EPM Pixhawk flight computer aux port 1 not working

[ctech]

Hello Andreas,

I received my the EPM I had on order yesterday... Thanks.

Now – I’m trying to get this working on my quad copter build using the
3DR Pixhawk flight controller – I have tried connecting the aux port 1
on the pixhawk to the EPM as per the diagram provided but when I cycle
my PWM to 1925, it doesn’t seem to activate the magnet. If I hit the
button on the EPM it grabs and if I hit it again it releases.

Do you have any specific links on how to use this device with the
Pixhawk and what configuration parameters in Mission Planner need to
be setup to make this work? I have followed the wiki pages at
http://copter.ardupilot.com/wiki/common-electro-permanent-magnet-gripper/
but it is referencing only the old APM flightboard and not the new
Pixhawk. Even so, I tried most of the steps listed, but nothing out
of the Aux ports of the pixhawk is activating the magnet…

Do you have any specific instructions for getting this working with the Pixhawk?

Any help would be appreciated…
Thanks,
Marco
