100/1000Base-X Fiber Port
The Fiber ports on the EDS-2010/2018-ML Series are SFP type slots,
which support both 100Base-FX and 1000Base-X speeds. Moxa
provides complete transceiver models for various distance
requirements.
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).

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

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 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 10. 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 DC power inputs, or (2) one of the ports for which the
corresponding PORT ALARM DIP Switch is set to ON is not properly
