VBOX Setup A/D 500 Hz
Digital Inputs
The ‘D IN’ connector contains the two digital inputs for the VBOX 3i. Digital input 1 is also referred to as the brake trigger
input. This input is connected to an event capture input on the GPS engine. This captures precisely the trigger event
time (10 ns resolution) for use in brake distance calculation. The trigger event time is logged and used to correct the
measured brake stop distance to the exact point at which the trigger was pressed.
A hand-held event marker is also available to allow the user to record marker events in the VBOX 3i data file.
A remote logging on/off switch is also available for ease of use and when the front panel switch is not accessible.
