CAUTION
When instruments are connected to SeaTalk, ensure that the
power supply for the SeaTalk 12 V line is protected by a 5 A fuse.
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:
Cable run
Up to 10 m
Up to 20 m
SeaTalk cable
Cable from Depth transducer
Cable from Speed transducer
