VOB / Introduction

VOB Introduction

  • Real time data overlaid onto video, both PAL and NTSC versions available
  • Real time lap and sector times without a track side optical beacon
  • User configurable display, with up to four screens of data (max 16 values per screen)
  • Compatible with the DL2, DL1, AX22 and SPEEDBOX products

What is the VOB?

The VOB is an optional “black box” module that works in conjunction with all our data logging products. It enables data to be overlaid onto a live video stream. The overlaid data can be either in the form of numbers, bar graphs, or a combination of the two. The data that is displayed as well as the format is controlled from a PC - just as it is for the DASH1. Warnings for high and low values on any channels are also displayed on the data, as well as sector times (hardware permitting). Characters are displayed as white text with a thin black outline, making them easily readable whatever background is present.

Who is the VOB designed for?

The VOB can be used as a simple data analysis tool for improving car or driver performance, in just the same way as a traditional data logger. The video information is an excellent way of presenting information in a very intuitive way and requires almost no skills from the end user. It enables easy checking of lap and sector times without the use of a computer for analysis. Typical applications include racing driving schools, driving experience days and presenting data in industrial applications.

What does the VOB do?

The VOB takes a standard serial stream from any of the Race Technology product range and overlays selected data onto a composite video signal. Typically, the video signal will be from a bullet camera mounted in the car, and recorded onto a portable video camera or a portable video recorder. The video stream can be either PAL or NTSC (must be specified at the time of ordering). The VOB can only be used in conjunction with our other data logging products to act as a source for the data; it can’t be used as a standalone device. The VOB can be powered either from the logging device, or where this is not possible, through an external 12V input.

to 16 variables can be displayed on the screen at the same time. In addition to these variables, all data is monitored against high and low limits, with warnings being displayed when these limits are exceeded. There is also a lap-timing feature, which will give sector and lap times along with a comparison to the best sector and lap time.

The VOB can be reprogrammed through the DL1, DL2, or AX22 making future upgrades and custom display settings a possibility.


  • 9 way d-type to accept power and serial data (leads available for AX22, DL1, DL2, SPEEDBOX)
  • Simple video in and video out connections (BNC connector)
  • Configurable from a PC
  • Up to 5 user configurable screens with values, bar graphs, or both.
  • Screens cycled through using push button on front panel
  • Data and power LEDs to show operation

The actual information that can be displayed depends on the hardware that the display is connected to:

GPS based Lap and sector times Yes Yes Yes -
Accelerations Yes Yes Yes Yes
RPM Yes Yes Yes -
Analogue channels (temperatures, pressures, etc) 16 8 - -
Frequency channels 4 4 - -
Speed Yes Yes Yes Yes
Position/Altitude Yes Yes Yes Yes


The data that is displayed can be controlled using the PC software provided, meaning that only the relevant data is visible and presented in the most helpful format. Using the software you can control:

  • Which channels are displayed
  • The name of the channels
  • The units displayed
  • The scaling of the channels
  • The number of decimal places displayed
  • Number of channels are displayed on the screen
  • Whether the channel is displayed as a value or bar graph
  • The lower and upper warning levels for the channels
  • How long lap and sector times are displayed for
  • How long warnings are displayed for
