What is the default IP address of a TSXETG30xx module?

The default IP address of the TSXETG30xx modules is 10.10.xx.xx where the last 2 octets are a conversion of the last 2 octets of the MAC address.
For example if your MAC address was 00.80.F4.03.51.96 you would need to convert the Hex 51.96 to a Decimal 81.150.

So the default IP address would be 10.10.81.150
