Configuration: Scanner Control, Primary Match Table, Discrete I/O

Publication 2755-833

If an invalid operation occurs (decoder is unable to
decode a symbol in a package), it will wait for the
next package.

For each match code entry, the decoder:

if Symbology is Any, the decoder changes the
setting of the Symbology parameter to match the
symbology of the first symbol read

loads the match code string

changes output condition to Match-Entry

If the bar code data contains the ”%” character, the
decoder displays %% in the match code table, but
records a single % in the data. Use the ”%” character
to enter any non-printable character. For example,
%M represents CTRL-M, or carriage return. See
Appendix I.

ATTENTION: It is good practice to save your
configuration once the required AutoLoad parameters
have been set. Doing so assures you will retain key
AutoLoad parameters even after lengthy periods
without power.

AutoLoad (INPUT) Configures discrete input/output 8 for

AutoLoad (INPUT). This function requires an input
module in position 8 of the I/O Module Board, or
connection of the appropriate pins on the AUX port.
(Appendix H shows how to wire the input module in
I/O location 8 to a normally open contact.)

Important: AutoLoad (INPUT) requires that you
configure one or more of the other outputs (1-7) for
AutoLoad.

You can restore the AutoLoad condition to outputs
configured (and saved) for Autoload by applying the
appropriate input voltage to module 8. Refer to
Chapter 4 for more information.

The AutoLoad (INPUT) condition serves two
functions:

1. Activates AutoLoad Activates the AutoLoad
function without restarting the system (via the Select
Operation menu or host command). Refer to the
examples for more information
