About the Screen Blanking Box
The screen blanking box helps improve operator safety and reduce driver
distractions by turning off the computer display when the vehicle is in
motion.
The screen blanking box monitors the connection of a vehicle motion-sensing
circuit. When motion is detected, the blanking box opens the connection, which
turns off the computer display. When motion is no longer detected, the
blanking box connects the output feeds and the display turns on again.
Caution: The screen blanking box should only be installed by trained service personnel.
Before You Begin
Before you install the screen blanking box, you need to supply power to the
vehicle mount computer. For information about the power supplies supported by
your computer, see the computer user manual.

(not included):
- Custom serial cable
- Mounting hardware and tools
- Grounding wire
- Input power cable with 3 Amp maximum time delay (slow blow) high-interrupting rated fuse
How to Create a Custom Serial Cable
You need to create a DB9 connector serial cable to connect from the screen blanking box to the vehicle mount computer.
