Thanks mlord. Serial Cable turned up but unit doesn't show up in emplode. Not 100% sure where to go next.

Possible area's I can try are:

Replace serial cable (I can probably test this one to ensure the pins are correct)
Try a different PC
Buy a different USB to RS232 Cable

If no luck then I can get figure out how to get Win32 VM working and try USB.

assumptions I am making:
USB Port settings don't matter?
Emplode is working
