Chapter 1

Introducing the PCI-DAS-TC
Overview: PCI-DAS-TC features
The PCI-DAS-TC is a 16-channel thermocouple/voltage input board for the PCI bus. The board accepts sevendifferent types of thermocouple input, J, K, E, T, R, S, and B. Its digital output is scaled for temperature ineither ºC or ºF. An onboard microprocessor handles all the control and math functions, including: CJC (ColdJunction Compensation), automatic gain and offset calibration, scaling (voltage to temperature translation) andthermocouple linearization. This relieves the computer from performing all these functions. The analog input
section is electrically isolated from the computer.
The PCI-DAS-TC is designed for use with the CIO-STA-TC adapter board. The CIO-STA-TC is an externalscrew terminal board for thermocouple connections. This adapter board provides screw terminals for eachthermocouple input channel on the PCI-DAS-TC. A cold junction compensation (CJC) sensor is integrated into
an isothermal bar to maintain the screw terminals at a constant temperature. You can configure open
thermocouple detection (OTD) for each input channel with on-board switches. The CIO-STA-TC screw
terminal board is mounted in an enclosure to minimize errors caused by local currents or air drafts.
The PCI-DAS-TC board is shipped fully-calibrated from the factory, with calibration coefficients stored in
nonvolatile RAM. At run-time, these calibration factors are loaded into system memory and automatically
retrieved each time a different range is specified.
The PCI-DAS-TC is available by itself (MCC part number PCI-DAS-TC/BRD), or as part of a kit that includes
the CIO-STA-TC screw terminal adapter board and a five foot shielded cable. The MCC part number for the kit
is PCI-DAS-TC.

Functional Details

CIO-STA-TC screw terminal adapter board
The CIO-STA-TC is a specially configured screw terminal adapter board designed specifically for use with the
PCI-DAS-TC. The board has screw terminals for each thermocouple channel, a cold junction sensor integrated
into an isothermal bar, and the option of installing an "open thermocouple detection" circuit.
Each thermocouple input is made through two screw terminals — one positive (+) and one negative (-). Connect
the thermocouple wires to the appropriate terminals, connect the CIO-STA-TC to the PCI-DAS-TC, and yourboard is ready for use.
Note the polarity when connecting the thermocouples
Be careful to observe correct polarity when connecting thermocouple wires or extension wires.
The CIO-STA-TC is available by itself (MCC part number CIO-STA-TC), or as part of a kit that includes the
PCI-DAS-TC board and five foot shielded cable.

Open thermocouple detection
The only user configurable option in the CIO-STA-TC is the open thermocouple detection resistors. These are aseries of 20 MΩ resistors that can be connected between the + terminal of the thermocouple and a known
voltage that is larger than any allowable thermocouple output.
The 20 MΩ resistors are large enough so that they do not affect the readings from the thermocouples. If athermocouple junction should open, a 20 MΩ will drive the input voltage high enough so the software canrecognize that it is not a valid thermocouple reading.
Open thermocouple detection circuitry is set via dip switches on the CIO-STA-TC. DIP switches are labeled,and each channel has a switch. To enable open thermocouple detection for a channel, set the switch to ON (up,towards the isothermal block). To disable the function, set the switch to OFF (down, towards the outside of theboard).

PCI-DAS-TC User's Guide

Functional Details

During normal operation, the V-F converts the CJC input, calibrates the gain at a Gain = 1 using the 9.9 V
input, offset using the ground input, and measures the thermocouple or voltage depending on the input type. The
CJC and the gain/offset values are stored in an onboard RAM for cold junction scaling and calibration. These
parameters are sampled continuously. Refer to the block diagram shown in Figure 3 on page 12.
The V-F converter is an Analog Devices AD652 SVFC (Synchronous V-F Converter) which offers full scalefrequency up to 2 MHz and extremely low linearity error. The 4 MHz clock for the V/F converter is supplied by
TIMER1 and passes through opto-isolation. The output of the V/F converter, passing back through optoisolation, is supplied to TIMER0. TIMER0 is gated on by TIMER2 for a period dependent upon the specified
conversion frequency of 50Hz, 60Hz or 400Hz. At the end of the sampling period, the count in TIMER0
represents the voltage input. In general, the longer the count time, the higher the resolution and better the noise
reduction, unless in the case of periodic noise where the periodic frequency (for example, 50, 60, and 400 Hz) ismore effective in reducing the noise.

Processing and control
This section consists of control and decode logic, a microcontroller and local memory to perform channel
scanning, CJC measurements, calibration, linearization, averaging, and voltage/temperature translation. The
above parameters are set up from a configuration file which is downloaded by the PC to the microcontroller’s
local memory through the Dual Port RAM. After the microcontroller is given the command to start conversions,these parameters are set on a channel-by-channel basis with data reported to the PC in the format specified by
the configuration file. For thermocouple inputs, the microcontroller reads the counter, adjusts the data based on
the CJC value and gain/offset calibration, then linearizes and converts the reading to the appropriate
temperature units.
To perform linearization, the microcontroller gets the raw frequency count from TIMER0, translates that into
bits, factors in the CJC correction and gain/offset calibration, then refers to a previously stored lookup table
stored in ROM. There is a separate table for each thermocouple. The lookup tables are a method to optimize thelinearization by using more reference points along areas of greatest temperature/voltage change instead of using
mathematical translation, which requires lengthy polynomial manipulation. Using lookup tables requires finding
two consecutive points, one greater and one less than the measured value, then interpolating the measured
temperature value.

Process flow
The PC itself performs very few functions for the PCI-DAS-TC. The driver software (included with the PCIDAS-TC kit) sets up individual channels, including the thermocouple type, CJC on/off, voltage or thermocouple
gain, channel, and temperature units. The sample rate and sample averaging configuration are also set by thedriver for all channels. Both during initialization and when the configuration changes, this information is passed
to the CPU through the Dual Port RAM and stored for the specified channel. The PC then notifies the CPU tostart taking measurements. When the CPU completes a conversion, an interrupt is generated so that the PC
reads the data from the Dual Port RAM which the CPU had written to. The 32-bit floating point data is stored infour consecutive locations in the Dual Port RAM. Refer to the "Dual Port RAM Memory Map" section in theRegister Map for the PCI-DAS-TC for more details on this process. This document is available on our web siteat www.mccdaq.com/registermaps/RegMapPCI-DAS-TC.pdf.
The on-board CPU has a much more complicated task. The CPU must set all the parameters for conversion of
the selected channel. After conversion, it must get the data, adjust it based on the stored CJC measurement,
calibrate against gain/offset error, linearize it based on lookup tables for each associated thermocouple type, andreport the data to the PC through the Dual Port RAM. During this process, the CPU goes to the next channeland sets up the parameters for that channel to allow sufficient settling time before the next conversion begins.
