Chapter 1

Introducing the CIO-DAS08
Overview: CIO-DAS08 features
The CIO-DAS08 is a multifunction analog and digital I/O board supported under popular Microsoft® Windows®
operating systems.
The CIO-DAS08 provides eight single-ended channels of 12-bit analog input, three 16-bit down counterchannels, three digital input, four digital output, and 24 digital I/O lines.
The analog input range and polarity are selectable with an on-board switch. Bipolar input ranges are ±10 V and±5 V. The Unipolar input range is 0 to +10 V.
You select the base address with onboard dip switches. The interrupt level and pacer source are jumperselectable. You can set the pacer source to use the internal PC clock or an external clock.
The CIO-DAS08 has a 37-pin analog connector and an onboard 37-pin digital connector.
Four digital output bits and three digital input bits are provided on the board's main connector. A 37-pin
connector mounted on the board provides 24 digital I/O bits based on the 82C55 specification. The 24 bits are
configured as two eight-bit ports and two four-bit ports. Each of these ports may be individually programmed as
input or output.

Software features
For information on the features of InstaCal and the other software included with your CIO-DAS08, refer to the
Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.

CIO-DAS08 User's Guide

Installing the CIO-DAS08

Configuring the CIO-DAS08The CIO-DAS08 has two sets of switches and two jumpers that should be set before installing the board in the
PC. Mounted on the board is a bank of DIP switches for setting the base address, a jumper for setting theinterrupt level and a jumper for setting the pacer source to either the internal PC Clock source or an external
clock. A bank of four switches on the connector bracket is used for setting the analog input range.
The InstaCal calibration and test program included with the CIO-DAS08 will show you how to configure theboard. Run InstaCal before you open your computer and install the board.
The location of each switch and jumper on the CIO-DAS08 is shown in Figure 1.

Installing the CIO-DAS08

Base address
Before you install the CIO-DAS08 in your computer, set the base address by using the dip switches labeled
ADDRESS located on the board. The easiest way to set the base address switch is to let InstaCal show you thecorrect settings. 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), leave the switches as
they are set at the factory. The example shown in Figure 2 shows the settings for the factory-default baseaddress of 300 hex.

Figure 2. Base address switches (300h shown)

In the default configuration shown in Figure 2, 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).
A complete address is constructed by calculating the hexadecimal number which corresponds to all the address
bits the CIO-DAS08 can respond to. The range of base addresses is 000h to 3F0h. Certain address are used by
the PC, others are free and may be used by the CIO-DAS08 and other expansion boards. Refer to the following
table.
Disregard the numbers printed on the switch
When setting the base address, refer to the numbers printed in white on the printed circuit board.

Interrupt levelSet the interrupt jumper only if your software requires it. If you do set the interrupt jumper, check your PC's
current configuration for interrupt conflicts. Do not use IR2 in PC/AT class machines (or higher).
Use the jumper block labeled INT above the PC bus interface (gold pins) to set the interrupt. The board isshipped with the jumper in the "X" position, which means that no interrupt level is set (Figure 3).

INTFigure 3. Interrupt level select jumper (no interrupt level set)

To pace conversions through hardware (either the on-board pacer or an external clock), move this jumper toanother position. The CIO-DAS08 can use interrupt levels 2 through 7. Refer to the following table for sometypical interrupt assignments on a computer. The levels most often available are 5 and 7.

With revision 4 and higher hardware, you can use the on-board pacer clock to trigger A/D conversions bysetting the clock source jumper (labeled J on the board) to the 6/24 position. This setting routes the pacer output(pin 6) to the interrupt input (pin 24). By default, this jumper is configured as not connected (NC). Refer toFigure 4.

Figure 4. Clock source jumper (default setting)Note: to pace conversions with the on-board pacer, you must also select a hardware interrupt by configuring theinterrupt level select jumper (discussed above).

Programming and Developing Applications
After following the installation instructions in Chapter 2, your board should now be installed and ready for use.
In general there may be no correspondence among registers for different boards. Software written at the registerlevel for other models will not function correctly with your board.

Programming languages
Measurement Computing’s Universal Library provides access to board functions from a variety of Windows
programming languages. If you are planning to write programs, or would like to run the example programs for
Visual Basic or any other language, please refer to the Universal Library User's Guide (available on our website at www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf).

Packaged applications programs
Many packaged application programs now have drivers for your board. If the package you own does not have
drivers for your board, please fax or e-mail the package name and the revision number from the install disks.
We will research the package for you and advise how to obtain drivers.
Some application drivers are included with the Universal Library package, but not with the application package.
If you have purchased an application package directly from the software vendor, you may need to purchase ourUniversal Library and drivers. Please contact us by phone, 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

Register-level programming
You should use the Universal Library or one of the packaged application programs mentioned above to control
your board. Only experienced programmers should try register-level programming.
If you need to program at the register level in your application, refer to the Register Map for the CIO-DAS08.
This document is available on our website at www.mccdaq.com/registermaps/RegMapCIO-DAS08.pdf.
