Screen Blanking Box
Caution
Please refer to the label on the screen blanking box for allowable input voltage range.
The Screen Blanking Box is designed to monitor a connection to a vehicle motion sensing circuit. When motion is detected, the
Screen Blanking Box opens the connection between the output feeds (which are connected to Pins 7 and 8 of the Thor VM1)
and the display on the Thor VM1 is blanked. When motion is no longer detected the Screen Blanking Box provides a connection
between the output feeds. After the configured Screen On delay, if any, the Thor VM1 screen is displayed.
Please refer to the wiring instructions, including appropriate cautions and warnings, in the Thor VM1 User Guide .
Screen Blanking with Switch
In applications where it is impractical to use the screen blanking box due to vehicle voltage or lack of a motion sensing signal,
screen blanking can be controlled via a user supplied switch or relay that provides an electrical conductive connection between
the wires connected to Pins 7 and 8 of the screen blanking cable on vehicle motion.
