3 HARDWARE INSTALLATION

The CIO-DAS08-AOx has three banks of switches and three jumper blocks which must be set before installing the board in your

computer.

3.1 BASE ADDRESS

The base address of the CIO-DAS08-AOx is set by switching a bank

of DIP switches on the board (Figure 3-1). This bank of switches is

labeled ADDRESS and numbered 9 to 4.

Ignore the word ON and the numbers printed on the switch

The switch works by adding up the weights of individual switches to

make a base address. A 'weight' is active when the switch is down.

Shown to the right, switches 9 and 8 are down, all others are up.

Weights 200h and 100h are active, equaling 300h base address. Refer

to Table 1-1 for a list of standard PC addresses.
