Sending CAN Messages From Komodo Duo Interface and Monitoring It With Another Komodo Interface Using Komodo GUI and Data Center

Introduction

This article focuses on how to send CAN data from one Komodo Duo interface (channel A) and monitor it in a second Komodo Duo interface (channel A). In this example, two computers are used with one Komodo interface per computer. However, the same steps can be used with both Komodo interfaces connected to a single computer.

Overview

In this article Komodo-1 channel A is connected to Komodo-2 channel A. Komodo-1 channel A sends 11 22 33 44 55 and Komodo-2 channel A 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-1. (?)
  3. Download and unzip the latest version of Data Center on PC-2. (?)
  4. Connect Komodo-1 to PC-1 via the USB connector. Connect Komodo-2 to PC-2 via the USB connector.
  5. Connect the Komodo-1 DB-9 connector channel A to Komodo-2 DB-9 connector channel A. (?)
  6. Connect 1K OHM resistor between CAN+ and CAN- in Komodo channel A block screw terminal.
  7. Launch Komodo GUI on PC-1. (?)
  8. Launch Data Center on PC-2. (?)
  9. Connect Komodo-1 port 0 to Komodo GUI. (?)
    1. Click Analyzer.
    2. Click Connect.
    3. Select the Komodo port 0.
