Programming the Scanner
3-30
Advanced Operation Control
This section allows the user to program the following
parameters for advance operation control. The definitions of
each parameter are described below.
Reread Delay
This feature is designed to inhibit the scanner from reading the same bar code
within a certain period of time. The time period can be programmed for
immediate, short, medium, or long time out duration. Another selection, Force
Verification, does not allow reading of the same bar code twice even after a
very long duration. Also note that this feature is not available if you have
selected Low Power Mode, Manual Trigger Mode, Level Mode, or Diagnostic
Mode.
Scan Voting
Scan Voting is the number of times the same bar code is decoded before it is
transmitted. This feature is useful when the bar codes being read are of poor
quality. It should also be noted that this feature is not available if you have
selected Low Power Mode, Manual Trigger Mode, Level Mode, or Diagnostic
Mode.
Auto Power Off Duration
The Auto Power Off Duration is a pre-defined power off time out counter for
Level Mode and Alternative Mode. You can adjust this parameter to meet your
own application requirement.
Pulse Driven Duty
The Pulse Driven Duty is designed to control the flashing frequency of the
light source. For example, the 1/2 duty cycle means that the scanner turns on
the light source at a time equal to 1/2 the duty cycle. Generally speaking, the
higher scan rate will take the higher duty.
