7.6.2.2 Other Options
Verify
The value entered for this parameter determines the number of correct additional
decodes required after the initial decode before a bar code is accepted. The
allowable range is 0 to 15. Higher values significantly increase the time it takes to
decode a bar code.
Security
This parameter controls the tolerance for decoding edge-to-edge bar codes
(Code 93, Code 128, UPC/EAN). The allowable value is 0 to 99. Lower values have
a lower tolerance for misreads, but they also increase the time it takes to decode the
bar code.
Short Code
When enabled (set to “Y”), this parameter allows scanning of short I 2 of 5 bar
codes (2 characters). When “Short Code” is disabled (set to “N”), these short bar
codes are rejected.
Setting this parameter to “Y” may reduce the robustness of the decoding since the
terminal must decode more potential bar codes. For this reason, it is not
recommended that “Short Code” be enabled for general-purpose bar codes with 4 or
more characters.
Click Time
Note: This parameter only effects terminals using long-range scanners.
This parameter controls the maximum gap time (in milliseconds) for a double-click.
If the time between the first and second clicks of the scanner trigger is within this
time, it is considered a double-click. The allowable range is 0 to 1000. A value of
zero disables this feature.
A double-click produces different results depending on whether or not a value is
assigned in the “Click Data” parameter (see page 134). When a value is not assigned
for the “Click Data”, double-clicking the scanner trigger overrides the target dot
delay set in the “Dot Time” parameter and initiates a normal scan sweep. If a value
is assigned for the “Click Data” parameter, double-clicking the scanner trigger
inserts the “Click Data” value rather than initiating a scan.
