Programming Considerations
Your 7890 Presentation Scanner is fully programmable
to meet your system requirements.
When you receive your 7890 scanner, it is already
programmed with default values set at the factory.
However, if you do need to make programming
changes, the procedure is very simple. First you fill-in a
series of programming worksheets, then you enter the
information using special programming tags. You can
also clone (copy) a program between scanners if you
have several that require the same parameters.
The Programming Worksheets (refer to Appendix A) are
the focal point for writing a 7890 Scanner program. The
worksheets contain parameters that you select for your
specific needs. The information is presented in a logical
sequence, making it easy for you to select the required
parameters. A place is provided at the bottom of each
worksheet for you to enter your selections, creating
your program. Each worksheet relates to a specific
programming mode.
After completing the worksheets, you enter the
information using the special programming tags (refer
to BST0-2121-74). You do not need a large number of
special programming tags, only 5 unique tags and 16
hexadecimal (Hex) character tags. The following chart
identifies each programming tag, its function, and the
associated indicators.
