I have a brand new APM 2.5 all loaded and working great according to the info displayed in Mission Planner. All the RC, inputs and outputs all move on the screen as they should.
Yet no matter how many times I re-calibrate my ESCs they still beep every 2 second indicating an abnormal input. The ESCs work fine plugged directly into the RC receiver but when plugged into the APM it just beeps and does nothing.
How can I check the outputs from the APM ???
I do have access to some high end electrical test gear (scopes and stuff)
I have migrated from a Cirus AIOP 2 thinking this was a simple plug and play board ......AHHHHHH
Any advice would be so very welcome right now

Hi
you can always connect mission planner and have a look at the STATUS screen, to see the exact PWM values both in AND out of the APM.
For a start, Re-do your Radio calibration.
Also have a look at the connector from the PDB to the APM, carrying the ESC signals. Make sure you have the 2-wire connector in too( for common ground reference), the Jumper1 removed, and the connector on the correct pins. that one is easy to get wrong.
