3.7 Additional Information
When sending the bar code data, you can add the following data to the readout
data.
Additional information types
■ Decode match count add function
Adds the number of successful scans during one bar code reading (decode count)
to the end of the readout data (up to 9999 count). However, this decode count is
never less than the preset decoding match count.
This function can be used to check reading stability and code label quality.
* The value is zero-suppressed.
When using this function, output turns on at a different time from normal operation.
• In single label read mode, output turns on after one bar code has been read
(after trigger input turns off). Even if you set the data send to “after read”, the
data is forced sent after trigger input turns off.
• In multi-label read mode 1, a bar code passes across the laser beam’s field,
after repeat read time, and is finally output.
• In multi-label read mode 2 or 3, operation is the same as when you do not use
the decode match count adding function.
■ Scan count add function (valid only when using the read count add func-
tion)
Adds the number of scans, including when no bar code exists, to the end of the
decode count (up to 9999).
* The value is zero-suppressed.
