SeaTalk to SeaTalk ng Conversion

[Tom - Raymarine - Moderator]

Hello Jones,

The E80 used a specific (supplied) Seatalk1 cable, which ended in bare wires. You would need to splice this, colour-for-colour, to the standard 3-pin Seatalk cable supplied with the first convertor. You can see further details on the E80's Seatalk cable in its installation manual.

The same essentially applies with the RS125, except that the wiring isn't colour-for-colour. The RS125 could transmit either Seatalk or NMEA0183 data formats depending on the voltage applied to its green wire, where 0V was NMEA0183 and 12V was Seatalk mode, so to connect to the convertor you would wire as shown in the top illustration in the section To connect to the RS125 into a SeaTalk system.... in the RS125's installation guide to the 3-pin Seatalk cable supplied with the second convertor.

Regards,
Tom
