Trigger Modes
Parameter # 8Ah
•
Level - A trigger event activates decode processing, which continues until the trigger event ends, a valid
decode, or the decode session time-out occurs.
•
Presentation Mode - When the Symbol SE4500 detects an object in its field of view, it triggers and attempt
to decode. The range of object detection does not vary under normal lighting conditions. This applies to
decode mode only. In this mode the unit does not enter Low Power mode.
•
Auto Aim - This trigger mode turns on the red laser aiming pattern when the Symbol SE4500 senses motion.
A trigger pull activates decode processing. After 2 seconds of inactivity the red laser aiming pattern
automatically shuts off.
•
Auto Aim with Illumination - This trigger mode turns on the red laser aiming pattern and internal
illumination LEDs when the Symbol SE4500 senses motion. A trigger pull activates decode processing. After
2 seconds of inactivity the red laser aiming pattern and internal illumination LEDs automatically shut off.
•
Host - A host command issues the triggering signal. The SE4500 interprets a trigger pull as a level triggering
option.
