• Because all of the receivers and transmitters are on the same
communication channel, TSAM 1 and TSAM 2 are connected together
through their P103 expansion ports.
• The system transmitters are connected to the TSAMs. Transmitters 1
through 8 are connected to TSAM 1 and transmitters 9 through 16 are
connected to TSAM 2.
• TIB 2’s Force Select line is connected to TIB 1’s Force Select line, not
to TSAM 2’s Force Select line.
• The comparator’s vote lines are connected to the Comparator I/O
Modules and to the TSAMs (this allows the TSAM to steer based on
receiver activity and comparator voting).
• Assume the TSAMs are programmed for Instant Update mode (the
TSAM will steer as soon as a vote occurs).
During system installation, the following setups must be performed:
• TSAM 1 is setup as a MASTER (from the front panel switches).
• TSAM 1 is programmed for 1 expansion TSAM (from its RS-232
programming port).
• TSAM 2 is setup as an EXPANSION (from the front panel switches).
• TIB 1 is programmed with CIB 1’s unit address and TIB 2 is
programmed with CIB 2’s unit address (using the steps given in
section 7.1).
• For both CIB 1 and CIB 2, option switch 3 must be set to the UP
position to enable operation with the TIBs.
• For both TIB 1 and TIB 2, the transmitter bank select switches must be
set for bank 0 since the CIB only supports receiver bank 0.
The system operates the same as the system in the previous example. When a
receiver becomes active and is voted by the comparator, the TSAM will steer to
the corresponding transmitter. The TIB monitoring that transmitter will detect the
steering change and update the HIB with new active transmitter status.
When a receiver is FORCE VOTED from the PC, the CIB controlling that
receiver will send the FORCE VOTE command to the comparator. The TIB
associated with that CIB will also receive the FORCE VOTE command and will
command the TSAM to steer to the transmitter that corresponds to the FORCE
VOTED receiver.
