Setup Menu
The Scanner Setup menu allows you to set specific bar code scanning parameters that
affect decode rate.
DEFAULT
Clicking the
DEFAULT
button will reset all parameters on the current menu to
defaults. This does not take effect until it is saved to the scanner with the
SEND/NO
SAVE
or
SEND/SAVE
buttons.
Scan Speed
Default:
800
(scans per second).
Options:
350 to 1100.
Allows you to set the number of scans per second by controlling the spinning mirror
motor speed. The range is 350 to 1100 scans per second.
AGC Sampling
Default:
Continuous
Options:
Continuous, Disabled, Leading Edge
Allows you to specify how automatic gain control sampling will be done. Continuous
mode continually samples 14 transitions and stores the highest value of the samples
and adjusts the AGC value at the end of the scan. Leading Edge mode finds the lead-
ing edge by looking for a 40 µs quiet zone followed by 14 transitions and stores the
highest value of the samples and adjusts the AGC at the end of the scan. Leading
Edge is especially effective when labels are skewed. Changes to AGC Sampling should
typically be done by qualified technicians.
Transition Counter Parameters
Default:
Disabled
Options:
Disabled, Enabled
Allows you to define the minimum number of label space transitions (bars and spaces)
at which a label is detected.
Minimum Label Transitions
Default:
14
Options:
3 to 255
The number you enter is derived by testing several objects with labels while in the
Extended Decode Rate Test. Select a number that is one or two numbers less than the
smallest value displayed for number of label space transitions.
