The numbering of the connector is from left to right when looking from the edge of the board at the pins of the header.

Hardware design file notes:

All designs up until version 1.0 of Floss-JTAG were designed in Cadsoft EAGLE. To view the files you will need to install Eagle. Most of the designs are 4layer, this means that you will need a payed version of the software to edit the inner layers of the board.
