Multiple label read collectively output
Barcode reading starts when the reading request is turned on. Reading continues while the request is on, and when the
reading request is turned off, the reading operation stops and the reading results are collectively output.
The maximum number of barcodes that can be collectively output is 16. Readout data after the 17th barcode is discarded.
This becomes "edge-triggered" if the reading timeout time is set between 100 ms and 25,500 ms and "level-triggered" if
set to infinity.
If the reading request is turned on with the external trigger input and level-triggered, the stop condition is the following.
z
External trigger input off
To control the reading request with control commands, refer to
F
P. 3-10 "Start conditions and stop conditions for
reading requests" .
The following timing chart is an example of operation by the external trigger input and level-triggered.

z
The total number of characters for reading results [1] to [n] must be 512 characters or less.
If the total number of characters exceeds 512 characters, the content of the output results is not guaranteed.
z
The prevention time of same read is set between 100 ms and 25,500 ms.
z
Barcodes with the same content cannot be continuously read during the prevention time of same read. If
barcodes have different content, they can be read.
z
The OK output, NG output, PWM output, and indicator LEDs (green/red) only reflect the final reading results.
z
The operation of the OK output, NG output, PWM output, and indicator LEDs varies depending on the set-
tings.
z
The indicator LED (orange) turns on when barcode reading starts if the reading linked control setting is en-
abled. It turns off when the set illumination time elapses or when barcode reading stops.
z
The indicator LEDs (green/red) turn on when barcode reading stops if the reading linked control setting is
enabled. They turn off when the set illumination time elapses or when barcode reading starts.
z
If the reading linked control setting is enabled, reading success/failure or matched/not matched is judged
when barcode reading stops, and the OK output, NG output, and PWM output are controlled according to
the settings.
