Code Filter

Mode Setting
Select Disable, Timeout, Encoder Steps, or Tx Line from the On
Line Options drop-down list. This parameter determines criteria for
flushing entries from the code filtering list depending on the type of
list management:

The Code Filter Depth parameter, when not = 0, manages
a FIFO (First In First Out) list of codes which are compared
for filtering. The Timeout and Encoder Steps values are in
addition to the cyclical flushing of entries when the FIFO list
depth is exceeded.

When Code Filter is set to Tx Line an internal list is
managed where each entry is flushed when the Tx Line
distance is exceeded.
The application program inherently compares codes based
on content and code length.
Each Code Filter criteria has its own relative value parameter.

Disable: No additional criteria are applied. If code filtering
is enabled through the Code Filter Depth parameter, the
FIFO list is only modified by new code entries (FIFO list
depth exceeded).

Timeout: A timeout measured in milliseconds is also
applied to each code entry. The current code entry will be
flushed from the list when the timeout expires.

Encoder Steps: a threshold measured in encoder steps is
also applied to each code entry. The current code entry will
be flushed from the list when the number of encoder steps
is exceeded.

Tx Line: The distance measured in mm to the transmit line
is applied to each code entry. The current code entry will be
flushed from the list when the distance in mm is exceeded.
When Tx Line is selected, all the networked scanners must
have been calibrated using PackTrack (See section 5.6
PackTrack).
NOTE:
The Code Filter Depth parameter is no longer
available because the application program
manages an internal list which depends solely
on the number of codes decoded before the Tx
Line is reached.
Any code which is determined to be identical to
a code in the list by comparing the filter
conditions will be discarded, and to increase
precision the code in the list will have its x, y, z
position coordinates adjusted as the average
between the two readings.
