Due to a little mixup, our output ports don't mix the port number. So the LED's on the board are in the correct order. If you turn on port #1 from the software, LED #1 will light. Turn on port #2 from the software, LED #2 will light. However the pin directly across from the LED wont necessarily turn on. So if you turn on port #1, pin #5 will turn on as shown in the table below. It is not supposed to be like this, but we made a boo-boo, so that is how it is. This only applies to version 3 boards.
