DMD w/o "dmdcon"

Hello, I recently purchased a 16x32 DMD similar to the one found at : I'm trying to connect it to an Arduino Nano but I don't have the shield, "dmdcon", that comes with the freetronics DMD. I've studied the schematic for the dmdcon, found at the bottom of the link above, and have two questions: 1) Does it do anything besides rearrange the pins from the ribbon cable to plug directly into the Arduino? 2) In the schematic, where do the "C", "G", and "D" pins go? More specifically what pins do they connect to on the Arduino?

Please let me know if there's any more information you need, and thank you for your time.

CDG appear to be un-connected pads on the conn board.
