Screen Blanking
The TaskBook has the ability to blank the screen when positive
voltage is applied to a designated COM port pin. This is typically used
to blank the screen when a vehicle is in motion, a requirement is
some countries. For the TaskBook, an external sensor must be used
that will either provide a positive voltage when the vehicle moves, or
closes a relay in the same circumstance. If using a relay, then the
positive voltage from pin 9 of the selected COM port should be wired
as input to the relay. The output from the sensor or relay should be
wired to pin 1 (DCD) or pin 6 (DSR) of the selected COM port. The
screen blanking cable from Datalogic (p/n 94ACC0157) is wired to pin
9 (pink) and pin 6 (grey).
Configuration
Locate (or add) the line ScreenBlankBits=X in the [General] section of
the file. X should be set to the appropriate value from the list:
• 1 – COM1: DCD (pin 1)
• 2 – COM1: DSR (pin 6)
• 4 – COM2: DCD (pin 1)
• 8 – COM2: DSR (pin 6)
Deleting the ScreenBlankBits line from the cfg file will turn off screen
blanking.
NOTE
This applies only when TaskBook is used on a docking
station installed on a forklift and the screen blanking cable
is connected to the motion sensor of the vehicle.
