Overview and Theory of Operation 1 Features and General Information …… 1-1 Scanning…… 1-5 Triggering …… 1-6 Theory of Operation …… 1-7 Features and General Information DaqTemps are reliable, accurate, and compact data acquisition solutions that evolved from a primary focus on thermocouple applications. There are presently four DaqTemp systems. Each includes the following hardware and software.
Thermocouple Channels (CH1 - CH7, CH9 - CH15) Each DaqTemp features on-board cold junction compensation (CJC) for direct measurement of type J, K, T, E, N28, N14, S, R, and B thermocouples. The following table provides the temperature range for each of these thermocouple types.
Differential Input Channels (1H / 1L - 7H / 7L) Each DaqTemp model has seven differential input channels for measuring voltage. The voltage channels are labeled from 1H / 1L to 7H / 7L, with the “H” and “L” representing channel high and channel low. The seven channels are located on the Analog I/O portion of the card. Each differential input channel also has a current shunt resistor that can be user-installed.
24-Bit, General Purpose Digital I/O (Channels A0 - A7, B0 - B7, and C0 - C7) All DaqTemps have 24-bit, general purpose, digital I/O that can be used to directly control and monitor 24 digital I/O lines. The 24-bit digital I/O is divided into three 8-bit ports, which are labeled: A0-A7, B0-B7, and C0-C7. Each port can be programmed as an 8-bit group for either input or output.
Scanning Every DaqTemp has an on-board scan sequencer that permits the user to select any combination of up to 512 channel/range combinations. The sequencer scans all channels contained in the sequence at the rate of 5 µs/channel, thereby minimizing the time-skew from channel-to-channel. The user can also set the time between scan groups, from 0 to 6 hours. In addition to scanning analog inputs, the sequencer can scan digital inputs and counter inputs.
Triggering Triggering can be the most critical aspect of acquiring data. The DaqTemp PCI Board supports a full complement of trigger modes to accommodate a wide variety of applications. Hardware Analog Triggering. Many data acquisition products claim analog triggering, but rely on the PC to take readings and make a decision, which leads to uncertain and potentially long latencies.
• Variable pre-trigger with post trigger stop event (driver support only). Unlike the previous pretrigger modes, this mode does not have to satisfy the pre-trigger number of readings before recognizing the trigger event. Thus the number of pre-trigger readings acquired is variable and dependent on the time of the trigger event relative to the start. In this mode, data continues to be acquired until the stop trigger event is detected.
Analog Input Channels The DaqTemp Series PCI Boards allow analog input configuration for the voltage input channels and the thermocouple input channels. Channel Selection and Mode Settings The DaqTemp module accepts up to 7 differential inputs. Channel Range and Polarity Each of the seven differential voltage input channels may be programmed for either unipolar or bipolar mode with gain settings of 1, 2, 4, 8, 16, 32 or 64.
Output Channel Configuration Analog Output Channels Each D/A channel can be configured for waveform output individually. If the D/A channel is not configured for waveform output, it then is available for asynchronous output operations. Synchronous Output Clocking The DaqTemp Series PCI Boards allow clocking of the synchronized output by the acquisition clock source, an internal, programmable pacer clock or by an external clock source.

DaqTemp7 and DaqTemp14 have no DACs.
Each DaqTemp makes use of one high-speed, multi-function, PCI plug-and-play data acquisition board. The PCI board features a 16-bit, 200-kHz A/D converter (ADC), digital calibration, bus mastering DMA, 24 digital I/O lines, four counters, and two timers. In addition, the DaqTemp7A has two16-bit 100 kHz D/A converters (DACs); and the DaqTemp14A has four DACs. DaqTemp modules provide access to all of the system’s input and output signals.

How to Install DaqTemp 2 Step 1 – Install Software …… 2-2 Step 2 – Install the DaqTemp PCI Board …… 2-2 Step 3 – Configure the PCI Board ….. 2-4 Step 4 – Test the PCI Board ….. 2-5 Step 5 – Connect the DaqTemp Module to its associated PCI Board …… 2-6 Note: You should keep your DaqTemp serial numbers and your DaqView/2000 authorization code (if applicable) with this document. Space is provided below. The PCI board serial number is located on its 100-pin P4 connector.
Step 1 – Install Software IMPORTANT: Software must be installed before installing hardware. 1. Remove previous version Daq drivers, if present. You can do this through Microsoft’s Add/Remove Programs feature. 2. Place the Data Acquisition CD into the CD-ROM drive. Wait for PC to auto-run the CD. This may take a few moments, depending on your PC. If the CD does not auto-run, use the Desktop’s Start/Run/Browse feature. 3. After the intro-screen appears, follow the screen prompts.
5. On the PC’s rear panel, loosen and remove the screw for the blank adapter plate that corresponds with the chosen PCI bus. See the following figure. Removing a Blank Adapter Plate from the Host Computer’s Rear Panel (Steps 5 and 6) 6. Remove the adapter plate. Refer to your PC Owner’s Manual if needed. 7. Align groove in the DaqTemp PCI board’s edge-connector with the ridge of the desired PCI slot, and with the corresponding rear-panel slot on the PC. See following figure.
Step 3 – Configure the DaqTemp PCI Board DaqTemp PCI boards have no jumpers or switches to set. Configuration is performed, in its entirety, through software. Refer to the following figure and steps to complete the configuration. 1. Run the Daq Configuration control panel applet. Navigation from the desktop to the applet is as follows: Start ⇒ Settings ⇒ Control Panel ⇒ Daq*Configuration (double-click). 2. Double-click on the Device Inventory’s DaqTemp icon. The DaqTemp Properties tab will appear.
Using “Add Device” This method is for users who have accessed the Daq Configuration control panel applet, but have no DaqTemp icon. (A) After accessing the Daq Configuration control panel applet, click on the Add Device button (see figure, right). The Select Device Type window will appear. (B) Using the Device Type’s pull-down list, select the applicable board. In the example at the right DaqTemp7 is selected. (C) Click the OK button. The DaqTemp Properties tab will appear.
Step 5 – Connect the DaqTemp Module to its PCI Board Connecting the DaqTemp Module to the PCI Board CAUTION Turn off power to and unplug the host PC prior to connecting the DaqTemp to the computer. Failure to do so could possible result in equipment damage. Prior to mating the CA-195 cable’s P4 connectors to the PCI board and the DaqTemp, be sure to align the P4 orientation indicators (▲ ▲) of the connectors that are being mated. Connect the DaqTemp module to its PC-based PCI board as follows. 1.
Making Signal Connections 3 Connect the signal lines to the intended terminals on DaqTemp’s card-mounted terminal blocks for Digital or Analog I/O, and/or to the chassis-mounted terminal blocks for thermocouple connections. In regard to thermocouples … • DaqTemp7 and DaqTemp7A provide input connections for channels 1 through 7. • DaqTemp14 and DaqTemp14A provide input connections for channels 1 through 7 and for channels 9 through 15.
For isothermal performance, an exposed, grounded copper plane surrounds the input connectors. It is important that non-insulated input wires do not contact the grounded plane − since such contact can degrade measurement integrity. It should be noted that thermocouples output very small voltages and that long thermocouple leads can pickup a large amount of noise. However, the DaqTemp modules inherently provide a high level of noise immunity via their 4 Hz signal bandwidth and input filtering.
Software for DaqTemp Applications 4 DaqView, Channel Setup Tab Selected DaqTemp devices are intended for use with two categories of software: (1) Ready-to-use graphical programs, also referred to as out-of-the-box programs. These include DaqView, DaqViewXL, eZ-PostView, eZ-TimeView, ands eZ-FrequencyView. (2) Icon-driven software. This category includes DASYLab and LabView and their associated thirdparty drivers.

Electric shock or damage to equipment can result even under low-voltage conditions. Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.) Use care to avoid touching board surfaces and onboard components. Only handle boards by their edges (or ORBs, if applicable).
Install the DaqTemp PCI Board with its CE ORB If you are installing the DaqTemp Series Board for the first time, refer to chapter 2 of this manual, How to Install DaqTemp. 1. If you have not already done so, turn off power to, and UNPLUG the host PC and externally connected equipment. Then remove the PC’s cover. Refer to your PC Owner’s Manual as needed. 2. Install the DaqTemp Series PCI Board [with CE ORB] as follows (see following figure).
Connect the CA-195CE Cable to the Board DaqTemp Module 1. Connect one end of the CA-195CE Cable to DaqBoard/2000 Series Board’s P4 connector. Note that either end of the cable can be connected to the board; however, the white locator triangles must align with each other. 2. Align the Cable Clamp (1033-2009) with the CE ORB and secure the items with two 4-40 x 3/16 screws (provided). DaqTemp PCI Board Note: In the right hand figure, the cable is not shown to allow for greater clarity of parts.
Connect Cable and Grounding Pigtail to the DaqTemp Module 1. Verify that the P4 connectors of the CA-195CE Cable and the DaqTemp Module are correctly aligned. Correct alignment is indicated when the P4 locator triangles face each other (see figure). The triangles locate pin A1. 2. Complete the connection. 3. Connect the open end of the Grounding Pigtail to the threaded insert located to the right of DaqTemp’s P4 connector. See following figure.
Calibration 6 Overview …… 6-1 Using DaqCal.exe …… 6-1 Overview DaqTemp PCI Boards are digitally calibrated at the factory. The digital method involves storing a correction factor for each range [on the DaqTemp PCI Board] at the time of calibration. Whenever a particular range is selected, the appropriate calibration constant is automatically applied to a compensating DAC, thereby calibrating the specific range.
Reference Note: If the ambient temperature of the operating environment is below 18°C or above 28°C, or if the DaqTemp is near or outside its one-year calibration interval, then the absolute accuracy may be improved through the use of an external temperature calibrator. Refer to the document, System Calibration and Unit Conversion Using mx + b, p/n 457-0949 for detailed information. A PDF version of the document is included on your data acquisition CD.
