Peter: you are refering to the newer connectors.

The ST50 series used round connectors with three pins.
Each instrument had two about 10cm (4inches) long wires coming
out of their backs terminated with these plugs. One was male and the other
female.
ST50's SeaTalk signal is compatible with newer series like the ST80,
ST60 and the current ST40 and ST60+. The connectors are not.
The ST50 connectors has Raymarine part number Q017 (or had, don't
know if they're available any more). Raymarines SeaTalk cable (without
connectors)
has the partnumber Q018 and has one red, one yellow and unisolated wire.
Offcourse you can always cut the ST50 cable on the back of an instrument and
use any 3pole connector to connect to your SeaTalk bus.

Regards, TomS

Hi sailors, I need parts for additional instuments; connecting wires

parts?? Raymarine doesn't list nor does Goggle. Thanks Chris

Any three-conductor (or two conductor and shield) #22 or so wire
should do.

AutoHelm used molded connectors on their pre-made cables, but you can
use individual 0.187" "faston" crimp connectors instead.

Correction - I think the connector tabs are actually 0.125" wide....
