1.0 INTRODUCTION

Thank you for purchasing a CIO-DAS-TC or PCI-DAS-TC. These boards represent the latest
technology and are easy to use, powerful and extremely accurate. The DAS-TC includes the CIO-STA-TC, a screw
terminal board with an isothermal block and CJC sensor, as well as a C37FFS-5 five-foot shielded cable.

The CIO-DAS-TC and PCI-DAS-TC are 16-channel thermocouple/voltage input boards for the ISA and PCI bus,
respectively. The DAS-TC boards accept seven different types of thermocouple input (J, K, E, T, R, S, and B), and
provide the user with a temperature in either degrees C or F. An onboard microprocessor handles all the control and
math functions including; CJC (Cold Junction Compensation), automatic gain and offset calibration, and thermocou­ple linearizati on, thus off-loading the computer CPU from performing these functions. The analog input section is
fully isolated from the computer. A block diagram of the DAS-TC is shown on the following page.

The CIO-DAS-TC and PCI-DAS-TC are similar in all respects except two: first, the CIO-DAS-TC is designed to
work with the ISA bus and the PCI-DAS-TC with the PCI bus. Second, the CIO-DAS-TC has an onboard dip switch
for setting the base address; while the PCI-DAS-TC is completely plug-and-play, with no jumpers or switches to set!
For the sake of clarity in this manual, we will refer to both boards collectively as DAS-TC, except where these two
differences apply.

The DAS-TC is supported by the powerful Universal Library driver package. The boards are also
supported by many third-party, high-level data acquisition software.

2.0 INSTALLATION

The installation routine varies only slightly depending upon whether you are installing the CIO-DAS-TC or the

TM

PCI-DAS-TC board. The CIO-DAS-TC r equire s that you run the included Insta

program, then verifying and,

Cal

if necessary, changing t he base addr ess using an onboar d dip switc h before pl ugging the board in. If you ar e install ­ing the PCI-DAS-TC, you need only plug it in. The base address is allocated by the PCI plug & play procedure.

2.1 SOFTWARE INSTALLATION

2.1.1 WINDOWS 95, 98, NT AND ABOVE

If you will be using the Universal Library with your board, insert the Universal Library diskette or CD in an appro­priate drive run the program SETUP.EXE, and follow the installation instructions provided. This program will install
both Insta
98, you will have the option of installing the 16-bit and/or 32-bit library. Unless you have a specific reason to use the
16-bit library (e.g. compatibility with an existing program) install the 32-bit version. Please note that the DAS-TC
boards are not currently supported by the 16-bit library and so are not currently compatible with the DOS or
Windows 3.x operating systems. Please contact the factory if you require 16-bit library support.

If you are not using the Universal Library, insert the disk or CD labeled Insta
run SETUP.EXE. The install wizard will now launch and you will then be prompted for additional information.
Follow the instructions and, if possible, accept the defaults, especially if this is your first installation. It will be easier
for us to assist you in the unlikely event of trouble during your system setup and operation.

2.1.2 UNIVERSAL LIBRARY INSTALLATION OPTIONS

The Universal Library p rovides example programs for a wide variety of programmi ng la nguages. If you are installing
the Universal Library, an "Installation Options" dialog box will allow you to select which languages' example
programs are loaded onto your computer. Select the desired example programs by checking the appropriate box(s).

into an appropriate drive, and

2.1.3 FILE DEFAULT LOCATION

InstaCal will place all appropriate files in "C:CB" If you change this default location remember where the installed
files are placed as you may need to access them later.

2.1.4 INSTALLATION QUESTIONS

At the end of the installation process the installation wizard will ask a series of questions updating your startup files.
Unless you have knowledge to the contrary, simply accept the default (YES) when prompted. You will also be asked
if you would like to read an updated README file. If possible, please choose yes and take a look at the information
in the file. It will include the latest information regarding the software you are installing.

2.1.5 INSTALLATION COMPLETION

After the installation of InstaCal is complete you should restart your computer to take advantage of changes made to
the system.

2.1.6 DOS AND WINDOWS 3.x

Most users are now installing PCI Bus boards in systems with 32-bit operating syste ms (e.g., Windows 95, 98 or
NT). The DAS-TC is not currently supported by the 16-bit library required to run under DOS or Windows 3.x.

Please contact us if your application is running under DOS or Windows 3.x.

2.2 CIO-DAS-TC HARDWARE INSTALLATION

2.2.1 SETTING THE BASE ADDRESS SWITCH

Prior to installing the CIO-DAS-TC board, you need to set the base address by using the dip switch located on the
board. The easiest way to set the base address switch is to let InstaCAL show you the correct settings. This process is
described in the section (2.2.2).

However, if are already familiar with setting ISA base addresses, you may use the base address switch description
below to guide your base address selection.

Unless there is already another board in your system using address 300 HEX (768 Decimal), you can leave the
switches as they are set at the factory. The example shown in the following diagram shows the settings for the factory
default base address of 300H.

A complete address is constructed by calculating the HEX or decimal number which corresponds to all the address
bits the CIO-DAS-TC has been instructed to respond to. In the default configuration, shown above, addresses 9 and
8 are DOWN, and all others are UP. Address 9 = 200H (512D) and address 8 = 100H (256D), when added together
they equal 300H (768D).

NOTE

DO NOT PAY ATTENTION TO THE NUMBERS PRINTED ON THE SWITCH. PLEASE REFER
TO THE NUMBERS PRINTED IN WHITE ON THE PRINTED CIRCUIT BOARD!

The InstaCAL software package will also help you set the base address switch. If you have questions regarding the
following diagram, run InstaCAL, and follow the instructions provided.

2.2.2 RUN InstaCAL
InstaCal

To run

2.2.3 PLUG IN THE CIO-DAS-TC BOARD

Once you are done selecting and verifying the base address, you may shut the computer off and open the case.

Locate an empty ISA expansion slot in your computer. Push the board firmly down into the expansion bus
connector. If it is not seated fully it may fail to work and could short circuit the PC bus power onto a PC bus signal.
This could damage the motherboard in your PC as well as the DAS-TC. We also highly recommend that you use the
screw provided on your computer's back plate to secure the DAS-TC in it's location.

Replace the cover to the computer and turn it on. Plug one end of the cable provided into the DAS-TC board, and the
other into the CIO-STA-TC. Your hardware is now installed.

2.2.4 RUN InstaCAL AGAIN

Run the InstaCal progr am in order to test your bo ard and co nfigure it for run-time use. By confi guring the boar d,
you add information to the configuration file, cb.cfg, that is used by the Universal Library and other third-party data
acquisition packages that use the Universal Library to access the board.

Check that the CIO-DAS-TC is still listed as an installed board. Then proceed to the " Calibrate" or "T est" functions
of InstaCAL to assure that your board is functioning properly. Once the board has been tested, select FILE then
Exit, and the configuration file will be written to your hard disk.

2.3 PCI-DAS-TC HARDWARE INSTALLATION

2.3.1 PHYSICAL INSTALLATION

The PCI-DAS-TC is completely plug and play. Simply follow the steps shown below to install your PCI hardware.

1.

Turn your computer off, unplug it, open it up and insert the PCI board into any available PCI slot.

2.

Close your computer up, plug it back in and turn it on. Plug one end of the cable provided into the DAS-TC
board, and the other into the CIO-STA-TC. Your hardware is now installed. Run InstaCal
may use one of the built-in test functions to assure the board is operating properly

3.

Windows will automatically detect the board as it starts up. If the board's configuration file is already on the
system, it will load without user interaction. If the configuration file is not detected, you will be prompted to
insert the disk containing it. The required file is on the InstaCal or Universal Library disk you received with
your board. Simply insert the CD (or Disk 1 if your software is on floppy disk) into an appropriate drive and
click on CONTINUE. The appropriate file should then be automatically loaded and the PCI board will
appear in the Device Manager under DAS Component.

2.3.2 RUN InstaCAL

Run the InstaCal progr am in order to test your bo ard and co nfigure it for run-time use. By confi guring the boar d,
you add information to the configuration file, cb.cfg, that is used by the Universal Library and other third-party data
acquisition packages that use the Universal Library to access the board.

Launch InstaCal by going to your Start Menu then to Programs, then to ComputerBoards, and finally choosing Insta-
Cal. You may also launch the program by going to START >RUN and typing INSCAL32, or by finding the file
named "inscal32.exe" in your installation directory and double clicking it.

InstaCal will display a dialog box indicating the boards that have been detected in the system. If there are no other
boards currently installed by InstaCal, then the PCI-DAS-TC board will be assigned board number 0. Otherwise it
will be assigned the next available board number.

TM

again and you

You can now view and change the board configuration by clicking the properties icon or selecting the
Install>Configure menu.
