Page 7: Preface
About this User’s Guide What you will learn from this user’s guide This user’s guide explains how to install, configure, and use the CIO-EXP16 so that you get the most out of its analog input and digital I/O features. This user’s guide also refers you to related documents available on our web site, and to technical support resources. -
Page 8: Introducing The Cio-Exp16
You can power the CIO-EXP16 internally from the A/D board, or externally from the computer's +5 V power supply connectors. The CIO-EXP16 board is mounted externally to the PC. It can be placed in the open on a benchtop or in a case. Software features For information on the features of InstaCal and the other software included with your CIO-EXP16, refer to the Quick Start Guide that shipped with your device. -
Page 9: Installing The Cio-Exp16
In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of the software you received with your CIO-EXP16 and information regarding installation of that software. Please read this booklet completely before installing any software or hardware. -
Page 10: Unpacking The Cio-Exp16
Connecting to the A/D board There are two 37-pin D type connectors on the CIO-EXP16 — P1 and P2. They are wired 1:1. Connector P1 is labeled , and is provided to daisy chain additional CIO-EXP16 boards. Use a C37FF-x cable to daisy NEXT EXP chain the CIO-EXP16 boards together. -

DAS16 position. Connection to a DAS16 series board requires a special 37-conductor cable (C-EXP2DAS16-10) since the pin relationship of the CIO-EXP16 and DAS16 signals is not 1:1. Refer to the C-EXP2DAS16-10 cable pin out table below. C-EXP2DAS16-10 cable pin out... -

Connections (available at www.mccdaq.com/signals/signals.pdf). Configuring the CIO-EXP16 Before using the CIO-EXP16, there are switches and jumpers to set, and one or more cables to install. Please turn the PC power OFF before proceeding. The CIO-EXP16 is shipped with the factory-default settings listed in the following table. -

Figure 3. Switch, jumper, and connector locations Before using the CIO-EXP16, verify that the board is configured with the settings that you want. Review the following information to change the default configuration of a jumper, switch, or solder gap. - Page 14 CIO-EXP16 User's Guide Installing the CIO-EXP16 External +5 V PC power connections You can power the CIO-EXP16 with your computer’s +5V power supply using the optional C-PCPOWER-10 ® cord. Each end of the cable has a keyed Molex type connector. To connect to your computer’s power connectors, do the following: Turn off power to the computer and remove the cover.

MUX board’s output(s). Each CIO-EXP16 output, if used, must be exclusively assigned to an A/D channel using these jumpers. In other words, for all CIO-EXP16 boards attached to an A/D board, only one jumper on any of the jumper blocks should be assigned to a particular channel. -
Page 16: Exp Gain
(refer to the hardware user's manual supplied with your A/D board for more information). You can connect up to eight banks of 16 CIO-EXP16 inputs to a DAS08 series board, for a total of 128 inputs. Channel selection for the DAS16 family The CIO-EXP16 jumper positions 0-7 and 8-15 can be used with the CIO-DAS16. -
Page 17: Configuring The A/D Board
If the range on your A/D board is fully programmable, the software you use for temperature measurement will determine the correct range to use. Calibrating the CIO-EXP16 You should calibrate the CIO-EXP16 after you first connect to a A/D board, if you change the gain setting of the input amplifier, and at 6 month intervals. -
Page 18: Chapter 3 Functional Details
Functional Details CIO-EXP16 inputs The CIO-EXP16 inputs are screw terminals which will accept 12-22 AWG wire. Each channel has a screw terminal for signal high, signal low and ground. The inputs are differential, which require three connections from the signal source to the CIO-EXP16 — Signal High, Signal Low, and Signal Ground. -
Page 19: Thermocouples
A floating differential input has two wires from the signal source, and a 100 K ground reference resistor installed at the CIO-EXP16 input. The two signals from the signal source are Signal High (CH#-HI) and Signal Low (CH#-LO). The reference resistor is connected between the CH#-LO and #-G (Signal Ground) pins. -
Page 20: Cold Junction Compensation
Ground reference The CIO-EXP16 inputs are fully differential, which help reject noise on thermocouple wires. Close the ‘G’ pad thermocouples to work properly. The 'G' pad provides a reference from ground to the analog low input via a 100 K resistor. - Page 21 350°C 244°C 152°C 98°C 1035°C 697°C 1445°C 961°C 658°C To read the maximum usable temperature for type K and E thermocouples, set the gain to or less. After you change the gain setting, calibrate the CIO-EXP16 using the InstaCal utility.
