Configuring Your Decoder

-or-
•
An invalid operation has occurred (no-read, required symbology not
enabled, improper bar code length, etc.). If any field within the package
cannot be decoded, all fields will be ignored and the decoder will wait for
the next package.
For each match table entry that is filled, the decoder will:
•
Automatically set the bar code symbology.
•
Change the match code enable to YES.
•
Enter match code string into the match table.
•
Change output condition from Auto Load to Match-Entry In Table.
•
Send the match code string to the AUX port if at the select language
screen. This provides the ability to monitor the auto loaded string at any
display device connected at the AUX port.
Note:You must SAVE the configuration and RESTART the decoder after
auto loading if you want the newly loaded match codes to be stored in
EEPROM.
Enable auto load in one of two ways:
•
Enable the auto load condition for one or more outputs and perform a
SAVE and a RESTART. You can RESTART the decoder by cycling the
power, sending a RESTART command from the host, or selecting
RESTART at the Select Operations menu of the programmer CRT.
•
If you have Auto Load (INPUT) selected for module #8, an auto load
input signal can be sent to an input module in the #8 position. This signal
activates the input module which enables the auto load. Refer to Input
section below for more information.
Note: When Auto Load is enabled, only the bar code fields from the first
valid package are entered into the match table. Auto Load is then disabled
until the next RESTART or Auto Load (INPUT) signal is detected.
Note: When you auto load a “%” character, the decoder will automatically
enter “%%” into the match table. The “%” character is used to enter
non-printable control characters. Refer to page 4-14.
Inputs
Auto Load (INPUT): The Auto Load (INPUT) condition only applies to
module position #8. This module position is unique and can accept either an
input or an output module. Selecting Auto Load (INPUT) configures module
position #8 to accept an input module. Otherwise, module position #8
functions the same as module positions 1 through 7.
When you select the Auto Load (INPUT) condition for module #8, make
sure that at least one of the output conditions for modules #1 through #7 is
configured for Auto Load and SAVED to EEPROM. Auto Load (INPUT)
changes outputs #1 through #7 (if configured for Auto Load) by clearing out
