Digital Inputs
The DIG
IN connector contains the two digital inputs for the VBOX III. Digital input 1 is also referred to as the Brake trigger input. This input is connected to an
internal timer capture module that is able to record precisely an event time for use in brake distance calculation. This period of time is called the trigger event
time, and is logged as the value in milliseconds between the trigger event and the last GPS sample.
A hand-held brake trigger is also available to allow the user to record marker events in the VBOX III data file.
A remote logging on/off switch is also available for ease of use and when the front panel switch is not accessible.
