Transceiver Unit

The transceiver cabinet is by default fitted with a heat exchanger. This means that a stable internal temperature and humidity is ensured independant of the sonar room environment. It will also prevent dust particles from contaminating the electronic circuitry.

The connections for power and communication are made under the cabinet. The transducer cable is connected using a large proprietary plug on the side wall.

The Transceiver Unit has been designed to be mounted on the bulkhead. It is fitted with powerful shock absorbers to withstand the violent motions of a vessel at sea.
