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.

ATTENTION
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.
This is a Class 1 Laser/LED product. Do not stare into
the Laser Beam.
