Phidgets 8/8/8 interface

I have just bought a Phidgets 8/8/8 interface card for my cockpit for the sole purpose of controlling HDG/CRS/QNH knobs. Is this a semi straight forward thing to achieve.? If so could someone advise on the best type/value pot to purchase and what software to drive the card to interface with FSUIPC. Windows 7 - 64bit. FSX.I am using the LED64 Phidgets card to drive LED's with some degree of success, using Phil's software and was hoping that using the 8/8/8 card will be as easy to interface.Any help is very welcome as always.Matthew

Those functions use encoders, not pots. I don't think you can connect those to a Phidgets 8/8/8, you need this :

I could be wrong, though.

There are however much cheaper alternatives, like the Bodnar BU0386X
