RANGE
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.
Address not specifically listed, such as 390-39F, are free.
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).
