Overview

The Moxa, EDS-205 series EtherDevice™ switches are entry-level 5- port

Ethernet switches that provide a cost-effective solution for your industrial

Ethernet connection.

The EDS-205 Series supports DC power input from 12 to 48 V. These

switches can operate from -10 to 60oC, and the rugged hardware design

makes the EDS-205 switches perfect for ensuring that your Ethernet

equipment can be used for demanding industrial applications.

NOTE

Throughout this Hardware Installation Guide, we use EDS as an

abbreviation for Moxa EtherDevice Switch:

EDS = Moxa EtherDevice Switch

DIN-Rail Mounting

The plastic DIN-rail attachment plate should already be fixed to the rear

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 DIN-rail kit is situated

towards the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN r

ail

into the slot.

STEP 2:

The DIN

-rail attachment unit will

snap into place as shown below.

To remove Moxa EDS-205 from the

DIN r

ail, insert a flat-blade screw

iver horizontally into the DIN-r

ail

kit under the EDS

-205, and then

pull it upwards

and release the EDS

wards you and away from the

DIN r

ail.

Or you may take the following steps to

remove the EDS-205 from the

DIN

rail.

Step 1:

ress the middle of the flat side

of the mounting kit as indicated

Pull the EDS-205 downwards.

Step 2:

Release it towards you and away

from the DIN rail.

Wiring Requirements

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:

•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 the Moxa EtherDevice Switch

Grounding and wire routing help limit the effects

of noise due to electromagnetic interference

(EMI). Run the ground connection from the right

most contact of the 3

-contact terminal block 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.

- 7 -

Wiring the Power Inputs

The two left-most contacts of the 3-contact terminal block connector on

the EDS’s top panel are used for the DC input. 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+ 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 the EDS’s top panel.

ATTENTION

•

Only connect to a class 2 power supply.

•

Only use 60/75°C copper (CU) wire, 28-12 AWG.

•Use a maximum torque of 4.5 in-lb.

Communication Connections

The EDS-205 has five10/100BaseT(X) Ethernet ports.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on the EDS switch’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.

LED Indicators

The front panel of the Moxa EtherDevice Switch contains several LED

indicators. The function of each LED is described in the table below.

LED

Description

P AMBER On

Power is being supplied to the power

input.

Off

Power is not being supplied to the

power input.

10M (TP) GREEN

The TP port’s 10 Mbps link is active.

Blinking

Data is being transmitted at 10 Mbps.

Off

The TP port’s 10 Mbps link is inactive

100M (TP) GREEN

The TP port’s 100 Mbps link is active.

Blinking

Data is being transmitted at 100 Mbps.

Off

The 100BaseTX port’s link is inactive.

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect the switch’s

10/100BaseTX ports to any kind of Ethernet device, regardless of the type

of Ethernet cable being used for the connection. This means that you can

use either a straight-through or cross-over cable to connect the EDS to

your Ethernet devices.

Dual Speed Functionality and Switching

The switch’s 10/100 Mbps switched RJ45 port auto negotiates with the

connected device for the fastest data transmission rate supported by both

devices. All models of Moxa EtherDevice Switch are plug-and-play

devices; 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 to maintain the operation of the network (such as

the occasional multi-cast packet) are forwarded to all ports. The switch

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

The Moxa EtherDevice switch has an address table that can hold up to 1K

node addresses, making 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, the switch automatically adds

new node locations to the tables. 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 the switch’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. The 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. The two devices will agree to operate at

either 10 Mbps or 100 Mbps.

If a Moxa EtherDevice switch’s 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.
