Chapter 1

Introducing the CIO-DAS08/JR
Overview: CIO-DAS08/JR features
The CIO-DAS08/JR provides eight channels of 12-bit analog input at a fixed ±5V range.
The board also provides eight digital inputs and eight digital outputs for sensing and controlling digital devices.
The digital bits are port-addressable, and are dedicated to either input or output. All digital bits are TTL level.
The CIO-DAS08/JR can be upgraded to a CIO-DAS08/JR-AO by purchasing and installing the CIO-DUALDAC.

Software features
For information on the features of InstaCal and the other software included with your CIO-DAS08/JR, refer tothe Quick Start Guide that shipped with your device.

Installing the CIO-DAS08/JR

Unpacking the CIO-DAS08/JR
As with any electronic device, you should take care while handling to avoid damage from staticelectricity. Before removing the CIO-DAS08/JR from its packaging, ground yourself using a wrist strap or bysimply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately byphone, fax, or e-mail:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.
Fax: 508-946-9500 to the attention of Tech Support
Email: techsupport@mccdaq.com

Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-SoftwareQuick-Start.pdf.

Configuring the CIO-DAS08/JR
Before you install the CIO-DAS08/JR in your computer, you must set the base address by using the dip switch
labeled ADDRESS located on the board. By default, this address is set to 300 h (768 decimal). The easiest way
to set the base address switch is to let InstaCal show you the correct settings. However, if are already familiar
with setting ISA base addresses, you may use the base address switch description below to guide your baseaddress selection. The example shown in Figure 1 shows the settings for the factory-default base address of 300hex.

9 8 7 6 5 4 3SWA9A8A7A6A5A4A3HEX
200
1008040201008

Figure 1. Base address switches

The address logic works by adding up the weights of individual switches to make up a base address. In thedefault configuration shown in Figure 1, addresses 9 and 8 are DOWN, and all others are UP.
Address 9 = 200 hex (512 decimal) and address 8 = 100 hex (256 decimal); when added together they equal
300 hex (768 decimal).
Disregard the numbers printed on the switch
When setting the base address, refer to the numbers printed in white on the printed circuit board.

Installing the CIO-DAS08/JR
After you configure the board's switches and jumpers, you can install the CIO-DAS08/JR into your computer.
To install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install
the MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on
installing the software.
1.

Turn your computer off, open it up, and insert your board into an available ISA slot.

2.

Close your computer and turn it on.

3.

To test your installation and configure your board, run the InstaCal utility you installed in the previoussection. Refer to the Quick Start Guide that came with your board www.mccdaq.com/PDFmanuals/DAQSoftware-Quick-Start.pdf for information on how to initially set up and load InstaCal.

Installing the CIO-DAS08/JR

Optional analog output capability
You can add analog output capability to the CIO-DAS08/JR with the CIO-DUAL-DAC upgrade kit. Thiskit includes a two channel D/A AD7237 chip that when installed add two analog outputs to the board.
To install, insert the AD7237 chip into the socket labeled U13. Align the notch or dimple indicating pin 1
on the chip with the notch in the white silkscreen outline printed on the board at the U13 position. Details
on the CIO-DUAL-DAC kit are available on our web site at www.mccdaq.com/isa-data-acquisition/CIODUAL-DAC.aspx.

Calibrating the CIO-DAS08/JR
You can quickly calibrate the CIO-DAS08/JR using InstaCal. The CIO-DAS08/JR has a fixed input range anddoes not have any input amplification or gain/offset compensation electronics. When using the optional
Universal Library, all compensation for gain/offset errors is done in software after the signal is acquired. Thegain and offset calibration factors are stored in the CB.CFG configuration file and applied to the analog
samples after they are acquired.
Run the Calibrate option from InstaCal to set the calibration factors.
