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.
2.
The information to the left of the left vertical dashed lines gives the
pinouts of the relevant Moxa EtherDevice Switch port.
3.
The information to the right of the right vertical dashed line gives the
pinouts of the opposing device’s port.
NOTE
1.
The pin numbers for male DB9 and DB25 connectors, and
hole numbers for female DB9 and DB25 connectors are
labeled on the connector. However, the numbers are
typically quite small, so you may need to use a magnifying
glass to see the numbers clearly.
2.
The pin numbers for both 8-pin and 10-pin RJ45 connectors
(and ports) are typically not labeled on the connector (or
port). Refer to the following Pinout and Cable Wiring
diagrams to see how RJ45 pins are numbered.
