Chapter 1. Introduction
1.1 INTRODUCTION
The CAN BUS Analyzer Tool is intended to be a simple-to-use, low-cost CAN Bus
monitor which can be used to develop and debug a high-speed CAN network. The tool
features a broad range of functions which allow it to be used across various market
segments including automotive, marine, industrial and medical.
The CAN Analyzer tool supports CAN 2.0b and ISO 11898-2 (high-speed CAN with
transmission rates of up to 1 Mbit/s). The tool can be connected to the CAN network
using the DB9 connector or through a screw terminal interface.
The CAN BUS Analyzer has the standard functionality expected in an industry tool
such as trace, transmit, trace filter, log file capability, and group CAN message transmit.
All of these features make it a very versatile tool, allowing fast and simple debugging
in any high-speed CAN network.

1.3 OVERVIEW OF THE CAN BUS ANALYZER
The CAN BUS Analyzer provides similar features available in a high-end CAN network
analyzer tool at a fraction of the cost. The CAN BUS Analyzer tool can be used to mon-
itor and debug a CAN network with an easy-to-use graphical user interface. The tool
allows the user to view and log received and transmitted messages from the CAN BUS.
The user is also able to transmit single or periodic CAN messages onto a CAN BUS,
which is useful during development or testing of a CAN network.
Using this CAN BUS Analyzer tool has many advantages over the traditional debug-
ging methods embedded engineers typically rely on. For example, the tool trace win-
dow will show the user the received and transmitting CAN messages in an easy to read
format (ID, DLC, data bytes and timestamp).
