There is another connection ...
Wondering if someone can explain to me...
The portable ADS-B receivers generally function via Bluetooth or WiFi to a display. Most transponders, if not all, need a hardwired suppression line input for an ADS-B installation. Is this possible with the portables?
Specifically, I have the Trig TT22 transponder and was looking at the Dual XGPS170 UAT. The display is GRT HXr which has bluetooth capability.
The DUAL XGPS170 ADS-B receiver can supply the data to the GRT HXr via **USB**. You will want to get a powered USB hub so that you have enough ports for other Bluetooth stuff and your memory stick. The hub is *required* for the SX series.
Now, when you connect via the USB port, the HXr will recognize the DUAL. You will need to have USB ADS-B turned "ON" via setup of the HXr.
You will also need to add your "N" number and the OCTAL registration number from the FAA (converted to HEX) to the HXr in setup. The Trig TT22 will have this info as well.
When the Trig "squits" your info (n-number, registration number, altitude, speed etc) and that info get broadcast to the aerial world, you HXr will say "Oh!, that me. I don't need to put that on the screen nor do I have a traffic alert!"
Bluetooth on the DUAL is used to connect to you iPad or Android tablet or phone running your favorite compatible app.
Bluetooth on the GRT is used to connect to your Android tablet or phone running the GRT app.
Hope this helps. More info is on the GRT site.
Feel free to "holler" if there are further questions as I am the one who did initial field test of this combination.

p.s. The same process works for other compatible receivers e.g. the iLevil and the SkyRadar
