Pinout
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.
