Data Editing Formulas
The set of instructions programmed into the Omni to edit the data record is referred to as the data editing “formula.” More than one formula can be resident in the reader at one time. If more than one formula resides in memory, the reader will apply the first formula to the input data. If the scanned data matches the format (credit card, driver’s license, etc.) of the first formula, then it will apply the data editing functions and output the reformatted data to the host. If the data does not match the criteria spelled out in the first formula, then the criteria of the second formula is applied. This process continues for each of the successive formulas until a match is found. If no matches are found to any of the formulas programmed into the reader, then either nothing will be transmitted to the host, unless the “Send Unmatched” mode is enabled, in which case the input data will be transmitted in its original format.
The number of formulas that can be entered into the Omni is limited by the amount of memory available. Caution should be used when entering a number of long formulas as the amount of
The Formula Sequence
A basic data editing formula for the Omni has the following structure. (The optional commands are enclosed in brackets):
CODE ID | [LENGTH][MATCH]DIVIDE[ADD]SEND |
In other words:
1.Identify the bar code symbologies to which this formula will apply.
2.Specify length parameters (if desired).
3.Specify the characters (if any) you would like to match.
4.Indicate how you want to divide the data record.
5.Add a character string (if desired).
6.Send the edited data record to the host computer.
Multiple conditions may be programmed for each major group of commands (i.e. several code IDs can be used following the CODE ID command), but all like commands must be grouped together. For example, several ADD commands can be programmed, but all of them must be grouped together and placed prior to the SEND command.
Note: If Function Codes are to be used with any of the commands, the Function Code capability must be enabled by typing B7<ENTER>A<ENTER> before entering the Data Editing Setup mode.
