Many thanks for your replies. Somehow I hadn't spotted the second level menu on the Trig and the Aux level was at zero. Hazards of an online rather than a printed manual I suppose! Test signal is coming through fine now but I've yet to check whether it's loud enough in flight so that mixer may yet come in handy.

Technical Support / Audio output connections

« on: November 10, 2017, 11:14:04 pm »

I know this subject has been touched on in some old threads but...

I have connected my PAW audio output following the advice in the various posts on the subject here but I am still not getting any audio in my headset. I am connecting directly to the auxiliary audio input on my Trig TY96 radio.

I am using a TRS plug in the PAW TRRS socket. I have wired T and R (L and R signals) together to pin 14 (auxiliary audio input) on my Trig and S to my avionics ground. Trig assure me this should work but I am getting nothing.

I know the PAW is actually outputting the audio correctly because if I simply connect the PAW to the music input socket of my intercom using a cable with a 3.5mm plug on each end and use the test facility on the config page, I hear the test message. However I don’t want to use this socket and I don’t want trailing wires all over the cockpit so I really do want to connect directly into the radio if possible.

Is there some incompatibility in signal strength or whatever between the PAW output and the input that the Trig needs to receive via its auxiliary input perhaps? Or have I made some other error?

Any suggestions gratefully received.

Richard.

Technical Support / Re: Verification of ADS-B out on Traffic page

Thanks, Lee. I have repeated the experiment and all is behaving correctly. False alarm!

However, I do notice that, although the P in the mode column is rock solid, the CSA is a bit intermittent, mostly visible but disappearing for a few seconds every 20 secs or so. Is that normal or does it suggest a problem?

If anyone is familiar with the Funke TRT800A transponder, is it possible to display, perhaps in test mode, the actual position being sent by the GPS source?

Thanks,

Richard.

My first post to this forum so I hope this gets picked up as it's rather an old thread, however one directly relevant to my question.

What exactly does the mode column in the traffic screen tell me? I ask because I have recently connected my PAW unit to my Funke TRT800A transponder to enable ADSB-out and have successfully used another PAW unit to check the transponder output. It does indeed show CSAP against my registration on the top line. However, if I switch my own PAW (the GPS position source) off, and even pull out the USB plug sending the data to the transponder, the A still remains in the mode column.

Does the A simply mean the transponder is squittering with or without a valid position? If so, then how can I truly check the ADSB-out functionality?

Bearing in mind Lee's July 15th 2016 post, to which this is a reply, it could be that I simply didn't wait long enough to see the A disappear. I will check again but I'm sure I waited a lot more than 10 secs!

Thanks,

Richard.
