Marine-grade wire for NMEA signals

[DeepFrz]

+1 on what Dave says. Unless you run the cable to a breakout box and then run single pair shielded out to each item as you install it.

Good video extension cables have all pins wired, some skip pin 9.

Pull a proper NMEA 2K stranded twisted pair/shielded cable. In you want extra pairs pull an additional cable.

I havn't boned up yet on NMEA 2000 since I don't have anything yet that needs it. Is it full-duplex, so that one pair both transmits and receives? All my stuff is NMEA 0183, so it needs one pair to transmit, and a separate pair to receive. Then with one high speed and one low speed signal both in and out, that's 8 conductors right there. The chartplotter needs the high speed, but I think the autopilot is happy with low speed.

So I may run a NMEA 2000 cable for future use, then an 8 conductor for all the 0183 stuff, and I should have all I'll ever need.

OK Nick and thanks for the tip.

I did find it at Cables to Go.

I do see that most of the cables there are missing pin 9 as you pointed out.

Yes, but is pin 9 used on your AIS? You can always just buy a connector at a place like Electronic Components Distributor | DigiKey Corp. | US Home Page

Yes, all 15 pins.

1 ground
4x3 = for 3 NMEA connections, bi directional
2 for alarm output

1+12+2 = 15

I found a neat little break out box somewhere, a 15 pin connector with circuit board mounted wire terminations. I have that hooked up at the moment.

#1 NMEA goes to spare chart plotter (Standard Horizion) down below
#2 NMEA to Ray Marine C-80 plotter in cockpit
#3 to ICOM VHF and Pactor Modem

Alarm will go to a Sonalert eventually.

I don't need all 15 wires, but I don't get to say which ones are connected to what. Normal VGA connections killed high speed NMEA to C-80.

Cables to Go 6ft Flexima HD15 UXGA M/M Monitor Cable claims to have all 15 wires "loaded."

Never heard that term before but I think it means they are all there. Seems self evident.
