Hello
I have the ping200xr on telem 2 slot on my orange cube plus. I Have no issues gurning it off on the callsignor the sqwak code through a rs232 to ttl adapter.
Then the ping200 is set to internal on alt. It reads tge usual negative number (i dont have a calibratikn tool yet) and during flight it reads correct on altitude gained but not the acual number. Gps on the ping works just fine.
When set to external though it reads 0ft and does not change. I had followed the steps in the manual to tge best of my ablity bit im kinda scratching my head on this one since it communicats just fine all the other cmds to turn to standby, On or Alt modes.
Help appreciated!
