Overview
The EDS-G205 series is equipped with 5 Gigabit Ethernet ports, making it
an ideal and economical solution for demanding, high bandwidth Gigabit
Ethernet applications. In addition, the built-in relay warning function
alerts system administrators when power failures or port breaks occur.
The EDS-G205 series includes 2 models: one with an operating
temperature range of 0 to 60°C, and the other one with extended
operating temperature range of -40 to 75°C. These 2 models have passed
a 100% burn-in test to ensure that they fulfill the special needs of
industrial automation control. The EDS-G205 series can be easily
installed with DIN-Rail mounting as well as distribution boxes.
NOTE
Throughout this Hardware Installation Guide, we use EDS as an
abbreviation for Moxa EtherDevice Switch:
EDS = Moxa EtherDevice Switch

DIN-Rail Mounting
The aluminum DIN-rail attachment plate should already be fixed to the
back panel of the EDS when you take it out of the box. If you need to
reattach the DIN-rail attachment plate, 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.
To remove the DIN-rail from the EDS, simply reverse Steps 1 and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the EDS on the
wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-rail attachment plate
from the EDS’s rear panel,
and then attach the wall
mount plates, as shown in
the
figure.
STEP 2:
Mounting
the EDS on the wall requires 4 screws. Use
the
s
witch, with wall mount plates attached, as a guide
t
o 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.
NOTE
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.
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.

- 6 -
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 the
EDS downwards, as indicated.
Tighten the four screws for
added
stability.

Wiring Requirements
WARNING
Safety First!
Turn
the power off before disconnecting modules or wires. The
proper
power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT use a voltage greater than
what is
specified on the product label.
These devices must be supplied by a
n
AELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.

WARNING
Safety First!
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:
•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 with similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring for 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
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 Alarm Contact
The Alarm Contact consists of the two middle contacts of the terminal
block on the EDS’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 explain the meaning of the two contacts used to
connect the Alarm Contact.

- 8 -
FAULT: The two middle contacts of the
6
-contact terminal block connector
are used to
detect both power faults and port faults. The
two wires attached to the Fault contacts form
a
n open circuit when:
1. EDS has lost power from one of the DC
power inputs.
OR
2. The PORT ALARM DIP switch for one of
the ports is set to ON, but the port is not
connected properly.
If
neither of these two conditions is satisfied,
the Fault circuit will
be closed.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the EDS’s top panel are used for the EDS’s DC
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.
ATTENTION
Before connecting
the
EDS to the DC power inputs, make sure the
DC power source voltage is stable.
Communication Connections
EDS-G205 Models have 5 10/100/1000BaseT(X) Ethernet ports.
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) 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.

- 9 -
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.

Redundant Power Inputs
Both power 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 the EDS’s power needs.

Alarm Contact
The Moxa EtherDevice Switch has one Alarm Contact located on the top
panel. For detailed instructions on how to connect the Alarm Contact
power wires to the two middle contacts of the 6-contact terminal block
connector, see the Wiring the Alarm Contact section on page 6. 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.
The Alarm Contact has two terminals that form a Fault circuit for
connecting to an alarm system. The two wires attached to the Fault
contacts form an open circuit when (1) EDS has lost power from one of
the DC power inputs, or (2) one of the ports, for which the corresponding
PORT ALARM DIP switch is set to ON, is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
DIP Switch Settings
The default setting for each DIP switch is OFF.
The following table explains the effect of setting
the DIP switches to the ON positions.
DIP Switch
Setting
Description
BSP
ON
Enables broadcast storm protection
OFF
Disables broadcast storm protection
----
refers to Jumbo
Frame
ON
Enables jumbo frame function
OFF Disables jumbo frame function
PORT Alarm
ON
Enables the corresponding PORT Alarm. If
the port’s link fails, the relay will form an
open circuit and the fault LED will light up.
OFF
Disables the corresponding PORT Alarm.
The relay will form a closed circuit and the
Fault LED will never light up.
ATTENTION
To actively update DIP switch settings, power off and then power
on the EDS.
