ports (4 10/100/1000BaseT(X) ports and 1 combo 10/100/1000BaseT(X)
or 100/1000BaseSFP port), making them ideal, economical solutions 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, and the add-on 4-pin DIP switches
can be used to configure broadcast storm protection, jumbo frame rate,
IEEE 802.3az energy saving, and 100/1000 SFP speed switching. The
EDS-G205-1GTXSFP series includes 2 models: one with an operating
temperature range of -10 to 60°C, and the other with an 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-G205-1GTXSFP series can be
easily installed on a DIN rail or in distribution boxes.

DIN Rail Mounting
The aluminum DIN rail attachment plate should already be fixed to the
back panel of the switch 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 switch, simply reverse Steps 1 and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the switch on
the wall, as illustrated below.
STEP 1:
Remove the aluminum DIN
rail attachment plate from
the
switch’s
rear panel, and
then attach the wall mount
plates, as shown in the
f
igure.
STEP 2:
Mounting
the switch
on the wall requires 4 screws. Use
the
s
witch, with wall mount plates attached, as a guide
to mark the correct locations of the 4 s
crews. 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 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 the
switch
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.

- 7 -
•We strongly advise labeling the wiring for all devices in the system.
Grounding Your Moxa 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 produ
ct 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 switch’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.
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. The switch 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 switch’s top panel are used for DC inputs.
Top and front views of one of the terminal block connectors are shown
here.

- 8 -
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 switch’s top
panel.
ATTENTION
Before connecting
the switch
to the DC power inputs, make sure
the DC power source voltage is stable.
Communication Connections
EDS-G205-1GTXSFP switches have 2 types of communication port:
•4 10/100/1000BaseT(X) Ethernet ports
•1 combination 10/100/1000T(X) or 100/1000BaseSFP port
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) ports located on 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.

100/1000BaseSFP (mini-GBIC) Fiber Port
One of the Gigabit Ethernet ports on the EDS-G205-1GTXSFP is an SFP
slot, which requires 100M or 1G mini-GBIC fiber transceivers to work
properly. Moxa provides complete transceiver models for various distance
requirements.
The concept behind the LC port and cable is straightforward. Suppose you
are connecting devices I and II. Unlike 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.
Remember 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

- 10 -
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).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the laser beam.
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 switch’s power needs.
Alarm Contact
The EDS-G205-1GTXSFP 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 7. 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) the switch 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.
