GM300 - Rigblaster M8 - Echolink Node

[KB5AKO]

Hello,

I have a GM300 that I want to interface with a Rigblaster M8 to use as an Echolink node. The radio will xmit with audio whenever the hand mic is plugged into the mic jack. However, it will not xmit when I plug the RJ-45 connector from the Rigblaster to the mic connector on the front of the radio and execute an ID command from within the Echolink software.

The jumpers in the Rigblaster are set as follows:

1,2,3,7,8, and GND TIE are shunted.

Input Side:

4 = PTT GND
5 = MIC
6 = PTT

Output Side:

4 = PTT GND
5 = MIC
6 = PTT

The MIC GND pins are both open.

I tried to examine the logic board programming with
RSS version R05.00.00 but can't see any selection for
the 16 pin logic board. Is that unavailable?

The model # of my radio is M33GMC20D2AA.

Any help will be greatly appreciated. Thanks!
