Base I/O Address Selection
PC-DIO-96/PnP User Manual
The PC-DIO-96 is configured at the factory to a base I/O address of
hex 180 and to interrupt level 5. These settings (shown in Table E-2)
are suitable for most systems. However, if your system has other
hardware at this base I/O address or interrupt level, you need to change
these settings on the PC-DIO-96 (as instructed on the following pages)
or on the other hardware. Record your settings in the PC-DIO-96/PnP
Hardware and Software Configuration Form in Appendix F, Customer
Communication.

(factory setting)
An onboard switch setting determines the board base address. The
address on the PC I/O channel bus is monitored by the address decoder,
which is part of the I/O channel control circuitry. If the address on the
bus matches the selected I/O base address of the board, the board is
enabled and the corresponding register on the PC-DIO-96 is accessed.
