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:  
STEP 2:  
Insert the top of the DIN-Rail into  
The DIN-Rail attachment unit will  
the slot.  
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.

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 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.  
y Only connect to a class 2 power supply.  
y Use 60/75°C copper (CU) wire 28-12 AWG only.  
y Use 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.

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.
