Configuration

The PC-DIO-24 contains one DIP switch and two jumpers to configure
the base I/O address, interrupt level, and interrupt enable signal.
Figure D-1 shows the location of DIP switch U9 and jumper
sets W2 and W3.

The PC-DIO-24 is configured at the factory to a base I/O address of hex
210, to use interrupt enable line PC4, and to use interrupt level 5. These
settings (shown in Table D-2) are suitable for most systems. However,
if your system has other hardware at this base I/O address, interrupt
enable line, or interrupt level, you need to change these settings on the
PC-DIO-24 (as described in the following pages) or on the other
hardware. Record your settings in the PC-DIO-24/PnP Hardware and
Software Configuration Form in Appendix E, Customer
Communication.
