RL70C not communicating with RC631

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum dkritter,

Q1. I believe that these two units should be able to share chart and radar screens via the HSB2. However I cannot get this to happen. About the only thing they seem to share are the cursors. Meaning RL70 cursor shows on RC631 and the RC631 cursor shows on RL700. But that is it, no chart or radar sharing.

A1. SeaTalk communications is responsible for sharing alphanumeric GPS, instrument, navigational, and system state data. Hsb2 communications is responsible of sharing of radar imagery, fishfinder imagery, and cartography. Please click here to view a FAQ addressing troubleshooting hsb2 communications. Unfortunately, should one or more of the displays have failed hsb2 communications circuitry, then it must be replaced, as Raymarine's Product Repair Center can no longer service these displays.

Q2. But I would like to keep all the ST60's, 400G course computer and ST6001+. From what I can dechiper I will need to mate the seatalk with the seatalkng, is that correct? What other considerations? Lastly, which autopilot control head would replace the ST6001 and still keep the course computer and the other autopilot peripherals?
