Ivor,

Thanks for the pics, interestingly, i only get dashes where the position should be and no warning.

I will have to look at it again next week.

Richard

Yes, definitely correct port and wiring, like you, I'm stumped.

I've had a couple of weeks away from it so I will go down next week afresh and go through it again, one last time before sending the unit back to Trig to rule that out.

Thanks again
Ian

Thanks Peter

I think my next move is to get the units back to Trig.

Still concerned about the flashing red LED on the FTDI cable when Ian says it should be green for Tx.  Having said that it does send out the data.

Hi Ian

The flashing red concerned me too.  When I connected the PilotAware to a Computer with 2 FTDI leads the lead on the PilotAware flashed Red and the one on the Computer flashed Green and the NMEA data was sent across ok.

Pic of the Cable attached, it was ordered from Farnell.

Unfortunately I can't get to the 25 pin for a pic til next week but I am now 100% certain it is wired correctly.

Cheers
Ian

Hi Richard

I've checked the Traffic page and, No, Its not transmitting ADSB.

I don't think it will until it gets a valid position fix to the transponder.

I have tried with another TT21 Transponder which does have the very latest software and Its not getting the position data either.

Cheers
Ian

Hi Richard

No need to apologise, all suggestions gratefully received. 

Yes the head is up to date (1.12) The unit is at 2.7 (not 2.10) but it shouldn't affect this issue.  I think I will get it all back to Trig for an update and check anyway as I have run out of ideas.

GPS signal is good and the PilotAware is sending it to my iPad

Cheers
Ian

Still no Luck

I have completely redone the data wires to the TT21 with new wires and pins

Tested the output via crossover RS232 cable and PuTTY on my computer

But still no position reported on the TT21

Can someone confirm that it is just 2 pushes on the FN button to display the output when the transponder is in ALT mode, I just get dashes instead of numbers

Not sure where to go now

Hi Lee

Crossover test done and I can see the NMEA sentences going through.

back to check the Transponder wiring again............

Cheers

Thanks for all the replies everyone, Ive been without power up til now today so only just had a chance to read them.

Lee - I will hook up the cables and report back.

Peter - Yes, genuine cables from Farnell. Went thru the pins again this morning and definitely correct with good continuity all the way through.

Tony - Yes latest software on TT21

Alan - Yes, TT21 set to NMEA input, 9600 baud and uncertified GPS.

I will report back on the messages from the FTDI crossover hookup

Cheers
Ian

I have read through the forum and the many posts about this.  I think I have followed all the instructions and advice correctly but I cannot get position data on the Transponder.

The FTDI cable is connected on port 1 (top left ) I have confirmed this as changing port 1 data settings in the config page stops the RED LED flashing on the USB clear plug.

Orange wire on FTDI cable to pin 5 on TT21, Black wire to pin 4 (triple checked!!) The FTDI plug is flashing red so it appears to be sending data (I saw someone said it would flash green but mine only does that whilst booting).

Using recommended Anker cig lighter plug and heavy duty power cable.

I have tried a different FTDI cable, second PilotAware box and even another TT21, all to no avail

Latest software on both

Settings are NMEA, 9600 on Trig and Transponder Trig, 9600 on the PilotAware.

PilotAware are bought bridges on Pi b+ with a current licence.

Pilotaware Home page shows everything working and all green tabs and correct USB info.  I am getting position data on skydemon (ipad) and its showing ADS b traffic.

I am sure its something simple but I can't see what it is.

Any advice greatly appreciated
Ian

I think I get you are saying.

I understand there is No need for collisionaware with u-blox plugged into pilotaware

If I 'Go Flying' in sky demon with 'FLARM' I get pilotaware GPS data

If I 'Go Flying' in sky demon with 'Location Services' I get iPad GPS data

Or am I barking up the wrong tree?

Yes, connect via collision aware and Flarm.

Thanks for your reply, I used to think that but I gave been running my iPad with cellular data off for over a year and it still receives a GPS signal.

Maybe it's because there is no SIM card installed. I will try putting one in and leaving the data off.

Edited to add, still getting a GPS signal from the iPad with SIM card in and mobile data off.
