External Input/Output (QB30-SR only)
11.1 External Trigger Terminal
The scanner can start and end scanning using the trigger signal input by the external trigger terminal.
11.2 External Reset Terminal
The scanner can reset using the reset signal input by the external reset terminal.
11.3 External Terminal
The scanner is capable of outputting the following 6 types of signals. Each signal can be assigned to an output terminal 1
or output terminal 2. (However, SHT signals can only be assigned to an output terminal 2.) Output signals can be set using
the commands or configuration software.
(1) OK signal
This signal is output by turning the OUTPUT Tr (transistor) ON at a specific timing to indicate the successful
completion of scanning. Note 1
(2) NG signal
This signal is output by turning the OUTPUT Tr (transistor) ON at a specific timing to indicate that scanning has been
unsuccessful. Note 1
(3) SHT signal (External light sync signal)
This signal is used for lighting ON/OFF control when using external lighting. , and can be used to turn ON the lighting
only for the scanner exposure time.
(4) Verification OK signal
When using the verification function, this signal is output by turning the OUTPUT Tr (transistor) ON at a specific
timing to indicate the successful completion of scanning. Note 1
(5) Verification NG signal
When using the verification function, this signal is output by turning the OUTPUT Tr (transistor) ON at a specific
timing to indicate that scanning has been unsuccessful. Note 1
(6) READY signal
This signal is output by turning the OUTPUT Tr (Transistor) ON at a specific timing to indicate that the scanner is in a
ready condition. The trigger signal or trigger command is ignored when the scanner is not in a ready mode. Ready
conditions refer to the following conditions.
・ When not in the scan timing (including data transmission) condition
・ When not in setting mode using commands
・ When not in the master data registration condition in the data verification mode
・ When not connecting with configuration software
The ready signal is constantly OFF when the following trigger modes are applied:
・ Continuous reading mode A
・ Continuous reading mode B
・ Luminosity setting of auto sense mode consists of shutter time and sensor gain (Referred to as Gain).
The selection of the OK, NG, SHT, Verification NG and READY signal output enabled/disabled status, ON duration
width, and delay time from output timing can be set using the commands or configuration software.
(Note 1) The signal is not output while the scan test is operated.
