Power supply connections
SeaTalk systems
Ensure that the power supply for the SeaTalk bus is protected by a 5 A fuse or
circuit breaker.
Systems with a large number of instruments on the SeaTalk bus may require
connections to the power supply from each end of the system (‘ring-main’ style),
to maintain sufficient voltage throughout the system.
This requirement depends on the total length of the cable run and the total
number of instruments in the system, as follows:
CAUTION: Protect the power supply
Ensure that the 12 V power supply for the instrument is
protected by a suitably rated fuse or protective circuit breaker.
