6.6 Additional Information Function
This section describes the additional information function that allows the BL-600
Series to send the read data together with various additional data.
6.6.1 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.
■ Data format
* The partition mark (:) can be changed as desired (1 character max.).
■ Data output timing
If the decoding count add function is used, the data is output at a different time
than with normal operation.
• If single label read mode is used:
The data is always output after the trigger input turns off.
• If multi-label read mode 1 is used:
The data is output when the repeat-reading time has passed after a bar code
passes across the field of the laser beam.
• If multi-label read mode 2 or 3 is used:
The operation is the same as when the decoding count add function is not
used.
6.6.2 Scan count add function (valid only if using the decoding count add
function)
If the decoding count add function is used, you can add the number of scans while
the trigger input is on, including when the reading has failed and when a bar code
does not exist, to the end of the decoding count (up to 9999).
■ Data format
* The partition mark (:) can be changed as desired (1 character max.).
However, the partition mark for the scan count (/) cannot be changed.
