Overview
The EDS-205A/208A series of industrial Ethernet switches are entry-level
industrial 5 and 8-port Ethernet switches that support IEEE 802.3, IEEE 802.3u,
and IEEE 802.3x with 10/100M, full/half-duplex, and MDI/MDIX
auto-sensing.
The EDS-205A/208A series provides 12/24/48 VDC (9.6 to 60VDC)/18 to 30
VAC redundant power inputs that can be connected simultaneously to a live
AC/DC power source. The switches are available with a standard operating
temperature range from -10 to 60°C, or with a wide operating temperature
range from -40 to 75°C, and IP30 metal housing makes them rugged enough
for any harsh industrial environment.
To provide greater versatility for use with applications from different industries,
the EDS-205A/208A also allow users to enable or disable broadcast storm
protection with DIP switches on the outer panel.
The EDS-205A/208A switches can be easily installed with DIN-Rail mounting
as well as distribution boxes. The DIN-rail mounting capability and IP30 metal
housing with LED indicators make the plug-and-play EDS-205A/208A
switches reliable and easy to use.
NOTE Throughout this Hardware Installation Guide, we use EDS as an
abbreviation for Moxa EtherDevice Switch:
EDS = Moxa EtherDevice Switch

Mounting Dimensions (unit = mm)

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 EDS from the DIN-Rail, simply reverse Steps 1 and 2 above.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the
EDS-205A/208A on the wall, as shown in the following figures.
STEP 1: Remove the
aluminum DIN-Rail
attachment plate from the
EDS-205A/208A’s rear
panel, and then attach the
wall mount plates as shown
in the diagram at the right.

STEP 2:
Mounting the EDS-205A/208A on the wall requires 4
screws. Use the switch, 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 completely—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 on the wall, insert the four screw heads through the
large parts of the keyhole-shaped apertures, and then slide the
EDS-205A/208A 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
correct power supply voltage is listed on the product label. Check
the voltage of your power source to make sure that 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 SELV 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 points:
yUse 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.
yYou 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.
yKeep input wiring and output wiring separated.
yIt is strongly advised that you label wiring to all devices in the system when
necessary.

Grounding the 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 Redundant Power Inputs
The top two contacts and the bottom two contacts of the 4-contact terminal
block connector on the EDS’s top panel are used for the EDS’s two AC/DC
inputs. Top and front views of one of the terminal block connectors are shown
here.
Top View
Front View
STEP 1: Insert the negative/positive AC/DC
wires into the V-/V+ terminals.
STEP 2: To keep the AC/DC wires from pulling
loose, use a small flat-
b
lade 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 EtherDevice Switch to the AC/DC power
inputs, make sure the AC/DC power source voltage is stable.
Communication Connections
The EDS-205A models have 4 or 5 10/100BaseT(X) Ethernet ports, and 1 or 0
(zero) 100 BaseFX multi/single-mode (SC/ST-type connector) fiber ports. The
EDS-208A models have 6, 7 or 8 10/100BaseT(X) Ethernet ports, and 2, 1 or 0
(zero) 100 BaseFX multi/single-mode (SC/ST-type connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS’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.
