STEP 1: Insert the

negative/positive DC wires into

the V-/V+ terminals, respectively.

STEP 2: To keep the DC wires

from pulling loose, use a small

flat-blade screwdriver to tighten

the wire-clamp screws on the front

of the terminal block connector.

STEP 3: Insert the plastic terminal

block connector prongs into the

terminal block receptor, which is

located on the EDS-518A’s top

panel.

Wiring the Digital Inputs

EDS-518A has two sets of digital inputs, DI 1 and DI 2. Each DI consists of

two contacts of the 6-pin terminal block connector on EDS’s top panel, which

are used for EDS’s two DC inputs. The top and front views of one of the

terminal block connectors are shown here.

STEP 1: Insert the negative

(ground)/positive DI wires into the ┴

/I1 terminals, respectively.

STEP 2: To keep the DI wires from

pulling loose, use a small flat-blade

screwdriver to tighten the wire-clamp

screws on the front of the terminal

block connector.

STEP 3: Insert the plastic terminal

block connector prongs into the

terminal block receptor, which is

located on the EDS-518A’s top panel.

Communication Connections

All models of EDS-518A have one RJ45 console port (RS-232 interface),

between 14 and 16 10/100BaseTX Ethernet ports. Some models also have 2

100BaseFX (SC/ST-type connector) fiber ports.

In this section, we present two types of diagrams—Pinout Diagrams and

Cable Wiring Diagrams—to convey information about the ports and the

cables used to connect Moxa EDS-518A to other devices:

Pinouts—The meaning of the “Pinouts” diagrams is straightforward. The

diagrams simply display the type of signal passing through each of the port’s

pins.

Cable Wiring—Diagrams labeled “Cable Wiring” present standard cable

wiring schemes for cables used to connect Moxa EtherDevice Switch’s ports

to other devices. These diagrams display three pieces of information:

1. When building your own cable, refer to the “pin-to-pin” Cable Wiring

information displayed between the two vertical dashed lines to see

which pin of the connector on the left should be connected to which pin

of the connector on the right.
