Capturing a sample signal of your Genetec Patroller™ vehicle’s engine activity - SharpX X1S, X2S, XSU

AutoVu™ Navigator box Technote

SharpX X1S, X2S, XSU

To set the Navigator box’s sensitivity to noise, you must first capture a sample of the vehicle’s engine by performing three driving scenarios: accelerating from a complete stop, traveling at a constant speed, and then slowing down to a complete stop.

What you should know


  1. Stop the vehicle, but keep the engine running.
  2. Open the Navigator oscilloscope tool on the in-vehicle computer.
    NOTE: The Navigator oscilloscope tool is installed at C:\Program Files (x86)\Genetec AutoVu X.X\Tools. For Genetec Patroller™ versions earlier than 6.5 SR2, the oscilloscope is available on the USB key included with the Navigator box. The oscilloscope is also available on GTAP.
  3. Double-click Oscilloscope.exe.
    The main window and Login dialog box appear.

  4. In the Login dialog box, select the Navigator box’s COM Port from the drop-down list, then click Connect.
  5. From Display X of 64 samples, select 1.
  6. Click Tools > Options.
    The Options window appears.

  7. In the Options window, enter the following, then click Save:
    Capture time
    The duration of the sample capture. Best practice is a 30-second sample. For example, you can speed up for 10 seconds, drive at a constant speed for the next 10 seconds, then slow down to a complete stop for the last 10 seconds.
    Export capture to folder
    Specify where to save the sample file.
    NOTE: Do not adjust the Voltage scaling factor or the Odometry sensitivity settings.
  8. From the main window, click Start capture.
    The Capture session name dialog box appears.

    Tip: If the Start capture button is unavailable, it means you are not connected to the correct COM port. Go to File > Reconnect, and connect to the Navigator box’s COM Port.
  9. Enter a filename.

    The default filename is the current date and time (YYYY-MM-DD_hh-mm-ss). You can add to the name, or change it if you choose.

  10. Name the file, click GO, then start driving as follows:
    1. Speed up gradually for 10 seconds until you reach approximately 40 km/h (25 MPH).
    2. If available, activate the vehicle’s cruise control.
    3. Drive at a constant speed for 10 seconds.
    4. Slow down gradually for 10 seconds, until you come to a complete stop.


The 30 seconds capture ends. You have captured a sample signal of the vehicle’s engine.

After you finish

Analyze the sample signal.
