Connecting to SeaTalk
Power requirements
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 SeaTalk cable run and the
total number of instruments in the system. Before connecting the ST60+ Graphic
Display, ensure that the system with the display included, will receive a
satisfactory power supply. The requirements for power connections are detailed
in the following table.
:
CAUTION: Protect the power supply
