DIN-Rail Mounting
The plastic DIN-rail attachment plate should already be fixed to the rear
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 DIN-rail kit is situated
towards the top, as shown in the figures below.
STEP 1:
Insert the top of the DIN r
ail
into the slot.
STEP 2:
The DIN
-rail attachment unit will
snap into place as shown below.
To remove Moxa EDS-205 from the
DIN r
ail, insert a flat-blade screw
dr
iver horizontally into the DIN-r
ail
kit under the EDS
-205, and then
pull it upwards
and release the EDS
to
wards you and away from the
DIN r
ail.
Or you may take the following steps to
remove the EDS-205 from the
DIN
rail.
Step 1:
P
ress the middle of the flat side
of the mounting kit as indicated
.
Pull the EDS-205 downwards.
Step 2:
Release it towards you and away
from the DIN rail.

Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord
before installing and/or
wiring your Moxa EtherDevice Switch.
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 points:
•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 that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding the Moxa EtherDevice Switch
Grounding and wire routing help limit the effects
of noise due to electromagnetic interference
(EMI). Run the ground connection from the right
most contact of the 3
-contact terminal block 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 Power Inputs
The two left-most contacts of the 3-contact terminal block connector on
the EDS’s top panel are used for the DC input. 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 the EDS’s top panel.
ATTENTION
•
Only connect to a class 2 power supply.
•
Only use 60/75°C copper (CU) wire, 28-12 AWG.
•Use a maximum torque of 4.5 in-lb.
Communication Connections
The EDS-205 has five10/100BaseT(X) Ethernet ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS switch’s front panel are
used to connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

LED Indicators
The front panel of the Moxa EtherDevice Switch contains several LED
indicators. The function of each LED is described in the table below.
LED

State
Description
P AMBER On
Power is being supplied to the power
input.
Off
Power is not being supplied to the
power input.
10M (TP) GREEN
On
The TP port’s 10 Mbps link is active.
Blinking
Data is being transmitted at 10 Mbps.
Off
The TP port’s 10 Mbps link is inactive
100M (TP) GREEN
On
The TP port’s 100 Mbps link is active.
Blinking
Data is being transmitted at 100 Mbps.
Off
The 100BaseTX port’s link is inactive.
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the switch’s
10/100BaseTX ports to any kind of Ethernet device, regardless of the type
of Ethernet cable being used for the connection. This means that you can
use either a straight-through or cross-over cable to connect the EDS to
your Ethernet devices.
Dual Speed Functionality and Switching
The switch’s 10/100 Mbps switched RJ45 port auto negotiates with the
connected device for the fastest data transmission rate supported by both
devices. All models of Moxa EtherDevice Switch are plug-and-play
devices; software configuration is not required at installation, or during
maintenance. The half/full duplex mode for the switched RJ45 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.

Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is
made to either filter or forward the packet. Packets with source and
destination addresses belonging to the same port segment will be filtered,
constraining those packets to one port, and relieving the rest of the
network from the need to process them. A packet with destination
address on another port segment will be forwarded to the appropriate
port, and will not be sent to the other ports where it is not needed.
Packets that are used to maintain the operation of the network (such as
the occasional multi-cast packet) are forwarded to all ports. The switch
operates in the store-and-forward switching mode, which eliminates bad
packets and enables peak performance to be achieved when there is
heavy traffic on the network.
Switching and Address Learning
The Moxa EtherDevice switch has an address table that can hold up to 1K
node addresses, making it suitable for use with large networks. The
address tables are self-learning, so that as nodes are added or removed,
or moved from one segment to another, the switch automatically adds
new node locations to the tables. An address-aging algorithm causes the
least-used addresses to be deleted in favor of newer, more frequently
used addresses. To reset the address buffer, power down the unit and
then power it back up.
Auto-Negotiation and Speed Sensing
All of the switch’s RJ45 Ethernet ports independently support
auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with
operation according to the IEEE 802.3u standard. This means that some
nodes could be operating at 10 Mbps, while at the same time, other nodes
are operating at 100 Mbps.
Auto-negotiation takes place when an RJ45 cable connection is made, and
then each time a LINK is enabled. The Moxa EtherDevice switch
advertises its capability for using either 10 Mbps or 100 Mbps
transmission speeds, with the device at the other end of the cable
expected to similarly advertise. The two devices will agree to operate at
either 10 Mbps or 100 Mbps.
If a Moxa EtherDevice switch’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 802.3u standard.
