For

See ASCII Character Entry Modifier on page 3-32 for a detailed explanation of how to
enter ASCII characters as hex values.
Usage:
Useful in applications where different characters are required to end a
read cycle.
Definition:
A single ASCII host serial trigger character that ends the read cycle and is
not enclosed by delimiters such as
< and > .
Non-delimited Stop characters can be defined and will function according
to the trigger event.
When defining Stop 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.
Serial Cmd:
< K230,stop character >
Default:
NUL (00 in hex) (disabled)
Options:
Two hex digits representing an ASCII character.
