Raymarine Nmea0183 to 3rd party GPS antenna

[craig_c]

Having a bit of trouble here,

Bought a 3rd party antenna that was uber cheap however the raymarine cable I have has conflicting wiring to what raymarine says

On the Nmea 0183 cable I have

Brown
yellow
green
white
shielding

and on the antenna I have

black
yellow
green
brown
red
shielding

Anybody done this before?

Not done it, but the antenna will most likely have a +\- supply in addition to the NMEA in/out. You will probably have to run a separate supply. Did the antenna come with a wiring diagram?

[craig_c]

unfortunately not Dave

Tomorrow I will try separate power source and the brown and yellow

sounds like a plan

I wouldn’t take it as read that the connections are colour to colour. The yellows may not necessarily connect together. I think I might have an old NMEA gps puck kicking around somewhere. I’ll see if I can dig some info.

It might not help but from my ICOM VHF manual, they list the colours in red above.

the GPS guy kindly came back to me this morning and sent me this

I don't think this works, I've tried every possible combination and still not a single satellite. The antenna was outside with me inside fiddling with wires however no combination seems to make it go. I do know Raymarine are very fussy with using other parts so maybe they have done something that wont allow this

[craig_c]

YES!!!!!!!!!!!!!!!! Just when I think all hope is lost

We have signal!

GPS side - Antenna side

Yellow - Green
White - Yellow
Red +ve battery
Green & Brown together on GPS side
Negatives and shielding to -ve battery

Result [emoji106] if it’s a cold start, it can take up to an hour for the GPS to lock on, depending on its view of the sky.
