Chapter 5: Programming 5-5
1. Enter the Base Programming state by scanning the Programming Mode tag as the first tag
after applying power to your 7893 scanner.
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 your program by scanning the Save and Reset Tag.
Caution:
Some host terminals can corrupt your program if they are running and are
connected to the 7893 while you are entering a program. Either turn off the host terminal or
disconnect the interface cable from the host terminal before entering your program.
Note:
In most instances the factory determined defaults are the correct parameter settings.
Normally you only need to change a few of these parameters and do not need to enter all the
Programming Worksheets. When programming your scanner, it is recommended that you first
set all the parameters to default values by scanning the
Default tag, then make any necessary
changes to the appropriate parameters. If you need to change the Default protocol, program
that first.
