NCR 7870 Scanner User Manual


 
A-2 Appendix A: Programming Worksheets
Defaults
Most of the programming parameters have defaults that are
determined at the factory. A heavy box around an entry specifies it as
a default value. Scanning the Default tag as the first tag after applying
power to the 7870 sets the parameters to these values.
Hex Characters
Some of the programming parameters require Hex characters. Refer to
the
ASCII Code Chart
for the proper selections.
Program Entry
Some host terminals can corrupt your program if they are running and
are connected to the 7870 while a program is being entered. Either turn
the host terminal off or disconnect all interface cables to the 7870 before
entering the program.
1.
Enter the Base Programming state by scanning the Programming
Mode tag. This must be the first tag scanned after powering up the
7870.
2.
Select a Programming Worksheet and enter its parameter data by
scanning the Hex tags identified in
Your Program
at the bottom of
the Programming Worksheet. Repeat this for each Worksheet.
3.
Save the program by scanning the Save and Reset tag.
