Trigger
Continuous Read 1 Output
Continuous Read 1 Output can be useful in applications where it is not feasible
Usage:
to use a trigger and all succeeding symbols contain different information. It is
also effective in applications where the objects are hand-presented.
Definition: In Continuous Read 1 Output the scanner self-triggers whenever it decodes
a new symbol or a timeout occurs.
If End Of Read Cycle is set to Timeout and the symbol doesn't change, the
scanner will repeat the output at the end of each timeout period. For example,
if Timeout is set to one second, the scanner sends the symbol data immediately
and repeats the output at intervals of one second for as long as the symbol
continues to be scanned.
If End Of Read Cycle is set to New Trigger, the scanner will send the current
symbol data immediately, but send it only once. A new symbol appearing in
the scanner's range will be read and sent immediately provided it is not
identical to the previous symbol read.
Serial Cmd: <K200,1>
Caution: In automated environments, Continuous Read 1 Output is not
recommended because there is no one to verify that a symbol was missed.
Note: If Trigger is set to Continuous Read 1 Output, Number of Symbols
will default back to 1 (if set to any number greater than 1).
