Start Character (Non-Delimited)
Useful in applications where different characters are required to start a read cycle.
A single ASCII host serial trigger character that starts the read cycle and is not enclosed
by delimiters such as <
Non-delimited Start characters can be defined and will function according to the trigger event.
When defining Start trigger characters, the following rules apply:
In External Edge the imager looks only for the Start trigger character and ignores any
Stop trigger character that may be defined.
In External Level the Start trigger character begins the read cycle and the Stop trigger
character ends it. Note that even after a symbol has been decoded and the symbol data
transmitted, the imager remains in External Level trigger read cycle until a Stop character
is received.
In Serial Data and Edge
trigger can start an edge trigger read cycle.
