Overview

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

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

Ethernet connection.

For EDS-205, you could choose either DC power input from 12 to 48 V or AC

power input from 18 to 30V. These products can operation from –10 to 60oC,

and the rugged hardware design makes EDS-205 perfect for ensuring that your

Ethernet equipment can meet demanding industrial applications.

NOTE Throughout this Hardware Installation Guide, we use EDS as an

abbreviation for Moxa EtherDevice Switch:

EDS = Moxa EtherDevice Switch

Mounting Dimensions

DIN-Rail Mounting

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

of EDS when you take it out of the box. If you need to reattach the DIN-Rail

attachment plate to EDS, 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-Rail 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-Rail, insert a flat-blade screw

driver horizontally into the DIN-Rail

kit under the EDS-205, and then pull

it upwards and release EDS towards

you away from the DIN-Rail.

Wiring Requirements

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.

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.

yNOTE: 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 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 of 3-contact terminal block 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 Power Inputs

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

top panel are used for EDS’s DC or AC 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.

yOnly connect to a class 2 power supply.

yUse 60/75°C copper (CU) wire 28-12 AWG only.

yUse a maximum torque of 4.5 in-lb.

Communication Connections

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

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on EDSS’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.

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect Moxa EtherDevice

Switch’s 10/100BaseTX ports to any kind of Ethernet device, without paying

attention to the type of Ethernet cable being used for the connection. This

means that you can use either a straight-through cable or cross-over cable to

connect EDS to Ethernet devices.

Dual Speed Functionality and

Switching

Moxa EtherDevice 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, 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 EtherDevice 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

Moxa EtherDevice Switch has an address table that can hold up to 1K 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 EtherDevice Switch 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 EtherDevice 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. 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. 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 EtherDevice Switch 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.
