|
|
My audio panel (PS 8000) does not have a pin for "Mic Key Lo" but my com
radio (Garmin 430W) requires one. The Garmin install manual says to use
a connection to the audio panel ground lug. "Mic Audio Hi and Mic Audio
Lo" are in a 2 conductor shielded cable. The Garmin shows a 3 conductor
cable with one wire connected to the ground lug on the audio panel .The
shield is grounded at the audio panel. Is there any reason I can't
connect a wire to the radio end of the shield and use it for the "Mic
Key Lo" input on the 430? It would save me from having to redo the cable
and I can't think of any reason it wouldn't work.

John, you simply tie (tee) into the Com audio low. Use the same method
|
you use for tying the shields together ala' BK's web site if you like.
Worked fine for me with a 430W and a different PSE audio panel.
