Safety
Before installation:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only. The power supply wiring must be sufficiently
fused, and if necessary it must be possible to disconnect manually from all power
supply. Ensure compliance to national installation regulations. This unit relies on
convection heating. Make sure that it is installed so that the ambient temperature
is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also check chapter EN 45545-2 mounting notes.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from all power supply.
WARNING
Do not open connected unit. Hazardous voltage may occur within this unit when
connected to power supply.
Before powering-up, a protective earthing conductor must be connected to the
protective earthing terminal and have a cross-sectional area of at least 1.5 mm².
Note that this unit can be connected to two different power sources.
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord.

Description
Made easy for extending Ethernet
The Wolverine series consists of Ethernet extenders and bridges for propagating
Ethernet traffic over existing cabling. The Ethernet link can be allowed to be extended
over longer distances than possible with pure copper Ethernet and at data rates of up to
70 Mbit/s.
The DDW-002-B1 makes it possible to reuse many types of pre-existing copper cables
since it is based on power line communication (IEEE 1901). A network with the DDW-
002-B1 devices is capable of bridging high bandwidth Ethernet traffic over 2-wire cables,
even when there are corroded connector.s The powerline communication standard is
designed to establish a reliable communication link over both twisted pair and parallell
cabling.
This can lead to considerable financial savings when refurbishing a train with Ethernet
communication, as existing train couplers can be reused without the need for a costly
rebuild or even replacement. By simply installing a DDW-002-B1 on each side of the
coupler, a bridge connecting the Ethernet networks on each side is created. The fact that
no configuration is needed further contributes to the ease of use.
Designed for harsh industrial environments
The DDW-002-B1 has been thoroughly tested by certified labs to ensure its compliance
with the standard for electronic equipment used on rolling stock, the EN 50155. For
several characteristics, Westermo exceeds the requirements mandated by the standard.
Furthermore, the design is based on Westermo’s long experience within the rolling stock
market, which brings benefits such as vibration safe integrated connector threading, IP67
ingress protection with GORE-TEX® membrane to prevent condensation water build-up
and ultimately a high MTBF and long service life under the harshest conditions.
Meeting the requirements for rolling stock, makes the DDW-002-B1 also very well suited
for deployment in other applications with severe operating conditions and extreme
environments.

Connection of cables
Recommended tightening torque for the M12 connectors: 0.6 Nm
Note that unused connectors must be covered by a protective cap (delivered with the
unit), tightened to the specified torque, in order to fulfill the specified ingress protection
code.
Removal
Disconnect all cables and unscrew the unit from the wall. Time for replacement
< 10 minutes.
Cooling
This unit relies on convection cooling. Make sure that it is installed so that the ambient
temperature is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit.
EN 45545-2 mounting notes
Two Viper units can be mounted together and as a single interior non-listed group in the
sense of EN 45545-2 definitions. For multiple units the spacing requirements for interior
non-listed groups must be met.
Wall mounting
There are four 6 mm bore holes intended for mounting the unit. The unit can be

Getting Started
This product is an unmanaged Ethernet extender designed to propagate Ethernet traffic
over existing cabling.
The DDW-002-B1 is easy to use and install. The units work in a pair over existing copper
cabling infrastructure and automatically connect to each other when the remote device is
sensed over the interconnecting lines.
The installation procedure to get the application up and running is simple. Connect the
cable (twisted pair or parallell cable) to X2 pin 1 and 3 (polarity independent). Connect
Ethernet to the X1 port on the front of the DDW-002-B1. Connect power to the
devices.
The following settings are valid for the Ethernet interface:
… Ethernet Auto-negotiation enabled
… Auto MDI/MDI-X
… Auto-polarity enabled
The DDW-002-B1 will automatically detect the possible data rate to the remote device
(over the X2 - PLC interface ).
The link performance can easily be measured after the powerline link is established.
Different types of methods and tools can be used.
One example of recommended software for throughput testing is Iperf. Please refer to
Iperf user documentation for instructions of usage.
Note! If the PLC link is not established or the established data rate is not suffcient for
the application, the distance might be too long between the devices.
The device is an unmanaged unit. If data throughput performance needs to be adjusted or
if no powerline connection is established, check cabling between the devices.
Configuration
All necessary configurations are preconfigured from factory and no other changes in the
settings can be done.
