Serial Numbers

Each DCC has a unique serial number, which is set by cutting a set of traces on the PCB. These are located near the back of the board and marked "SN0" thru "SN7". SN0 is the lsb, and a cut jumper corresponds to a '1'.

To readout the serial number, start DCC2Tool.exe and enter the command vme/r 0x10. This will display an 8 digit hex value, where the first 4 digits are the serial number in hex. i.e.:

  > vme/r 0x10
  > Read 0x20050000  from offset 0x000010

This corresponds to S/N 2005. All boards should be marked with their serial numbers. Prototype boards have serial numbers 2001...200a.

• DCC2 occupies the right slot covered by the front panel, while the DCC1 occupies the left slot.
• All RJ-45 connectors are rotated 180 degrees. This is an unfortunate side-effect of mounting them on the main PC board.
• There is a new connector for Ethernet at the top. Do not plug TTS or TTC cables in here!
