Datamatrix DPM Decoding Safety
Decoding Safety is used to configure a decoder to be very aggressive to very
conservative, depending on a particular customer’s needs.
• Level 1 results in a very aggressive decoder.
• Level 5 results in a very conservative decoder at the expense of not
being able to read poorly printed or damaged labels.
There are many factors that determine when to change the decoding safety.
These factors include spots, voids, non-uniform backgrounds, damaged
labels, etc. that may be experienced in some barcode labels. If there are
many hard to read or damaged labels that cannot be decoded using a con-
servative setting, decrease the decoding safety to be more aggressive. In
case of rigorous reliability application requirements it is suggested to use
higher decoding safety values (conservative).
Set Length
Length Control allows you to select either variable length decoding or fixed
length decoding for the specified symbology.
Variable Length:
For variable length decoding, a minimum and maximum
length may be set.
Fixed Length:
For fixed length decoding, two different lengths may be set.
Set Length 1
This feature specifies one of the bar code lengths for Length Control. Length
1 is the minimum label length if in Variable Length Mode, or the first fixed
length if in Fixed Length Mode. Length includes the bar code’s data charac-
ters only.
The number of characters that can be set varies, depending on the symbol-
ogy. Reference the page for your selected symbology to see specific vari-
ables.
1. Determine the desired character length (varies depending on symbol-
ogy). Pad the number with leading zeroes to yield two digits. For exam-
ple: 0 = 00, 5 = 05, 20 = 20, etc.
2. Go to the Set Length page for your selected symbology and scan the
ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mode.
3. Scan the bar code to SELECT LENGTH 1 SETTING for your selected sym-
bology.
4. Scan the appropriate two digits from the keypad in
, that represent the length setting which was determined in the
steps above. You will hear a two-beep indication after the last charac-
ter.
If you make a mistake before the last character, scan the CANCEL bar code to
abort and not save the entry string. You can then start again at the begin-
ning.
