Timers

The Timers programming mode controls the two NCR 7875

Scanner/Scale timers: Lockout Time and Active Time.

Defaults

Parameter	Default Value
Lockout Time	900 milliseconds
Restart Lockout Timer	Off
Active Time	15 seconds
Specific Program Parameters

Lockout Timer (Milliseconds)

The lockout timer prevents the scanner/scale 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/scale can read the same bar code again. The Lockout Time parameter selects the lockout time.

There are 8 different times ranging from 450 milliseconds to

1500 milliseconds in increments of 150 milliseconds. Select these times using the Hex 0 through Hex 7 tags. The default time is

900 milliseconds.

Restart Lockout Timer

The Restart Lockout Timer parameter controls restarting the lockout timer each time the scanner/scale reads the same bar code. Turning on the Restart Lockout Timer option has the following effect. After reading a bar code, if the bar code moves out of the scan pattern and then back into the scan pattern before the lockout timer times out, the lockout timer restarts. The Hex 0 tag turns off this option and the Hex 1 tag turns it on. The default is off.
