Trigger Mode
Parameter # 138 (SSI # 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 DS457 detects an object in its field of view, it triggers and attempts 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.
•
Host - A host command issues the triggering signal. The DS457 interprets a trigger pull as a level
triggering option.
