07 - VB3iS Digital Input

The Digital Input can be used to program the position of virtual lines in VB3iS, allowing for the setting of Start/Finish and Split lines. You must first ensure that you have a connection to the Digital Input (pin 13). This pin should be connected to one side of a momentary switch and the other side of the switch connected to the Ground pin (pin 14) of VB3iS, so that when the switch is pressed, the Digital Input pin will be shorted to Ground. The Digital Input can also be used for a Brake Trigger.

Track Marker Mode

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.

After you have set a start/finish, finish or split line(s), you can view the latitude and longitude of this line position within the 'Virtual gates' section of the ‘Tests’ menu within VBOX Setup Software. If the software is already connected, 'Disconnect' and then ‘Connect’ again to refresh the settings.

Set a Start/Finish Line

Press and immediately release the Lap input switch as you cross the start/finish line. You must be moving >5 km/h to do this and following the normal line along the track. VB3iS notes the point and direction of travel, then creates a virtual line perpendicular to your line of travel 25 m wide. 

Set a Separate Finish Line

Press hold the switch for >5 seconds before releasing as you cross the finish line. You must be moving >5 km/h to do this and following the normal line along the track. VB3iS notes the point and direction of travel, then creates a virtual line perpendicular to your line of travel 25 m wide.

Set a Split Line

Double press the input switch twice within a very short period. You must be moving >5 km/h to do this and following the normal line along the track. VB3iS notes the point and direction of travel, then creates a virtual line perpendicular to your line of travel 25 m wide.

Clear All Virtual Lines

Give the input switch a short press followed by a longer button press (>1.5 seconds). In each case, VB3iS will recognise the lead edge of the first pulse as the activation in order to set the associated virtual line at the exact point that the user first presses the switch.

Coldstart

This can be performed by grounding the input at the same time as connecting VB3iS to power.

Brake Trigger Mode

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. 

Configuration

The digital input can be configured as either Track Marker or Brake Trigger mode via the VBOX Setup Softwarethe Front Panel of the unit or using the VBOX Manager.

VBOX Setup Software

  1. Ensure VB3iS is powered.
  2. Connect VB3iS to a computer using the supplied loom, connect an RLCAB001 cable to the 'CONFIG' lead and connect the serial plug to the computers serial port – this can be done via a serial > USB convertor if required.
  3. Open VBOX Setup and connect to VB3iS by selecting the correct COM Port.
 
  1. Select the 'Digital I/O' menu and then choose the desired setting from the 'Digital input' options.
