3.2Pinout

Connector for Industrial Ethernet

On the front panel of the CP 343-1, there is a 15-pin sub D female connector with a sliding locking mechanism for connecting a transceiver cable. The signals of an ITP interface can also be applied to this connector (switchover by relay).

For operation via the AUI interface, use the 727-1 transceiver cable. A special SIMATIC NET ITP cable must be used when operating via the ITP interface.
