Is it possible to control a Jaguar with a potentiometer?

[dtengineering]

I was wondering if it might not be possible to set the Jag to Analog Position Control Mode using an RS-232 or CAN connection, telling it to head for the 1.5V position. Then set only a proportional response, no I or D.

As you swing the pot to one side the motor should move in one direction, with increasing power relative to the "error" in the Pot. Swing it the other way and the motor should turn in the other direction.

Not that there is anything wrong with the other ways, but is there a reason this wouldn't work? I haven't played with the Jags for years, so I'm just working from the manual here...

P.S. Not that I don't use 555 timer circuits, but I'd probably be tempted to use a PIC or Arduino to generate the serial code for the Jag, but they could also generate PWM code quite easily. A 16f88 or similar would be a one chip solution... easily programmable in Great Cow Graphical Basic, using a PICKIT2 or PICKIT3 programmer and a breadboard.
