Timers
NOTE:
NCR suggests that you do not set the Active Time
parameter to 0. Leaving the laser light on all the time reduces
its life expectancy.

NOTE:
Direct Entry Only.
If the Restart Lockout Timer [B] is set to OFF,
the 900 ms Lockout Timer Restart Limit [F]
has no effect.
The Timers programming mode controls the two 7893 timers: Lockout Time and Active Time.
Refer to the “Parameter Defaults” section earlier in this chapter for the factory defined default
value of each programming parameter.
Lockout Time
The lockout timer prevents the scanner from repeatedly reading the same bar code. After
reading a bar code, it must be removed from the scan pattern and the time programmed in the
lockout timer must elapse before the scanner can read the same bar code again. The Lockout
Time parameter selects the lockout time.
There are 9 specific times ranging from 350 milliseconds to 1500 milliseconds. Select these
times using the Hex 0 through Hex 8 tags.
