5-50 QX-830 Compact Industrial Scanner User’s Manual
Read Cycle
Trailing Edge
Used to ignore accidental triggers when
Trigger Mode
is set to
External Edge
or
External Level
.
To consider a change in state on the trigger input, the level must be stable for the trigger
filter duration. In an edge mode, the scanner will trigger a read cycle if the active state has
been uninterrupted for the entire trigger filter duration. In a level mode, the trailing edge is
filtered such that on the falling edge, the state must be held for the trigger filter duration
before the trigger will be deemed inactive.
External Trigger State
Allows users to select the trigger polarity that will be used in their application.
Determines the active state of the trigger signal applied to the cable input of the scanner.
