Installing the transducer
The cabling must be done before installing the transducer.
Context
The transducer is mounted on the ship's arrangement for the transducer. This may be on
a pole lowered through a moon pool or a hull unit.
The location of the transducer arrangement must be as far away as possible from
thrusters, aerated water, noise sources or other equipment sensitive to acoustic noise in
the water.

Installing the Responder Driver Unit
The Responder Driver Unit provides responder trigger signals to responders. The RDU
is a stand-alone unit and can be mounted horizontally or vertically.
Prerequisites
The unit should be located where it is most suitable for connecting the cables to the
responders. This can be close to the Remote Operating Vehicle (ROV) operation room.
The unit must be installed so it is easily accessible for operators to check the working
condition of the responder trigger status diodes.
