Sorry to bother you again but I’m slightly confused now. The diagram on http://www.gumstix.org/tikiwiki/tiki-index.php?page=I/O shows pin 4 being offset to the right when 3 pins are at the top and 2 pins are on the bottom…This is not the case for me. My pin 4 is offset to the left. So basically from the diagram my pin 4 is nearer my pin 5. I do not get a signal on pin 5 I get it on pin 1 and pin 3. Does this mean the cable could be faulty not the STUART?

The pinout on the cable is at http://www.gumstix.org/tikiwiki/tiki-index.php?page=I/O
The pin you need to check is pin 5 on the minidin connector, which is middle row, on the right as you look at it. If that pin has voltage (either -ve or +ve) relative to the middle pin (pin 4), then the problem is 90% likely on the STUART board. Don't bother trying to figure out where the problem is on the STUART, we'll just ship you a new one. I can't find you in our customer DB though -- let me know who the original customer was in the next hour and a half, or the order number and we'll send one off today.
