Timeouts
Controls Lockout Time and Active Time.
Prevents repeatedly reading the same bar code. After a bar
code, is read, it must be removed from the scan pattern and
the lockout time must elapse before the same bar code can be
read again.
Eight different lockout times are available ranging from 450
milliseconds to the maximum value of 1500 milliseconds. The
default value is 750 milliseconds. You select times using the
Hex 0 through Hex 7 tags.
Restarts the Lockout Timer each time the same bar code is
read. If the bar code moves out of the scan pattern and then
back into the scan pattern before the lockout time elapses, the
Lockout Timer restarts. The Hex 0 tag turns this option off.
The Hex 1 tag turns it on (default value).
Specifies length of time that the unit stays on after the last
good read. Set this value to be long enough for the consumer
to pick up and scan the next item. However, keep in mind that
you want to minimize the amount of time the laser is on.
Nine options range from 5 seconds to 45 seconds in
increments of 5 seconds. To select the Active Time, use the
Hex 0 through Hex 8 tags. The default time is 30 seconds.
