Support Question the of Week: Send and Monitor CAN Interface Channels with Komodo Interface

Q: I'm looking to use two Komodo Duo Interfaces to send and monitor CAN data on two separate computers, and I'd like to use Komodo GUI software to send data and Data Center Software to monitor the data over CAN interface channels. Can you recommend how to set this up?

Thanks for your question! In the following example, two computers are used with one Komodo Duo Interface per computer. Channel A will be used from each Komodo Duo Interface. Note—the same setup can be used with two Komodo Interfaces connected to the same computer. For more details about this setup, please refer to our Support Knowledge Base.

Overview:

  • Komodo-1 channel A, on PC-1,  is connected to Komodo-2 channel A on PC-2.
  • Komodo-1 channel A sends 11 22 33 44 55 and Komodo-2 channel A monitors the data.

Instructions:

  1. Connect Komodo-1 to PC-1 via the USB connector, and connect Komodo-2 to PC-2 via the USB connector.
  2. Connect the Komodo-1 DB-9 connector channel A to Komodo-2 DB-9 connector channel A.
  3. Connect 1K OHM resistor between CAN+ and CAN- in Komodo channel A block screw terminal.
  4. Launch the Komodo GUI software on PC-1.
  5. Launch the Data Center software on PC-2.
  6. Connect Komodo-1 port 0 to the Komodo GUI software. To do so, on the GUI panel:
    1. Click "Analyzer".
    2. Click "Connect".
    3. Select the Komodo port 0.
    4. Click "OK "to connect to the Komodo interface.
  7. Connect Komodo-2 port 0 to the Data Center software. To do so, on the Data Center panel:
    1. Click "Analyzer".
    2. Click "Connect to Analyzer".
    3. Click "OK" to connect to the Komodo interface.
  8. Configure the Komodo GUI software on PC-1:
    1. Click Mode ➝ General CAN.
    2. Enable "Active CAN Mode". Configure to Bitrate: 125 Khz, CAN ID: 0x123, DLC: 5, Message: 11 22 33 44 55, Ch A.
    3. Click Analyzer ➝ Run.
  9. Configure the Data Center software on PC-2:
    1. Click Analyzer ➝ Device Settings ➝ CAN.
    2. Disable "include packets from this device." Disable Monitor Bus B.
    3. Enable Monitor Bus A, Make Active Node, and Configure Bus A Settings.
    4. Disable Target Power. Configure to Bitrate: 125000. Disable Enable GPIO Configuration.
    5. Click Analyzer → Run Capture.
  10. On the Komodo GUI software click "Send Message".
  11. Verify that Komodo-1 sends the data correctly (see Figure 1), and that Komodo-2 monitors the data correctly (see Figure 2).
