SCANTEAM 3700 Wedge Technical Manual
Full ASCII
Append
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 6-9). The 3700 Wedge 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.
Programming Tip: If a symbology won't be used, we recommend turning it off
to minimize the chance of a misread.

Decoding
The 3700 Wedge uses industry standard decoding algorithms to ensure data
integrity. Adaptive decoding employs a more aggressive decoding algorithm
that is more tolerant when bar code symbols do not conform to the symbology
specifications and that results in snappier" scanning. Default = Adaptive.
