Measurement Computing CIO-EXP-GP - Manual (Page 5)

1 INTRODUCTION
The CIO-EXP-GP is an eight-channel, signal conditioning accessory designed for use with the DAS08
and DAS16 family of data acquisition boards. It can condition signals from bridge sensors, RTDs or
thermocouples on a per-channel basis. It converts the sensor's output to a voltage suitable for conversion
by a DAS08/DAS16 or other analog to digital conversion board.
This manual is organized into sections that explain the CIO-EXP-GP on a sensor by sensor basis. The
CIO-EXP-GP is complex, and the information on bridge sensors may confuse those interested in RTDs
only, and vice-versa. Here are the sections of this manual:
Software Installation All users should review this section regardless of the
application.
General Configuration: All users should review this section regardless of the
application.
Configuration for Voltage Measurement: Users interested in voltage measurement applications
should review this section.
Configuration for Thermocouples Users interested in temperature measurement
applications using thermocouples should review this
section.
Configuration for RTD Measurement Users interested in temperature measurement
applications using RTDs should review this section.
Configuration for Resistance Measurement: Users interested in resistance or strain gauge
measurement applications should review this section.
Please carefully read the installation and general configuration sections, and each of the sections
pertaining to the sensors you intend to use. There are optional resistors, jumpers, switches, and other
connections to be made on the CIO-EXP-GP. Failure to set up the channels correctly for the sensor in
use will result in inaccurate or invalid measurements.
2 SOFTWARE INSTALLATION
Software is not included with the CIO-EXP-GP, but each of the data acquisition boards with which it is
intended to be used includes software called InstaCal™ that may be used to aid installation, verify
operation and perform calibration of the CIO-EXP-GP. The disk or CD labeled InstaCal contains this
software package. If you ordered the Universal Library™, you should load InstaCal from that CD or
disk set.
The board has a variety of switches and jumpers to set before installing the board in your computer.
InstaCal will show you all available options, how to configure the various switches and jumpers to match
your application requirements, and will create a configuration file that your application software (and the
Universal Library) will refer to so the software you use will automatically have access to the exact
configuration of the board.
Please refer to the Software Installation Manual regarding the installation and operation of InstaCal. Use
InstaCal along with the following hard copy information to set the hardware configuration of the board.
