The concept behind the LC port and cable is quite straightforward.

Suppose you are connecting devices I and II. Unlike electrical signals,

optical signals do not require a circuit in order to transmit data.

Consequently, one of the optical lines is used to transmit data from device

I to device II, and the other optical line is used to transmit data from

device II to device I, for full-duplex transmission.

Remember 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. If you make your own cable, we suggest labeling the two

sides of the same line with the same letter (A-to-A and B-to-B, as shown

below, or A1-to-A2 and B1-to-B2).

ATTENTION

This is a Class 1 Laser/LED product. To avoid causing serious

damage to your eyes, do not stare directly into the Laser Beam.

Redundant Power Inputs

Both power inputs can be connected simultaneously to live AC/DC power

sources. If one power source fails, the other live source acts as a backup,

and automatically supplies all of the EDS’s power needs.

Alarm Contact

The Moxa EtherDevice Switch 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 on page 6. 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) EDS has lost power from one of

the AC/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.
