9.1 Connecting SeaTalk equipment
You can use SeaTalk to connect the autopilot system to:
additional SeaTalk control units: you can use any control units 
to operate the autopilot and view autopilot information
SeaTalk equipment (such as wind, navigation, radar and GPS): 
the autopilot system can use information from this equipment 
to enhance course keeping and provide additional features 
(such as waypoint navigation)
you can also display information from the SeaTalk equipment 
on the autopilot control unit
Possible systems
When connecting SeaTalk equipment, you have a range of options 
depending on whether you want to:
provide an ‘isolated’ control unit (for systems with more than one 
control unit – see next page)
provide power separately to the course computer and main 
SeaTalk bus
The following illustrations show some typical ways to connect 
simple SeaTalk systems. 
CAUTION:
If your autopilot system includes more than one control unit, 
we strongly recommend connecting the main control unit to one 
course computer SeaTalk port and the additional control unit(s) 
to the other SeaTalk port. This will mean that if either SeaTalk 
system fails, you will still have one operational control unit. 
Single control unit, single power supply
The simplest type of system has the course computer providing 
power to a single SeaTalk system that includes a single control unit 
and several instruments.
