Seatalk Cable

[Stoshak]

I'm about to do a little rewiring of the electronics which will need some Seatalk cable. It seems rather expensive from Raymarine, but I can't find another source of screened two core cable with conductors 1.0mm dia.
Where should I look - or is the screenig really necessary?

Similarly, I have seen multicore 'alarm cable' recommended for NMEA use. Does this mean that it doesn't need screening?

It's a nightmare!

Have you tried Raymarines Ebay Shop most have been used or New surplus

I recently cut and spliced Raymarine cable, and used the screening stripped from some coax.

I also used twin core alarm wire for getting nmea from my handheld Garmin gps to the Raymarine radar/chartplotter (cos I didn't want to fork out for an external active antenna)

That's an interesting ebay site, I shall have to watch out to see what is offered. /forums/images/graemlins/smile.gif
Thanks

Twin core screened cable is usually used for microphone applications. I haven't yet cut a Raymarine cable to see what's inside - but it's in the game plan for this winter! You can get thin mic cable from any electronics company: Maplin, Rapid, etc.

You're absolutely correct re microphone leads, but none seem to have 1.0mm dia conductors

Inside the Raymarine seatalk cable is Red, 12V Yellow, signal, and overall screen 0volts.

I''ve just run in and extended the seatalk signal yellow and screen over cat5 ethernet cable, about 5 metres with no errors recored on the E series diagnostics.

If you are using the seatalk power then a thicker cable may be better.

I suppose ethernet is OK for the signal, and a separate 12v supply with thicker cable would do the trick and not need screening

Seatalk cable is actually a bit smaller than you've quoted - the conductors are about 0.5sq mm in area. You can get similarly sized screened 2 core microphone cable from people like Maplin for about £1.50 a metre plus delivery, or loose Seatalk cable for £2 including delivery from JG Technologies. If you only need a few metres, you might as well buy the Seatalk cable and keep the colours right.
