Hi, we've got a client that needs to encode a large alphanumeric value which results in a large barcode. The resulting code is too large for the scanner to read.
Could we break it apart in, say, two rows; so we first scan the first row, read the second row and then have the data?
e.g. what I'm trying to ask is break this:
|| ||| ||| ||||| |||
Would this work with a simple scanner? I don't think it has a trigger and we would need to scan the first pass, scan second pass and then have the "beep".
The series of AI + data that you mention would require a
SC + FNC1 + AI + Data + CH + EC for each part?
where SC = start code, CH = checksum, EC = end code.
Or could it read a
SC + FNC1 + AI + Data (1st pass)
FNC1 + AI + Data (2nd pass)
FNC1 + AI + Data CH + EC) (say a 3rd pass)?
The above is what we would like to have. I don't think we have access to the scanners driver to check ourselves what we read.

You will need a scanner capable of "input buffering" in your case. A better solution is to change the behavior at the application side to buffer the scanner input.
