Appendix E Using Your PC-DIO-96 (Non-PnP) Board

PC-DIO-96/PnP User Manual E-4 © National Instruments Corporation

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.

Base I/O Address Selection

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.
