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.

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:
yUse 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.
yNOTE: 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.
yYou 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.
yKeep input wiring and output wiring separated.
yIt 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.
yOnly connect to a class 2 power supply.
yUse 60/75°C copper (CU) wire 28-12 AWG only.
yUse a maximum torque of 4.5 in-lb.

Communication Connections
EDS-205 has five10/100BaseT(X) Ethernet ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on EDSS’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.

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

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 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 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.
