Measurement Computing PC104-DAS08 - Manual (Page 6)

1.2 .1 Setting the Base Address Switches
Select a base address from those available in your system. The PC104-DAS08 uses
eight addresses.
Set the switches on your base address switch as shown on the diagram. Unless there
is already a board in your system using address 300 hex (768 decimal), leave the
switches as they are set at the factory.
In the example shown in Figure 1-2, the switches are set for base address 300h.

Certain addresses are used by the PC, others are free and may be used by the
PC104-DAS08 and other expansion boards. Refer to Table 1-1 for PC addresses.
