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.
