Reflect in Total Judgement
You can specify whether to reflect the verification result of a 2D code inspection item in the overall judgement.
(The default setting is [Yes].)

[Reflect]
Detail Settings
With the default settings, all of the parameters are set automatically. If the automatic settings are incorrect for
any reason, e.g., the code was read incorrect, set the detailed parameters manually and then perform teaching.
[Inspect] − [Inspection] − [Add item.] − [2D-code] − [Details] Tab Page
Press [Meas. Parameter]
Set the measurement parameters.
Be sure to always specify the code type. When you automatically register matrix data, the code type, code
color, data matrix shape, and reverse settings are set automatically.
Outputting Read Characters to an External Device
After a measurement, you can automatically output the character string that was read with the 2D-code
inspection item to a PLC or other external device. The character strings are output after outputting the output
data (output data settings 0 to 31), such as the inspection item parameters and calculation result.
Refer to the description for the communications format for the setting procedure and output specifications to
output the character string.
