Rockwell Automation 2755 Enhanced Decoder Series B - Manual (Page 77)

6–4 Configuration: Symbology
Publication 2755-833
We recommend that you enter specific lengths for Interleaved 2-of-5
labels. Otherwise, a partial scan of symbols could result in a valid
shorter read.
The decoder will ignore 2 character Interleaved 2-of-5 labels unless
you enter a specific length of 2.
Interleaved 2-of-5 Check Character
Field Type Options
Select
No
Yes
Controls whether the decoder is required to compute and verify a
code check character for Interleaved 2 of 5 bar codes. The code
check character ensures that the data is read correctly. The default is
No, which means the decoder treats all decoded characters as data.
The Interleaved 2 of 5 character is computed as a Modulus 10 sum of
all characters value as specified in the AIM specification USS-I 2/5.
Include Interleaved 2-of-5 Check Character
Field Type Options
Select
No
Yes
Controls whether the Interleaved 2 of 5 check character computed by
the decoder is included in the message sent to the host. The default is
No, which means the Interleaved 2 of 5 check character is not sent.
Interleaved 2-of-5 Guard Bars
Field Type Options
Select
No
Yes
Controls verification of the presence of guard bars on Interleaved
2-of-5 symbols. The default of No results in no verification. Select
Yes to activate guard bar verification.
