NCR 7870 manual Special Programming, Delay Weight Data to IBM Host Terminal

7-68 Chapter 7: Programming

Special Programming

Some of the NCR 7870 features require programming that is somewhat different than the normal programming.

Delay Weight Data to IBM Host Terminal

A timing condition is possible when the NCR 7870 Scanner/Scale communicates with an IBM host terminal. The condition occurs when the IBM Host is requesting weight data, but the scale is not settled. To prevent the problem, you can enable a scale data delay function that gives the scale more time to settle. The default for this parameter is to disable the Scale Data Delay. Enable or disable the Scale Data Delay by scanning the following sequence of programming tags as the first tags scanned after applying power to the NCR 7870.

Enable – Programming Mode, Hex 4, Hex C, Hex E, Hex 2, Hex 9, Hex 4, Hex E, Hex 8, Hex 0, and Save and Reset.

Disable – Programming Mode, Hex 4, Hex C, Hex E, Hex 2, Hex 9, Hex 4, Hex E, Hex 0, Hex 0, and Save and Reset.
