SD Card
VBOX Touch logs data to an SD card. Depending on the Logging Strategy that is set in the General Settings area, the unit will either log continuously or when movement is detected (default).
VBOX Touch is supplied with an 8 GB SDHC card in a FAT32 file format, which is the only file format supported.
If you are looking to purchase a new SD card, it is recommended that any card used has a write speed of above 7 MB/s (4 MB/s absolute minimum) and a speed class of 10 (4 absolute minimum). Racelogic recommends SD cards from quality brands such as Transcend, SanDisk, Kingston or Lexar to ensure the best results.
IMPORTANT
If an SD card is formatted in the exFAT or NTFS file formats, it will need to be reformatted into a FAT32 file system before it will work with a VBOX Touch unit.
SDHC cards (2 GB to 32 GB)
Supplied or purchased SDHC cards are formatted in the FAT32 file format. This format is supported by VBOX Touch.
SDXC cards (64 GB and above)
Purchased SDXC cards will be formatted in exFAT or NTFS file formats; these formats are not supported by VBOX Touch (please reformat as per instructions below).
- FAT32 reformatting for media with sizes up to 32 GB can be done directly within Windows by right-clicking on the media and selecting 'Format'.
- If you would like to format media with sizes above 32 GB into a FAT32 file system, this isn't something that can be done directly within Windows as it is not the standard formatting for the file. However, many third-party software programs can be used to reformat media to allow them to work correctly with our products - we can recommend This Tool as a free option from the SD card organisation.
Power
The VBOX Touch unit is powered by a power cable that is unterminated so that you can make a bare-wire connection to a power supply. The cable terminates in a 2-way connector that mates with the Power socket on VBOX Touch.
On boot-up, the VBOX Touch will display a splash screen and automatically look for satellites and media.
The first time that the unit is booted up, the Display Mode screen will be presented. Every time after this, the last used display mode will be opened.
Logging
VBOX Touch logs data via an SD card inserted into the side of the unit. Depending on the Logging Strategy selected within the General Settings area, the unit will either log continuously or when movement is detected (default).
Tapping on the SD Card Icon when green will manually start or stop logging data, overriding the Configured Logging Strategy.
The Record Icon will show when the unit is logging data to the SD card.
If you have come to a stop, but the Record Icon is still on, press the SD Card Icon to stop the logging before removing the card.
Sometimes, due to poor satellite visibility in a garage or close to a building, the box may start recording, even if the car is stationary. Always check the Record Icon before ejecting the card.
IMPORTANT
Do not remove the SD card when the Record Icon is on as you may lose data.
Note: If for some reason the SD card is removed while the unit is still recording, it may need to be repaired using a PC before it can be reused.
Logging Switch
You can also control the logging by using an RLVBACS010 hand-held latching trigger switch (unlatched for logging/ latched for not logging). Continuous Logging Mode should be selected when using the switch. It is connected to the 3-pin Digital In and PPS Connector on the side of the VBOX Touch.
When the trigger switch is connected and latched, it is not possible to use the SD Card Icon to manually start or stop logging data.
Logged Channels
VBOX Touch logs channels to an inserted SD card within a .vbo file, channel information is available below:
- Satellites: This is the number of satellites in use.
- Time: This is UTC since midnight in the form HHMMSS.SS.
- Latitude: Latitude in minutes MMMM.MMMMMMMM +ve = North e.g. 3169.30644410M = 52D, 49M, 18.4S.
- Longitude: Longitude in minutes MMMMM.MMMMMMMM +ve = West e.g. 00040.18164742M = 00D, 40M, 10.9S.
- Velocity: Velocity in km/h.
- Heading: Heading in degrees concerning North.
- Height: Height above sea level in meters based on the model of the earth used by VBOX GNSS engines.
- Vertical velocity: Vertical velocity in km/h. +ve velocity uphill, -ve velocity downhill.
- Long accel: Longitudinal acceleration in g, +ve for forward acceleration.
- Lat accel: Lateral acceleration in g, +ve for acceleration to the left.
- Solution type: Indicator for what the unit is currently using to derive position: 0 = No sats; 1 = Standalone using GNSS only; 2 = DGNSS.
- Event 1 time: This is the digital input oversample timer used to interpolate the trigger event time between captured samples.

Connectors
Antenna
If you are struggling to maintain a stable satellite lock, you can connect the supplied external antenna (RLACS262) to the antenna socket. You should also use the external antenna when you are doing Brake Trigger Tests. You can find more information about the external antenna further down on the page.

Left Side
|
D IN/PPS
The Digital In and PPS port can be used for connection to the VBOX Brake Pedal Trigger to provide brake trigger deceleration tests. More information on this is available here.
The port can also be used to connect a Hand Held Start/Stop Logging Switch (RLVBACS010) to control the logging of the unit. More information on this is available here.
|
CAN/Serial
The top CAN/Serial port can be used to output serial information, allowing you to either connect VBOX Touch to VBOX Test Suite via an RLCAB001 and conduct live testing, or output lap timing parameters. You can find more information about the Serial Output settings here.

Satellite Reception
VBOX Touch has an internal patch antenna. This means that in most circumstances where the unit has a clear view of the sky and no interference, you do not need an additional external antenna. However, if you are struggling to maintain a stable satellite lock (indicated by a flashing red satellite icon), you can use the external antenna (RLACS262) supplied with the unit.
IMPORTANT
- If you are conducting Brake Trigger Deceleration Tests, you should use the external antenna.
- The first time that the unit is used, it may take up to 10–15 minutes to fully acquire satellites. After this, it will usually take 1–2 minutes to acquire satellites.
External Antenna (If Required)
The placement of the GNSS antenna is crucial to the quality of the data recorded by VBOX Touch. Any metal close to a GNSS antenna can unpredictably disturb the signal due to interference from reflections of weak GNSS signals.
For the best results, use the antenna in the centre of a metal roof at least 5 cm away from any roof bars or radio antennas. Do not mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals. Avoid the edges as reflections from the A-pillars will cause problems.
Mount the antenna as high up as possible and keep it above any roll bars. Pieces of metal close to and above an antenna will badly disrupt the GNSS signal.
If the vehicle being used does not have a metal roof, then place the GNSS antenna on a flat piece of metal at least 10 cm in diameter. If this is not possible, copper or aluminium foil can be used to create a shaped ground plane underneath the antenna. For example, on a fibreglass roof, mount the antenna on top of the roof, and place some adhesive-backed metal foil underneath, on the inside of the roof.
Acquiring Satellite Lock
Tall buildings or trees can block GNSS signals, causing a reduction in the number and quality of satellites being tracked, leading to inaccurate position measurements and a noisy velocity signal.
GNSS works best in open areas/ Avoid tree-lined roads
GPS Coldstart
If VBOX Touch is struggling to acquire a satellite lock, a GPS coldstart may be required. This may be necessary when the unit hasn’t been used for several days or has dramatically moved location since its last use.
To perform a coldstart, press the COLDSTART button within the Diagnostics Settings menu.
When the button has been pressed, the unit will make an audible sound and a ‘PLEASE WAIT’ message will be displayed on the screen which will count down from 3. The number of satellites will then be displayed as '00' and GPS status will show ‘SEARCHING FOR SATELLITES’ until the satellite lock has been acquired. It will take approximately 25 to 30 seconds for the unit to reacquire the satellite lock.
The 4 LEDs at the top of the unit provide visual feedback dependent on what process is being performed:
Function |
Behaviour |
Colour |
Accel/Decel Mode |
If Alert at End is enabled, the LEDs will flash green for 0.5 s once the test end criteria are met. |
|
Lap Timing Mode |
The LEDs provide a live reference lap speed comparison (Delta-V). |
|
|
The current lap is > 5 km/h quicker than the reference lap
The current lap is 2.5 km/h quicker than the reference lap
The current lap is the same speed as the reference lap
The current lap is 2.5 km/h slower than the reference lap
The current lap is > 5 km/h slower than the reference lap
|
|
The LEDs will illuminate blue during the process of creating a Reference Lap.
|
|
When loading a Track Database file, the progress of the track database update is displayed via the LEDs; each lit LED will represent 25% of the process with all LEDs extinguishing when the process is complete. |
|
When a Track Layout is changed, the LEDs will briefly flash green twice. |
|
When a Finish Line is cleared, the LEDs will briefly flash green twice. |
|
When a Standing Start is Enabled or Disabled, the LEDs will briefly flash green twice. |
|
