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.
How to set the number of retries.
→
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
Detail
Continuous mode (Default
setting)
Performs continuous reading while the TRIG B terminal is
ON.
In this mode, the reading accuracy and number of retry
settings are disabled for the TRIG B input.
Level trigger mode
Repeats reading while the TRIG B terminal is ON until
reading judgement is OK (readable).
3-2-2
Output Format
Signals are output in RUN mode but not in MON (monitor) mode.
OK/NG Terminal
Output OK/NG judgment.
Judgment
Detail
OK
OK when 2-dimensional codes are read successfully.
The reading data will be output to RS-232C.
NG
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.
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
