My FR4000 repeater is running on Revision 1.2 (the programming software is 1.4) and I was able to get the Firmware to update it to v1.6 (EX2712A-6) but now I see I need the OPC-1211 Flash Upgrade cable that plugs into the Logic board (J-12) Does anyone have any idea where to find that cable or even the pin-out where maybe I can make my own??
