Trigger Input and Output Format
3-2-1
Trigger Input
Reading is performed by inputting a signal to the TRIG A or B ter-
minals when in MON (monitor) or RUN mode.
TRIG A Terminal (One shot mode)
One reading is performed on the rising edge (OFF to ON) of
TRIG A signal.
Correct Reading: Reading ends, then reading judgment is out-
put.
Incorrect Reading: Reading continues to be performed for the
number of retries specified in the setting conditions.
As the TRIG A signal is synchronous with the shutter input of the
Camera, an accurate image of the moving object can be ob-
tained.
TRIG B Terminal (Continuous mode / Level trigger mode)
Changed by setting of communications specifications.
Trigger Mode
Continuous mode (Default
setting)
Level trigger mode

Output Format
Signals are output in RUN mode but not in MON (monitor) mode.
OK/NG Terminal
Output OK/NG judgment.
Judgment
OK
NG
OK: ON or NG: ON (i.e.: whether output turns ON for an OK judg-
ment or an NG judgment) can be selected in the communications
How to set the number of retries.

Performs continuous reading while the TRIG B terminal is
ON.
Repeats reading while the TRIG B terminal is ON until
reading judgement is OK (readable).
OK when 2-dimensional codes are read successfully.
The reading data will be output to RS-232C.
NG when 2-dimensional codes are not read successfully.
The error code will be output to RS-232C.
NG when coincidence judgment is set to ON and the
reading data is not coincident with the registered data 0 to
3.
The reading data will be output to RS-232C.
