What is this port?

[Drew_Wagner]

What is the port labeled 12 volt in the attached screenshot? Is that for panel powered headset? There is one on both sides.

It looks like a headset Lemo plug.

Looks like a 12v plug for a headset

Ok so if I get a headset with lemon plug that will power the headset and provide audio? Please excuse my ignorance on this! that was my initial thought but I couldn't get a good idea if the size and form factor of a lemo plug online. Thanks for the info.

[Drew_Wagner]

Autocorrect....Lemo, not lemon

Look up what a Lemo plug looks like and compare to what you have.

I get the feeling if you don't know, You may get a surprise.  Plugging in an expensive headset without checking +/- could be bad.

That looks on the internet like an ordinary plug that has been used.  Lemo plugs have been built with additional equipment protection into them...

You may find your wiring diagram has been updated to reflect this change.

Good luck.

Good idea. I'll put the voltmeter to it and also check the logs to see if I can find any details.

That's not a lemo plug, but looks like what the Telex Headsets used for panel power.

I can not see enough detail in your drawing, but David Clark ENC headsets hav a panel mount plug that provides current and audio connections.  It may be one of those/

Get a really close and clear picture of the inner part of the port.

Looks like microphone port, I think that was where it was in my 201.

It's hard to tell from the picture, but it looks like there is a centre pin in there.

With a center pin it is likely a simple 12V power plug for some portable device. There are many round 12V connectors out there... If it were me, I'd consider putting a USB power jack in that location instead.

Correct..I am guessing "n size "center pole positive non aviation approved power plug.

[thinwing]

Make sure it's fused ,Chinese made ,radio shack plugs were 1.99 each and had solder lugs on the back.Center insulator was low temp nylon that melts easily when soldering.My opinion...if it's not fused,it's a fire hazard

Here it is close up. Definitley not LEMO.

[thinwing]

M size

[Drew_Wagner]

Yeah I don't think I will be keeping those at annual...I wonder if these could be causing the radio noise I have found impossible to troubleshoot?

I was thinking about installing that Mid Continent digital clock with dual USB. Anyone with a PIREP?

[carusoam]

Yes, Drew. There are pireps for that.  About three threads...
