My decoder outputs 11 digits of my UPC label. Can the decoder be set to output either ten or twelve digits?
Yes. A UPC bar code consists of the first digit (NSD or Number System Digit), the last digit (Check Digit) and the “inner 10” which are the core digits of the bar coded information. The decoder can be programmed to output the first and/or last digits to the host along with the core digits (by default, neither are output). For example, to get only the last 11 digits of the bar code, you would enable the “send check digit” function, while leaving “send system digit” disabled.
