I/O Expansion Bus
Each chassis has six RS-485 I/O expansion bus ports at the top left corner of
the backplane. There are two sets of
ports for channels A, B, and C,
providing for two triplicated serial
communications paths between chassis.
One set of cables is required for each
Expansion Chassis and for the RXM
Chassis which houses the primary
RXM Module set. The standard length
of a cable set (Model 9000) is 6 feet—
longer cables are available if needed.
The triplicated I/O bus transfers data
between the I/O modules and the Main
Processors at 375 kilobits per second.
The communication bus runs between
the Main Processors and the communication modules at 2 megabits perKeyswitch for System Control
The Main Chassis has a four-position
keyswitch which controls all the
chassis in the system. The keyswitch
setting is readable by Tricon controllers, TriStation 1131 software, and the
control programs. Switch settings are:
RUN—Normal operation with readonly capability. The Main Processors
