er Manual 5-13
Read Cycle
Start Trigger Character (Non-Delimited)
Important:
The ASCII characters
<
,
>
, and
,
can only be entered as hex pairs:
For <: <K229h,3C>
For >: <K229h,3E>
For
, : <K229h,2C>
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 imager looks only for the Start trigger characte
r
a
nd ignores any Stop trigger character that may be defined.
•In External Level the Start trigger character begins the read cycle an
d
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 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
.
