Powering SeaTalk
The SPX SmartPilot normally provides power to the SeaTalk system. However your
system may require an additional or separate power supply.
Power supplied to both ends of the SeaTalk bus.
Depending on the number of components on the system and the total length of data
cabling, it may be necessary to provide a 12 V power supply to each end of the data
bus (‘ring-main’ style):
•
Connect the SeaTalk bus as normal.
•
Connect a second SeaTalk cable to the SmartPilot and route it to the far end of the
SeaTalk bus.
•
For the second cable, do NOT connect the SeaTalk YELLOW wire at the SPX
SmartPilot SEATALK terminal.
