Good Read Tone

The Good Read Tone Parameter Programming Mode selects the parameters for sounding a tone each time the NCR 7879 successfully reads a bar code. It also controls the volume of the Not-On-File tone. This mode contains five shortcuts: A, B, C, D, and E. After entering this Parameter Programming Mode, proceed directly to a specific parameter by scanning the appropriate shortcut Hex tag. This eliminates the need to enter all parameters when only one needs changing. The default values are shown in the Red boxes and also in the Parameter Defaults section earlier in this chapter.

Tone On/Off

The Hex A tag selects the Tone On/Off programming parameter, which offers two options, On and Off. The Hex 0 tag turns the Good Read Tone off and the Hex 1 tag turns the Good Read Tone on.

Tone Frequency (Hertz)

The Hex B tag sets the frequency (tone) 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:

•702 Hz

•781 Hz

•868 Hz

•961 Hz

•1071 Hz

•1187 Hz

•570 Hz

•633 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 NCR 7879. 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.
