SA320 GPS with Raymarine RL80C Pathfinder

[joker64]

As others have written here, my GPS antenna stopped working. It was old and rusted out, so out with the old and in with an Evermore SA320 RS232.

I thought that it would be a direct and easy fit. Fortunately, I tried a test run before running the wires.

I am connecting it via a wiring block. The 0183 cable from the chartplotter, a Raymarine RL80C Pathfinder, has the usual wires, Red for power, Black ground, shield, Green +, Blue -, Orange +, Yellow -.

SA320 has Red Power, Black ground, shield (instructions say to connect to ground), Green +, White -, and a blue that they say isn't used for this.

Voltage is good, 12V system on the boat, and the unit accepts from 9-32V.

Once connected I get a persistent NO FIX message. At one point, I tried the Orange/Yellow combination instead of the Green/Blue, and it seemed that it was now searching for satellites. At this point I was just twisting the wires together to see what would work. Thinking it was now good, I disconnected the wires to attach them to the wiring block.....Then, nothing....and still nothing.

Unless someone can suggest where I'm going wrong with the connections, I think my next step is to wire it up to a RS232 plug, and test the antenna via the laptop. That'll take a little time.

Any other ideas? I've tried all the wiring combs that I can. I read on another post, somewhere on the old internet, and one guys says that there was a software incompatibility between the older Raymarine system, and the newer SA320. Does that ring true to anyone?

Thanks

Resolved. Red to Red, Black to Black, Green + to Green +, Shield from gps to blue - on the chartplotter.
