Title: Bar codes for parts less than 4 characters long
Post by gtladmin on 02/10/09 at 07:44:25

I've added bar coded fields to our packing slips and we noticed that some of our part numbers that are less than 4 characters do not scan at all. Walter did some testing and determined the fields have to be at least 4 characters for the field to scan, no matter what format (code 39, code 128, ascii, etc.). Why is that? We can get the fields to scan if we add a couple of spaces in a two character part # field, or 3 spaces in single character part field. But will that mess up Evo some how, some way, at some point by putting spaces in part # fields?

How do we get around this issue?

Also the spaces add a carriage return, which is good and also bad in some cases.

Thanks,

Val

So, it's probably OK to put spaces in a part #? I assume so since I have not heard from anyone on this issue.....

After doing some research, there is a minimum and maximum on bar codes for Code 39 (and 128, ASCII, etc.--we use Code 39). Anyway, it appears 4 is the minimum, so anything less than 4 characters will not scan. I did discover, however, it may be possible to "reprogram" our hand held scanners to accecpt less characters by changing a global parameter in the scanner. Just have to figure out how to do it with our scanners.

But I assume it's not a good idea to allow Walter to just add spaces into the part #s in Evo? Like changing a Part code W to W(space)(space)(space).

No do not just add spaces... that is a bad Idea. All the finds and lookups would most likely not work if you did it that way.

I was able to successfully reprogram the scanners to accept 1 character barcodes. We are all set. A simple solution. :)

I am having the same problem. Packing slips with bar-codes for our quantity is not allowing the customer to scan. All other fields were able to scan on their scanner. Our table shows "decimal" place of 2. Could this be the issue that it is reading the "decimal"? How to change the decimal in the table to remove? Anyone experience this before? Note - our packing slip numbers are 3 characters long and they are able to scan that.

Help? ;)
