Screen Blanking

The VX3Plus can be configured to blank the display when the vehicle to which it is mounted is moving, eliminating a possible
distraction for the driver. When configured properly, the screen blanking feature provides a tamper resistant method to blank
the vehicle screen. The screen blanking feature consists of Scanner Control Panel Options and a customer supplied cable
connected to one of the COM ports on the VX3Plus. Properly configured, the display is visible only when the cable provides a
signal that the vehicle has stopped.
The customer must supply their own cable. The cable specifications are detailed in

panel.
Screen blanking is configured on the Main tab of the Scanner control panel.
