3. Product Description
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 DDW002-
B1 devices is capable of bridging high bandwidth Ethernet traffic over 2-wire cables, even
when there are corroded connectors. 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.
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.

4.5. Replacement of Product
Disconnect all cables and unscrew the product from the wall. MTTR (Mean Time To
Repair), i.e. time for replacement of product is < 10 minutes.
4.6. EN 45545-2 Mounting Notes
Two product can be mounted together and as a single interior non-listed group in the
sense of EN 45545-2 definitions. For multiple product, the spacing requirements for
interior non-listed groups must be met.
4.7. Getting Started
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.
1. Connect the cable (twisted pair or parallell cable) to X2 pin 1 and 3 (polarity
independent).
2. Connect Ethernet to the X1 port on the front of the DDW-002-B1.
3. 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.
