Software Installation
1.2 HARDWARE INSTALLATION
The PC104-DAS08 has three sets of switches / jumpers that should be set before
installing the board in the PC. There is a bank of DIP switches for setting the base
address, a jumper for setting the interrupt level and a bank of switches for setting the

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.

The BASE switches can be set for address in the range of 000-3F8 so it should not be
hard to find a free address area. If you are not using IBM prototyping cards,
300-31F HEX are free to use.

1.2 .2 INTERRUPT LEVEL SELECT
The interrupt jumper need only be set if the software you are using requires it. If you
do set the interrupt jumper, please check your PC's current configuration for
interrupt conflicts.
Do not use IR2 in PC/AT class machines (or higher).
There is a jumper block on the PC104-DAS08 located just above the PC bus
interface (see Figure 1-1). The factory default setting is that no interrupt level is set
(the jumper is in the 'X' position). See Figure 1-3.
If you need to pace conversions through hardware (either the on-board pacer or an
external clock), move this jumper to one of the other positions (see Table 1-2).
