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 output point in a vehicle or you can use a battery pack.

#

VBOX 25 Hz Speed Sensor units is powered via the POWER IN banana plugs. Alternatively, you can use the CAN OUT + POWER lead on the loom to pass power to the Speed Sensor from a third-party device. Contact Racelogic Support for further guidance.

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.

When installing a VBOX Speed Sensor 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.

This is a general overview of the VBOX Setup software, connected to a VBOX Speed Sensor, 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.  

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.
