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. Refer to Specific Conditions of Use.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
"Note that this unit can be connected to two different power sources."
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
When this unit is operated at an ambient temperature above +60°C (+140°F),
forced ventilation is required to not exceed Touch Temperature Limits according
to UL/IEC/EN 60950-1. A recommended airflow 32CFM (61m3/h) located 17cm
(7") below the unit is a minimum requirement. To reduce the risk of fire, use only
No. 26 AWG or larger telecommunication line cord.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not
waterproof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical
part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo
distributor office or Westermo Tech support.
A readily accessible disconnect device shall be incorporated external to the equipment.
This unit may have hot surfaces when used in high ambient temperature.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description
Functional description
The Wolverine DDW-142 allows effec tive Ethernet networks to be created over long
distances up to 15 km (9.3 mi) at data rates up to 15.3 Mbit/s on a single twisted pair
cable. By using two pairs “bonded” this rate can be doubled up to 30.4 Mbit/s. The integral
switch allows 2 Ethernet devices to be attached and an RS-232 port allows for a legacy
piece of equipment to be incorporated into the IP network.
The operating system in DDW-142 (WeOS) can deliver unique security functionality for
this class of product as well as allowing the DDW-142 to form part of a resilient multi-
media ring network using the Westermo FRNT protocol or industry standard STP/RSTP.
WeOS has been developed to provide industrial networking solutions and contains amaz-
ing serial connectivity capability – from being able to simulate an old AT modem, convert
Modbus RTU to TCP or encapsulate serial data into an IP packet.
The DDW-142 is incredibly flexible and easy to use. A basic point to point or multidrop
network can be created without the need for any kind of configuration. If however a more
complex solution requires some kind of network configuration the Web based setup is
simple to use. A CLI interface is also provided making the unit easy for networking pro-
fessionals to quickly master. Once the system is configured an easy solution is also avail-
able for the maintenance engineer – USB backup and restore means that stored configura-
tions can be automatically downloaded from a USB stick.
The DDW-142 is often used in applications on railways, roads or with utilities where fail-
ure could result in significant costs. All Westermo products are designed with high MTBF
in mind to improve operational reliability and also give long service life. Even features
like the SHDSL diagnostics and management allow indication of line degradation allowing
planned main tenance. As the unit is designed for these applications Westermo also ensure
that testing is carried out to ensure the unit can operate at extremes of temperature,
EMC and vibration and still provide robust communications.
