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 Moxa Industrial Media Converter’s power needs.
Alarm Contact
Moxa Industrial 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) IMC 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.
Dip Switch Setting
IMC-101 series DIP switch
123
ON DIP
Dip Switch 1 (Default: Off )
ON: Enables the PORT Alarm. If the port’s link fails, the
relay will form an open circuit and the fault LED will
light up.
Off: Disables the corresponding PORT Alarm. The relay
will form a closed circuit and the Fault LED will
never light up.
Dip Switch 2 (Default: ON )
ON: Enables full duplex for 100BaseFX
Off: Disables full duplex for 100BaseFX
Dip Switch 3
Reserved for future use
To activate the updated DIP switch setting, power off and then power on the
IMC.
