introduction 1 1. introduction congratulations on your purchase of a DI-500/510 or di-750/760 series data acquisition/measurement system. these instruments permit data acquisition on ibm personal computers and compatibles from the windows environment. this manual describes how to connect and use the DI-500 /510 and di-750/760 series instruments. from an opera- tional point of view, all of the instruments are approximate ly the same. throughout the majority of this manual, enough similarity exists to describe each instrument with th e same procedure. the conventions used to describe these universal applications are ?d i-500 series? (which means that the proce dure/information applies equally to the di- 500-16, DI-500-32, di-510-32, di-510 -48, di-510-64, or any of the chan nel expansion instruments), ?di-750 series? (applying to the di-750-16 and di-750-32) and ?di-760 series? (applyin g to the di-760-32, di-760-48, and di-760-64). in cases where the resemblance is not equal, separate procedures/descriptions exist for each instrument. features the DI-500/510 and di-750/760 series offers the following features: ? complete portability. connects to the parallel port of a ny desktop, transportable, notebook, or laptop pc-compat- ible computer. ? per channel software-configurable settings: input gain ; signal averaging; input and output measurement range. ? 250khz burst sampling to minimize channel skew. ? eight each digital input and output lines. ? a/d subsystem provides 14-bit resolution. ? d/a subsystem provides 14-bit resolution. ? programmed i/o (pio ) data transfers. ? signal averaging of up to 32,768 consecutive readings per channel. free

are included with a typical DI-500/510 or di-750/760 series system. verify that you have the following: ? the DI-500/510 or di-750/760 series instrument ? communications cable assembly designed to connect the instrument to your computer's parallel (or printer) port ? power adapter and power cord ? activex control library with built-in documentation ? this hardware manual. if an item is missing or damaged, call dataq instruments at 330-668-1444. we will guide you through the appropri- ate steps for replacing missing or damaged items. save the original packing material in the unlikely event that your unit must, for any reason, be sent back to dataq instruments, inc. connecting the instrument to your computer DI-500/510 and di-750/760 series instrume nts use your computer?s parallel (or printer) por t to interface digital and analog signals to your computer. instal lation is as simple as connecting the provided communications cable to your computer. 1. plug the appropriate end of the supplied communications cable to the 25-pin female connector labeled printer port on the DI-500/510 or di-750/760 series instrument. 2. connect the other end of the cable to your computer's parallel port. free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual getting started 6 applying power use the following procedure to apply power to your DI-500/510 or di-750/760 series instrument: 1. plug the five-pin din end of the power adapter to the connector labeled power input on the instrument. 2. plug one end of the supplied power cord into the power adapter and the other end into any standard 120vac, 60hz, single-phase outlet. if an alternate power source is to be used, refer to the following pin-out diagram for power requirements. 3. turn the power switch to on. connecting your signals on portable DI-500/510 series instruments, all analog input signal connections are made to the sheathed banana jacks or to the screw terminals. on desktop di-750/760 series inst ruments, all user connections are made to the screw ter- minals on the back of the instrument. for bare wire signal leads (such as ther mocouples): (1) insert the bare wire into the desired terminal directly under the screw; (2) tighten the screw by rotating clockwise with a small screwdriver. make sure the screw tightens only free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual getting started 7 against the signal wire and not the wire insulation. do not overtighten; and (3) tug gently on the signal lead to ensure that it is firmly secured. analog inputs DI-500/510 and di-750/760 series instruments may be conf igured to connect 16, 32, 48, or 64 (model dependent) differential analog channels (expanda ble to 240 channels with optional expansion instruments). analog signals may be connected to the banana j acks or to the screw terminal connectors. the high level anal og inputs are intended for a full scale measurement range of 10v; signal-conditioned in puts are intended for a full scale measurement range of 5v (if 5b module socket is bypassed - otherwise the full s cale measurement range is determined by the 5b module). the maximum input voltage without damage is 30v. when needed, per-channel transducer exc itation is built-in (5b module dependent), eliminating the need for external power supplies. connecting a differential amplifier differential inputs allow the DI-500/510 or di-750/760 seri es amplifier to detect the difference in voltage between the high (+) and low (-) inputs. differential amplifiers have the advantage of reducing common mode voltages (i.e., those appearing simultaneously and in phase on both inputs). this capability may be leveraged to great advantage to reduce noise riding on a signal of interest. two signal measurement conditions govern configuration of a differential channel input: (1) the signal to be mea- sured is ground-referenced; or (2) the signal to be measured is isolated from ground. the signal that is isolated from ground requires no special consideration when connecting to a differential amplifier, however the ground referenced signal does. ground-referenced signal sources a ground-referenced signal source is one with a local ground that may not be (and probably is not) at the same poten- tial as the computer's ground. this potential difference be tween signal and computer ground is referred to as a com- mon mode voltage and is caused by a number of different factors. the most common of these is different p hysical locations of the computer and signal ground points. since wire is not a perfect conductor (i.e., e xhibiting zero resistance regardless of length) a voltage drop, however small, will always 9 6 l j q d o 6 r x u f

getting started 8 be present. the differential amplifier is unique in its ability to measure signals originating from sources with different ground potentials relative to the computer providing it is connected properly. the most common error made in connecting differential amplifiers is the tendency to ground both ends of a signal shield. this causes current to flow through the shield and induces noise on the signal to be measured. this problem is eliminated by ensuring that only one ground exists on the signal circuit. 6 l j q d o 6 r x u f h ' l i i h u h q w l d o $ p s o l i l h u j q g 6

application requiring a differen tial amplifier also defines a need for quality signal cable. four elements combine to ensure adeq uate quality signal cable: a twisted signal pair with low resistance stranded copper conductors; surrounded by a multiple-folded foil sh ield; with a copper strande d drain wire; all contained within an insulated outer jacket. in applications where such signal cable is used, a dramatic decrease in noise pickup will be experienced. the drain wire should be considered as the shield and should be c onnected as described in the section titled ?connecting a dif- ferential amplifier? on page 7. signal cable meeti ng all four criteria for quality is belden no. 8641. labeling analog input channels depending on the number of analog input channels your instrument has, it may be necessary to label them. for exam- ple, say you are using a di-510-64 or a di-760-64 to record 64 analog input channels and you want to record the sig- nal connected to channel 28. looking at the instrument, ther e are two groups, or ?banks,? of 32 inputs. each bank consists of channels 1 through 32 (6 4 total inputs). since there are two channels labeled 28, how will you know which one will be recorded? a small box is provided on the instrument panel to label banks of channels and avoid this prob- lem. in order for you and the software (either w in d aq or the activex control library) to tell these inputs apart, label each bank of 32 inputs with a letter according to the following table (an ordinary pencil is sufficient): if you are using this instrument by itself (not multiplexed with other instruments): ?then write this letter in the box on the overlay: di-750-16 DI-500-16 not required di-750-32 DI-500-32 ?a? di-760-32 di-510-32 ?a? di-760-48 di-510-48 not

& r s s h u & r q g x f w r u v free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual getting started 10 for example, in the previous 64-channel example, the first or top bank of 32 channels now become channels a1 through a32 and the second (the bottom bank on portable mode ls) bank of 32 channels become channels b1 through b32. the ?channel 28? ambiguity disappears, th e channel in question is either channe l a28 or channel b28. note that the above table is for stand-alone instruments only. if you ha ve several DI-500/510 or di-750/760 series instruments multiplexed together, refer to the following section for labeling information. increasing the total anal og input channel capacity the 37-pin connectors (labeled auxiliary port and expansion on DI-500-16, di -750-16, di-510-48, and di-760-48 instruments, or expansion in and expansio n out on all other instruments) are used for system expansion. additional DI-500/510 and di-750/760 series inst ruments can be ?daisy chai ned? together to increase channel capacity. up to 240 analog channels can be acquired by connecting combinations of DI-500/510 and di-750/ 760 series instruments together. the following illustration shows a typical 128 channel configuration, consisting of a di-510-64 (64 input portable instrument) and a di-510-64-x (64 input portable expansion unit): when several instruments are connected together, one instrument becomes the ?master? inst rument and all others become ?slave? instruments. the ?master? is always defined as the in strument connected directly to the pc. a ?slave? is defined as an instrument that is connected to the master (or not connected directly to the pc). note that it is possible to have any number of slave instruments in a conf iguration (up to 240 total channels), but always only one master instrument. the expansion cable is always conn ected from the expansion ou t port to the expansion in port of the next instrument, moving in a direction away from the pc. the DI-500-16, di-750-16, di-510-48, a nd di-760-48 are master instruments only. they can be expanded (by adding slave instruments) but they can neve r be used as a slave instrument. all of the expansion instruments in the DI-500/510 and di -750/760 series (i.e., di-5 10-32-x and di-760-32-x) are slave instruments. they have no printer port so they can never be configured as a ma ster instrument (connected directly to the pc) and cannot be used alone (they must be connected to a master instrument). the di-510-32, di-760-32, di-510-64, a nd di-760-64 instruments can be used as masters or as slaves. they can be connected directly to the pc as stand- alone master instruments or they can be connected as slave channel expansion printer port to printer

instrument, moving in a direction away from the pc. when using several instruments in a master/slave configurat ion, label the instruments to avoid confusion. using the same example as above, say you have a di-510-64 (64 input portable instrument) and a di-510-64-x (64 input porta- ble expansion unit) multiplexed together and want to record the signal connected to channel 28. looking at the instru- ments, there are four groups or ?banks? of 32 inputs, each ba nk consisting of channels 1 th rough 32 (128 total inputs). since there are a total of f our channels labeled 28, how will you know which one will be recorded? a small box is provided on the instrument panel to label banks of channels and avoid this problem. in order for you and the software (either w in d aq or the activex

example, the 64 master instrument channels now become channels a1 through a32 and b1 through b32 and the 64 slave instrume nt channels now become channels c1 through c32 and d1 through d32. the ?channel 28? ambiguity disappears, the channel in question is either channel a28, b28, c28 or d28. if you are using this instrument as the master instrument: ?then write this letter in the box on the

accessible items on the DI-500/510 or di-7 50/760 series instrument. analog inputs the analog inputs allow you to connect your input signals to the instrument. all portable instruments in the series allow dual-access connections (eith er to the sheathed banana jacks or to th e screw terminals). all desktop and rack- mounted instruments support only screw terminal signal connections. refer to the section titled ?connecting your signals? on page 6 for more analog input details. signal conditioning module interface allows you to plug di-5b signal conditioning modules into a channel on the instrument. each di-5b module filters, isolates, amplifies, converts, or othe rwise conditions your input signal (i.e., the output from a thermocouple, strain gage, lvdt, etc.) so it becomes suitable for a/d conver sion by the DI-500/510 or di-750/760 series instrument. when a di-5b module is installed, the input signals are conditioned from either the sheathed banana jacks or the screw terminals. note that not all input signals require signal conditioning. on instruments with only high level inputs (such as the di- 500-32 or di-750-32 and the di-510-64 or di-760-64), these signal conditioning module interfaces are not needed and therefore are covered. 3 5 , 1 7 ( 5 3 2 5 7 $ & 7 , 9 ( 3 2 : ( 5 3 2 : ( 5 6 : , 7 & + 9 ' & # $ 0 $ ; 3 2 : ( 5 , 1 3 8 7 ( ; 3 $ 1 6 , 2 1 , 1 ( ; 3 $ 1 6 , 2

channel(s), you are ready to install and run the software. there are two software approaches for DI-500/510 and di -750/760 series instruments: writing/developing your own acquisition, review, and analysis programs or using w in d aq software. for the programmers who will be writing their own acquisi tion, review, and analysis programs, dataq instruments, inc. provides an activex control library free with every dataq instrument purchased. the activex control library is installed automatically when you install any version of w in d aq software and comes with its own built-in documentation. for non-programmers, or for those who want convenience, dataq instruments, inc. provides w in d aq software. w in d aq is easy to use, ready-to-run, data acquisition, review, and analysis software for the windows? environ- ment. w in d aq /lite recording and playback soft ware is included free with ever y dataq instrument purchase. w in d aq / lite recording software is limited to 16 channels and 24 0 hz maximum throughput when you enter the record mode. if you do not want to program and your application does no t require more than 16 channels or a recording throughput more than 240 hz, then you will want to install w in d aq /lite software. find the w in d aq /lite software package (manuals and cd-rom), and pr oceed with the inst allation instructions

to enable analog channels for recording. for example, suppose you have analog signals connected to channels 1 through 16 and you want to record all of them. use this procedure to enable channels 1 through 16 for recording. 1. to enable channel configuration: click on channels... in the edit menu. what you see on your monitor depends on which instrument you are using: DI-500-16 and di- 750-16 instruments used alone the ch: block cursor will blink in the channels field on the status bar. the currently activ e list of enabled channels are displayed in this field, immediately to the left of th e cursor (initially, only channel 1 is enabled for recording). 2. enter the desired channel number an d press the enter key. repeat for each desired channel. this causes the channel number to be displayed in the enabled channels row. 3. when all desired channels have been enabled, exit the channe l configuration routine by pressing any key other than the letters d and i. note that a channel may be removed by typing the channel number preceded by a minus (-) sign. for example, typing ?-3? removes channel 3 from the row. note also that ch annels may not be added after the record mode has been entered. free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual enabling channels for acquisition 16 all other DI-500/510 and di -750/760 series instruments this displays the channel selection grid: each box in this grid represents an input channel. an in put channel is enabled by clicking the desired box. where in the grid you click, which mouse button you click with, a nd how many times you click the mouse button determines whether the input channel is enabled for differential operation, for operation defined by the 5b module (if used), or for differential operation between a pair of channels (automatically defined by the grid). since th ere are so many vari- ables, each instrument will be presented individually. DI-500-16 and di-750-16 inst ruments used with ?slaves? channels 1 through 16 are enabled on the top row of the grid. when other instruments are connected as a slave to the DI-500-16, their ch annels are enabled starting with row ?mux a? (and ?b,? etc. when more than 32 channels ar e multiplexed). using an ordinary pencil, label all slave free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual enabling channels for acquisition 17 instrument channels by writing the letter from the grid in the box on the inst rument panel overlay (i.e., place an ?a? in the box to designate slave channels a1 through a32). if a second DI-500-16 is multiplexed as a slave to the first DI-500 -16, enable all 32 channels on the top row of the grid (no other expansion is permitted when two DI-500-16's are multiplexed). in this case, the expansion cable is con- nected from the expansion connector on the master to the auxiliary port connector on the slave. point to the box in the grid that represents the desire d channel and click the left mouse button to enable the channel as a differential input (when not using 5b modules) or as an input defined by the 5b module (when used). a check mark is displayed in the desired cha nnel box, indicating that a differential input (when not using 5b modules) or an input defined by the 5b module (when used) has been enabled. a second activation removes the check mark and thus disables the channel. point to the box in the grid that represents the desired channel and double-click the left mouse button to enable a pair of differential channels for di fferential operation (this allows you to see the difference between 2 differ- ential input channels). a plus sign (+) is displayed in the desired channel box, indi cating one differential chan- nel and a minus sign (-) is automatically displayed eight ch annels away (i.e., channels 1 and 9, 2 and 10, 5 and 13, etc.), indicating the other differential channel. you can sele ct the first or positive channel (from 1 through 8), but the second or negative channel is automatically selected by the software. clicking the left mouse button on the plus sign removes both plus and minus signs and thus disables the channel pair. this configuration is useful anytime you need to monitor the difference between two diff erential input channels. for example, say you are monitoring the temperature of a long, narrow widget. you want the widget to be of uniform temperature throughout its entire length. you could use two thermocouples (one per channe l, on each end of the wid- get) to monitor temperature. the temperature of one end of the widget would be measured by one thermocouple and the temperature of the other end of the widget would be measured by the other thermocouple. however, in the differ- ential channel pair configuration as described above, onl y the difference between the two thermocouples would be reported by w in d aq software. this difference in temperature could then be used to control a process (i.e., if one end is 5 hotter than the other, then turn on a heat er to evenly distribute the widget temperature). point to the box in the grid that represents the desired channel and click the right mouse button to enable the channel as a digital input. an ?i? is displayed in the desired channel box, indicating that a digital input has been enabled. pointing to the ?i? and clicking the left mouse button re moves the ?i? and thus disables the channel. the digital inputs are connected to the 37-pi n auxiliary port connector on the DI-500-16 instrument. note that when you specify a channel as a digital input in the channel selection grid, you no longer have the ability to connect an analog signal to that channel either at the sheathed banana jacks or at the screw terminals. free datasheet http:/// DI-500/510 series and di-750/760 series hardware manual enabling channels for acquisition 18 DI-500-32 and di-750-32 instruments ignore the top row. channels 1 through 32 are enabled on the second row from the top (row ?mux a?). when other instruments are connected as a slave to the DI-500-32, their chan nels are enabled starting with row ?b?

excitation is provided from the module by two matc hed current sources. when usi ng a three-wire rtd, this method allows an equal current to flow in each rtd lead, which cancels the eff ects of lead

ent applications requiring a very high level of accuracy, the di-5b35 4-wire rtd input module offers a significant advantage over 3-wire measurement techniques (see block diagram). the di-5b35 measures only the voltage dropped across the rtd and almost completely ignores the resistance or length of the rtd lead wires. the di-5b34 3-wire rtd m odule provides lead resistance compensa tion, but requires equal lead resis- tances, while the di-5b35 does not require matched lead resistances. each di-5b35 rtd input module provides a single channel of rtd input which is filtered, isolated,

the two input signal measuring leads. the excitation current does not flow in the input signal leads, which allows rtd measurement to be totally independent of lead resistan ce. the excitation current
