A second bridge mode, bridge mode B, provides full cross point switching. Up to a
maximum of 64 cameras are available with the restriction that coaxial telemetry (C
Type) is only available when cameras are switched to monitors 1 to 16. The
camera inputs are connected from one 'monitor node'to the next via loop-through
cables, giving all monitors access to all cameras. The filtering on the loop-through
connections limits the availability of C Type telemetry and also some camera signal
degradation may occur as it passes down the chain of loop-through circuits.
Camera control over RS422/RS485 is fully supported.
NOTE
Alarm handling and multi-hop networking are not supported in bridge mode B
The special network address mode used to select bridge mode B is detailed in
Tab. 34.

The PCCON networking connections are as bridge mode A and again the bridge
node serial port used determines the monitor numbers allocated to the monitor
node, as per Tab. 35.
