Beam Shutter Settings
Beam Shutter
Select Disabled, Enabled, or Triggered from the drop-down list. The Beam Shutter
turns the laser off and can be used to increase the overall laser diode life when
used in high ambient temperature applications (over 35° C); to reduce power
consumption; or to turn off the laser for safety purposes.
•Disabled: The laser is always on.
•Triggered: The laser is turned off as soon as the code(s) are read or when the
reading phase ends. The laser is turned on again when the next reading phase
starts
•Enabled: The laser is always off and all operations are suspended.
PackTrack Beam Shutter Timeout
Select a time value from the drop-down list. This parameter is available only when
Operating Mode = PackTrack™ and Beam Shutter
= Triggered. By setting this
parameter the laser is turned off as soon as the selected timeout expires. The next
trigger signal will turn the laser back on.
