1D Symbologies
Large Intercharacter Gap (Codabar)
Usage: It is helpful for reading symbols that are printed out of specification.
Caution: Do not use Large Intercharacter Gap with Narrow Margins
enabled since enabling Large Intercharacter Gap (over 3x) could
cause a narrow margins (5x) to be interpreted as an intercharacter gap.
Definition: Instructs the scanner to read symbols with gaps between characters
exceeding three times the narrow element width.
Serial Cmd: <Kqstatus,start & stop match,start & stop output

Default: Disabled
Options: 0 = Disabled
Fixed Symbol Length Status (Codabar)
Usage: Fixed Symbol Length helps prevent truncations and increases data
integrity by ensuring that only one symbol length will be accepted.
Definition:
When enabled, the scanner will check the symbol length against the fixed
symbol length field. When disabled, any length would be considered a
valid symbol.

Symbol Length (Codabar)
Definition: Specifies the exact number of characters that the scanner will recognize
(this does not include start and stop and check digit characters). The
scanner ignores any symbol not having the specified length.
Serial Cmd: <Kqstatus,start & stop match,start & stop match output,large interchar-
acter gap,fixed symbol length
type,check digit output>
Default: 10
Options: 1 to 64
Note: Fixed Symbol Length Status must be enabled for Fixed Symbol Length to take effect.
Note: Because of symbology limitations, setting Symbol Length to any number less
than four will produce undetermined results.
