Help with bricked GoFlex Home pin numbers (4 replies)

I have all the supplies to rescue my GFH with a serial cable. However, my pin locations appear to be different than what I have been able to find on various forums. Can anyone help me identify the Tx, Rx and Ground for my particular board? The board itself is stamped with:
EHDUL4 7D28UL44001R1
REV. 01

and the pins are arranged:

54321
678910

Thanks much for any help!
