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
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 |
