First off CTS CT3003-ND is a Digi-key item number, not the actual part number. I knew what you were talking about though, bc i'm just that nerdy and memorized the the entire digi-key catalog and all the part numbers. (actually they just all end in "-ND")
288T232R162A1 is the actual CTS part number.
Anyway, this particular part is nothign more than a mechanical switch that contains no circuitty. Most encoders are a bit higher end than this and their working are a bit more complex. I'm too lazy to explain that though unless your really curious about it. As far as wiring it goes, its pretty straight forward. I'm not sure exectly which pin is which but basically you have a common pin and a bunch of other pins. Connect the common pin to the "+5v" pin of one of the digital inputs. Connect each of the rest of the pins to "sig" pins. For details on the pattern it outputs see:

The encoders you chose arn't really meant for this sort of use, but i guess they will work. They are actually meant for light duty human interface applications such as VCR controls and stuff liek that.
