Ive installed a Skyview system in My LongEZ. I have an error message saying Xponder 261 Not installed. I checked PNs and it says on my transponder Trig TT22. I ordered the system through Spruce and selected Xponder 261 in my order. Are these transponders Identical?
IS xponder 261 identical to TrigTT22

A picture of the Transponder manufacturers tag on the Txpdr will help solve the issue.
FYI - the TT22 is a Class 1 unit like the Dynon 261 however although they are both built by Trig (now owned by Dynon) the TT22 is not compatible. I believe there are software issues &, unlike the TT22, the Dynon does not nave the inbuilt encoder.
note : The Dynon 261 does not need an inbuilt encoder due to that function being supplied via the SV EFIS.

jakej answered your question, did he not?
Im not sure what you mean. But I spoke with Dynon today, they are, in fact, one in the same if the Dynon sticker is on the transponder. Mine has it so it is a 261. The warning came from me scrolling one too many in the serial setup. I had selected Xponder-262...... All fixed now.

Now *I'm* confused. Your box says TT22, and I thought that was equivalent to a Dynon 262. No matter...if you have what you need for your location and aircraft performance, that's great!

Just an update - FYI, if the transponders don’t have a Dynon label on them they are the Trig only units which include the encoder. The Dynon versions don’t have an encoder, and rely on their EFIS with inbuilt encoder, & have both labels ie Trig & Dynon On their units.
As I understand it, Trig messed up the numbering of their TT21/ TT22 units during certification & were unable to change them back.
So they are stuck with -
TT22 is a Class 1 Txpdr - which is similar to the tagged Dynon 261. (higher power & meets IFR specs)
TT21 is a class 2 Txpdr - which is similar to the tagged Dynon 262. ( lower power).

Wow, that's some seriously bad configuration management LOL! I've seen plenty of wires and signals swapped (A-B, 0-1, On-Off, etc.)...but never and entire product line! HA!

But that was not what the OP asked.
OTOH, knowing exactly what the different models are may help anyone purchasing old stock or via adverts etc.
Btw - the Dynon/Trig Txpdr 261/262 has a Dynon label at the connector end & a Trig label at the other end. (The OP downloaded only 1 x picture - both ends pics are needed to properly identify the units).
