Isolated control unit, single power supply (S2 and S3
computers only)
If you have two control units, we recommend that you connect one to each
SeaTalk terminal. In the following illustration:
• the SmartPilot computer provides power to the SeaTalk system
• one control unit is connected on its own to SeaTalk A so it is isolated against
any possible failure of SeaTalk B
If the SeaTalk B line fails, the isolated control unit will switch to Standby mode as
a safety measure. By pressing auto on the isolated control unit you can regain full
autopilot control.

Depending on the number of SeaTalk units and the total length of SeaTalk cabling,
Note:
you may need to provide12 V power supply to each end of the SeaTalk bus ('ring-main'
style). Refer to the instrument handbook for more information.

Separate SmartPilot computer and instrument power

Another option is to provide separate power supplies to the SmartPilot computer
and SeaTalk system so you can have independent, switched instrument and pilot
systems.
DO NOT connect the SeaTalk RED wire at the SmartPilot terminal
Note:

WARNING: Use correct fuse

The fuse supplying the instrument system MUST be rated at 5A or
less.
The behavior of the computer and the instruments now depend on where power
is applied to the system.
