EX approved industrial Ethernet Extender 
DDW-142-EX
The Wolverine DDW-142-EX is an Industrial Ethernet Extender, powered by the Westermo WeOS network operating 
system. Independently tested for IECEX and ATEX by Baseefa the Wolverine is the perfect solution for hazardous area 
applications in any part of the world.
Westermo Ethernet extender technology based on SHDSL makes it possible to reuse many types of pre-existing copper 
cables which can lead to considerable financial savings when installing new systems. The Wolverine DDW-142-EX allows 
effective 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 30.6 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  WeOS (Westermo Operating Systems) has been developed to allow cross platform and future proof solutions. 
WeOS can deliver unique security functionality for this class of product as well as allowing the DDW-142-EX to form part 
of a resilient multimedia ring network using the  Westermo FRNT protocol or industry standard STP/RSTP.  WeOS has 
been developed to provide industrial networking solutions and contains amazing 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-EX is often used in applications on railways, roads or with utilities where failure 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 
maintenance. 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.
