Setting the Program Parameters
Caution:
Some host terminals can corrupt the RealScan 7872 program if they are
running and are connected to the RealScan 7872 while you are making program
changes. Either turn off the host terminal or disconnect the interface cable before
scanning any programming tags.
To make changes to the program parameters, enter information from the Programming
Worksheets located toward the back of this book. The Programming Worksheets
identify all the available program parameters. Each worksheet relates to a specific
programming mode. Most programming options have defaults, identified by a heavy
box, that are determined at the factory. Scanning the
Default
tag as the first tag after
applying power to the unit sets the parameters to these values.
Changing the RealScan 7872 program is accomplished by scanning the proper sequence
of programming tags. Following are three major steps for making program changes.
1.
Enter the Base Programming state by scanning the
Programming Mode
tag; must be
first tag scanned after applying power.
2.
Select a Programming Worksheet and enter its parameter data by scanning the
appropriate Hex tags.
3.
Save the program by scanning the
Save and Reset
tag.
Note:
In most cases the factory determined defaults are the correct parameter setting.
However, if you do need to make changes, it is recommended that you first set all
parameters to default values and then make any necessary changes to the appropriate
parameters.
