Modify Settings > Advanced
The Advanced screen provides filters for enhancing the scanners ability to
read a bar code. Adjusting these values may have a negative or positive
effect on the reader’s ability to decode a bar code.
The Data Filtering, DRX (Data Reconstruction) and Transmit QQ settings are
considered advanced settings because they require comprehensive training
to understand how they should be modified.
NOTE:
Changing the Advanced settings can adversely
affect reader performance. These settings are to be modified
only under the guidance of Accu-Sort Technical Support.
Data Filtering
The data filtering parameters specify the minimum and maximum pulse width
(in counts) for the bar code data. This important data filter setting assures
optimal reader performance. The Sampling Frequency default of 100 Mhz
assures better decoder resolution for poorly printed bar codes.
Scan Filtering (Skip Scan) –
•
This option is used on applications that have slow conveyance
and/or reading bar codes with a large bar height. Under these
conditions the reader fills its memory with so much data that it does
not have time to process all the data before the end of trigger,
causing the reader to no-read. The Scan Filtering (Skip Scan) option
limits the amount of data, allowing the reader to processing less data
and give it a more of an opportunity to read the bar code.
Minimum Transitions –
•
There have to be a certain number of bars and spaces detected on a
scan line in order to consider the information valid. This option
restricts data from being placed into memory.
