V440-F C-Mount Code Reader User Manual
I-2/5 has been popular because it is the most dense symbology for printing
numeric characters less than 10 characters in length; however, Omron
Microscan does not recommend this symbology for any new applications
because of inherent problems such as truncation.
A dense, continuous, self-checking, numeric symbology. Characters are
paired together so that each character has five elements, two wide and
three narrow, representing numbers 0 through 9, with the bars representing
the first character and the interleaved spaces representing the second
character. (A check character is highly recommended).
Important: You must set Symbol Length in order to decode I-2/5 symbols,
unless Range Mode is enabled.
<K472,status,check character status,check character output status,symbol
length #1,symbol length #2,guard bar status,range mode status>
Enabled
0 = Disabled
1 = Enabled
This option is not typically used, but it can be enabled for additional security
in applications where the host requires redundant check character verifica-
tion.
An error correcting routine in which the check character is added.
<K472,status,check character status,check character output status,symbol
length #1,symbol length #2,guard bar status,range mode status>
Disabled
1 = Enabled
0 = Disabled
When enabled, a check character is sent along with the symbol data for
added data security.
<K472,status,check character status,check character output status,sym-
bol length #1,symbol length #2,guard bar status,range mode status>
Disabled
1 = Enabled
0 = Disabled
Useful in applications where I 2/5 symbols of a specific length are
required.
The Symbol Length # 1 field is one of two fields against which the
decoded symbol is compared before accepting it as valid or rejecting it.

16
0 to 64, even only
Important: If Range Mode is disabled, the length of the symbol must
match either Symbol Length # 1 or Symbol Length # 2 to be considered
a valid symbol.
If Range Mode is enabled, Symbol Length # 1 and Symbol Length # 2
form a range into which the length of the symbol must fall to be considered
valid.
