Wand Emulation Interface 10 - 5
Leading Margin (Quiet Zone)
Scan a bar code below to select a leading margin duration. A leading margin is the time that precedes the first bar
of the scan, in milliseconds. The minimum allowed value is 80 msec and the maximum is 250 msec. Use this
parameter to accommodate older wand decoders that cannot handle short leading margins.
NOTE 250 msec is the maximum value that this parameter can attain, however, 200 msec is sufficient.
