Soldered up the serial cable and tested it - works fine
As you see on picture that Paul posted (on controller from access end):
Ctl = controller, 3 pin keyed connector with male pins on 0.1 inch spacing. Cable uses female with 3 pin header on 0.1 inch spacing
PC = 9 pin male on usb to serial converter, 9 pin D-sub female on cable
Ctl TX = Left = white = 2 = PC RX
Ctl RX = Mid = red = 3 = PC TX
Ctl GND = Right = Black = 5 = PC GND
Soldered up the potentiometer to the 3 pin header (not a keyed connector since I don't have one)
5V on left of header -> 4K7 resistor -> 80K pot -> 10K resistor -> 0V in middle of header
throttle signal on right of header swings from 0.48V to 4.52V
Note to solder this together
orang - 4k7 - orange
white - 10k - white
blu - 0ohm - blu
That took a *LOT* longer than it should have. No pictures - that will have to do for tonight.
So the encoder interface is pushed to next time!
