Code Filter
Depth In Continuous mode , Code Filter Depth is used to avoid multiple
reads of the same code. The entered value (other than zero)
defines the number of codes to memorize in a FIFO (First In First
Out) list.
When a code is read, it is compared to the list. The application
program inherently compares codes based on content and code
length. If the list contains a code identical to the current code being
read, the current code is discarded. If not, the current code is
accepted and added to the list in the first position; the remaining
codes in the list are shifted. If the list is full the oldest code in the list
will be flushed.
When = 0, there is no FIFO list and there is no filtering.
Selection: a value from 0 to 127
Example:
Code Filter Depth = 3
List Code Read Accepted
xxx (no codes in list) A Yes
Axx B Yes
BAx B No
BAx C Yes
CBA D Yes
DCB A Yes
ADC A No

Steps
Enter a number of encoder steps from 1 to 15000. This parameter
sets the number of Encoder Steps after which the
FIFO (First In
First Out) list entry is flushed.

Select the check box to enable a further code filter condition
according to which a read code is added to the list or discarded.
This parameter is available if the
Code Filter Depth value is other
than zero or if the Code Filter value is Tx Line.
In addition to the inherent content and code length comparison, this
parameter compares the code type (symbology). If the current code
being read is identical to any code contained in the list by: content,
length and type, the current code is discarded. If not, the current
code is accepted and added to the list in the first position; the
remaining codes in the list are shifted. If the list is full the oldest
code in the list will be flushed.
