Power supply connections

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 No. of instruments Power connections

Up to 10 m 13 maximum

Up to 20 m 7 maximum
