Chapter 7: Programming 7-5
Programming Mode
The NCR 7870 Scanner/Scale is programmed in the Programming
Mode. You enter this mode by scanning the Programming Mode tag as
the first tag scanned immediately after applying power to the NCR
7870. This puts the NCR 7870 in the Base Programming State. As a
result, the NCR 7870 produces a long and then a short beep, and the
status indicator stays off.
From the Base Programming State you select Specific Programming
Modes by scanning the proper combination of two hexadecimal tags.
The program parameters that you can enter in a Specific Programming
Mode are identified on the associated programming worksheet.
In each Specific Programming Mode you can enter all the information
contained on the worksheet by scanning the proper tags in the
sequence shown on the worksheet. However, you can also use
parameter shortcuts to enter only specific parameters. Program entry
then goes directly to a specific parameter when you scan the proper
Hex tag.
The NCR 7870 accepts programming tags only in the Programming
Mode. If you scan a programming tag during normal operation,
nothing happens.
