Connecting to LAN

When connecting an IR-ETH interface module with the UTP option, use either a
straight cable or a cross cable for the LAN connection. Use a cross cable when
connecting to a port that does not implement the crossover function internally.
Otherwise, use a straight cable.

Hubs usually do implement the crossover function internally, while network
interface cards and other devices do not.
