1D Quiet Zone Level
Parameter # 1288 (SSI # F8h 05h 08h)
This feature sets the level of aggressiveness in decoding bar codes with a reduced quiet zone (the area in front
of and at the end of a bar code), and applies to symbologies enabled by a Reduced Quiet Zone parameter.
Because higher levels increase the decoding time and risk of misdecodes, Symbol Technologies strongly
recommends enabling only the symbologies which require higher quiet zone levels, and leaving Reduced
Quiet Zone disabled for all other symbologies. Options are:
• 0 - The imager performs normally in terms of quiet zone.
• 1 - The imager performs more aggressively in terms of quiet zone.
• 2 - The imager only requires one side EB (end of bar code) for decoding.
• 3 - The imager decodes anything in terms of quiet zone or end of bar code.
