Description
TRIG B mode
(TRIG B)
Select continuous reading or reading until OK judgement output.
Continuous reading
(default setting)
Performs continuous reading while the TRIG B terminal is ON.
TRIG B input invalidates the

setting.
Level trigger
Repeats reading until an OK (readable) reading judgement is out-
put while the TRIG B terminal is ON.
In the case of an NG (not readable) reading, the NG signal is out-
put when the TRIG B is turned OFF.
TRIG C mode
(TRIG C)
Switches to the set scene number and reading is executed with the “level trigger” specifica-
tion. (Scene 0 to 9; default setting: Scene 0)
TRIG D mode
(TRIG D)
Switches to the set scene number and reading is executed with the “level trigger” specifica-
tion. (Scene 0 to 9; default setting: Scene 0)
ON state
Select whether the OK/NG signal is turned ON when the judgement result is OK or when it
is NG.
NG: ON
(default setting)
The OK/NG signal is turned ON for an NG reading.
OK: ON
The OK/NG signal is turned ON for an OK reading.
Output period Set the output period for reading judgement. Set a value between 2.0 and 10000.0 ms that
is greater than the “Gate ON delay + Gate ON time”, and less than the reading interval. If
the cycle is longer than the reading interval, the output timing will fall behind as the read-
ings are repeated.
(2.0 to 10000.0 ms; default setting: 10.0 ms)
Gate ON
delay
Set the time from parallel I/O result output to turning ON of the GATE signal. This time is
used to wait until the data output becomes stable. Set a time between 1.0 and 1000.0 ms
that is longer than the delay time for the host device.
(1.0 to 1000.0 ms; default setting: 1.0 ms)
Gate ON time Set the time during which the GATE signal is ON.
Set the time required for the host to input the reading result.
(1.0 to 1000.0 ms; default setting: 5.0 ms)
