other optical line is used transmit data from device II to device I, for
full-duplex transmission.
All you need to remember is to connect the Tx (transmit) port of device I to
the Rx (receive) port of device II, and the Rx (receive) port of device I to the
Tx (transmit) port of device II.

Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power sources.
If one power source fails, the other live source acts as a backup, and
automatically supplies all of the Media Converter’s power needs.
Alarm Contact
Weidmüller Media Converter has one Alarm Contact located on the top panel.
For detailed instructions on how to connect the Alarm Contact power wires to
the two middle contacts of the 6-contact terminal block connector, see the
“Wiring the Alarm Contact” section above. A typical scenario would be to
connect the Fault circuit to a warning light located in the control room. The
light can be set up to switch on when a fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for connecting to
an alarm system. The two wires attached to the Fault contacts form an open
circuit when (1) the Media Converter has lost power from one of the DC power
inputs, or (2) one of the ports for which the corresponding PORT ALARM Dip
Switch is set to ON is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
