No Power on Telemetry port

Posted by Andi on July 21, 2015 at 12:18pm

Hey guys,

i'm currently facing a problem i don't really understand. The Telemetry module connected to APM don't get power. The module itself is ok, tested on PC:

The APM 2.5 is powered via the 3dr Power module and everything is working fine, besides that the module is completely dead. Isn't the 5v rail powering the APM the same which should go to the telemetry port?

any idea what i could try? maybe replacing the power module?

regards

Andi

    I'd guess it was a bent pin on the Radio connector or the APM 2.5.

      unfortunatly it's not that easy, all pins are ok....

        If it works when using the USB connection and not the 6 pin DF13 connection I'm guessing its a power up issue. I'd guess finds or cable as the first problems to look at. After that it gets more complicated

          i will check the cable later, but i thought i tested it already, was ok. However, if it is not the cable what could it be? Power module? Has it seperate circuits for the APM itself and the peripherals?
