DIN-Rail Mounting  
The plastic DIN-Rail attachment plate should already be fixed to the rear panel  
of EDS-208 when you take it out of the box. If you need to reattach the  
DIN-Rail attachment plate to EDS-208, 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 slot.  
The DIN-Rail attachment unit will  
snap into place as shown below.  
DIN-Rail  
DIN-Rail  
To remove Moxa EDS-208 from the  
DIN-Rail, insert a flat-blade screw driver  
horizontally into the DIN-Rail kit under  
the EDS-208, and then pull it upwards  
and release EDS-208 towards you away  
from the DIN-Rail.

Wiring Requirements  
ATTENTION  
Safety First!  
Be sure to disconnect the power cord before installing and/or  
wiring your EDS-208.  
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:  
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
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.  
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.  
y
y
It is strongly advised that you label wiring to all devices in the system when  
necessary.  
Grounding EDS-208  
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  
EDS-208’s top panel are used for both the DC and AC inputs of EDS-208. Top  
and front views of one of the terminal block connectors are shown here.  
STEP 1: Insert the negative/positive DC or AC  
wires into the V-/V+ terminals.  
STEP 2: To keep the DC or AC 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  
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-208 has 7 or 8 10/100BaseT(X) Ethernet ports, and 1 or 0 (zero)  
100BaseFX (SC/ST-type connector) multi-mode fiber ports.  
10/100BaseT(X) Ethernet Port Connection  
The 10/100BaseT(X) ports located on EDS-208’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.

RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring  
100BaseFX Ethernet Port Connection  
The concept behind the SC/ST port and cable is quite straightforward. Suppose  
you are connecting devices I and II. Contrary to electrical signals, optical  
signals do not require a circuit in order to transmit data. Consequently, one of  
the optical lines is used to transmit data from device I to device II, and the  
other optical line is used to transmit data from device II to device I, for  
full-duplex transmission.  
All you need to remember is to connect the Tx (transmit) port of device I to the  
Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx  
(transmit) port of device II. If you make your own cable, we suggest labeling  
the two sides of the same line with the same letter (A-to-A and B-to-B, as  
shown below, or A1-to-A2 and B1-to-B2).

Auto MDI/MDI-X Connection  
The Auto MDI/MDI-X function allows users to connect EDS-208’s  
10/100BaseTX ports to any kind of Ethernet device, regardless of how the  
Ethernet cable is wired. This means that you can use either a straight-through  
cable or cross-over cable to connect EDS-208 to Ethernet devices.  
Dual Speed Functionality and  
Switching  
EDS208’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 EDS-208 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  
either to filter or to 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.  
EDS-208 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  
EDS-208 has an address table that can hold up to 1,000 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, EDS-208 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 EDS-208’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 a “live” RJ45 cable is connected to the  
switch, and then each time a LINK is enabled. EDS-208 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 an EDS-208 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.
