The PDM card may set to the old ID value of 7 but that it should be set to 9 for SAM14 firmware. There is a jumper area, two rows of four pins, near the module back-plane connector, with pairs numbered 60, 61, 62, 63. The numbers may not be clearly visible where jumpers are fitted. Four jumpers are possible, each from one pin in one row to the corresponding pin in the other row. Fit a jumper across the pair at 60 and another across the pair at 63.
