What is in the box? 

When you purchase a VBOX LapTimer (RLVBLAP-R) you will find the following items when you open the box:

Product Code Quantity Description
VBLAP02-R-V1 1 VBOX LapTimer Unit with connectors on the rear
RLACS262 1 GNSS Antenna
RLCAB14LE 1 Unterminated Power Cable
RLACS313 1 8 GB SD Card
RLACS359 1 Rear Connector Bracket Assembly
Optional Extras
Product Code Description
RLCAB010LE In-Car Power Supply
Power Supply 

Any suitable 12 V supply powers the  LapTimer. You must wire the unterminated end of the RLCAB014LE cable directly to a compatible power supply or to a connector that you can use with a compatible power supply. 

The power port is the top Lemo port on the unit. 

When you power up the LapTimer unit, the LEDs will light white and sweep through the LED array to indicate that the unit is powered and initialising.

Compatible Media

The LapTimers can record to MMC, SD, SDHC and SDXC media cards formatted in a FAT or FAT32 format.

SDXC cards will be formatted as exFAT by default, a format type not supported by LapTimers.  You can still use them, as long as you reformat them to FAT32 first. There are various free third-party applications available online to format SDXC cards.

No Media

If you do not have an SD card inserted in your VBOX LapTimer, it will show a No Media message while the vehicle is moving at speeds of 5 mph or less. This makes it easier for you to make sure that you have an SD card inserted before you start your logging.

LED Behaviour

This page contains information about the different LED behaviours of the VBOX LapTimer (RLVBLAP-R).
Delta-V LEDs

The LEDs on the front of the VBOX LapTimer indicate the Delta-V of your vehicle. 

Red LEDs indicate that the speed is slower than the reference point and green LEDs indicate that the speed is faster than the reference point. When the LEDs are off, they indicate that you are matching the reference lap speed. 
 

Note: Each of the LEDs on the unit represents 33% of the selected Delta-V range. 0 delta time is in the centre of the unit's LED array. 

When the LapTimer calculates that your current speed is slower than the reference lap, the 3 LEDs on the left will gradually light up red from the centre and out, 1 LED per 33% of the Delta-V Range set in the Predictive Lap Timing settings. 

When the LapTimer calculates that your current speed is faster than the reference lap, the 3 LEDs on the right will gradually light up green from the centre and out, 1 LED per 33% of the Delta-V Range set in the Predictive Lap Timing settings. 

LapTimer-V2_PredictiveLapTiming_-00.08 (86.2kmh).png

LapTimer-V2_PredictiveLapTiming_+00.04 (108kmh).png

 

Combo-G LEDs

While the screen still displays the Delta-T for each lap, you have an optional mode that takes over the function of the LEDs when you are using predictive lap timing.

If the Combo G is greater than a selected minimum threshold (50 % LED minimum %, 0.5 g default), the LEDs will light up various colours dependent on the maximum g threshold selected (1.0 g default).

  • The LEDs will show red where the Combo G has reached the LED minimum % selected (50% by default).
  • Above this minimum value, the LEDs will show a colour gradient between red and green, giving a changing yellow/orange colour, dependent on the live Combo G value.
  • The LEDs will show green where the Combo G is equal to or greater than the selected maximum g threshold.

You can change the settings for the Combo-G LED behaviour in the Predictive Lap Timing Menu.

Display Modes

This page provides a summary of all the display modes available on the VBOX LapTimer (RLVBLAP-R).

Logging 

If the LapTimer unit is logging, you will see a scrolling bar across the bottom of the screen (except in Predictive Lap Timing mode).

You can start and stop the data logging by pressing the OK button in the Speed Display mode.

 LapTimer-V2_Speed_47.92kmh.png

Display Modes 

The LapTimers have several different display modes, that you can cycle through with the up and down buttons on your unit.

Note: All the data options for the screens are always calculated by the unit at all times, even if you choose not to display it.

Click on the name of each mode to find relevant setup information. 

Predictive Lap Timing

Before using this mode, you need to set a start/finish line. Make sure that you have selected a track layout through the main menu or set a start line manually.

Before you cross the start/finish line, the screen will show Waiting for start line and the distance from your current location to it.

When you first cross the line and during the first lap, LapTimer will create a reference lap.

The second time you cross the start line, the LapTimer starts predicting.

If you set a new start/finish line while the LapTimer is logging, the Predictive Lap Timing mode will start recording a new reference lap.

 LapTimer-V2_PredictiveLapTiming_with bar_+05.53.png
Reference Lap

The reference lap will be replaced with any subsequent quicker lap time. However, you can fix a reference lap to prevent faster lap times from replacing it.  

Fix the reference lap time by pressing the OK button at any time during your lap. Pressing the OK button will either fix the lap you are currently driving or fix a lap saved in the memory. You can choose which one your LapTimer will use under Fixed Lap Mode in the Predictive Lap Timing Settings. 

Note: When you have fixed a reference lap, you will see a message confirming your selection on the screen and you will see a padlock icon in the top left corner.

  • If you fix a stored lap the icon will appear instantly. 
  • If you fix the current lap, the icon will appear when the lap you are currently driving has been completed. 

If you power-cycle the unit, clear the lap timing data or reset the start/finish, the fixed reference lap will be removed. If you wish to retain a fixed reference lap, make sure that the lap is saved to the SD card. You can then load it into the device when you need it.

 LapTimer-V2_PredictiveLapTiming_PressOKToFixComarisonLap.png
Clearing the Reference Lap 

If you need to delete the reference lap stored on your LapTimer unit, you can do this while in the Predictive Lap Timing Mode. Press and hold the OK button for 4 seconds. This will make the unit clear the stored reference lap and all lap timing data. 
Saving Reference Lap

This feature allows you to save a reference lap for future use. Insert an SD card into the VBOX LapTimer and use the following menu options:

Menu -> Predictive Lap Timing Menu -> Save Ref. Lap To SD Card -> OK button

Note: The vehicle must be stationary to make this transfer. 

You can read more about saving reference laps in the information about the Predictive Lap Timing Menu.

 VBOX LapTimers_PredictiveLapTimingMenu_SaveRefLaptoSDCard (v1.0 RE 25MAR2024).png
Load Reference Lap

To load a reference lap file stored from a previous session, you put the desired file onto an SD card and load the card into the VBOX LapTimer. The file can have any name, however, it must be saved in the Data folder and only one .REF file can be present. Select the menu options as shown above – but select LOAD REF LAP instead of SAVE. Note that the vehicle must be stationary to make this transfer. Reference laps will be reset either when you set a new start/finish is set, or if you select the ‘reset lap timing data’ option from the lap timing menu in the main menu. You can read more about loading reference laps on the Menu Options page.

You can create a reference lap with the Circuit Tools software as described here.

 VBOX LapTimers_PredictiveLapTimingMenu_LoadRefLapfromSDCard (v1.0 RE 25MAR2024).png
Live Timing

The main predictive lap timing screen shows a continuously updated time difference with the +/- to the reference lap. When a lap is completed, it will give a final lap time and total time difference to the reference lap. If you achieve a faster time than the reference, the time difference will be negative. 

You can also enable a Delta T bar graph in the settings and select the time shown on the bar graph ( 2, 5, 10 or 30 seconds). 

LapTimer-V2_PredictiveLapTiming_-00.08 (86.2kmh).png

LapTimer-V2_PredictiveLapTiming_with bar_+05.53.png

Lap Timing

All lap times and split times are interpolated to 0.01-second resolution.

  
Live Rolling or Static Lap Time 

In this mode, the screen can display either a live rolling lap time or a static last lap time and the lap count. You can change this in the Lap Timing Menu. 

LapTimer-V2_LapTiming_0.23..8_Lap02.png
Fastest Lap

The difference between the new lap time and the best lap time will be shown with a + or – sign. A ‘–’ is shown when a faster than best is achieved and a ‘+’ is shown for a slower than best.

 LapTimer-V2_LapTiming_Final time with delta_2.08.40 (-08.27).png
Split Line Display 

If you have set up split line in the Lap Timing menu, the LapTimer will display split times for 2-20 seconds when you cross the split line. Go to Menu -> Lap Timing Menu -> Split Time Display Period to set this up.
Setting Start/Finish Line

You can also set a new start/finish line while using the Lap Timing screen by pressing the OK button. If you do this by mistake, you can cancel the action by pressing the Down button within 5 seconds.

If you also require split lines or a separate finish, use the ‘set start and splits’ option in the Lap Timing Menu.

Note: The vehicle must be moving >10 km/h before you can set a Start/Finish Line.

When you set a new start/finish line, the unit will immediately start lap timing from where the new start line was set. If you cancel the setting of the new start/finish line, the LapTimer will retain the position of the old start/finish line and continue timing from that. 

Speed

In Speed mode, the screen will display a large clear speed value with up to 2 decimal places. You can set the speed to display in kph, mph or knots. You can adjust the number of decimal places displayed. For more information on how to change these settings, see here.

Note: To start or stop data logging on the VBOX LapTimer, press the OK button when in Speed Display mode.

 LapTimer-V2_Speed_47.92kmh.png

Max Speed

In max speed mode, the screen will show the highest achieved speed value to 0, 1 or 2 decimal places.

Note: If you press the OK button the unit will reset the displayed maximum speed value.

 LapTimer-V2_MaxSpeed_309.87kmh.png

Lap Count

The lap count screen will display 2 counters. On the left-hand side of the screen, you can see the total lap count – this counter can only be reset by a power cycle of the VBOX LapTimer. On the right-hand side of the screen, you can see the current laps. You can reset this by removing the logging media from the VBOX LapTimer.
