Power Supply

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 guidance

IMPORTANT

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 25 Hz GPS Speed Sensor (v2) 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.

Installation

Mounting

The VBOX 25 Hz Speed Sensor should be secured inside the vehicle to stop it from moving when the vehicle is in motion.

The base plate has M3 screw holes along its length that you can use if you want to bolt it directly to a mounting surface in the vehicle.

Alternatively, the Racelogic Mounting pole is compatible so you can mount the unit vertically. Contact vbox@racelogic.co.uk for more information or to order a mounting arm (RLACS212-V2) and/or mounting bracket (RLACS291).

Antenna Placement

Appropriate placement of the GNSS antenna is crucial to the quality of the data that is being recorded.

Be aware of objects that can shadow the antenna or block the signal to the antenna. Some objects can also reflect signals which can send weaker GNSS signals to the antenna. This is called multipath, and these reflections can disturb the signal in an unpredictable way.

If an antenna is not mounted on a large enough ground plane, multipath reflections can also come from the ground beneath the antenna.

Note: You can find in-depth information about how to place the antenna on a vehicle and how to use the satellite elevation mask here.

Hardware Connections

Note: You can find more information about the cable loom and the connector labels here.

Connecting the Loom to the VBOX Unit

Note: It is important that you do not use force when connecting and disconnecting the loom to the VBOX unit.

Look at the connectors on both the loom and the unit.	Locate the different-sized inner notches on the loom's connector and line them up with the equivalent notches on the unit's connector.	Note the outer notches on the connector.

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.

Front Panel

VBOX Setup

An overview of how to use the VBOX Setup Software to configure your VBOX 25 Hz Speed Sensor (v2).

Introduction

This is a general overview of the VBOX Setup software, connected to the VBOX 25 Hz Speed Sensor (v2), 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.

Connection

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

You must use the VBOX Setup software to configure the unit. Use the supplied loom, connect the SERIAL lead and connector to the computer's serial port – you can also use a serial-to-USB converter if necessary.

IMPORTANT
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.

Note: An auto-detect message may appear if the baud rate has been changed from the default value - select ‘Yes’ to allow the different baud rates to be scanned.
