Chapter 5:
Programming
This overview of programming the 7893 is intended to acquaint you with the overall
programming procedure. The “Scanner Programming Summary” section at the end of this
chapter is most useful after you have performed the programming function.
Programming Mode
To program the 7893, it must be in the Programming Mode. Enter this mode by scanning the
Programming Mode tag immediately after applying power to the scanner; it must be the first
tag scanned. This puts the scanner in the Base Programming state. When entering the Base
Programming state, the scanner produces a long then short beep; the LED Status Indicator
stays off. If speech is enabled, the scanner says “Program Mode”.
From the Base Programming state, select specific programming modes by scanning the proper
two hexadecimal tags. The program parameters that you enter in a specific programming mode
are identified on the associated Programming Worksheet.
In each specific programming mode, enter all the information contained on the worksheet by
scanning all the proper tags in sequence as shown on the worksheet. In addition, use parameter
shortcuts to enter a specific parameter. Program entry goes directly to a specific parameter
when you scan the proper Hex tag.
If you do not know how your 7893 is programmed, you can set it to all defaults then enter any
required changes to match your program. Do this by scanning the Default tag as the first tag
after applying power to the scanner. This sets the defaults for the programmed default setting
in the scanner. Next, scan the Programming Mode tag to enter the Programming Mode.
The scanner accepts programming tags only in the Programming Mode. If you scan a
programming tag during normal operation, nothing happens.
Preparing for Your Program
Determine the requirements for your program, such as communications protocol, use of good
read tone, timeouts, bar code types, label identifiers, RS-232 requirements (if using this
protocol) and defaults. You may need to read your system application documentation.
Completing the Worksheets
Programming parameters are contained in the Programming Worksheets. Before using the
worksheets, read the “Using the Programming Worksheets” sectionat the beginning of
Chapter 7.
