VBOX 3iSDR
VBOX 3iSDR
The VBOX Pedal Force Event Marker Interface captures the precise moment that any pressure is applied to a brake pedal and outputs a digital signal, which can be used to trigger the start of a test.
It connects inline between the VBOX Brake Pedal Force Sensor (RLACS282) and Digital input port on a VBOX 3i. The interface acts in a similar way to a traditional brake pedal trigger, but with the added benefit of also allowing the measurement of pedal force.
The internal circuitry of the interface constantly monitors the pedal force sensor voltage and adjusts the trigger threshold. This accounts for any fluctuations in pedal force caused by changes in temperature of the sensor itself, preventing incorrect trigger activation.
