Non-delimited Start and Stop Characters
Note: If the serial trigger character that you assign is already assigned as an opera-
tional command—for example a "Z" character that is used in the
command will no longer function as intended.
Both Start and Stop non-delimited characters can be defined and will function accord-
ing to the trigger event, as follows:
When defining Start and Stop 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 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 & Edge trigger mode, command, either a Start Trigger Character
or a hardware trigger can start an Edge trigger read cycle.
Start Character (non-delimited)
Usage: Useful in applications where different characters are required to start and
end a read cycle.
Definition: A single ASCII host serial trigger character that starts the read cycle and
is not enclosed by delimiters such as
Serial Cmd: <K229,start trigger
Default: Null (disabled)
Options: Two hex digits representing an ASCII character except <, >,
XOFF.
Stop Character (non-delimited)
Usage: Useful in applications where different characters are required to start and
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
Serial Cmd: <K230,stop trigger
Default: Null (disabled)
Options: Two hex digits representing an ASCII character except <, >,
XOFF.
