Posted by jean huynh on January 19, 2014 at 11:13am

got my pixhawk and tried to install it on my quad that used fly with apm 2.5, i have question on 3dr radio telemetry connect, my 915mhz which only 5pins connect and also my apm 2.5 telemetrry port.

now i move the telemetry radio to pixhawk and found out its 6 pín connect?? anyone know the pins mâp out on pixhawk telemetry port ,, and how do connect my 915mhz air module radio to the pixhawk?. i hope i do not have to buy a new radio to use with pixhawk

3dr responded and I just changed the telemetry port to 2 from 1 and it powered up... I have since had to stop the Y6 build until today to finish up another Arducopter build, as I ran into a few faulty parts. That one is a dead cat design. Madien today, and it balanced enough without and setting changes and in a wind of 15knots so very impressed with the Arducopter soft so far...

Seems I have issues with the battery info as the levels seem random of how much is left... Sure it is just tuning but it is getting good..
Also 3drobotics sure jumped to help when their was bad hardware, they quickly remedied the problem replaced the problem parts and I should have it in the air tomorrow

ok this looked like the best place to put this...

I have a new pixhawk and I am connecting the 3dr radio.. when powered I do not see a light when connected to the pixhawk but I do see it when I connect it to the usb computer... is this correct? do I have something wrong?

Also having a issue connecting to the radio when connected to the computer... it just flashes green and says it installs the driver correctly but I cannot load the radio settings...

  I have had this problem before. The simple fixes I know of are:
  
  1. Make sure the port and baud are correct. I think it shouls be 57600 or something that looks like that.
  
  2. Give the comp a chance to download the drivers.
  
  3. Try connecting via usb cable to the pixhawk to make sure things work fine.
  
  4. It won't work if the little micro SD card is removed or not installed correctly.
  
  5. Make sure the antennas are all screwed on tightly.

Hi Jean, I have the same problem as you, I have old 3dr radios and a new Pixhawk.
Did you manage to get the pin mapping to make up the cable. Specifically what the pin In map is on the Pixhawk ?
