VB2SX User Guide Operation Display Screen The Display screen will display data when operating it also displays all the menus required to configure the VB2SX via the front panel controls. On start-up, the display screen shows the unit’s firmware version. During normal operation, the display screen displays Speed (mph or km/h) and the logged file name, as well as the number of satellites that the VB2SX has locked on to. There are also two satellite status displays.
VB2SX User Guide Front Panel Controls The VB2SX can be configured using the front panel buttons, which enables configuration without the need for a computer. From the main screen, press the’■’ button to enter the configuration screen. Once in the configuration screen, press the ‘◄’and ‘►’ buttons to highlight the next or previous choice in any menu, and press ’■’ to select the highlighted option.

VB2SX User Guide Memory Cards The VB2SX stores logged data onto SD Cards. The supplied SD cards are already optimised for use on the VB2SX and as such do not need formatting before use. Should the SD Card need formatting due to card errors it should only be formatted using the ‘Format Compact Flash’ option in the VBOXTools software. The SD Card will need to be inserted into an SD Card reader (or a VB2SX set to ‘Card Reader’ USB Mode) for this to work.
VB2SX User Guide GPS Antenna The GPS Antenna supplied with the VB2SX is a 3.5v active antenna. For the best possible signal quality, it is important to maintain a clean connection between the antenna and the VBOX. Before fixing the antenna to the VBOX, ensure that there are no dust particles in either connector. Replacement antennas are available by contacting your VBOX distributor. The antenna is a magnetic mounting type for quick and simple mounting to the vehicle roof.
VB2SX User Guide DIGITAL and ANALOGUE OUTPUTS The digital outputs on connectors OUT1 and OUT2 are a frequency/pulse output corresponding to velocity, long ACC and Lat ACC. The frequency range is adjustable in software or via the front panel controls. The analogue outputs on connectors OUT1 and OUT2 output a 0V to +5V DC signal corresponding to velocity and a -5V to +5V signal corresponding to Long ACC and Lat ACC. The volts range is adjustable in software or via the front panel controls.
VB2SX User Guide Digital Inputs The DIGITAL I/O socket contains the two digital inputs for the VB2SX. Digital input 1 is also referred to as the Brake trigger input. This input is connected to an internal timer capture module that is able to record precisely an event time for use in brake distance calculation. This period of time is called the trigger event time, and is logged as the value in milliseconds between the trigger event and the last GPS sample.
VB2SX User Guide CAN / RS232 Ports / USB The VB2SX is equipped with a CAN Bus interface, a RS232 serial port and an USB port. The RS232 port or USB is used for all communication between the VBOX and laptop PC. The USB or RS232 ports are able to transmit live data from the VBOX to the PC for viewing and performing real-time tests. Note only the USB port is used for firmware upgrading The CAN Bus port is available in either the socket labelled CAN or the socket labelled Serial.
VB2SX User Guide Using the USB cable The first time you use the USB cable, you will need to follow the instructions below. Connect the USB cable between the VB2SX and your computer. Your computer will now recognise the presence of a new device, after a period of time a ‘Found New Hardware Wizard’ window will appear. See below.

VB2SX User Guide 7. Connect the power cable/ battery pack to the VBOX 8. If using 12v power cable, connect to vehicle 9. See below 9. With the power applied, the Display screen will illuminate. The VB2SX will start searching for satellites. The ST led will indicate the number of satellites currently in lock. For best results ensure the VBOX has acquired a lock on 5 or more satellites, essential for quality signal reception.
VB2SX User Guide VB2SX ‘.VBO’ file format The VB2SX data files are saved in standard space de-limited text format. This allows the data to easily be imported into third party applications such as word processors or spreadsheets. The files each contain a header section before the main data that describes the channel content and information about the VB2SX such as serial number and firmware version. The [Column names] parameter specifies the data in each column of the data section.
VB2SX User Guide VBOXTools Software The VBOXTools software is used for configuration of the VB2SX and also for analysis of the VBO data files. For further information on the VBOXTools software refer to the VBOXTools Software manual supplied with VB2SX.
VB2SX User Guide Upgrading the Firmware Occasionally Racelogic releases new versions of firmware code for VBOX products, this maybe to fix bugs or to add new features. New firmware for the VB2SX is loaded into the unit using a computer and the supplied USB cable.
