The REF 542plus has a default IP address. To configure the new IP address
the operator has to configure the IP address before to connect the
REF 542plus to the network. This in order to avoid address conflicts between
the default IP address and IP addresses already configured in the Ethernet
network. The REF is fully TCP/IP standard compatible.

Configuration of the IP address
REF 542plus determines only the last two numbers as an IP address. In this
case 2 means the device has the number 2 in its sub network. It results in that
a maximum of 254 devices per subnet are possible.
The IP address with the number 10.41.75.255 determines a
broadcast address. It is not allowed to configure any addresses
with this end figure, because all the users above the subnet mask
range are then addressed.
6.4.4.
Subnet mask
The subnet mask can be set as it is needed, but only the 3rd number is
determined.
