The VBOX Micro Input Module (RLVBMICIN01) is a small, highly cost effective module ideal for use in applications that only require a minimum of additional signals to be recorded, with one RPM (digital) input and four analogue inputs.
A 5v output is available to power sensors that are not already powered by the vehicle loom, and the analogue sensor range is from 0v to 14v.
It outputs data in either CAN or RS232 format depending on which device it is being used with.
The Micro Input Module is compatible with every VBOX data logger except VBOX Sport. Each Micro Input Module comes with a cable suitable for use with specific products.

small and rugged
Analogue Inputs (AN1 – AN4) 4 analogue inputs are included, which are capable of measuring 0 – 14.5V DC.
Digital Input (RPM) The RPM input connects to the low tension side of an ignition coil, enabling users to detect the RPM frequency. The input can process voltage spikes in excess of +/- 200V, and a maximum of 666Hz i/p frequency. The RPM input is a digital frequency input and is also capable of measuring digital signals such as 5V TTL and 0 - 12v digital pulse signals.
CAN Output (VBOX / Video VBOX) The analogue and digital signals are outputted via CAN when the Micro Input Module is connected to a VBOX. Note that CAN is output only – cannot take an input from Vehicle CAN.
RS232 Output (VBOX Mini / Performance Meters) VBOX Mini, DriftBox, and PerformanceBox utilise the RS232 output.
The high contrast OLED display is the perfect partner to your VBOX video logger.
Suitable even in bright conditions, the display provides sharp graphics and is simple to use. It can show a wide range of parameters, including live and max speed, lap times, and predictive lap timing.
The OLED display can start and stop logging in conjunction with some VBOX models, and also report logging status.
It is available in either a waterproof anodised blue aluminium case (RLVBDSP04), or a splash proof plastic and aluminium case (RLVBDSP05).

The OLED Display has an internal accelerometer that flips the screen in accordance with the way it is mounted, and can invert screen colours or display the font as a high contrast outline to match lighting conditions.
The OLED Display has different display modes, accessed using the Up and Down buttons. The data on each screen is calculated at all times, even if it is not currently displayed.
The Mini Input Module (RLVBMIM01) is a general purpose input/output module allowing you to data such as temperature, RPM, wheel speed, fuel flow, throttle angles and pedal forces to be easily measured along with the VBOX GPS data.
The module can accept 8 analogue inputs, 2 digital inputs, an additional digital state input for use as an event marker, and 2 K-type thermocouple inputs.
When used in conjunction with a VBOX Mini, the Mini Input Module can also output one digital and one analogue signal. Connections are via a removable screw terminal.
8 channel 16bit analogue inputs
2x K-Type thermocouple 0-1024°C
RPM engine speed input

The CAN cable between a VBOX / Video VBOX Pro and a Mini Input Module can be connected to either the DATA1 or DATA2 socket as they share the same CAN connections.
Two CAN connections are provided to allow the Mini Input Module to be daisy chained with more VBOX input modules. The cable needs to be ordered separately.
The RACELOGIC Tyre Temperature Monitoring System has been specifically designed to measure the highly transient surface temperature of a tyre, providing invaluable information for chassis tuning and driver development.
Each sensor can measure up to 16 temperature points on an object with surface temperatures ranging from -20° C to 300° C.
Why monitor tyre temperature?
Tyre performance is critical when you consider that the only contact the car has with the ground is a few square centimetres of rubber. The difference between a good and bad tyre setup can be the difference between a podium place and finishing last – or indeed not finishing at all. The whole car configuration distills down to those four small contact areas.
Tyre temperature is the most crucial part of the equation as racing rubber is designed to give the highest grip over a certain temperature range. Therefore, to get the best performance, you have to keep them within this operating window.
The traditional way to monitor this is to take a reading from each tyre as the car comes into the pits. But temperature measured like this is an average of the entire session and whilst it gives a rough idea, it is not ideal and certainly does not show the whole picture.
The only other feedback available comes from the driver, who will impart information based on their seat-of-the-pants impression of the car’s performance whilst at the wheel; only some drivers are good at this but it is always subjective.
Recognising the problem, Racelogic have introduced a new feature to their VBOX Video HD2 system that gets past the difficulties of tyre setup and allows for precise measurement of temperatures, whilst the car is moving.
VBOX infrared sensors, mounted in the proximity of each wheel, measure the temperature across the width of each tyre and the information is then recorded and overlaid in real-time on the video as a heat map. Consequently it is now possible for HD2 users to understand exactly what is happening to their rubber, at all points of the circuit. As this information is available on the video, it is extremely easy to interpret and see precisely what is happening.
Until you have seen the data, it is difficult to appreciate how much information you can gain from watching what happens to the surface of the tyre as the various loads change during braking, cornering and acceleration.
Take brake bias for instance, this is traditionally adjusted by driver feel and takes a fair amount of experience and car sensitivity. With the fast reacting temperature maps overlaid on the video, you can instantly see which tyres heat up first during the braking phase, and tweak the front to rear balance to even them out.
As a driver, it is often difficult to work out if you have locked the tyres up, but by watching the heat maps on the video you can spot when it happens, and on which tyre. This gives really useful data for setting up the suspension as well as the brakes.
As an example, Team Racelogic were testing their Fun Cup race car at a chilly Oulton Park earlier this year, with a track temperature of only a few degrees Centigrade. They were still struggling for front end grip, despite the fact that hand held measurements indicated that the front tyres were reaching optimal operating temperature.
Watching the video proved it was very much the opposite: when the car was out on the circuit, the surface of the tyre was being cooled by cold track and at high speed by the air. As the car slowed down and came into the pits, the surface of the tyre quickly heated up due to the heat soak from the main body of the tyre and the hot brakes, so static readings didn’t show the problem. After adjusting the pressures by a significant amount, the video showed the tyres retaining their temperature out on the track, resulting in less under-steer and an instant lap time improvement of 0.3 seconds.
This kind of data is invaluable when you are setting up the brakes, tyres and suspension of your race car, especially when you can just watch a video to work out what is happening extremely quickly and make simple adjustments to improve the performance of the car.
