Unpacking the CIO-DAC02
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DAC02 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

Configuring the CIO-DAC02
The CIO-DAC02 has one base address switch, one wait state jumper, and one output range jumper which you
must set before installing the board in your computer. The InstaCal calibration and test program included with
the CIO-DAC02 will show you how to set the switches. Run InstaCal before you open your computer and
install the board. The CIO-DAC02 is shipped with the factory-default settings listed below.

Before installing the CIO-DAC02, 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-DAC02 board.
Base address switch
Before you install the CIO-DAC02 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.
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 base
address of 300 hex.
