Power Supply

VBOX 100 Hz Speed Sensor units are powered via the POWER IN lead or the CAN OUT + POWER lead on the supplied loom. You can use the RLCAB010LE cable to connect to a 12 V ouput point in a vehicle or you can use a battery pack (RLACS333-L).


  • The maximum operating voltage input must not exceed 30 V DC. Failure to observe this could result in damage to the VBOX unit.
  • The cable looms and unit connectors are colour coded. It is important that you use a loom with a colour marker that corresponds with the colour marker on the unit's connector. The VBOX 100 Hz GPS Speed Sensor (v5) has a yellow colour marker. 

VBOX Speed Sensors have been designed to generate as little heat as possible and has a wide operating temperature range. It is, however, good practice to mount it in a position where it has sufficient airflow around the unit.

 You can find more information about the cable loom in the complete user guide.


When installing the VBOX 100 Hz GPS Speed Sensor (v5) in your vehicle, you can either fix it rigidly to the vehicle using the fixing holes or secure it with a telescopic mounting arm.

Try to position the unit as close to the centre of the vehicle as possible, and make sure that it is level with the ground. 

Note: The VBOX unit and the antenna should be mounted on the same rigid body to provide a relative reference. So for a vehicle such as a truck cabin, both the VBOX unit and the antenna should be fitted to the cabin body (if the cabin is air-sprung) or to the vehicle chassis.

Push the connectors gently together and twist the outer ring on the loom's connector until it slots in place and locks the connection. 
Disconnecting the Loom From the VBOX Unit

Note the notches on the connectors as illustrated above. Twist the loom's connector while you gently pull it away from the unit.

You can find more details about how to mount and connect your VBOX Speed Sensor and antenna in the complete user guide

Configure your Speed Sensor with VBOX Setup
An overview of how to use the VBOX Setup Software to configure your VBOX 100 Hz Speed Sensor (v5).

This is a general overview of the VBOX Setup software, connected to the VBOX 100 Hz Speed Sensor (v5), and its functionality. You can use the VBOX Setup Software to configure your VBOX unit. It provides greater functionality in comparison to using the Front Panel.


To configure a VBOX Speed Sensor unit, it needs to be connected to a power source and a computer.

Configuration is performed using VBOX Setup Software, which can be downloaded here. Using the supplied loom, connect an RLCAB001 cable to the SERIAL lead and connect the serial plug to the computer's serial port – this can be done via a serial > USB converter if required.

Microsoft Windows 7 
SP1 or newer is required (must be compatible with .Net Framework 4.7.1)

Once physically connected and powered, open the software and use the drop-down list to select the correct COM port that your VBOX unit is connected to. VBOX Setup automatically connects to the selected device and enters the setup screen for your unit.
