Display Backlight Control - Honeywell Thor VM2 User Manual

Screen Blanking
Screen blanking (blackout) can be enabled when the vehicle is in motion. See Screen Blanking (page 4-35) for hardware
setup and Screen Control (page 5-44) for software setup to enable screen blanking. Once screen blanking is enabled, the
display is blanked out any time when the cable sends the signal that the vehicle is in motion. If the cable is removed, screen
blanking is disabled and the display remains on.
