Hardware Installation

Port Addresses

Port addresses are configured with the jumper block JB3 on the

Xtreme/104 Opto adapter. Jumpers A, B, and C select a set of

port addresses for the ports.

Status Port Addresses

Some operating system device drivers can utilize an Interrupt

Status Port, for example Windows NT offers it as an option and

for SCO Unix it is mandatory. This can improve your system’s

efficiency. The Xtreme/104 Opto offers a status port and this port

s enabled and disabled using jumper F on jumper block JB3. i

Please refer to Table 1 for a list of supported status port addresses

and to Figures 1 and 2 for a description and location of jumper

block JB3.

Technical Tip:

Please make certain that the Status Port Enable jumper is disabled if

your application is not using the Status Port. This eliminates the

possibility of an address conflict with another device in your system.

Custom Port Addresses

You can generate other port addresses by making changes to the

CPLDs found on the Xtreme/104 Opto adapter. If you require

specific port addresses not listed in Table 1 please contact a

Connect Tech Customer Service Representative for further

nformation. i
