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 DFlex-4/104 offers a status port and this port is

enabled and disabled using DIP switch 6 on switch block SW1.

When DIP switch 6 is in the on position the status port is enabled

and when it is in the off position it is disabled. Please refer to

Table 2 for a list of supported status port addresses and to Figure

4 for a description and location of switch block SW1

Technical tip:

You should set DIP switch 6 on switch block SW1 to the off

position if you are not using the status port for your application.

This eliminates the possibility of an address conflict with another

device in your system.
