You can use the Digital Input to program the position of virtual lines in VBOX Omega, to set Start/Finish and Split lines. You must first make sure 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 should be connected to the Ground pin (pin 14) on VBOX Omega. This means that when the switch is pressed, the Digital Input pin will be shorted to ground. You can also use the Digital Input for an Event Marker.
