Problems with Galileo g2 working with navy PRFID

HI all,

I have a galileo gen 2 board and a navy parralax RFID which isnt running off the sample code provided on the arduino website.

http://playground.arduino.cc/Learning/PRFID

Im using the first piece of code.

I have it connected up correctly with the:

vcc to 5v
gnd to gnd
AENABLE to digital pin 2
Sout to rx digital pin 0

The red light on the Reader is staying on and it doesn't appear to be reading the tags.

Any help would be greatly appreciated.

Matt
