Same Symbol Re-Scan

The scanner is programmed with a same symbol timeout.
For SHORT SAME SYMBOL RE-SCAN, the time delay
is ½ second, while the LONG SAME SYMBOL RE-
SCAN delay is 1 second. These numbers represent how
much time that a bar
code must be out of the scan field before that bar code can
be scanned again.

Identical Symbol Re-Scan Indicator

During the same symbol timeout, the LED's do not
provide an indication of when the unit is ready to
begin scanning the same symbol again. To program
a LED to flash when thepreset delay is over, configure
the scanner to Green LED Enabled.

1 vs 2 Scan Buffers

This feature controls the number of bar codes
considered for the purposes of the same symbol
re-scan. The default, 1 scan buffer only compares
new scanned data against the last bar code scanned.
2 scan buffers allow the scanner to test the last
2 bar codes scanned for same symbol re-scan
purposes.
