5-22 Chapter 5: Programming
Tone Frequency (Hertz)
The Hex B tag sets the frequency of the Good Read tone. Each time the Hex B tag is scanned,
the tone increments one unit. After reaching the highest frequency, the sequence starts over
with the lowest frequency. End this mode by scanning the End tag or another valid Hex tag.
The Good Read Tone frequency can have one of the following eight values:
3348 Hz
2976 Hz
2679 Hz
2435 Hz
2232 Hz
3906 Hz
3750 Hz
3538 Hz
Tone Length (Milliseconds)
The Hex C tag sets the length of the Good Read Tone. Each time the Hex C tag is scanned, the
tone length changes from the shortest to the longest, and then back again. End this mode by
scanning the End tag or another valid Hex tag.
The Good Read Tone length is from 15 ms to 225 ms in 15 ms increments
(15 total values).
Tone Volume
The Hex D tag selects the volume of the Good Read tone by increasing it as the Hex D tag is
repeatedly scanned. After the loudest volume is reached, the sequence begins again with the
softest volume. End this mode by scanning the End tag or another valid Hex tag.
There are eight different volume settings available on the 7893. However, there is a
programming sequence which allows the user to access eleven volumes. Refer to the Volume
Adjust section in this chapter for details on activating the eleven volumes and other functions
of the volume button.
Not-On-File Volume
The Hex E tag sets the volume of the Not–On–File tone by listening to it as the Hex E tag is
repeatedly scanned. The new tone sounds for two seconds. End this mode by scanning the End
tag or another valid Hex tag.
The Not-On-File tone goes off when the scanner receives a command from the host terminal to
do so. In RS-232 protocol, there is a Not–On–File command. Refer to the NCR Scanner/Scale
Interface Programmer's Guide (BD20-1074-A) for more information about the Not-On-File
command.
