Hi I have a FrSky D4R-ii on PPM. I tried to connect channel 2 to RSSI on MinimOSD micro but it doesn't work. Basically it takes away the overlay and gives out a dotted grid instead. Sometimes just take out the overlay and outputs nothing. I read that an RC filter is required as the D4R-ii RSSI output doesn't communicate directly with MinimOSD Micro. Wondering if anyone had success with this. Thanks in advance.

The RSSI from ch2 is a PWM signal i think you need a digital to analogue converter to convert it to a stable voltage level for MinimOSD to read it...
anyway I recommend using this method reading your RSSI.. no hardware changes, only software...
