Host Computer Interface Card

Motorola Preparation and Installation 2-3

The host interface card resides in the PC-workstations I/O bus; the ADS user interface

software communicates with the card through this I/O address block. The host interface

card address block may be changed to start at one of three addresses as described in

Table 2-1.

If the host interface card address block is changed from the default $100, the selected

address must be specified to the ADS. This may be done in one of the following three

ways:

• Set the environment variable ADMADDR: >SET ADMADDR=200

• Issue the ADS command HOST: > host io 200

• Use the -d option on the ADS command line: >ADS56300 -d 200

To install the host interface card properly, position its front bottom corner in the plastic

card guide channel at the front of the PC-workstation chassis. Keeping the top of the host

interface card level and any ribbon cables out of the way, lower the card until the card

connectors are aligned with the PC-workstation system board expansion slot connectors.

Using an evenly distributed pressure, press the host interface card straight down until it

seats in the expansion slot.
