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.
