Hi all,
I've built several quadcopters from scratch using APM 2.6. This is my first Pixhawk build.
I have a Pixhawk 1 and I'm trying to connect a set of 3DR telemetry radios. I know the radios work because I've tested them in another copter. I also tested the DF13 cable and its good. When I plug the radio into Telem 1 or 2, it doesn't light up. I checked the volts on pins 1 and 6 of Telem 1 and 2 and I'm only getting 0.24v. Shouldn't I be getting 5v on both ports?
When I power the Pixhawk it makes the normal startup sound, then there is the flashing yellow light because I haven't connected the external GPS/compass yet. It has Arducopter 3.4.5 loaded.
Any ideas? What other tests can I perform? Am I missing something?
thanks
