-550 antenna and the human body to avoid the possibility of exceeding the fcc radio frequency exposure limits. if your device requires smaller distances, then you must test your device as a system with the sx-550 for compliance with specific absorption rate (sar) requirements. part number 40183-101 silex sx-550 developer's guide page 107 important : modular approval only covers intentional radiation requirements. although the sx-550 is designed to comply with fcc part 15 subpart b class b unintentional radiation requirements, it is your responsibility to ensure that your device complies with unintentional radiation requirements when the sx-550 is installed. fcc information (sx-550-2701 only) fcc id: n6c-sx10wagit notice in accordance with fcc part 15, the sx-550-2701 is listed as a modular transmitter device. end products that include the sx-550-2701 shall have the words contains transmitter module fcc id: n6c- sx10wagit on an exterior label. this equipment complies with part 15 of the fcc rules. operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. this equipment has been tested and found to comply within the limits for a class b digital device, pursuant to part 15 of the fcc rules. these limits are designed to provide reasonable protection against harmful interference in a residential installation. as noted in the previous section, however, it is the responsibility of the oem to ensure that his device meets the limits for a class b digital device when the sx-550-2701 is installed in it. this equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. however, there is no guarantee that interference will not occur in a particular installation. if this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: reorient or relocate the receiving antenna increase the separation between the equipment and receiver connect the equipment into an outlet on a different circuit from that to which the receiver is connected consult the dealer or an experienced radio/tv technician for help. the transmitter must not be co-located or operated in conjunction wit any other antenna or transmitter. the available scientific evidence does not show that any health problems are associated with using low power wireless devices. there is no proof, however, that these low power wireless devices are absolutely safe. low power wireless devices emit low levels of radio frequency energy (rf) in the microwave range while being used. whereas high levels of rf can produce health effects (by heating tissue), exposure to low-level rf that does not produce heating effects causes no known adverse health effects. many studies of low-level rf exposures have not found any biological effects. some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. to satisfy rf exposure requirements, this device and its antenna(s) must operate with a separation distance of at least 20 centimeters from all persons and must not be co-located or operated in conjunction with any other antenna or transmitter. end-users must be provided with specific operating instructions for satisfying rf exposure. fcc warning: changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. part number 40183-101 silex sx-550 developer's guide page 108 information for canadian users (ic notice) (sx-550-2701 only) ic id: 4908b-sx10wagit the term ic before the radio certification number only signifies that industry canada technical specifications were met. operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. this class b digital apparatus meets all requirements of the canadian interference-causing regulations. to prevent radio interference to the licensed service, this device is intended to be operated indoors and away from windows to provide maximum shielding. equipment that is installed outdoors is subject to licensing. this device has been designed to operate with an antenna having a maximum gain of 2db. antennas having a higher gain are strictly prohibited per regulations of industry canada. the required antenna impedance is 50 ohms. to reduce potential radio interference to others, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (eirp) is not more than required for successful communication. the device for the band 5150-5250mhz is for indoor usage to reduce potential for harmful interference to co-channel mobile satellite systems. the available scientific evidence does not show that any health problems are associated with using low power wireless devices. there is no proof, however, that these low power wireless devices are absolutely safe. low power wireless devices emit low levels of radio frequency energy (rf) in the microwave range while being used. whereas high levels of rf can produce health effects (by heating tissue), exposure to low-level rf that does not produce heating effects causes no known adverse health effects. many studies of low-level rf exposures have not found any biological effects. some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. rohs declaration of conformity (all sx-550 models) silex technology, inc. declares that the sx-550

109 part number 40183-101 silex sx-550 developer's guide page 110 appendix e firmware update procedures occasionally it may be necessary to update the sx-550 to take advantage of new features or to fix specific problems. the simplest way to perform this update is with the silex updateip utility for windows xp and 2000 computers. this utility can be found on the cd-rom that is included with the sx-550, or it can be downloaded from the support & downloads section of the silex website ( www.silexamerica.com ). to use updateip: 1. download the appropriate firmware update file from the support & download section of the silex website ( www.silexamerica.com ) into a directory on your computer. 2. download or copy the updateip software files into a directory on your computer. 3. double click the updateip.exe icon to start the updateip application. 4. click ok when you get the about update for tcp/ip splash screen 5. when you get the select update file screen, locate the firmware update file that you downloaded in step 1, and double click on the file name. 6. you will get the update files screen. the firmware update file that you selected should appear on this screen. click ok . 7. the program will search the local network for sx-550s. click ok when the search process is complete. 8. a list of available sx-550s will appear. highlight the sx-550(s) that you wish to update. 9. from the menu bar, select update and then start to update the sx-550(s). if you cannot use updateip, you can use the trivial file transfer protocol (tftp) to update the serial device server firmware: part number 40183-101 silex sx-550 developer's guide page 111 important: make sure that the updateip application is included as an exception if you have a firewall enabled on your pc. important : once a firmware update begins, the power led will flash and the unit should not be powered off while the led is flashing. the firmware update process can take several minutes after the transfer has completed. 1. download the appropriate firmware update file from the support & downloads section of the silex website ( www.silexamerica.com ) into a directory on your computer. 2. if you are using windows 2000, xp, or vista, enter the following command from the command line of your operating system: tftp -i ipaddress put filename access where ipaddress is the ip address of the serial device server, filename is the file name (and path, if necessary), and access is the serial device server password (if you changed this password, use your new password instead of access). for example, to download the file tathsti130.bin from the updates directory on your computer into a serial device server with an ip address of 192.168.5.70, you would enter the command: tftp -i 192.168.5.70 put /updates/tathsti130.bin access if you are using a different operating system, please refer to the documentation of that operating system for information on how to use the tftp command. note that you should specify that the tftp destination file is the serial device server password (access by default). part number 40183-101 silex sx-550 developer's guide page 112 important : once a firmware update begins, the power led will flash and the unit should not be powered off while the led is flashing. the firmware update process can take several minutes after the tftp transfer has completed. appendix
