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.

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.
