connect RL 70 and RL 80 cable needed.

[Awilson275]

I want to connect my RL 70 display and my RL 80 as a helm slave. What cable do I need ?

you need an HSB2 cable and 2 inline terminators. good luck? probably have to find used online. doubt you'd find them new.

you should also join them with seatalk. (probably needed to share gps)


edit: if they are really old, they may be HSB, or one could be HSB and one HSB2, which would cause issues. this stuff is before my time working on boats... hopefully they are both hsb2 units. you'd have to figure that out
