MCS2000 M3 Palm Mic Via Accessory Connector

[yaknamedjak]

Does anyone have any experience wiring a palm mic to an MCS2k via the bottom accessory connector?

I found this thread: MCS2000 Remote Mic Wiring - Batboard but I want to make sure that it's as easy as me figuring out how to wire the mic to those pins. I don't trust myself at all, I usually screw delicate stuff like this up.

TIA

What microphone are you wanting to use?

Sorry, one is the hmn4069d and one is the F version

They may have tinsel wire so you won't be able to solder the mic to the accy connector. You can use a female RJ45 jack and wire that to the Accy plug.

Here is my Motorola mic to ICOM HF radio adapter.

Gotcha, thanks very much. Do I have to do all the pins mentioned in the batlabs thread? Or do I just do all the wires from the mic and that's the end of it? Want to make sure I'm connecting the wires from the mic to the right pins on the connector.

Ground is pin 4
EMG is pin 9 and has to be connected back to GND pin 4
Mic LOW/Ground is pin 10
PTT is pin 21
TXAH (mic) is pin 23


I think you have to program one of the Accy pins for PTT.

Pinout for the Microphone Connector Note: Motorola numbers backwards from the RJ45 standard.

4 GND
5 MIC
6 PTT

So I got a custom cable made from Kurt Meltzer, a pleasure working with him and a great seller that I would recommend to all for cable and wiring needs for radios!

Works great.


Thanks

Link?

His eBay username is mre1032.

Here is the diagram for the cable Kurt manufactured, attached.

Following Kurt's diagram you can connect your palm mic to your MCS2000 accessory connector.


His cable is quality and to the length specs I asked for. My particular cable has an ignition sense lead, and the speaker out terminates in a female plug that allows me to plug right into my Motorola speaker. For the mic leads, he used a cable terminating in a male RJ45 connector. This allowed me to stick a RJ45 coupler on the end of that, which I plugged my palm mic into. I am beyond pleased. I will say that I paid half of what I paid for the MCS2000 itself, on eBay, just for the cable. But it's ok because I got the radio for cheap and the cable is of high manufacturing quality. I couldn't have made one so nice myself, but I'm sure some of you could.


Here is a photo of my use case: my mic clips are on the right, so the mics connect via accesory connector instead of over the console :

Do not forget to put 'dust covers' on the Mic jacks on the radio control heads.

I was just thinking about that..

Guess it doesn't get cheaper than this.. https://www.ebay.com/itm/291251328883
