Read Cycle

Stop Trigger Character (Non-Delimited)

Important: The ASCII characters <, >, and , can only be entered as hex

pairs:

For <: <K230h,3C>

For >: <K230h,3E>

For , : <K230h,2C>

See ASCII Character Entry Modifier on page 4-33 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 characte

nd ignores any Stop trigger character that may be defined.

•In External Level the Start trigger character begins the read cycle an

the St

op 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 and Edge trigger mode, either a Start trigger characte

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.
