Adam Posted May 15, 2012 Report Share Posted May 15, 2012 New Plane, CTLS, One of the Lemo Plugs (Pilot Side) has an open mic wire. When you press the push to talk on the stick and talk the audio you speak does not transmit nor do you hear the feedback in the ear. You do hear the radio and can converse with co-pilot. Headsets plugged into the regular portable jacks work just fine. There appears to be an open mic wire to the pilot side lemo. Field mechanic can check for me but it's not clear to us in the wiring schematics where the lemo plug wiring goes from the back hat shelf. Can anyone articulate where the wiring from the lemo on the pilot side goes? Is it running direct to the PM3000? (If so what input pins?) Is it paralleling off the standard plugs? (if so where?). The schematic page that shows the PM 3000 pin inputs does not state where the Lemo's are supposed to connect (Are they in headset 3 or 4 position? Are they parallel to headset 1 or 2?) I do not see the word Lemo anywhere in the drawings. Hard to check continuity of the lines with no schematic reference. Link to comment Share on other sites More sharing options...
