Hello Alan and Thank you again. We are getting there.
I've already done a bunch of the measurements with a voltmeter and know what the ET-134 outputs. The 126 and the 134 for have the same pinout but what I need to determine is what signals need to be sent and/or switches closed to get on the vector 300 controller operate correctly.
From the ET 134:
Pin 1 signal ground (Reads continuous 0.7V against common ground regardless of throttle position)
Pin 2 requires +48v (13V to 52 V - tested down to 10V)
Pin 3 produces +52V against common (or signal) ground when dial is spun in reverse direction, 0V in forward direction
Pin 4 produces +52V against common (or signal) ground when dial is spun in forward direction, 0V in reverse direction
Pin 7 is common ground - of 48V
Pin 8 produces variable + 0-5V against common ground in either forwards or reverse depending on the amount of dial rotation (Max 5.3V stated but I haven't seen that high of a value yet, My unit maxes out at 5.02V for a second then stabilizes at 5.0V)
So now I know how to wire everything except for somehow I need to close the switch between Brown and Black for reverse.
Regards,
Charles
