Automatic setting
The Ethernet interface of the CPU is set permanently to autosensing.
Note
In normal situations, the basic setting ensures trouble
free communication.
Autocrossing mechanism

connect the PC/PG. A crossover cable is not necessary.
Note
Connecting a switch
To connect a switch, that does not support the autocrossing mechanism, use a crossover
cable.
