I just finnished replacing my C80 with an E80 on my upper
helm and an E80 on my lower helm. The reason I installed an E80, was to gain the ability to have two chart plotters at two different stearing station on my 42'
Trawler.
Some of the connections on the E80 are different then a C80. The
radar connection is the same, the
power connection is the same, but the
Seatalk cable is different. The three pronged crescent
Seatalk cable that is on the C80 is not present on the E80.
You have to connect the
GPS and
Autopilot with the Seatalk/alarm out cable. Remember to
power the
GPS and the Seatalk cable with 12V. All properly fused of course.
If you aren't planning to
network two chart plotters there is not much sense in replacing the C80 with the E80.
The two chart plotters are then connected with an HS cable
