Wiring GPS to Furuno NX300

[Sy-Revolution]

Hi Everyone,
I spent the day installing my Christmas present of a Furuno NX300 navtex receiver. It's working ok except that I'm confused as to which wires I need to connect to my Raytech GPS (green+ yellow) wires. I tried wiring green to green and yellow to yellow but that didn't work and knocked out the GPS feed to the radio. Reading the installation guide it seems just to mention how to wire up for a Dsub to PC connector but I couldn't find any mention of GPS wiring. The colours I have on the wiring loom are yellow,green, white, blue & a bare wire plus red and black for +- respectively.
Can anyone help ?

Cheers,

Crispin

The connections are on pS-1 of the manual, White +ve, blue -ve.

So does that mean that I connect the furuno white to raystar yellow, and furuno blue to raystar green?

Please I'm a dunce........

I'm not familiar with the raystar colour code, but yellow as +ve NMEA sounds right. BTW, unless you want to use the nav. repeater function, GPS connection is hardly worth it IMHO. All it does is select the nearest 1 or 2 stations automatically. It's just as easy to re-select manually if you go far afield.

Ok I'll give it a go, thanks earlybird.

You are about to be out-dunced!!

Why would one wish to connect a Navtex to a GPS? Reason I ask is that a gentleman on this forum [yes, there are many, despite what you read to the contrary] recently gave me a Furuno Navtex so I'm interested to learn what it can do.

Raytech is software. There isn't a Raytech GPS. You may have a Raystar GPS. These have different wiring colours, according to model. If you tell us which GPS you have, you might get a helpful reply.

[/ QUOTE ]Two reasons. Firstly, if position info from the GPS is provided, the Furuno navtex will automatically select the relevant navarea. Secondly, the Furuno navtex can display nav data (L/L, speed, etc) on its screen.

Sorry, it's a Raystar, the one before the new 125. Can't remember the model number, It's connected to my Raymarine Ray54 dsc radio with two wires, green and yellow, and the C120 similarly.

Thanks for that.

If your GPS is a Raystar 120, yellow is NMEA out, and screen is ground. For the NX300, white is NMEA in, I believe. So connect Raystar yellow to Furuno white.
