AX3500 with Game Port Joystick

Hey guys,
I am taking over a project where the previous team used your AX3500 motor controller. I have a joystick that uses the game port (same connector as on the AX3500) and I was wondering if it was plug and play. I don't see anything in the documentation for this. I don't want to ruin the controller so can someone confirm or deny this?
Thank you,
Alex

Even though the connector is the same, the pin out is totally different.

Additionally, the pots are wired differently inside the joystick than what is required by the controller.

Refer to the manual for details on pinout and pot wiring.
