Chapter 7: Programming 7-9
Program Entry Example
The following example is a typical program entry procedure.
1.
Apply power to the NCR 7870 Scanner/Scale.
2.
Scan the Programming Mode tag.
3.
Scan the two Hex tags corresponding to the worksheet number.
4.
Scan appropriate Hex tags to enter parameters. Two methods are
available:
a)
Enter All Parameters
To enter all parameters in a Specific Programming Mode, scan
the two Hex codes that put the NCR 7870 in the specific mode,
and then make parameter changes in the order described on the
programming worksheet for that mode. In programming all
parameters in a specific mode, you proceed linearly through the
work sheet. When you make a change in a parameter, the
scanner moves to the next parameter to be changed or it goes
back to the Base Programming State if your selection ends
programming in that particular Specific Programming Mode.
The following figure shows how to proceed through a Specific
Programming Mode where you choose to enter all parameters.
This figure presents the Specific Programming Mode for the Bar
Codes 2 program parameters. The figure shows how you
proceed through the specific mode by entering all available
parameters. Notice that if you choose to disable Code 39 bar
codes, programming immediately return to the Base
Programming State. However, if you select to enable Code 39
bar codes, the scanner directs you to continue entering
parameter information.
