Step 6 – Set Program Parameters
Now you need to make any necessary programming changes to the RealScan 7875. The
RealScan 7875 does not have an On/Off switch. Use the circuit breaker switch in the checkstand
that supplies power to the unit as the On/Off switch.
Setting the Program Parameters
Caution:
Some host terminals can corrupt the RealScan 7875 program if they are running and
are connected to the RealScan 7875 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, which 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 7875 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 then make any necessary changes to the appropriate parameters.
