Raytheon RL70 Radar - adding 2nd Display?

[rgesner]

I have a perfectly functional Raytheon Pathfinder RL70 Radar with a monochrome display at the nav station. I'd like to add a second display at the helm, which it looks like I can get pretty inexpensively on Ebay.

Can any RL70 function as a second display?
Can the newer color RL70C function as a second display for the older RL70?
Is adding a second display simply a matter of running power to it and connecting it to the 1st display via Seatalk?

Thanks - Rusty

You also need the Raymarine HSB cable between the plotters.

I have a RL 70 B/W in the box. Pm me if interested
