Dear Reader
You are holding in your hand the fifth edition of the Westermo Handbook. The first
edition of the Handbook was printed ten years ago in 1994 and has over the years
become a tool used by engineers and others who have an interest in data communi-
cation.
As in the previous editions our goal has been to give not only an in-depth presenta-
tion of the Westermo product range, but also a comprehensive overview of the
most common theoretical aspects of data communication. The theoretical and gen-
eral application section has been increased in every new edition of the handbook
and this fifth edition is no exception.
This edition of the handbook differs from the previous editions. Due to the huge
increase in our product range we have divided the handbook into sections to be eas-
ier to use.
The different sections are:
… Theoretical and general applications
… Remote Connection
… Industrial Ethernet
… Local Data Communication
Our hope is that the Westermo Handbook will become a useful tool to help you in
your everyday work and a supplement to the service and support provided by all the
dedicated people we have round the world.
