Denso GT20Q-SB User Manual page 32

Note: Control commands cannot be used when HID (Human Interface Device Profile) is selected.
Note: Registered master data will be cleared in the following instance.
・ If parameter settings are changed using the configuration software (ScannerSetting_2D), batch setting QR
Code, or QR-coded parameter menu.
Note: Master data can be registered an unlimited number of times while the magic key is pressed and the indicator LED
is illuminated in green. The last code to be scanned is the master data.
Note: If master data registration using "preset master registration" or "master scanning registration" fails, the
indicator LED will flash in red. Code scanning is not available while the light is flashing.

2-Point Verification
Master Registration
1) Switch the scanner to the data verification mode. The indicator LED illuminates in green.
2) Scan and register the code to be used as master data. (Scan the code with the procedure for the trigger switch operation
mode selected.) The indicator LED will briefly illuminate in blue after master data is registered, and then go out.
3) Scan a code to verify. The scanner outputs the verification result after verifying the scanned data against the registered
master data.
When the scanner has scanned a code successfully, the indicator LED illuminates in blue before changing to green
indicating that it is in standby state awaiting new master data registration.
When registering the master data, an error occurs if the data read does not meet the number of characters of the registered
verification data, such as when the number of digits is less than the specified verification starting position. If an error occurs,
the scanner will return to the master data registration standby state.
* "Reverification attempt after NG judgment" in 2-point verification
2-point verification is provided with a "Reverification attempt after NG judgment" function to attempt reverification against
the same master data if the result of the data verification is a mismatch (NG judgment). If the reverification attempt function is
enabled using the configuration software (ScannerSetting_2D), the scanner will remain in code scanning standby state until
verification succeeds. When this function is disabled (default), the scanner will return to the master data registration standby
state after a single scan, regardless of the verification result.
Note: Registered master data will be cleared in the following instance.
- When the scanner is turned off
- When the verification starting position or verification digit numbers change
- If parameter settings are changed using the configuration software (ScannerSetting_2D), batch setting QR Code
or QR-coded parameter menu
Note: When an NG judgment is received after data verification, the user can select whether to implement the verification
process once more via the configuration software (ScannerSetting_2D).
Note: The verification range can be set to either "code type + code data" or "code data only" in the configuration
software (ScannerSetting_2D).
