Introduction

This article focuses on how to send CAN data from Komodo Due interface channel A and monitor it in channel B of the same Komodo interface. In this example, one computer is used, since the Komodo interface has one USB interface for connecting to the computer.

Overview

In this article Komodo channel A is connected to Komodo channel B. Komodo channel A sends 11 22 33 44 55 and Komodo channel B monitors it.

CAN Data Transfer Guidelines

1. Download and run the latest version of the Total Phase USB Drivers Installer.
2. Download and unzip the latest version of Komodo GUI on PC. (?)
3. Download and unzip the latest version of Data Center on PC. (?)
4. Connect Komodo to PC via the USB connector.
5. Connect the Komodo DB-9 connector channel A to Komodo DB-9 connector channel B. (?)
6. Connect 1K OHM resistor between CAN+ and CAN- in Komodo channel A block screw terminal.
7. Launch Komodo GUI on PC. (?)
8. Launch Data Center on PC. (?)
9. Connect Komodo port 0 to Komodo GUI. (?)
   1. Click Analyzer.
   2. Click Connect.
   3. Select the Komodo port 0.
   4. Click OK to connect to the Komodo interface.
10. Connect Komodo port 1 to Data Center. (?)
    1. Click Analyzer.
    2. Click Connect to Analyzer.
