Problem programming M120 VHF

[sailor]

Hello,

I have a 2 Channel VHF M120 that I previously programmed and I'm sure I used the GM300 Ver 5.0 RSS. I read the radio fine but I'm now trying to set the acc pin config and don't have the F9 other accessory option in the RSS under radio-wide config. It's been so long I don't know what I'm missing!

Can anyone help here? Is this the wrong version? I thought maybe t was the radmbl...

I don't believe the 2 channel version had programmable pins. It has been a while since I worked on one of them but I think that is the case.

L.E.

Oh that's pretty interesting. I didn't know that. So what are the defaults for the accessory connector? Are the pins active?

My main concern is pin 8 CSQ Detect. I need active low for COR.

I am pretty sure that all the radios with 8 channels or less were not programmable for the acc pins.
The 16 ch and up were programmable for 6 pins.
Most of the pins you would need for basic stuff are the same in either "versions".
Look on the Batlabs main site or maybe repeater-builder for pretty good explanations.
Basically, mic, RX audio out, PTT and a COS/PL detect (pin 4) are all available.
You just can't program for as many fancy options.

The M120 does not normally show the 'F9 - other accessory' option in the RSS, however there is a work around as per this thread:

It involves using the 'repeater mode' of the GM300 RSS to get access to pin 8 of the M120 for COR.
