DELETE LINE JS<ENTER>n

This command allows you to delete the nth 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.

CLEARJX<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.
