programming page.
Programming Tip: If a symbology won't be used, we recommend turning it off
to minimize the chance of a misread.
Code 39 is a discrete, twoĆwidth symbology capable of encoding variable
length messages from the set of alphanumerics, and the $/+%.- and space.
The * character is used as the start and the stop character. Each Code 39
character has five bars and four internal spaces: three of these nine elements
are wide, the other six are narrow. It is this structure that gives Code 39 its name.
Default = On.
The start and stop characters are used to identify the leading and trailing ends
of the bar code. Since they are not considered part of the message they are not
ordinarily transmitted, though the reader can be programmed to transmit them.
Default = Don't Transmit.
The Code 39 specification provides a means of encoding the full ASCII set of
characters by using twoĆcharacter sequences made up of one of the four Code
39 characters ( $ + % / ) followed by one of the 26 letters as shown in the Full
ASCII Code 39 chart (on page 5-11). The decoder can't distinguish Code 39
labels encoded in full ASCII mode from those encoded in standard mode. Set
this decoder option according to the mode used when the symbols were
printed. Default = Enable.
When the append option is enabled, the reader will identify Code 39 messages
whose leading character is a SPACE, as Append39 symbols. The leading
SPACE is discarded and the remaining message characters are stored in a
buffer. When a nonĆ Append39 symbol is scanned, all data is transmitted in the
order it was scanned. Default = Disable.
