Re: ADS-B+ compatibility

"Garmin ADS-B" is correct for both the original ADS-B and ADS-B+ formats.
If you wired the ADS-B+ output to pin 5 on the adapter, the adapter should detect the GPS data. Your "External GPS Communication: No" line says the adapter is not seeing any data on its pin 5 at 9600 baud. If you wired directly to the TT22 pin 5, bypassing the adapter, then the adapter can't detect it. It doesn't matter how you wire it for the TT22 to work.
The "GPS Position" line is a report of the current position from the TT22. If the 430W has a position but the TT22 doesn't report one here, then the TT22 does not see or does not understand the data.
Check the "Transponder Versions" line. The number after "SW" needs to be 2.7 or newer (note a version like 2.10 is newer than 2.9) to support ADS-B+. If you have SW 2.4 or older you need an update of the remote TT22 box. Most TT22 units shipped in 2015 or earlier have 2.4 or older and need to be updated.
