UniOP eTOP display and SLC 500

Does anyone have experience using the dual protocol feature on the Exor eTOP series displays? I currently have good communications between my eTOP 10B PLC port and my SEW Movidrive through a CA141 cable. I am having trouble getting my SLC 5/03 and the eTOP to communicate when using a CA12 cable plugged into the Printer/PC port on the eTOP.
