5-2 Chapter 5: Programming
You need to know the communication protocol that your host terminal is using so that you can
program your 7893 to the same protocol. If you are unsure of the setting in your scanner, scan
the
Default tag. The unit should make one long beep followed by the number of beeps
corresponding to the communication protocol. (See Chapter 3 in this manual.) If this is not the
desired default, program the communication protocol first, and then program any additional
parameters using the programming tags and worksheets.
The Programming Worksheets identify the default values that are determined at the factory.
You only need to use the worksheets that need changing for your particular requirements.
Enter your program at the bottom of each worksheet. Be sure to read the sections later in this
chapter that relate to the worksheets you are using.
Entering Your Program
Enter your program by performing three basic steps:
1. Enter the Base Programming state by scanning the Programming Mode tag first
after applying power to the 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 used if the default is changed.
3. Save your program by scanning the Save and Reset tag.
