I have purchased a 30RJ45SMA5SH,PK socket which will provide a future c-bus point possibly for remote amp. My question is what is the wiring for this. On the back it has colour code for 568a and 568b but I have not seen any diagrams in the c-bus instructions for the socket, only the plug, and I am unsure how the RJ45 pins 1 to 8 in a row on the plug, map to the 1-4 top and 1-4 bottom in the socket. Does anyone know of a link to a picture, or is it just 568a or b?
