Rear View of the Module
If your module is acng erracally, or not working at all, make sure that all cables on the back are
securely connected. The top 40-pin cable connects the front panel board to the FPGA board. The
le-hand 10-pin cable connects the module to the Doepfer format power supply. The -12V pin of
the cable (usually the one marked in red) must be oriented towards the boom of the module.
The two-wire (red-black in the photo above) provides the +5V power to the FPGA board. If it is
correctly connected you will see a blue LED light up on the FPGA board.
The silver connector directly above the +5V power connector on the FPGA board is a mini-B USB
connector, which is used to update the rmware on the FPGA (see appendix C for details).
