Not sure but I do note there is 16 bits of information in that code.
So 2^16 = 65,536 possibilities

Are you trying to work out what J-021 is?

Do you know if the barcode represents J- also?
Or does it just represent 021 and the reader knows that the format is to have a J- in front?

What is the total range of the barcode? Letters, numbers, J-* or *-*** or something else?

Looks too difficult to me

edit: Okay so the top three marks are different and so I dont think that the barcode has the J- represented in it, unless there is some sort of decoding done at the end.

raytaylor:

Yes I'm trying to work out how to generate J-nnn myself.

Do you know if the barcode represents J- also?
Or does it just represent 021 and the reader knows that the format is to have a J- in front?


The application that utilises the barcode on displays the number e.g. 9, 10, 11 etc so "J-" maybe irrelevant. 

What is the total range of the barcode? Letters, numbers, J-* or *-*** or something else?


The have a range of barcodes up to 240 however would like to test if my application would recognise any barcodes generated up to 999.

This is the circuit used to read the barcode, hopefully someone can make use of it:

Did you get any further with this?  Its intriguing but I couldn't see a logical sequence.  Have you got any further background details on what the codes do or what they signify?  The chip appears to be a 8 bit shift register, but what does it feed the scanned values to?  Is there a processor with on-chip ROM code, or something running embedded software to process the barcode values?

It could possibly have these bit values, given a zero-based sequence, black=0 white=1

?? ?? ?? ?? ?? 02 04 08
16 ?? ?? ?? ?? ?? ?? ??

But the other bits are uncertain, it may not a numeric series.

I'm starting to see a pattern. Yep I should be asleep instead of trying to figure out how the barcodes are generated. Will hopefully post back tomorrow.
