Reset an ME or Wi-ME back to factory defaults while it's on the Digi Prototype board

With the Digi powered off connect pins 2 & 3  of the P12 pin header.  Then power the Digi up and wait for about a minute.  You can then power the device off, remove the connection from pins 2 & 3 and then power it back up.  It should be back to factory defaults.
