G-6-4 Fixed Symbol Length Status (Code 39)
Definition: When enabled, the reader will check the symbol length against the symbol
length field. If disabled, any length will be considered valid.
Serial Cmd: <K470,status,check character status,check character output status,large
intercharacter gap,fixed symbol length status,fixed symbol length,full

Default: Disabled
Options: 0 = Disabled 1 = Enabled
G-6-5 Fixed Symbol Length (Code 39)
Usage: Fixed Symbol Length helps prevent truncations and increases data integrity
by ensuring that only one symbol length will be accepted.
Definition: Specifies the exact number of characters that the reader will recognize (this
does not include start and stop and check characters). The reader ignores
any symbology that does not match the specified length.
Serial Cmd: <K470,status,check character status,check character output status,large
intercharacter gap,fixed symbol length status,fixed symbol length,full
ASCII set>
Default: 10
Options: 1 to 64
G-6-6 Full ASCII Set (Code 39)
Usage: Must be enabled when reading characters outside the standard character
set (0-9, A-Z, etc.)
The user must know in advance whether or not to use the Full ASCII Set
option. Since Full ASCII Set requires two code words to encode one
character, it is less efficient.
Definition: Standard Code 39 encodes 43 characters; zero through nine, capital “A”
through capital “Z”, minus symbol, plus symbol, forward slash, space,
decimal point, dollar sign, and percent symbol. When Full ASCII Set is
enabled, the reader can read the full ASCII character set, from 0 to 255.
Serial Cmd: <K470,status,check character status,check character output status,large

set>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
