I am writing this post in English because it might be of interest for user Tadango who designed the FrSky adapter.
I am building my first large aircraft and decided to buy a PowerBox Mercury SRS with GPS. I fly with FrSky and will keep my radio. Due to the lack of FrSky telemetry support I built the Ardunio Telemetry Adapter of user Tadango. Today I powered everything up on my workbench, and everything including telemetry like voltage of both packs are working fine. Only issue is the GPS, where I am not getting any data via telemetry, the items such as coords, altitude, etc. are available, but all remain zero.
The GPS II first blinks and on the display it says "GPS: Search". After a while the LED turns solid and the display says "GPS: Ok". So I believe the GPS is technically working. The GPS is connected to the "GPS" port of the PowerBox Mercury SRS, on the side. I then consulted the manual and now I am confused.
- The GPSII manual states I need to connect the GPS to the receiver. Is that for other PowerBoxes without GPS port?
- The GPSII manual states I would need to configure the GPSII according to the telemetry protocol in use, which in my case (if wired to the Rx) would be SBUS. Am I correct that it should work out of the box when connected directly to the PowerBox?
- The GPSII manual refers to an included Y-cable. I did not get a Y-cable with the "PowerBox Mercury SRS incl. GPS", just a simple patch cable which I used to connect the GPS to the PowerBox.
- Furthermore is there a description of all telemetry values (5110, etc.) available? I know how to code, but it seems I am getting a few telemetry values which are not yet covered and I'd like to include them all.
Nebenbei: Stimmt es, dass weder im Handbuch, der PowerBox selbst noch sonstwo steht, wie rum die Servostecker eingesteckt werden müssen? Anhand von Bildern im Internet habe ich es herausgefunden, aber der Ansatz ist nicht wirklich state-of-the-art.
Thanks a lot
