power switch
The course computer can provide power to the
SeaTalk
ng
backbone. This will provide power to certain
equipment connected to the backbone (e.g. ST70 pilot
controller and instruments).
Set the SeaTalk
ng
power switch on the connector panel
to the appropriate position:
•
ON
— The course computer will supply power to the
SeaTalk
ng
backbone. Ensure that there are no other
power feeds connected into the backbone.
•
OFF
— The course computer will not supply power
the SeaTalk
ng
backbone. Ensure that there is a
separate power feed to the SeaTalk
ng
backbone.
Important:
Use correct fuse. The fuse supplying
the SeaTalk
ng
system MUST be rated as per the
value shown on the connector panel.
