This telegraph system installs the transmitter in the wheelhouse and the receiver in the main engine control area (engine control room or near the machine), and corresponds utilizing the synchronicity of the self-synchronizing machine. Commands and responses can be exchanged with simple operations between the transmitter and the receiver, concerning the operating conditions of the main engine.
A potentiometer for the control of the main machine can be installed into the transmitter TAT-300 (B5). A type with the fine-tuning function in the handle is also available.
