Terminal Function
RUN Turns ON during RUN mode.
BUSY Shows that the V530-R150 is reading an image, changing settings, etc.
Do not input the next command while the BUSY signal is ON.
Otherwise, the commands input during command execution or processing may
not be properly executed.
OK/NG Outputs the judgment under the set reading conditions.
(Can be set to turn ON for either OK or NG judgment.)
GATE Used to control the timing with which the reading judgment is read at the external
device.
The duration for which the GATE terminal is turned ON can be set as required for
the external device to correctly read the reading judgment.
Make the output cycle longer than the gate ON delay plus the gate ON time, but
shorter than the duration of the reading (TRIG A input).
If the cycle is longer than the TRIG A input time, the output timing falls behind as
readings are repeated.
Gate ON delay, Gate ON time and Output period are set under the set communi-
cations conditions.

Terminal Function
TRIG A Inputs a reading trigger from a photoelectric sensor or other external device.
One reading is taken on the rising edge of the TRIG A signal.
Turn ON for at least 0.5ms. The duration of TRIG A signal input depends on read-
ing time. While reading is being performed, BUSY terminal turns ON and does
not accept input signals. Refer to 3-4 System Examination for the standard read-
ing time.
