I am build a new 3DR copter and am having some trouble/questions connecting the RC electronics.
I have a new Spektrum DX8 radio and AR8000 receiver. I have connected the APM to the receiver using 6 - 3 wire connectors.
With the latest version of Mission planner I can connect, update firmwar, and see real-time GPS and other sensor activity.
I do not however see any radio input. The receiver has been bound to the radio, and the bind light is solid.
I have attached a picture. I do not have the custom cable mentioned on the wiki - but it seems to suggest this way will work also.
Do I have something wired wrong? Backwards? Any ideas?
I think the manual does not specify because it is receiver-specific. All of my futaba receivers are signal on top, +5vcc in the middle, and ground on the bottom, with "B" (input power) on the highest channel. As the manual has no idea which receiver you might have, it only shows the connection logically.
Thanks Mike and Matthew - you were right, the Spektrum receiver has the signal on the bottm (5V in the middle, GND on top) - nothing on the pinouts inthe Spektrum manual
How are you testing radio input? Just moving the throttle, or via MP->Configuration-> Settings -> Radio? or via CLI test->radio?
Do you have the APM powered from the servo rail, or only via USB?
Have you binded the radio to the receiver while plugged into the APM ? It will not work if you bound to the receiver without the APM. See this thread http://www.diydrones.com/forum/topics/spektrum-dx8-and-ar8000?xg_so...
I could not rebind yesterday, but once I got the input wires properly connected, I was able to rebind and now have successful communication between the APM and the RC receiver! Thanks all.
Hopefully motors come today and then more testing :)
