1 INTRODUCTION

The following user manual describes architecture, functionality, and configuration parameters
of the Wi-Fi 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 ether
directly over the Wi-Fi connection or indirectly over the LAN, 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 1.xx.
Updates specific to the user manual are done by adding letters: A, B, …, Z to the user manual
version number.
