Hi all! Just bought a MMKII and a Line6 Pod X second hand. There was no cable to connect the pedalboard to the Pod, so I found a standard cat5 (not crossed). I get power to th e board and the display says "FBV SB MKII", but there is no response when I push the buttons (no lights, and nothing happens on the pod). I connected the board to the PC with USB and all seems to be OK. Can the cable be the issue (have tested with two differnt cables).
