DIN-Rail Mounting

The aluminum DIN-rail attachment plate should already be fixed to the
back panel of the EDS when you take it out of the box. If you need to
reattach the DIN-rail attachment plate, make sure the stiff metal spring is
situated towards the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN

-rail into

the slot just

below the stiff metal

spring.

STEP 2:

The DIN

-rail attachment unit will

snap into place as shown below.

To remove the DIN-rail from the EDS, simply reverse Steps 1 and 2.

Wall Mounting (optional)

For some applications, you will find it convenient to mount the EDS on the
wall, as illustrated below.

STEP 1:
Remove the aluminum
DIN

-rail attachment plate

from the EDS’s rear panel,
and then attach the wall
mount plates, as shown in
the

figure.

STEP 2:

Mounting

the EDS on the wall requires 4 screws. Use

the switch, with wall mount plates attached, as a guide
t

o mark the correct locations of the 4 screws. The

heads of the screws should be less than 6.0 mm in
diameter, and the shafts should be less than 3.5 mm in
diameter, as shown in the figure at the right.

NOTE

Before tightening screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.

Do not screw the screws in all the way—leave about 2 mm to allow room
for sliding the wall mount panel between the wall and the screws.

- 6 -

STEP 3:

Once the screws are fixed in
the wall, insert the four screw
heads through the large parts
of the keyhole

-shaped

apertures, and then slide the
EDS downwards, as indicated.
Tighten the four screws for
added

stability.

Wiring Requirements

WARNING

Safety First!

Turn

the power off before disconnecting modules or wires. The

proper power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT use a voltage greater than

what is

specified on the product label.

These devices must be supplied by an AELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.

- 7 -

WARNING

Safety First!

Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.

You should also pay attention to the following items:

• Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring
in the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.

• You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of thumb is
that wiring with similar electrical characteristics can be bundled
together.

• Keep input wiring and output wiring separated.

• It is strongly advised that you label wiring for all devices in the system

when necessary.

Grounding Moxa EtherDevice Switch

Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well

-grounded

mounting surface, such as a metal panel.

Wiring the Alarm Contact

The Alarm Contact consists of the two middle contacts of the terminal
block on the EDS’s top panel. You may refer to the next section for
detailed instructions on how to connect the wires to the terminal block
connector, and how to attach the terminal block connector to the terminal
block receptor.

In this section, we explain the meaning of the two contacts used to
connect the Alarm Contact.

- 8 -

FAULT: The two middle contacts of the

6

-contact terminal block connector

are used to
detect both power faults and port faults. The
two wires attached to the Fault contacts form
a

n open circuit when:

1. EDS has lost power from one of the DC
power inputs.

OR

2. The PORT ALARM DIP switch for one of

the ports is set to ON, but the port is not

connected properly.

If

neither of these two conditions is satisfied,

the Fault circuit will

be closed.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the EDS’s top panel are used for the EDS’s DC
inputs. Top and front views of one of the terminal block connectors are
shown here.

STEP 1:

Insert the negative/positive DC

wires into the

V-/V+ terminals.

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 EDS’s top

panel.

ATTENTION

Before connecting

the

EDS to the DC power inputs, make sure the

DC power source voltage is stable.

Communication Connections

EDS-G205 Models have 5 10/100/1000BaseT(X) Ethernet ports.

10/100/1000BaseT(X) Ethernet Port Connection

The 10/100/1000BaseT(X) ports located on Moxa EtherDevice Switch’s
front panel are used to connect to Ethernet-enabled devices. Most users
will choose to configure these ports for Auto MDI/MDI-X mode, in which
case the port’s pinouts are adjusted automatically depending on the type
of Ethernet cable used (straight-through or cross-over), and the type of
device (NIC-type or HUB/Switch-type) connected to the port.

- 9 -

In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.

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 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 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 Settings

The default setting for each DIP switch is OFF.
The following table explains the effect of setting
the DIP switches to the ON positions.

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect the EDS’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, without
paying attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or cross-over cable to connect the EDS to Ethernet devices.

Triple Speed Functionality and Switching

The EDS’s 10/100/1000 Mbps RJ45 switched port auto negotiates with
the connected device for the fastest data transmission rate supported by
both devices. The EDS is a plug-and-play device, so software
configuration is not required at installation or during maintenance.

The half/full duplex mode for the RJ45 switched ports is user dependent
and changes (by auto-negotiation) to full or half duplex, depending on
which transmission speed is supported by the attached device.

- 12 -

Auto-Negotiation and Speed Sensing

The EDS’s RJ45 Ethernet ports independently support auto-negotiation
for transmission speeds of 10 Mbps, 100 Mbps, and 1000 Mbps, with
operation according to the IEEE 802.3 standard.

This means that some nodes could be operating at 10 Mbps, while at the
same time, other nodes are operating at 100 Mbps or 1000Mbps.

Auto-negotiation takes place when an RJ45 cable connection is made, and
then each time a LINK is enabled. The EDS advertises its capability for
using 10 Mbps, 100 Mbps, or 1000 Mbps transmission speeds, with the
device at the other end of the cable expected to advertise similarly.
Depending on what type of device is connected, this will result in
agreement to operate at a speed of 10 Mbps, 100 Mbps, or 1000 Mbps.

If an EDS’s RJ45 Ethernet port is connected to a non-negotiating device,
it will default to 10 Mbps speed and half-duplex mode, as required by the
IEEE 802.3 standard.
