Standard Horizon RAM Mic

[Markhunter1097]

I've managed to pull two wires out of the 8 pin plug for my RAM mic.
I could solder them back by guessing where they go, but that gives me a 50/50 chance of stuffing it all up.
The blue (speaker) and white(?) wire are free, as are hole numbers 1 and 4.
Anyone know which goes where?
I have also asked Standard Horizon for a wiring diagram which may or may not come.
thx

Same thing happened to mine a few years ago. I sent it to Standard Horizon and they fixed it for me for free — even though it was like five years old.

You should be able to get a pin-out diagram from SH. You might even find it on line.

Here you go...from the GX2360 manual:

4.3 ACCESSORY CABLE
White: External speaker (+)
Shield: External speaker (–)
Red: PA speaker (+)
Shield: PA speaker (–)
Blue: NMEA IN (+) from GPS navigation receiver
Green: NMEA IN (–) from GPS navigation receiver
Gray: NMEA OUT (+) to GPS navigation receiver
Brown: Test port (for the Service Technician)

Looks like white is the external speaker pos and blue is the NMEA pos (from the GPS receiver).

Don't know which model you have.

Hope this helps,

Bill

Bill,

I think the RAM mic plugs into its own special connector and not the Accessory port on these radios.

I could not find the pinout of the RAM connector. I suggest you call Standard Horizon. They have a reputation for fixing little problems like this without a lot of hassle.

It does plug into its own port and there are at least two versions of these cables depending on year/model of radio.

OP: You could just disconnect the other end of the cable and do a continuity test to confirm which pins.

Thanks for all the replies, the model is the CMP 23W. I will just have to wait for Standard Horizon to send me the diagram, and then get a professional to re solder it, other web forums have mentioned how hard it is to solder the tiny wires.
When/if I get the diagram I will post it up here so it will be available for all to see.
thx
Mark.

Standard Marine Just got back to me, exactly as they said, within 48 hours and that included Memorial day too!
I think I have managed to attach it here.

I've used Standard Horizon gear for years because of their excellent customer service. I've also gotten very dependable service from their VHF radios, chart plotters and the Si-Tex radar array they use. Wiring all of the nmea 0183 data wires was where I really learned to appreciate their customer service help, I've saved all the schematic emails they sent for future use if needed.

I was perplexed with having to solder a lot of wires to a small connector until I saw the shop technician push the connector out and followed it with the wire and then soldered it and pulled the wire and connector back into place. Did I feel dumb. Not a chance, I was just happy they did it. But it can be done.
It wasn't SH by the way.

Mark, while SH was answering you, I took my old Ram mic off the boat and opened up the plug, so the microphone-side pinout is

1 - white
2 - green
3 - blue
5 - white (ish)
6 - black
7 - red
8 (center) - shield

Good luck!

I have pictures of the opened plug, in case.

Do you happen to have the link or a copy of the posting from 5-26-2015with the diagram for the wiring for a CMP23 RAM mic (standard Horizon). I have that mic "mounted" in my binnacle and the wire led down thru the engine compartment (with its intact plug) From the radio, I have the MIC wire plugged in but that cable has been cut. So I need to create an extension cable from the cut wires at the radio end, and probably have to cut the end off the microphone cable end as well. I wish I could find an extension cable but Stnd Horizon has none and I can't find it anywhere. They told me their current extension cable will not work

[Metalinker]

You didn't happen to keep any of the old wiring from the CMP 23W Ram Mic? I have that radio and extra mic but need an extension cable from the mic cable end to a cut end on the radio side. At some point during an engine rebuild the extension cable was removed and lost. I'm assuming the then radio side end had been cut and the wires from the extension crimped or soldered to the cut ends of the wire coming from the radio connector. It would be nice to replicate this if I could find an extension cable so one end would be factory.

I have a gx1280 with the CMP 23w ram. Bought it inexpensive, very inexpensive. Radio works great, ram not so much. Radio has mmsi from previous owner and SH will only say they may or may not be able to help but send the radio and $50 and we'll see. The ram, speaker works and you can hear the transmitt circut cut in but mic wont pick up sound. Had the mic replaced in the ram and tech says it is working properly but have rad somewhere that if you unplug or plug in when radio is pon you blow a fuse somewhere in the fadio body. Have never been able to get the fsdio apart so wondering if anyone has ever done this or run into this issue?
