Flaps position Potentiometer

[tomplatner]

Can anyone advise if the Dynon EMS 220 can accept a 0-5 volt signal that is generated from another device (in my case an ACI Flaps controller running on the aircraft 12 vDC system). The ACI flaps controller we have installed requires a 0-12 Vdc signal for flaps position. I would like to use a simple voltage divider resistor circuit to drop the same 0-12 signal (from the flaps position potentiometer) to the 0-5 vDC range needed for the EMS. I know I can install (2) separate potentiometers, but we are limited on room and it complicates the mechanical hookup. Thus the interest in a simple electronic solution. Always want to keep it simple.

What you propose should work, on the Type C inputs:
Pin 8 (Enhanced General Purpose Input 4) - Brown wire
Pin 22 (Enhanced General Purpose Input 2) - Violet / Yellow wire
Pin 23 (Enhanced General Purpose Input 3) - Violet / Green wire
Pin 31 (Enhanced General Purpose Input 13) - White / Orange wire

I used a Ray Allen that outputs 0-5V for flaps. I also have a linear activator that has a potentiometer I use for my cowl flap. It outputs 0-5V also. You need to do a calibration on a potentiometer but that is easy enough. My AFR (oxygen sensor) gauge outputs 0-5V and I had few problems adapting the sensor file so that Skyview can read the output from that. I think Skyview will pretty much read any 0-5V output and display the results on any widget on the screen. If you need to do calibration you may be limited to using flaps or trim gauges.
