Each board of the AMC13 with microTCA connectivity, "tongue 2" (T2) for the Spartan and "tongue 1" (T1) for the Virtex has its own IP address. The IP address (192.168.1.xxx) is derived from the AMC13 serial number as follows:

• Spartan xxx = 254 - 2*(serial no.)
• Virtex xxx = 255 - 2*(serial no.) = (Spartan xxx) + 1

The serial number is etched on the front of the card. It can be discovered using the python program 'find_ver_serial_no.py' or by reading the upper eight bits from register 0x0 on either chip
