Chapter One INTRODUCTION
The D2 W MDME 2400 Industrial Wi-Fi Wireless Ethernet module provides wireless connections
between Ethernet devices or Ethernet wired networks (LANs). It complies with the IEEE 802.11b
standard. The D2 W MDME 2400 has an internal 2.4 GHz direct sequence spread spectrum (DSSS)
wireless transceiver, which can be used without a radio license in most countries. Users can select
one of 11 x 5 MHz wide channels, with the first channel centered at 2.412 GHz.
Note that regulations in North America and part of Europe permit all 11 channels to be
used in these countries. Please check with your Cooper Crouse-Hinds representative for
the permitted channel usage in your country.
The D2 W MDME 2400 unit also provides two serial connections as well as the Ethernet
connections. It is possible to use all three data connections concurrently, allowing the D2 W MDME
2400 to act as a Device Server. Wireless connections can be made between serial devices and
Ethernet devices; however, appropriate driver applications are required in the host devices to handle
the different data format. The D2 W MDME 2400 does provide connection functionality between
serial “Modbus RTU” devices and Ethernet “Modbus TCP” devices.
The D2 W MDME 2400 is available in two models with different RF power:
D2 W MDME 2400 1 100mW of RF power
D2 W MDME 2400 3 300mW of RF power
Note that European regulations do not permit more than 100mW of RF power to be used.
Operation in France, Italy, Luxembourg, Norway, and the Russian Federation is limited to
indoor use only. Refer to Appendix C for clarification. In the U.S., Canada, and
Australia, up to 1W of RF power may be generated. In other countries, please check with
your Cooper Crouse-Hinds representative.
The D2 W MDME 2400 has a standard RJ45 Ethernet connection which will operate at up to
100Mbit/sec. The module will transmit the Ethernet messages on the wireless band at rates between
1 and 11 Mbit/sec.
1.1 Network Topology
The D2 W MDME 2400 is an Ethernet device, and must be configured as part of an Ethernet
network. Each D2 W MDME 2400 must be configured
as:
An “Access Point” or a “Client,” and
A “Bridge” or a “Router.”
Client
Ethernet
Device
Access
Point

IF 1584 Rev. 1 Page 6
You can also connect to the D2 W MDME 2400 via a RS232 or RS485 serial port using serial server
or PPP (point-to-point) protocol. PPP allows the D2 W MDME 2400 to connect serial
communications into the Ethernet network.
Access Point versus Client.
The Access Point unit acts as the “wireless
master” unit. The Access Point sets up the
wireless links to the Client units and controls the
wireless communications. The first diagram
shows two Ethernet devices being linked. One
D2 W MDME 2400 is configured as an Access
Point and one as a Client - in this example, it doesn’t
matter which unit is the Access Point.
The second diagram shows an existing LAN being
extended using D2 W MDME 2400s. In this
example, the Access Point should be configured at
the LAN end – although, the wireless link will still
work if the Client is at the LAN end.
An Access Point can connect to multiple Clients. In
this case, the Access Point should be the “central”
unit.
An Access Point could be
used as a “Repeater” unit
to connect two D2 W
MDME 2400 Clients
which do not have direct
reliable radio paths.
Multiple Access Points can be set up in a “mesh” network to provide multiple repeaters.

Bridge versus Router.
Each D2 W MDME 2400 is configured with an IP address for the Ethernet side, and another for the
wireless side.
A Bridge connects devices
within the same Ethernet
network - for example,
extending an existing Ethernet
LAN. For a Bridge, the IP
address for the wireless side is
the same as the Ethernet side.
A Router connects devices on different LANs. The IP addresses for the Ethernet and wireless sides
are different.
In the above example, the
wireless link is part of LAN A,
with the Client unit acting as a
Router between LAN A and
LAN B. Alternatively, the
Access Point could be
configured as a Router - the
wireless link is then part of
LAN B.
If more than two Routers are required within the same radio network, then routing rules may need to
be configured (refer to Section 3.11, “Routing Rules,” for further details).
There is no limit to the number of Bridges in the same network – although, there is a limit of 128
Client units linked to any one Access Point.

1.2 Getting Started Quickly
Most applications for the D2 W MDME 2400 require little configuration. The D2 W MDME 2400
has many sophisticated features; however, if you don’t require these features, this section will allow
you to configure the units quickly.
First, read Section 2, “Installation.” The D2 W MDME 2400 requires an antenna and a power
supply.
Power the D2 W MDME 2400 and make an Ethernet connection to your PC (for further
information on how to do this, refer to Section 3.4).
Set the D2 W MDME 2400 address settings as per Section 3.4.
Save the configuration - the D2 W MDME 2400 is now ready to use.
Before installing the D2 W MDME 2400, bench test the system. It is a lot easier to locate problems
when the equipment is all together.
There are other configuration settings which may or may not improve the operation of the system.
For details on these settings, refer to Section 3.

Chapter Two Installation
Page 9 November 2008
Chapter Two INSTALLATION
2.1 General
The D2 W MDME 2400 module is housed in a rugged aluminium case, suitable for DIN rail
mounting. Terminals will accept wires up to 2.5 sqmm (12 gauge) in size.
All connections to the module must be SELV. Normal 110-250V mains supply should not
be connected to any terminal of the D2 W MDME 2400 module. Refer to Section 2.3,
“Power Supply.”
Before installing a new system, it is preferable to bench test the complete system. Configuration
problems are easier to recognize when the system units are adjacent. Following installation, the
most common problem is poor communications caused by incorrectly installed antennas, radio
interference on the same channel, or the radio path being inadequate. If the radio path is a
problem (i.e. path is too long or obstructions are in the way), then higher performance antennas
or a higher mounting point for the antenna may rectify the problem. Alternatively, use an
intermediate D2 W MDME 2400 module as a repeater.
The foldout sheet D2 W MDME 2400 Installation Guide provides an installation drawing
appropriate to most applications. Further information is detailed below.
Each D2 W MDME 2400 module should be effectively earthed via the "GND" terminal on the
D2 W MDME 2400 module - this is to ensure that the surge protection circuits inside the D2 W
MDME 2400 module are effective.
2.2 Antenna Installation
The D2 W MDME 2400 module will operate reliably over large distances. The distance which
may be reliably achieved will vary with each application - depending on the type and location of
antennas, the degree of radio interference, and obstructions (such as buildings or trees) to the
radio path.
The maximum range achievable depends on the regulated RF power permitted in your country,
and whether you use separate transmit and receive antennas. With a single antenna, 5 km (3
miles) can be achieved in the U.S., Canada, and Australia (4W ERP), and 1 km in Europe
(100mW ERP). With separate transmit and receive antennas, more than 10 km (6 miles) can be
achieved in the U.S., Canada, and Australia, and more than 5 km in Europe.
To achieve the maximum transmission distance, the antennas should be raised above
intermediate obstructions so the radio path is true “line-of-sight.” The modules will operate
reliably with some obstruction of the radio path, although the reliable distance will be reduced.
Obstructions which are close to either antenna will have more of a blocking effect than
obstructions in the middle of the radio path. The D2 W MDME 2400 modules provide a
diagnostic feature which displays the radio signal strength of transmissions (refer to the
Diagnostics section for more information).

D2 W MDME 2400 Wireless Ethernet Modem IF 1584 Rev. 1
IF 1584 Rev. 1 Page 10
Line-of-sight paths are only necessary to obtain the maximum range. Obstructions will reduce
the range, however, may not prevent a reliable path. A larger amount of obstruction can be
tolerated for shorter distances. For short distances, it is possible to mount the antennas inside
buildings. An obstructed path requires testing to determine if the path will be reliable - refer to
Section 6 of this Instruction Sheet.
Where it is not possible to achieve reliable communications between two D2 W MDME 2400
modules, then a third D2 W MDME 2400 module may be used to receive the message and re-
transmit it. This module is referred to as a repeater. This module may also have a host device
connected to it.
The D2 W MDME 2400 unit has two antenna connections at the top of the module, allowing two
antennas to be fitted to the unit. The left connector (looking at the front) labeled “RX” is
connected only to the internal wireless receiver. The right connector labeled TX/RX is
connected to both the transmitter and receiver.
Note: when only one antenna is used, it must be connected to the right TX/RX connector.
Plant and Factory Installations.
Most installations in industrial plants and factories use single omni-directional antennas.
Installations can suffer from “multi-path fading” effects where multiple reflected radio signals
adversely affect the signal strength. This can be checked by moving the antenna a short distance
(10 cm or 4 inches) - if the signal increases significantly, then there are multi-path effects.
In a “static” installation, where the radio path is not changing, moving an antenna to the position
of maximum signal solves this problem. However, where the radio path changes because the D2
W MDME 2400 is mounted on moving equipment, or if there is moving equipment in the area,
then the solution is to use two antennas. Because the two connectors are separated, the RF signal
at each connector will be different in the presence of multi-path fading. The D2 W MDME 2400
unit will automatically select the higher RF signal.
Note that directional antennas are not normally used in plant and factory installations.
Line-of-sight Installations.
In longer line-of-sight installations, the range may be increased by using a high gain antenna on
the TX/RX connector. However, the gain should not cause the effective radiated power (ERP) to
exceed the permitted value. A second higher gain antenna can be connected to the RX connector
without affecting ERP - this will increase the operating range, provided the background noise in
the area is low.
Antennas.
Antennas can be either connected directly to the module connectors or connected via 50 ohm
coaxial cable (e.g. RG58 Cellfoil or RG213) terminated with a male SMA coaxial connector.
The higher the antenna is mounted, the greater the transmission range will be; however, as the
length of coaxial cable increases, so do cable losses.
