Mounting Dimensions
DIN-Rail Mounting
The plastic DIN-Rail attachment plate should already be fixed to the
rear panel of EDS when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to EDS, 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-Rail 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-Rail, insert a flat-blade
screw driver horizontally into the
DIN-Rail kit under the EDS-205,
and then pull it upwards and
release EDS towards you away
from the DIN-Rail.

Wiring Requirements
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:
y 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.
y 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.
y 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.
y Keep input wiring and output wiring separated.
y It is strongly advised that you label wiring to 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 right
most of 3-contact terminal block to the
grounding surface prior to connecting devices.
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
EDS’s top panel are used for EDS’s DC or AC 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.
Communication Connections
EDS-205 has five 10/100BaseT(X) Ethernet ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on EDS’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.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect MOXA
EtherDevice Switch’s 10/100BaseTX 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 EDS to Ethernet devices.
Dual Speed Functionality and
Switching
MOXA EtherDevice 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, so that 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 in maintaining the operation of the network (such
as the occasional multi-cast packet) are forwarded to all ports.
MOXA EtherDevice 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
MOXA EtherDevice Switch has an address table that can hold up to 1K
node addresses, which makes 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, MOXA EtherDevice
Switch automatically keeps up with new node locations. An addressaging 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 MOXA EtherDevice 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. 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. Depending on what type of device is
connected, this will result in agreement to operate at a speed of either
10 Mbps or 100 Mbps.
If a MOXA EtherDevice Switch 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.
