Seatalk-1 to NMEA0183 conversion

[SCV]

We have a Raymarine ST1 network on our yacht (3 pin connector) and wish to connect it to a NMEA0183 (RS232) device. Does anyone have any background on the ST1 protocol?
I gather it's bi-directional serial but that's about it! NMEA0183 I'm happy with and this is no problem.

Cheers,
Tim.

Hey friend, here's some information. This is what I found online. I hope it helps, and I think it's an RS422 protocol.
