Amcom II Model 2825R Two Diver Rack Mount Communicator

The front panel contains all the controls and connections required to operate the
communicator. It is intended that the divers will be connected to the communicator using the
rear chassis MS connector but the front panel 5-way binding post allows for ad-hoc
connections when required.

The rear chassis contains the AC power inlet, recorder output and an MS connector with all
the tender and diver connections. This allows a clean installation by routing all the
connections from the back in the rack. The rear tender connections allow for the installation
of a separate, remote tender station located away from the rack.
