Chuptev 1: h t d u c t i o n &J ZnstuZZation of the DATAshuttle

Thank you for selecting the DATAshunie for your project! Our primary objective is to provide you with data acquisition systems that are easy to install, operate, and maintain. We also strive to fumish the perfor- mance you need at the lowest overall cost. The benefits for you are increased productivity, data you can count on, and, of course, meeting your budget. We manufacture the DATAshuttlc as an enhancement product that readily plugs into the parallel port of an IBM, or compatible, desktop or portable com- puter. The product's high noise rejection. input protection to withstand as much as 50 Volts, and guaranteed long term stabiiity make it ideal both for the labora- tory and for harsh industrial environments. With its parallel pon interface, built-in terminal panel, and compact. light size, the DATAshuttlc is also com- pletely portable, providing for a quick and easy set-up in both in-house labs and remote test sites. Using the DATAshuttIc together with our graphical interface application soft- ware (such as WorkEknch PC" for Windows or DOS, or Quickiogm PC), you can easily and very quickiy implement a broad spectrum of research and commercial tasks, in a wide variety of settings. You can, for example,

shude OWNFD'S MANUAL - í Informólion

DEVELOPMW People who decide, on the other hand, to write their own software SYSTIEM (rather than using an off-the-shelf application) can employ the

Analog Connection Development Systemm hardware driver to address al1 features of the unit from within a program they design and code for their specific purpose.

XPANDABIUTY Al1 DATAshuttles have eight differential anaiog input channels and 8 digital inpudoutput lines; and you can add one DATAshuttle at a time to your computer, for as many as 15 units with a total of 120 analog input channels and 120 digital VOS!

RANGES/ The six input ranges of the DATAshuttle span from 50 milliVolts S OF MEASURE through 10 Volts DC, making it capable of accepting data from al-

most any sensor. You can, as well, insta11 a resistor, making the DATAshuttle capabie of DC current measurements. Its high accuracy makes the DATAshuttle ideal for precise evalua- tions in the laboratory or field. ?he DATAshuitle together with our software - such as WorkBench PC for Windows or DOS and QuickLog PC - make it easy to spec- ify engineering units (degrees, volts, milliAmperes. etc.) for mea- surements, as well as which ranges to use. (You can measure temperature, for example, by selecting from among 11 different thermocouple types, or from a wide variety of resistance temperature devices - RTDs. With the application soft- ware, the process simply consists of selecting the type of sensing device from a menu - the driver itself automatically handles cold junction compensation and linearization.)

DATA The combination of Strawberry Tree hardware and application PRESENTATION software (WorkBench PC for Windows or DOS or QuickLog PC)

enables both the display of data on the screen, and the logging of data to disk for later analysis. ihe system is capable of showing data on the monitor in a variety of formats. On-screen meters can provide accurate nadings of any parameter on any channel. Chan displays can indicate trends for comparison of actual measurements on several channels. or for setting data points or alarms.

DYNAMIC Al1 DATAshuttles incorporate "Dynamic Resolution," which .

With this feature, resolution is greater at the lower (negative) , of any range than at the higher end. As your readings approa< the low end of any gtven range, the resolution becomes finer ( i

is, the increments of the signal you can distinguish become smaller) .

RESOl.l,lllON improves the unit's accuracy.

Dynamic resolution improvement is most noticeable when th signal remains below a 10% of full scale threshold (approxi- mately). Our products, consequently, are the best available fc taking accurate measurements of low-leve1 signals, as you wc using a thermocouple sensor. Dynamic resolution is always best toward the negative end of range: Figure 1. Dpmk Resolutian for oissimilar Rmger -

DATAshuttle Model Variations

The DATAshutile family Iine oífers 4 basic model variations, some available with either 12- or 16-bit resolution and 2 optional ana- log outputs, for a total of 14 model types.

D A T b M e G P i he DS12-8-Gt pS-ló-8a DS-lZS-GP-AO, and DS-ló-&GP-AO are general purpose units designed for al1 types of inputs. The DS-GP features terminals for 8 differential analog inputs and 8 digital VO lines, with rmm for up to 8 high-power optically isolated modules. Two analog outputs are available on the - A 0 modeis.

DATAshuH/e-XXX The DS-12-8-XXX. DS-16-8-XXX, DS-12-8-WO(-AO, and DS- 16-8-XXX-A0 are specifically designed for high accuracy RTD rneasurements. The DS-XXX (XXX specifies set resistor value in KRS) has signal conditioning set resistors pre-installed at the factory for use with 2- or 3-wire RTDs. This model also features terminals for 8 digital ü0 lines, wth room for up to 8 optically isolated modules. Twn analog outputs are available on the - A 0 models. The DS-XLY can also measure non-RTD inputs. For channels that are required 10 ineasure other signals, remove the pre-installed resisiors at R 3 and R4. See example in the Analog Auxiliary Com- ponents section of Chapter 2 for a more detailed illustration. Figirrc 2. lllusrrurion of fhe DArllchurrk-GP und DAiAshonk-XXX -

[khdt/esB The DS-12-8-5B and DS-16-8-58-A0 offer [he most compact solutions available for electrically isolating analog inputs, analog outputs, and digital VOS - al1 in one package. Up to 1506V isola- tion is available when installed with the optional -5B modules. The DS-5B5 encasement is custom-designed to support the installation of these -5B modules. The DS-5B features terminals for 8 differential analog inputs and 8 digital VO lines; two analog outputs are available on the - A 0 models. For maximum accuracy, each channel has a temperature sensor for thermocouple cold junction compensation. Excitation terminals for dnving strain gauges are also included on each channel. In addition, each channel can accept current sense resis- tors for 4-2OmA measurements. Before insialling isolation modules, i t will be necessary to remove jumpers. Note also that if two outpul isolation modules are installed, only six analog inputs are available for isolation. Odd- numbered channels (1,3.5 or 7) should be used to track Analog Output 1 (AOI) and even-numbered channels for Analog Output 2 (AO2).

Be you wish to install, simply connect the parallel input port o that DATAshuttlt to the passthrough pon of the prcviously installed DATAshuttlc. You may use the additional DB-25 cable to do this. or you can plug the next DATAshuttlc directly into t previous one. if you prefer to keep the units separate, you mal also connect additional DATAshuttlcs directly to any or al1 of tl other parallel ports on your computer. i .

In any of these ways, you may connect up to 15 DA'LAshuttlts one computer.

Piease note, however, that only two DATAshuttlcs may be PO ered off the same 6V, 1 amp AC Adapter. Therefore, you mui connect a new AC Adapter (see Step 3 above) to every third DATAshuttle in a series. This number may vary outside the 1.

( A n o N The DS-5B models are shipped with a 5V DC, -2.5A regulat adapter instead of the standard 6V adapter. If you are using 5B model(s) in your installation, note that each of those unit! A require its own adapter. A Note on Bomd Numbers- When you are using multiple unit: your installation, each unit needs to have an identity, or "bo number," for the software to recognize it as "individual." When the software is loaded, it will conduct a search for al1 installed hardware. scanning first for in-system boards and t for any DATAshuttles connected to the parallel ports.

Aux'llARr Most common sensors can be connected without the use of aux coMpoNEm i a v components. Some of the sensor installations (bridges, RTI

CirCuits, ioltage dividers and current sensors), however, requirc auxiliary components. These components can be installed on tl DATAshuttlc for convenience. This requires soldenng and some familiariry with electronics. In the examples in the Applications Rcftrcnct Manual, and the following, the component locations a shown but not the component values; you must calculate the v ues if they are not supplied with the sensor. f i e first step is to remove the daughterboard from the unit, as you will need full access to it for soldenng on the auxiliary con ponents. To do this, simply remove the four screws in the cornt of the daughterboard and lift it off of the DATAshuttlc. When using analog auxiliary components R1, R2, and R5 you must cut the shorting metal trace that connects the two ends n the line together before installing any of the components in tha locations. Use a sharp knife to carefully slice through the trace without cutting additional traces. In the case of R5 this is a plas covered metal wire. Diagrams of the auxiliary component area hole functions, and connection possibilities are shown on the 1 lowing page. NOTE: Analog auxiliary components are not available on DS-' models

POWER SUPPUES A Nofe on Power Suppfies -The DATAshuttfc supplies the follow voltages to power transducers, strain gauges, etc. The currentc available to the user are limited as follows:

The DATAshuttle can rneasure currenrs up to 50 mA directly. I 24.9 Ohm precision resistor needs to be installed in the auxili. component ares to do so. This connection for current measurl ment is shown below. (To see how this connection adds to thc circuit, refer to Figure 6(a).) R3 is used as a shunt resistor acrc the positive and negative lines of the channel in use. To instail this resistor, push the resistor ends through the hok for R3 (from the terminal side) until the resistor lies flat with panel surface. On the back side, solder the wires to the holes, : then clip off the extra wire with pliers. This connection does I require any additional traces to be cut. Be sure to select current measurement in the software packag that you are using. This installation allows the rneasurement voltage across the resistor and the conversion of this measure ment to current using the equation V=lR. Observe the power ing of the resistor you insta11 at R3. Space is provided for a 1/ Watt resistor.

However, if you need to install these resistors yourself then do the following: Figure 10 and Figure 11 show the possibie loca- tions of R3 and R4. Figure 7 will show you that R3 and R4 need to be connected as in Figure 14. R5 is already in place and should not be removed. To install these resistors push the resistor ends through the holes for R3 and R4 as shown in Figure 10 (from the terminal side) until the nsistor lies flat with the panel surface. I f two wires cannot fit into the Vref hole then one wire may be sol- dered to another that is already inserted. On the back side solder the wires to the holes. Then ciip off the extra wire with piien. The auxiliary component ana in question will now look like Fig- ure 14. This connection does not require any additional traces to be CUt. f p 14.3-wm m hmectfm -

kaaQie 3: Ground h p s Occasionaiiy there is an installation where the ground connection is made at thc sensor, but it i s riot reliabie. The solution to this 'intemittent" ground is to replace the COM to GND(A) jumper wire at R5 (Figure 6(a)) with a 10 Megohm, 5%, 1/4 Watt resis- tor. This provides a ground reference for the analog inputs in question, but allows very little ground current to flow. In very n o w environments with intermittent grounds, a smaller resistor may be used if the readings are erratic. To install thii resistor the wire at R5 must first be removed. After R5 has been removed push the resistor ends through thc holes for R5 (from the terminal side) until the resistor lies flat with the panel surface. On the back side. solder the wites to the holes. Then ciip off the extra wire with pliers. The auxiliary component arca in question will now look like Figure 15. This connection does not require any additional traces to be cut. f p 1s. GIUd roop Conwtioa -

DlGiTAL Inrtdhg D i g M M d e s - AUX'LIARY Modules are available to safely connect the digital VO lines to high

'CoMPONENTS voltage AC and DC sources. There are four basic types: . . .

AC output: to switch AC power (relay) DC output: to switch DC power (relay) ACínpur: Lo sense AC voitage DCinpul, Lo sense DC vofrage

The output types are used to switch loa& on and off. i h e input types are used to sense the higMow status of a signal. Ail of the modules provide optical isolation between the high voltage and terminations. These modules may be installed on any DAThhuttfc. You may have had modules installed at the factoty. If not, you may do the installation yourself. First, remove the jumpen labeled R6 and R7. This disconnects the digital VOS from the terminals. The module will not fit into the panel until these jumpers are removed. Then, simply insert the module and fasten the retention screw. The terminals for that VO have now changed their function from low voltage VO to high voltage isolated VO. The two terminals become one input channel (high and low lines), or one output channel (like relay contacts), depending on the type of module you have installed.

CAUnON When using these terminals as input lines, be sure to connect the positive line to the old OUT terminal and the negative line to the old IN terminal. Failure to do this will result in the module not switching.

Inrtdhg Pd-up Rcslrtors - As noted in the Appfications ReJerence Manual and previously in this manual, the digital outputs are open collector and must have a power source connected in order to dnve loads. Merely connect- ing the output terminal through a load (such as a bulb) and then to digital ground will not work. In this case, a pull-up resistor con- necting the output terminal to a power supply will complete the circuit. This pull-up resistor is installed in position R8, as shown in Figure 6(b), which connects the output to the unitk +5 volt power supply.

Figures 2 and 3 in Chapter 1 show the physical location of R8 on the DATAshutdc. Note that R8 may have to be installed manually between the +5 volt supply and the output terminal in question. To install this resistor, push the resistor ends through the holes for R8 (from the terminal side) until the resistor lies flat with the panel surface. On the back side, solder the wires to the holes. Clip off the extra wire with pliers. This connection does not require any additional traces to be cut.

Inrtdhg cmrmt Mhg Rerirtors - To limit the current in the digital input line, install a resistor in the R6 position (remove the corresponding jumper fint).

Insta11 a resistor in the R7 position (after removing the jumper) tc limit the current in the digital output line.

The DATAshuttlc features one 16 bit counteritimer that may be used to count up to 216 (65,535) events. The maximum rate of pulses i t can measure is 3MHz. The counter/timer is connected to an interna1 2MHz clock, allowing it 0.5j.15 resolution. Then are four dedicated terminals for the counter/timer: Comitcr/rn#n L e s ava7de on he UAlAshunle -

Troubles hoo ting: Ins tallation

if you experience difficulty in getting your DATAshuttlc up and mnning, the descriptions in Chapter 1. If the software repons a unit failure, or that it cannot find a DATAshuttlc, then try these remedies: 1. Make IuIc Ibe calde is semely connected from the DATAshuttlc

input connector to the parallel port on the computer. 2. Moke sure he UATAshuffíe is connected to a poww some, either an

AC Adapter or Keyboard Adapter. A red light on the board will indicate that power is present.

3. Verify rhd fbe software ir up to drite (a version compatible with the unit you are using). Contact us, or your software provider.

4. Discmnecí additioml UAlAshuffles and printers in your setup. 5. Conned rhe DATAshuffle ro morher pmallel port. 6. R emove any cid&riod datu acquisition cards from the computer. 7. If possibk, insfall rhe DAlAshuflle witlr morher compufer to veriíj its

your system's AUTOEXEC.BAT file, temporanly. Also REM out any AUTOEXECBAT and CONFIG.SYS lines that relate to a PCMCIA port, such as device drivers, as these have been known to cause conflicts.

9. Mde sure hui yw pbg fhe DATAshvttle in md tlkt poww ir cmtedeif before staning your computer. Many laptops will deactivate the parallel port at the stan-up if nothing is attached to it.

10. Make sm fbot the Print Manqlerh not #tive in itrC W i w s rnVr ronmCnt when attempting to start the DATAshuttlc. Some com- puters automatically load the Print Manager at stanup, and it can interfere with WorkBench PCfor Windows' ability to com- municate with the hardware. Printing is posible while using the DATAshuttlc but not during the initial loading of the Work- Bench PCfor Windows software.

Troubleshooting: Operation

HINTS It's essential to have exactly one ground reference per channel. This single connection to ground makes sure you don? urceed the common mode range of input. (More than one connection per channel can lead to ground loops, causing errors or erratic readings. Connecting the - to the Com terminal provides a single ground. Your sensor might aiso pro- vide another ground. If you're not sure that your sensor is grounded, try connecting the - to Com. and not, and see which works best.) Remember that if speed is not critical, selecting the "low noise mode" in software always provides the best accuracy and resolu- tion with your data acquisition unit.

OPERATING Here are rnini "case studies" of difficulties, along with some easy Qs AND As solutions:

hb/em: My cmit r d s d o g inpirtr wrung. Adion: Make sure the calibration numbers in the non-volatile

memory are non-zero (run EDITCAL to check this). If the figures are correct, try shoning + to - to Com: the unit should return a reading around OV

1.5 volts by leakagc from the U7407 chips. This is enough to read logic high. You can pul1 them low with a 470 ohm resistor to ground.

Does not include the accuracy of the thermocouple itself (cold junction error must be added in; cold junction compensation with DATAshuttlc-TG only). Resolution assumes 12 bit nsolution in use for DATAshuttlt-12, 16 bit resolution for DATAshuttlt-16; it is approximate as resolution varies with temperature measured. Thermocouples use the 50 rnV range. For inputs below -5 mV (below approximately -100 degrees C). use the +A25 rnV range.
