Definition:
|
A single ASCII host serial trigger character
that starts the read cycle and is not enclosed by delimiters such
as < and >.
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 or
External Edge trigger mode, either a Start trigger character or a
hardware trigger can start an edge trigger read cycle.
