Each board of the AMC13 with microTCA connectivity, "toungue 2" (T2) for the Spartan and "toungue 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, may be read from register 0x0 of either FPGA, and may be discovered by running a simple stand-alone python program.
