Code 39

Product Reference Guide 149

Code 39 — continued

Format

Use this feature to select standard or Full ASCII Code 39, which is an

enhanced set of Code 39 and uses a total of 128 characters to represent Full

ASCII code. Each Full ASCII Code 39 character is a combination of one of the

characters +,%, $ and / with an uppercase alphabetical character (A to Z).

Append

This function allows several symbols to be concatenated and be treated as a sin-

gle entry. The imager will not transmit the embedded appending code (for

Code-39, a space). If the append function is enabled and other symbols are

read again with the appended code, then the codes are transmitted without the

code ID, preamble, or prefix. When a symbol was decoded without the

appended code, the data is transmitted without the code ID and prefix, but the

postamble suffix codes are appended. This function is used when the first char-

acter of Code 39 data is a space.

Start/End Transmission

The start and end characters of Code 39 are asterisks (*). You can transmit all

data digits, including the two asterisks.
