RSSI Hookup with DF4RII in stock Iris

Can the PWM RSSI output on channel 2 be hooked up to the PixHawk? Is it not connected in the shipped versions of the Iris for a reason?

I have also been trying to get RC RSSI working both with my Iris and another Pixhawk quad that is using the DC analog output from a dragonlink receiver. Neither are working for me.

Does anyone have RC RSSI funcational using a pixhawk? I can get telemetery RSSI on my OSD and MP HUD, but not the RC signal strength, which is more critical!
