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
- If the vehicle includes an odometry sensor, you cannot use this procedure. See the instructions for Calibrating the Navigator box for use with an odometry sensor.
- Stop the vehicle, but keep the engine running.
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.
The main window and Login dialog box appear.
- In the Login dialog box, select the Navigator box’s COM Port from the drop-down list, then click Connect.
- From Display X of 64 samples, select 1.
.The Options window appears.
In the Options window, enter the following, then click
- 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.
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 , and connect to the Navigator box’s COM Port.
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.
Name the file, click GO, then start driving as
- Speed up gradually for 10 seconds until you reach approximately 40 km/h (25 MPH).
- If available, activate the vehicle’s cruise control.
- Drive at a constant speed for 10 seconds.
- 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.
