Publication 2755-833
The corresponding output counter increments each
time the buffer overflow condition occurs.
AutoLoad Configures the specified output to load bar code data
from the first valid package(s) into the match code
table.
After configuring one or more outputs for
AutoLoad, you can activate AutoLoad in one of
three ways:
1. Restart system (using Select Operation menu or
host command). Refer to the examples for additional
information.
2. Configure Output 8 for AutoLoad (INPUT) and
apply the appropriate input voltage to the input
module in I/O location 8. See AutoLoad (INPUT)
and Appendix H.
3. Connect a normally opened (N.O.) contact to
specific pins in the AUX connector as shown in
Appendix H. The AutoLoad function activates when
the contacts close.
Note: This method does not require an I/O Module
Board with an installed input module.
Note: The first Autoload does not increment the
counter.
After activating the AutoLoad function, and if the
Symbology parameter is set to Any, then bar code
fields (32 characters maximum) are sequentially
loaded into the match code table until one of the
following occurs:
•
Symbols/Package setting is satisfied. If the
number of outputs configured for AutoLoad is
greater than the symbols/package setting, the
Autoload function will fill entries until the
symbols/package setting is satisfied. See
AutoLoad (INPUT), below, for an explanation
of how to load match code data into the table
where the number of match codes is greater than
the value of the Symbols/Package parameter.
•
All entries (configured for AutoLoad) are filled.
NOTE: If the Symbology parameter is set to
anything other than Any, then only symbols of the
currently selected symbology will be AutoLoaded.
