DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the back
panel of EDS-508 when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to EDS-508, make sure the stiff metal spring is
situated towards the top, as shown in the figures below.
STEP 1—Insert the top of the
DIN-Rail into the slot just below
the stiff metal spring.
STEP 2—The DIN-Rail attachment
unit will snap into place as shown
below.

STEP 2—Mounting MOXA EDS-508 on the wall requires 4
screws. Use the EDS-508, with wall mount plates attached, as a
guide to mark the correct locations of the 4 screws. The heads of
the screws should be less than 6.0 mm in diameter, and the shafts
should be less than 3.5 mm in diameter, as shown in the figure at
the right.
6.0 mm
3.5 mm
NOTE
Before tightening the screws into the wall, make sure the screw
head and shank size are suitable by inserting the screw into one
of the keyhole-shaped apertures of the Wall Mounting Plates.
Do not screw the screws in all the
way—leave about 2 mm to allow
room for sliding the wall mount panel
between the wall and the screws.
STEP 3—Once the screws are fixed
in the wall, insert the four screw
heads through the large parts of the
keyhole-shaped apertures, and then
slide EDS-508 downwards, as
indicated below. Tighten the four
screws for more stability.

Wiring Requirements
WARNING
Do not disconnect modules or wires unless power has been switched
off or the area is known to be non-hazardous. The devices may only be
connected to the supply voltage shown on the type plate. The devices
are designed for operation with a Safety Extra-Low Voltage. Thus,
they may only be connected to the supply voltage connections and to
the signal contact with the Safety Extra-Low Voltages (SELV) in
compliance with IEC950/ EN60950/ VDE0805.
WARNING
Substitution of components may impair suitability for Class I,
Division 2 and Zone 2. These devices must be supplied by a SELV
source as defined in Low Voltage Directive 73/23/EEC and
93/68/EEC.
WARNING
This equipment has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0324537U. Each module is
marked
II 3G and is suitable for use in Zone 2 Explosive
Atmospheres. The device must be installed in a minimum IP 54
enclosure as defined in IEC 60529 and EN 60529.
Wiring MOXA EtherDevice™ Switch
3-3
ATTENTION
This unit is a built-in type. When the unit is installed in another piece
of equipment, the equipment enclosing the unit must comply with fire
enclosure regulation IEC 60950/EN60950 (or similar regulation).
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:
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.
EDS-508 Hardware Installation Guide

Grounding MOXA EDS-508
Grounding and wire routing help limit the effects of noise due to electromagnetic
interference (EMI). Run the ground connection from the ground screw 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 Relay Contact
EDS-508 has two sets of relay output—relay 1 and relay 2. Each Relay Contact
consists of the two contacts of the terminal block on EDS-508’s top panel. You
may refer to the next section for detailed instructions on how to connect the
wires to the terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.
In this section, we will explain the meaning of the two contacts used to connect
the Relay Contact.
Relay1 Relay2
Relay1 Relay2
FAULT:
The two sets of relay contacts of the 6-pin
terminal block connector are used to detect
user-configured events. The two wires
attached to the Fault contacts form an open
circuit when a user-configured event is
triggered. If a user-configured event does
not occur, the Fault circuit will be closed.
Wiring MOXA EtherDevice™ Switch

Wiring the Redundant Power Inputs
EDS-508 has two sets of power input—power input 1 and power input 2.The top
two contacts and the bottom two contacts of the 6-pin terminal block connector
on EDS’s top panel are used for EDS’s two digital inputs. Top and front views of
one of the terminal block connectors are shown here.

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-508’s
top panel.
Wiring the Digital Inputs
EDS-508 has two sets of digital input, DI 1 and DI 2. Each DI consists of two
contacts of the 6-pin terminal block connector on EDS’s top panel, which are
used for EDS’s two DC inputs. Top and front views of one of the terminal block
connectors are shown here.

Communication Connections
All models of EDS-508 have one RJ45 console port (RS-232 interface), and
between six and eight 10/100BaseTX Ethernet ports. Some models also have one
or two 100BaseFX (SC/ST-type connector) fiber ports.
In this section, we present two types of diagrams—Pinout Diagrams and Cable
Wiring Diagrams—to convey information about the ports and the cables used to
connect MOXA EDS-508 to other devices:
Pinouts—The meaning of the “Pinouts” diagrams is straightforward. The
diagrams simply display the type of signal passing through each of the port’s
pins.
Cable Wiring—Diagrams labeled “Cable Wiring” present standard cable wiring
schemes for cables used to connect MOXA EtherDevice Switch’s ports to other
devices. These diagrams display three pieces of information:
1. When building your own cable, refer to the “pin-to-pin” Cable Wiring
information displayed between the two vertical dashed lines to see which pin
of the connector on the left should be connected to which pin of the
connector on the right.
2. The information to the left of the left vertical dashed lines gives the pinouts
of the relevant MOXA EtherDevice Switch port.
3. The information to the right of the right vertical dashed line gives the
pinouts of the opposing device’s port.
NOTE
1. The pin numbers for male DB9 and DB25 connectors, and
hole numbers for female DB9 and DB25 connectors are
labeled on the connector. However, the numbers are typically
quite small, so you may need to use a magnifying glass to see
the numbers clearly.
2. The pin numbers for both 8-pin and 10-pin RJ45 connectors
(and ports) are typically not labeled on the connector (or port).
Refer to the Pinout and Cable Wiring diagrams below to see
how RJ45 pins are numbered
Wiring MOXA EtherDevice™ Switch

RS-232 Connection
MOXA EDS-508 has one RS-232 (10-pin RJ45) console port, located on the top
panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable (see the cable wiring
diagrams below) to connect MOXA EDS-508’s console port to your PC’s COM
port. You may then use a console terminal program, such as MOXA PComm
Terminal Emulator, to access MOXA EDS-508’s console configuration utility.

10/100BaseTx Ethernet Port Connection
The 10/100BaseTX ports located on MOXA EtherDevice Switch’s front panel
are used to connect to Ethernet-enabled devices. Most users will choose to
configure these ports for Auto MDI/MDI-X mode, in which case the port’s
pinouts are adjusted automatically depending on the type of Ethernet cable used
(straight-through or cross-over), and the type of device (NIC-type or
HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.

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 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 are making 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).

Redundant Power Inputs
MOXA EDS-508 has two DC power inputs located on its top panel. For detailed
instructions on how to connect the power wires to the terminal block connector,
see the Wiring the Redundant Power Inputs section from Chapter 3.
From the user’s point of view, the function of the redundant power inputs is quite
straightforward. Both inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup, and
automatically supplies all of MOXA EDS-508’s power needs.
Relay Contacts
MOXA EDS-508 has two Relay Contacts located on the top panel. For detailed
instructions on how to connect the Relay Contact power wires to th
e 6-pin
terminal block connector, see the Wiring the Relay Contact section from
Chapter 3.
The Alarm Contact has two terminals that form a Fault circuit for connecting to
an alarm system. These two contacts form a closed circuit when MOXA
EDS-508 is receiving power from both DC power inputs. The circuit opens if
power to one of the power inputs is cut off, or if the MOXA EDS-508 self-test
fails, alerting the user to check either the power supply or function of the Server.
The Alarm Contact has two terminals that form a Fault circuit for connecting to
an alarm system. Two wires attached to the Fault contacts form an open circuit
when a user-configured event is triggered. If a user-configured event does not
occur, the Fault circuit will be closed.
A typical scenario would be to connect the Fault circuit to a warning light
located in the control room. The light can be set up to switch on when a fault is
detected.
LED Indicators
The front panel of MOXA EDS-508 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. To
understand the meaning of this statement, you simply need to remember that
there are two types of Ethernet ports, and two types of Ethernet cables. See the
10/100BaseTX Ethernet Port Connection section from Chapter 3 for detailed
Pinout and Cable Wiring diagrams. In this section, we give a short primer of the
terminology, and indicate which cable should be used to connect which types of
ports.
There are two types of Ethernet port. The first type is called an MDI (Medium
Dependant Interface) port, and is what you find on your PC’s NIC (Network
Interface Card). The second type is called an MDI-X (Medium Dependant
Interface, Crossover) port, and is the type of port found on a standard HUB or
switch. For this reason, we often refer to an MDI port as being NIC-type, and an
MDI-X port as being HUB/Switch-type.
There are also two types of Ethernet cable. The first type is a straight-through
cable, and the second type is a cross-over cable. The general connection rules
are:
y A straight-through cable is used to connect unlike ports:
MDI Q MDI-X.
y A cross-over cable is used to connect like ports:
MDI Q MDI or MDI-X Q MDI-X.
For example, you should use a straight-through cable to connect your computer’s
Ethernet NIC to a HUB or switch, but use a cross-over cable to connect your
computer’s Ethernet NIC to another computer’s Ethernet NIC.
Fiber Ports
MOXA EtherDevice Switch’s fiber switched ports operate at a fixed 100 Mbps
speed and full-duplex mode to provide the best performance. The fiber ports are
factory-built as either a multi-mode or single-mode SC/ST connector.
Consequently, you should use fiber cables that have SC/ST connectors at both
ends. When plugging the connector into the port, make sure the slider guide is
positioned to the right side so that it fits snuggly into the port.

The 100 Mbps fiber ports are switched ports, and perform as a domain, providing
a high bandwidth backbone connection that supports long fiber cable distances
(up to 5 km for multi-mode, and 15, 40, or 80 km for single-mode) for
installation versatility.
Dual Speed Functionality and Switching
MOXA EDS-508’s 10/100 Mbps RJ45 switched ports can be configured for 10
Mbps operation, 100 Mbps operation, or to auto-negotiate with the connected
device for the fastest data transmission rate supported by both devices.
All models of MOXA EDS-508 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.
EDS-508 Hardware Installation Guide
4-6
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 EDS-508 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 EDS-508 has an address table that can hold up to 2000 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 EDS-508 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 EDS-508’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.
Hardware Overview
4-7
If a MOXA EDS-508 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.
