DELETE LINE JS<ENTER>n
This command allows you to delete the n th formula stored in data
editing memory. In this command, “n” is a numeric digit (such as 2 or 3)
that represents the formula to be removed.
CLEAR JX<ENTER>
Entering the CLEAR character from the Data Editing Menu will remove
all the data editing formulas from the decoder memory, disable the data
editing feature, and set the UNMATCHED INPUT option to DO NOT
SEND.
REVIEW CONFIGURATION
JY<ENTER>
Entering the REVIEW CONFIGURATION command will send the
resident data editing formulas—each on its own line—and all other
data editing settings to the host computer, allowing you to review the
settings. The reader must be connected as a keyboard wedge, or
connected to an RS-232 serial port running software that takes RS-232
input and places it in the keyboard buffer, for the information to be
displayed on screen.
EXIT DATA EDITING JZ<ENTER>
After the data editing formula has been created and reviewed, entering
the EXIT command will terminate the DATA EDITING SETUP mode and
return the Omni to normal operation.

Data Flow
The Omni processes input data in the following order:
1. Raw scan input data is decoded and placed in an ASCII character
format in the
memory of the reader.
2. The symbology and magnetic track tests (maximum /minimum length,
check digit, send sentinels, etc.) are applied to the scanned input.
3. Following a successful completion of these tests, the input record
data is processed by the data editing formula, if enabled.
4. If the input data “matches” one of the resident data editing formulas,
it is processed and sent to the output port. If not, and the UN-
MATCHED INPUT function is set to DO NOT SEND and input data is
discarded.
5. If UNMATCHED INPUT is set to SEND, the “unmatched” input data
is passed on to the message processing section of the reader, where
any previously defined postamble, preamble, and terminator characters
are added before transmission.
6. If the data editing mode is enabled and UNMATCHED INPUT is set
to DO NOT SEND, no data is passed to the output port unless it
“matches” exactly one of the data editing formulas.
Note: No data formatting (i.e. postamble, preamble, or terminator
character) is done when the data editing feature is enabled.
