Chapter 1
Introducing the CIO-DAC08
Overview: CIO-DAC08 features
The CIO-DAC08 has 8 channels of 12-bit analog output (one D/A per channel). Analog outputs are dual-DAC
AD7273s (two analog outputs per chip), with each output buffered by an OP07. The CIO-DAC08 is compatible
with MetraByte's DDA-06 but lacks digital outputs. Software designed for the DDA-06 will operate the analog
outputs.
Analog output ranges are switch-selectable for a Bipolar or Unipolar range. Bipolar ranges are ±10 V, ±5 V,
and ±2.5 V. Unipolar ranges are 0 to 10 V, 0 to 5 V, and 0 to 2.5 V.
The analog outputs are controlled by writing a digital control word as two bytes to the DAC's control register.
The control register is double buffered so the DAC's output is not updated until the second byte (the high byte)
is written.
Each analog output pair is jumper-selectable for either individual or simultaneous update. When a DAC pair is
set for simultaneous update, writing new digital values to the DAC's control register does not update the DAC's
voltage output. Update of the output occurs only after a READ from the board's addresses.
The board also features a wait state generator that you enable with an on-board jumper.
Software features
For information on the features of InstaCal and the other software included with your CIO-DAC08, 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-DAC08 User's Guide Installing the CIO-DAC08
Unpacking the CIO-DAC08
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DAC08 from its packaging, ground yourself using a wrist strap or by
simply 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 by
phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [e-mail]
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-Software-
Quick-Start.pdf.
Configuring the CIO-DAC08
The CIO-DAC08 has one base address switch, one bank of gain switches for each analog output channel, a
simultaneous update jumper for each DAC pair, a "power-up state" selection jumper, and one wait state jumper
which you must set before installing the board in your computer. The InstaCal calibration and test program
included with the CIO-DAC08 will show you how to set the switches. Run InstaCal before you open your
computer and install the board.
The CIO-DAC08 is shipped with the factory-default settings listed below.
Factory-configured default settings
Board label Switch/jumper description Default setting
ADDRESS DIP switch for setting the base address 300h (768 decimal)
WAIT STATE Jumper to enable a wait state OFF position
XFER Jumper to select simultaneous or single channel
update for each DAC channel pair
Single channel update
0through 7DIP switches to set the analog output range ±5V
PWR UP Jumper to select the power up and reset state STD position — standard (undefined
output values at power up)
Before installing the CIO-DAC08 in the computer, verify that the board is configured with the settings that you
want. Review the following information to change the default configuration of a jumper or switch on the CIO-
DAC08 board.
Base address switch
Before you install the CIO-DAC08 in your computer, set the base address by using the dip switch labeled
ADDRESS located on the board.
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 base address selection.

CIO-DAC08 User's Guide Installing the CIO-DAC08
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 Fi shows the settings for the factory-default base
address of 300 hex.

In the default configuration shown in Fi , 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.

The CIO-DAC08 Base switch can be set for an address in the range of 000-3E0, so it should not be hard to find
a free address area for your CIO-DAC08. If you are not using IBM prototyping cards, or some other board
which occupies these addresses, then 300-31F HEX are free to use. Addresses not specifically listed, such as
390-39F, are free.
