10 Prototype boards with red front panels were manufactured in early 2009. These boards are not compatible with the production boards because they have a smaller FPGA. The production front panels are marked "DCC2" and are black.

Boards are numbered in decimal starting with 2001 for the first prototype up to a maximum possible number of 2255. The first digit is always '2'. The other three digits represent the decimal equivalent of the binary value set by cutting jumpers on the PCB.
