Brake trigger

Enabling this mode allows the Digital Input to be used with a brake trigger. Activation of the trigger will start the brake stop distance measurement, where VB3iS will calculate a Time and Distance for a Brake Trigger to 0 km/h test. 

Track marker

Enabling this mode allows the Digital Input to be used as a lap pulse. The input switch can be used to set a start/ finish line, set a separate finish line, set a split line, clear all virtual lines and perform a coldstart.

  • Set a start/finish line - Press and release of the input switch. GNSS speed must be greater than 5 km/h and the virtual line will be perpendicular to the direction of travel.
  • Set a separate finish line - Press and hold of the input switch for more than 5 seconds. GNSS speed must be greater than 5 km/h and the virtual line will be perpendicular to the direction of travel.
  • Set a split line - Double press of the input switch. GNSS speed must be greater than 5 km/h and the virtual line will be perpendicular to the direction of travel.
  • Clear all virtual lines - Short press followed by a longer press over 1.5 seconds.
  • Perform a coldstart - Grounding the Digital input whilst connecting to power.
 
  1. Digital output

Defines the digital output of VB3iS.

Speed

The speed output is configured by changing the number of pulses per metre (90 pulses/m = 25 Hz per km/h as default).

Lap pulse

When this option is enabled, VB3iS will output a 5 V pulse for 1 second (by default) when a Start/Finish line is crossed. The duration of the pulse in seconds can be adjusted by entering a different value.

The polarity of the pulse can be changed to either a rising or falling pulse by selecting the marker next to the desired image.
