Interfaces and operation
The FX0-GMOD is equipped with an integrated three-port switch for connection with the
Ethernet network. Two RJ-45 sockets are available for the connection. The switch functio-
nality allows the FX0-GMOD to be used for connection to another Ethernet component (e.g.
connection to a notebook) without having to interrupt the Ethernet connection to the
network.
