IBM RT PC 8-Port Asynchronous MIL-STD 188 Adapter
The IBM RT PC 8-Port Asynchronous MIL-STD 188 Adapter
contains eight asynchronous adapters. When attached to the
8-Port Asynchronous MIL-STD 188 Adapter, the 8-Port Cable
Assembly - RS-232C/MIL-STD 188 provides eight lO-pin connector
ports. The polarity of the mark bits on each port can be set using
switch 1. The 8-Port Asynchronous MIL-STD 188 Adapter uses the
I/O channel to communicate with the 32-bit processor.
Notes:
1. All 8-port adapters installed in the system unit and expansion
unit must use consecutive address ranges starting with address
range 1.
2. Interrupt levels cannot be shared between the system unit and
the RT PC 6192.
3. All interrupt levels are shared, but they cannot be shared with
any other type of adapter.
