Interleaved 2 of 5
Guard Bar Status (Interleaved 2 of 5)
Note: Whenever Guard Bar is enabled, the presence of guard bars (also called “bearer
bars”) is required for decoding to take place.
Range Mode Status (Interleaved 2 of 5)
Usage: Useful when I-2/5 multisymbols are enabled to prevent false data output.
This typically occurs with highly tilted or skewed symbols.
Definition: A guard bar is a heavy bar, at least twice the width of the wide bar, surrounding
the printed I-2/5 symbol and helping to prevent false reads.
Serial Cmd: < K472, status,check character status,check character output,symbol length
#1,symbol length #2, guard bar status ,range mode status >
Default: Disabled
Options: 0 = Disabled 1 = Enabled
Usage: Useful in applications where I 2/5 symbols of a specific length are required.
Definition: When Range Mode is disabled, the reader checks the value of the symbol
length against the values set in Symbol Length # 1 and Symbol Length #
2 . If the symbol length does not match either of the preset values, then it is
rejected as invalid.
When
Range Mode is enabled, Symbol Length # 1 and Symbol Length #
2 are combined to form a range of valid symbol lengths. Any symbol length
that does not fall into this range is rejected as an invalid symbol. Either of
the preset symbol length values in the Symbol Length # 1 and Symbol
Length # 2 fields can form the start or end of the range.
Serial Cmd: < K472, status,check character status,check character output,symbol length

Default: Enabled
