INTRODUCTION

The following user manual describes architecture, functionality and configuration parameters of
the Ethernet to CAN Converter. It also contains technical specifications and installation
instructions of the converter.

The user should check whether the application firmware installed in the converter is covered
by this user manual. It can be done using any web browser connected to the converted over
the Ethernet connection, see:

Configuration Parameters

section for more details.

The user manual is valid for application firmware with the same major version number as the
user manual. For example, this user manual is valid for any application firmware version 5.xx.
Updates specific to the user manual are done by adding letters

: A, B, …, Z to the user manual

version number.
