06 Logging - Performance Box Touch V1


Performance Box Touch V1 logs data via an SD card inserted into the SD cad Slot on the left-hand side of the unit. Depending on the Logging Strategy you have selected in the General Settings area, the unit will either log continuously or when it detects movement.
You can manually override the configured logging strategy by tapping on the SD Card Icon when it is green to start or stop the logging. VBOX Touch SD OK.png

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, you must press the SD Card Icon to stop the logging before you remove the SD card.

Sometimes, due to poor satellite visibility, for example in a garage or close to a building, the box may start recording even if the car is stationary. Always check the Record Icon to make sure the box is not recording before you eject the card.

The SD card should not be removed when the Record Icon flashes red as it may cause you to lose data.

Note: If the SD card is removed while the box is still recording, you may need to repair it on a PC before you can use it again.

SD Card Format

Performance Box Touch is supplied with an 8 GB SDHC card in a FAT32 file format, which is the only file format it supports.

If you are looking to purchase a new SD card, we recommend that any card you use has a write speed of above 7 MB/s (4 MB/s is the absolute minimum) and a speed class of 10 (4 is the absolute minimum). We recommend that you use SD cards from quality brands such as Transcend, SanDisk, Kingston or Lexar to ensure the best results.

If you have an SD card that is formatted in the exFAT or NTFS file formats, you will have to reformat it to a FAT32 file system before it will work with a Performance Box 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 Performance Box 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 Performance Box Touch. Please reformat as per the instructions below.

SD Card Reformatting

  • FAT32 reformatting for media with sizes up to 32 GB can be done directly in 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, you cannot do it directly in Windows as it is not the standard formatting for the file. However, there are many third-party software programs you can use to reformat media so that they will work correctly with our products - we recommend  This Tool as a free option from the SD card organisation.

Logged Channels

Performance Box Touch logs channels to a .vbo file on an inserted SD card. The channel information is as follows:

  • Satellites: This is the number of satellites in use.
  • Time: This is UTC time 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 with respect to North.
  • Height: Height above sea level in meters based on the model of the earth used by thye 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 = SBAS.

  1. Performance Box Touch has an internal patch antenna, meaning that in many circumstances, where the unit has a clear view of the sky without any interference, an additional antenna is not required.

    However, if required, mount the external GPS antenna (RLACS284) in the centre of the roof of the vehicle, away from roof bars and other antennas. For more information on antenna mounting positions click here.


  1. If applicable, connect the external GPS antenna to the Performance Box Touch.
  2. Connect the Battery (RLACS290) if required. For more information on the battery click here.
  3. Connect the Swivel Neck Richter Suction Mount (RLACS277) to the rear of the unit or battery and attach to the vehicle windscreen. For more information on mounting click here.
  4. Connect the power via the Power socket, or if using the battery independent of a power source, press and hold the Power button on the battery for a few seconds.
  5. Insert the SD card into the Side of the Unit. The SD Card Icon should display as green VBOX Touch SD OK.png as long as the card has free space.
  6. When the unit has booted, select the Mode Button Mode.png and press DECEL if it is not already selected.

VBOX Touch Mode Decel2.png

  1. Select the Settings Button Settings.png, then the Decel option and choose from either a Preset Test, or use Custom Start and End Parameters.

  1. Press the Exit Button Exit Screen.png to return to the Decel Test screen.


  2. Take the vehicle outside and wait for the Performance Box Touch to gain satellite lock. The Satellite Icon should display as solid green VBOX Touch Sats Lock.png.

    Note: 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.

  3. The unit is now ready to display live Decel Test results.

  4. By default, Performance Box Touch will automatically start recording when travelling over 0.5 km/h, this can be changed within the General Settings.
  5. Tapping on the SD Card Icon when green VBOX Touch SD OK.png will manually start or stop logging data, overriding the Configured Logging Strategy.
  6. The Record Icon VBOX Touch Recording Button.png 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 – The SD card shouldn't be removed when the Record Icon is on as you may lose data.

    Note: If for some reason the SD card is removed whilst still recording, it may need to be repaired using a PC before it can be reused.



  7. A screenshot of what is displayed on the screen can be taken at any time by pressing the Screenshot Button  Screenshot.png.

  8. To reset all test results shown on the current screen, press the Reset Button Reset.png.

  9. When you have finished your testing, completed test results can be viewed by pressing the Results Button Results.png.
