Extenders
Wolverine series –
Ethernet Extenders for Extreme Environments
The Wolverine series of SHDSL Ethernet extenders can be
used in point-to-point, daisy chain or ring applications. SHDSL
represents the best of several symmetric DSL technologies allowing transmission
distances of up to 10 km with data rates of up to 5.7 Mbit/s.
The technology we use makes the Wolverine series ideal
for transmitting Ethernet over long distances on legacy
copper cables.
The units will auto-negotiate the transmission speed, but
can also be forced to choose a slower (more reliable) or
faster (less reliable) data rate.
Total galvanic isolation and transient
protection are standard for all interfaces.
The line interfaces are also equipped
with extensive protection against
current and voltage surges. The units
are designed for extended temperature
operation, have dual power inputs and
can operate in extreme environmental
conditions. The built-in 4 port Ethernet
switch in the DDW-200 series makes it possible
to create a simple Ethernet network with no additional
network devices.
DDW-100
Ethernet SHDSL Extender
The DDW-100 is a plug and play Industrial Ethernet SHDSL extender. It is
designed as a transparent extender for 10/100BaseTX networks.
This unit provides the possibility to re-use existing twisted copper pair with
a high data rate at long distances.

Serial Adapters
EDW-100 / 120
Serial Ethernet Adapter
The EDWs allow devices with only a serial port to communicate over an
Ethernet network. They can be used either in point-to-point or point-to-multipoint
applications.
The EDW-100/120 are supplied with a software utility allowing 2 virtual COM ports
to be created on a PC. This software will redirect data, originally sent
to a local COM port, to the remote serial interface of the EDW-100/120 meaning
no changes are required to legacy applications. This makes it possible for “old” serial
devices to communicate on a standard Ethernet network thus removing the need to
maintain two different networks.
The EDW-100 has one serial port and EDW-120 has two.

Wireless Solutions
If the cost of wiring means that you cannot justify a project, then a wireless
connection could be the solution for the project to be approved. It could be long
distances where cabling is not even considered, or when there is an obstacle to
wiring – public roads, railway lines, tarmac, waterways etc. It is also a solution for
movable or moving equipment as well as temporary installations.
Using GSM/ GPRS gives you the possibility to connect to any serial device
worldwide. One condition is, however, that it is within the coverage area of a
GSM operator.
WLAN Access point and Client
The modems provide reliable and secure wireless connection between devices
with Ethernet or serial RS-232 / RS-485 interfaces. A line of sight distance of 1 km
(0.62 mi) is possible with the RM-240 and up to 5 km (3.1 mi) with the RM-80
and RM-90.

Routers
Remote connection to Ethernet Networks
General
A router is a device, or in some cases software in a computer, that determines
where a packet should be sent on its way to the end destination (the router is the
end destination from a LAN’s perspective).
Subsequently, the router is a network device that links together two or more
logically separate networks. It does not connect networks blindly, but acts more as
a packet switch and as a filter for the interconnection of local networks over short
or long distances.

The TD-23 can communicate via a 2- or 4-wire leased line according to the
V.23 standard.
The modem has DIP-switches allowing specific functions to be set, for example,
reception sensitivity, output signal level, etc. This is of particular importance as it
allows each modem to be optimized according to the line quality.
A general calculation allows 16 units over a distance of up to 25 km (15.5 miles).
Multidrop via dedicated lines
TD-29 is intended for half duplex communications via a 2-wire dedicated line.
The transmission distance and number of multidrop points are affected by the
number of connected modems and line quality. A typical value is 10 units up to
10 km (6.2 miles) at a transfer rate of 9600 bit/s. TD-29 is intended for use on
dedicated lines and must not be connected to general or leased telecom lines.
The TD-29P is designed to be used with PROFIBUS DP protocol.

it possible to transmit data up to 18 km (11.2 mi) at low data rates on a 4-wire
cable. At shorter ranges transmission rates up to 38.4 kbit/s can be achieved.
The LD-01 / 02 is also available in a ”by-pass” version. This model ensures that
if a modem in the multidrop network should fail that modem will be by-passed,
hence not effecting the communications between other units on the network.

LONWORKS®
Fibre optic solutions for LONWORKS® networks
These units are used to extend the transmission range between two or more
LONWORKS® networks on a single- or multimode fibre optic cable up to distances
of 20 km (12.4 mi). It can either be a point-to-point, multidrop or a redundant
ring solution. For point-to-point applications the PP-version is used. The modems
have an alarm output to indicate if any failure occurs on the fibre optic link.
Fibre Optic Repeater
The LRW-102 is totally transparent, which gives the advantage that no software
configuration via an installation tool is necessary, its just “plug & play”. Because of
the transparency the number of units in a multidrop or redundant ring installation
is limited to ten and a total distance of 20 km (12.4 mi) fibre link.

Fibre Optic
Fibre Optic cable has the advantages that it is completely insensitive to electrical
and magnetic disturbances. It is therefore ideal to install as a communication media

PROFIBUS DP
Solutions for PROFIBUS DP application
There are some limitations when using PROFIBUS DP because of its use of the
RS-485 electrical interface. One limitation is the transmission range, which is
limited to 200 m (0.13 mi) at 12 Mbit/s. The following products provide solutions
where pre-existing cables / networks (Ethernet) or even a wireless solution can
be used to link PROFIBUS DP networks. The FD-40 also allows an unintelligent
serial device to be connected to a PROFIBUS DP network.

Westermo Applications Story
Newcastle airport
Newcastle International Airport (NIA) is one of the United
Kingdom’s fastest growing regional airports and is the dominant airport in the North East of England. The airport handled over 68,000 flights and 5.2 million passengers in 2005.
Passenger satisfaction, safety and security are top priorities,
but in addition NIA is committed to environmental issues.
One important aspect of NIA’s Environmental Policy is to
ensure that contaminated surface water does not enter the
local watercourses. The Ethernet switch SDW-550 and the
Ethernet Extender DDW-100 are used to provide a reliable
data path between automated monitoring equipment and
a central Building Management System located in the main
terminal building.
High reliability fibre optic modems for
the Gotthard tunnel
The Gotthard tunnel is at the leading edge for traffic safety
and control. Weiss-Electronic, supplier of the traffic management system, chose Westermo’s fibre optic modems to
provide reliable communications to the 272 traffic lights
and 68 speed or emergency display screens.
Ethernet Switch used in Milking
Machine
The Astronaut milking robot, manufactured by Dutch company Lely Industries N.V., is sold worldwide in high volume.
The robot enhances productivity and service for farmers. It
uses Ethernet communications internally for efficiency, ease
of use and to reduce costs. As these robots are designed
to work 24 hours a day and 7 days a week, reliability was
a key issue, but it was also important to provide an optimal cost/function ratio hence Lely’s decision to use the
Westermo SDW-550 Ethernet switch.
Westermo Switches Used On Seattle
Bus
The ERG Group, a world leader in the development and
supply of integrated fare management and software systems
for the transit industry, have chosen Westermo Ethernet
switches to equip approximately 2500 buses operating
in the Central Puget Sound Region of Washington State,
around the city of Seattle. The new fare collection system
provided by ERG will collect upwards of $250 million in
annual passenger revenues from approximately 130 million
passenger journeys per year. Low operating voltage and
high reliability were the main criteria in the selection of the
Westermo Ethernet switches.

Westermo Applications Story
The decade’s most challenging gas field
operation
Ormen Lange, which is in the North Sea off the coast of
Norway (some 900 metres below the sea’s surface), will be
the second largest gas field on the Norwegian continental
shelf and will be a major new gas source for Europe beginning in 2007. Gas processing from Ormen Lange will take
place at Nyhamna in Mid- Norway and will be supplied to
the UK.
Westermo’s Ethernet switches have been chosen by
ABB to equip the fibre optics network of the Safety and
Automation System of Nyhamna’s on-shore plant. This unit
will be part of the processing plant for Ormen Lange gas
before it is exported to England.
Hardened Ethernet Switches Serving
the Environment
The Westermo Lynx range of Ethernet switches has been
selected to provide the network for the monitoring, control and supervision of the Seine Grésillons SIAAP (Paris
conurbation inter-departmental sanitation agency) plant in
Yvelines, to the west of Paris. This is a wastewater treatment plant opened in February 2007 designed to operate
with minimal manning levels. The Westermo switches have
made the difference, thanks to their performance in severe
environments, their reliability and their ring recovery time
of less than 20 ms.
Golden Environments & National Park
The marshland located in PARQUE NACIONAL
DOÑANA is one of Spain’s most ecologically important
sites and a major tourist destination. The park falls under
the responsibility of the Ministry of Environment & National
Parks.
The Ministry needed a method to monitor various different
environmental variables in the marsh to build a history of
its evolution, while minimizing the environmental impact.
The area is inaccessible due to natural obstacles, so the stations had to be self sufficient in terms of power supply and
maintenance.
OMRON provided the total solution using PLCs and
Westermo´s GSM modems and it was all powered by a
solar panel. The stations collect values such as water temperature, conductivity, level, turbidity as well as wind speed,
direction, rain level and vaporization. There is a central
monitoring system, which collects all this data by polling
each station via the GSM-modems.
