V440-F C-Mount Code Reader User Manual
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 < 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.
<K229,start character>
NUL (00 in hex) (disabled)
