NOTICE
The device supports a transmission rate of 100 Mbit/s in full duplex mode as well as auto-cross-
over.
NOTICE
The entire interconnection cable must be shielded.
The shielding connection must be at the same potential at both ends of the data line. This
serves to prevent potential equalization currents over the shield and possible interference cou-
pling through compensating currents.
Ä Use at least a CAT 5 cable for the connection.
