Read Cycle
MS-860 Industrial Raster Reader User’s Manual

Continuous Read 1 Output
Caution: In automated environments, Continuous Read 1 Output is not recom-
mended 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).
Usage:
Continuous Read 1 Output can be useful in applications where it is not
feasible 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 reader 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 reader will repeat the output at the end of each timeout period. For
example, if
Timeout is set to one second, the reader 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 reader will send the
current symbol data immediately, but send it only once. A new symbol
appearing in the reader’s range will be read and sent immediately pro-
vided it is not identical to the previous symbol read.
