Useful in applications where I 2/5 symbols of a specific length are
required.
The Symbol Length # 2 field is one of two fields against which the
decoded symbol is compared before accepting it as valid or rejecting it.

0 to 64, even only
Important: If Range Mode is disabled, the length of the symbol must
match either Symbol Length # 2 or Symbol Length # 1 to be considered
a valid symbol.
If Range Mode is enabled, Symbol Length # 2 and Symbol Length # 1
form a range into which the length of the symbol must fall to be considered
valid.
Useful when I-2/5 multisymbols are enabled to prevent false data output.
This typically occurs with highly tilted or skewed symbols.
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.

Useful in applications where I 2/5 symbols of a specific length are required.
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.
