3.8 800MHz 8Ch. Channel Module Sub-Rack (50-078003)
3.8.P 800MHz Channel Module Sub-Rack Photographs
Photographs of this sub-rack are unavailable.
3.8.1 Description
The channel modules are built into a sub-rack which is the equivalent height of a 3U shelf. Each sub-
rack has eight channel selective modules (3 sub-racks=24 channels) and two channel control
modules that are DIP switch banks that configure the frequencies for the channel modules, see below
for channel module programming.
Each channel module has an alarm (alarm which is summed to form an overall alarm pair for the
whole sub-rack, that terminates at the rear-mounted 9-way alarm ‘D’ connector, pins 1 & 2.
