There is no standard for running a RS232 serial connection over RJ45 connectors like there is for DB-25 and DB-9 connectors. I wish there were, but.... We just make our own cables and ends. Using flat satin cable, putting the RJ45 ends on is trivial, and Comtrol's pin out allows a cross over cable to be built by putting the RJ45 connector on one end of the cable on backwards.
