Scale Parameters

The Scale Parameters Parameter Programming Mode controls specific parameters associated with a NCR 7879 that has a scale. This mode can be used to identify if the NCR 7879 includes a scale and to define the address if the scale is connected to an Host terminal. The default values are shown in the Red boxes and also in the Parameter Defaults section earlier in this chapter.

Model

The Model parameter specifies if the NCR 7879 is a Scanner/Scale or a Scanner only. This parameter is set at the factory and should not need changing under normal circumstances. Scan the Hex 3 tag to specify that the unit is a Scanner/Scale, or scan the Hex 4 tag to specify that the unit is a Scanner only. If the scale is disabled on a Scanner/Scale unit by scanning the Hex 4 tag, the BCC option also changes to the appropriate state.

IBM Address

When programming a NCR 7879 for IBM communications, the proper scale communications address must be selected. Selecting the IBM 468x communications protocol sets the scale address to 6E; however, it may need to be changed to 6A or 6B, depending on the IBM configuration in the particular IBM host terminal software. Scan the Hex 5 tag for address 6A, the Hex 6 tag for address 6B, or the Hex 7 tag for address 6E.

The IBM host terminal integrated Scanner/Scale driver normally uses address 6E. However, if the scanner works but the scale does not, try using the other two scale addresses.
