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.
Before tightening 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.
NOTE
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

Wiring Requirements
Warning
Do not disconnect modules or wires unless power has been switched
off or the area is known to be nonhazardous.
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 the Low Voltage Directive 73/23/EEC
and 93/68/EEC".
This unit is a building-in type. During installation into certain end
equipment, it should comply with the fire enclosure requirements
of IEC 60950/EN60950 or similar.
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.

Installing MOXA EtherDevice Switch
You should also pay attention to the following items :
??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 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.
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.
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.

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 two 100BaseFX (SC-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 Server’ 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 learn which pin of the left connector should
be connected to which pin of the right
connector.
2. The information to the left of the left vertical
dashed lines gives the pinouts of the relevant
MOXA EtherDevice Server 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.
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 EtherDeviceTM 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 automatically adjusted 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 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

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
the 6-pin terminal block connector, see the Wiring the Relay Contact
section from Chapter 3.
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.
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.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect MOXA
EDS-508’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 in use. 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 in 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 in use. The first type is a
straight-through cable, and the second type is a cross-over cable. The
general connection rules are:
?? A straight-through cable is used to connect dislike ports:
MDI ? MDI-X.

MDI ? MDI or MDI-X ? 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 EDS-508’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
connector. Consequently, you should use fiber cables that have SC
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 2 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.
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.

Hardware Overview
Switching and Address Learning
MOXA EDS-508 has an address table that can hold up to 2K 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 EDS-508’s 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 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.
