MS-3000 Single Head Decoder User's Manual
"End of Read Cycle" on page
Has this effect:
Trigger input options are disabled and the decoder is
always in the read cycle. Bar code data is decoded,
and label information is transmitted repeatedly, as
long as the label is in the range of the scan head.
When To Output options have no affect on
Continuous Read. Continuous Read is useful in
testing label or scan head functions.
Label data is immediately transmitted with Timeout
enabled for End Of Read Cycle. If the label doesn't
change, the decoder will repeat the output at the end
of each subsequent timeout period. For example, if
Timeout were set to one second, the decoder would
output the label data immediately, and then repeat
the output at intervals of one second, for as long as
the label continued to be scanned.
With Timeout disabled (that is, End Of Read Cycle
set to New Trigger), the decoder will output the
current label data immediately, but output it only
once. A new label appearing at any time in the scan
range will produce a new read output as long as the
new label is not identical to the previous label.
Allows a read cycle to be initiated by a trigger signal
from an object detector when an object appears
within the detector's range. The read cycle endures
until the object moves out of the detector's range
(figure -1 on page -15), unless a timeout occurs
and Timeout is enabled for End of Read Cycle
