Step 5Wire up the serial header
The header on the board is designed to go to an IDC 9 way ribbon cable, and then to a D9 male plug. The only trick is that the 10 way header is designed to take 10 way ribbon cable. If you use 9 way cable there is a gap for the missing wire. I've taken a closeup to help clarify this. If you wire it up right then pin 1 on the board goes to pin1 on the D9. Pin 5 on the D9 should connect to earth on the board. If those two are connected the rest of the wires will be ok too.
Wire 1 is on the left of both views of the ribbon cable. You could use ribbon cable with colours if you like.
The messy stuff on the IDC plug is hot melt glue. Probably not necessary but it makes things a bit stronger.
