F
F-6-1 Serial Trigger Character (Delimited)
F-7 Start Trigger Character (Non-
Delimited)
Usage: Useful in applications where different characters are required to start a
read cycle.
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 reader 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 reader 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.
Serial Cmd: <K229,start character>
Default: NUL (00 in hex) (disabled)
Options:
Two hex digits representing any ASCII character except
XON
and
XOFF
.
