Symbologies
Range Mode Status
Important: Unless Range Mode is enabled, Symbol Length must be set to decode
Interleaved 2 of 5 symbols.
Useful in applications where Interleaved 2 of 5 symbols of a specific length are required.
When Range Mode is disabled, the scanner 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.
