[CA] [CA11] replacing C80 with two E80's Seatalk connection

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Andy,

Q. IF the E80 at the helm is connected to all the seatalk instruments (through spliced seatalk 3 wire cable - from the C80 wiring), can I direct connect the nav station E80 to the Helm E80 with the high speed cable seatalk (high speed network cable), and be able to share seatalk data between these two E80 units??
A. Yes. The system's Data Master MFD will share all data received via its SeaTalk and NMEA 0183 communications with the system's other E-Series Classic MFDs, when these MFDs have been interfaced via Ethernet network (SeaTalkhs) communications. The SeaTalkhs sockets of these two MFDs were meant to be linked to one another via one of the following means:
- a pair of SeaTalkhs (M) to RJ45 cables which have been joined with a SeaTalkhs Crossover Coupler
- a pair of SeaTalkhs (M) to RJ45 cables which have been connected to a SeaTalkhs Network Switch (retired)
- a pair of RayNet (F) to RayNet (F) Cables which have each been connected to a HS5 RayNet Network Switch and have each been adapted with an A80513 RayNet (M) to SeaTalkhs (M) Adapter.
