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?
