AutoVu™ Navigator box Technote

SharpX X1S, X2S, XSU

After you have connected the vehicle's odometry to either the NAV port on the LPR Processing Unit or to the external Navigator box, you must install Genetec Patroller™ on the in-vehicle computer and complete the recommended pre-calibration tasks before you can successfully calibrate the system.

Before you begin

Install the Navigator box.

What you should know

You can find the drivers for the external Navigator box and GPS Antenna in the Genetec Patroller™ installation folder under ...\Drivers\AutoVu Navigator.


  1. Install AutoVu Patroller on the in-vehicle computer.
  2. Find the COM Ports of the Navigator box and its GPS receiver.
    You’ll need this information to log on to the Navigator oscilloscope tool, and to enter in Genetec Patroller™ Config Tool.
    1. Go to Windows Device Manager, and expand Ports (COM and LPT).
    2. Look for the following information:
      Navigator box port
      Seen by Windows as Silicon Labs CP210x USB to UART Bridge.
      GPS Receiver port
      Seen by Windows as u-blox 5 GPS and GALILEO Receiver.
      In the example below, the Navigator box is on COM Port 7, and its GPS Antenna is on COM Port 9.

  3. Turn on the GPS and Navigator box in Genetec Patroller™ Config Tool, then specify the COM Ports they are using as follows:
    1. Open Genetec Patroller™ Config Tool.
    2. Go to Navigation > Equipment, turn on GPS.
    3. Select Devices. The system will auto-detect attached USB devices.
    4. Select AutoVu™ Navigator - GPS from the list. The default values are correct for the operation of the Navigator box.
    5. Go to Navigation > Equipment and turn on Use odometry.
  4. Open the Navigator oscilloscope tool.
    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.
