Edge-triggered
Edge-triggered executes barcode reading after detecting the rising edge in the reading request (off→on).
If the reading timeout time is set between 100 ms and 25,500 ms, single label read is edge-triggered. For details, refer to
"3. 5 Configuration item table" -
F
P. 3-39 "Barcode reading" .
When the reading request is turned on with the external trigger input, the stop condition is either of the following.
z
Reading succeeded
z
Reading timeout time elapsed
To control the reading request with the Operation button or 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.

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.
