DB-9 connector at one end, and is connected to the reader at the other end. (An adapter can be used to connect to a DB-25 RS-232 port.) The USB/RS-232 version of the Omni is connected to one of the host’s USB ports. -
Page 9: Section 3. Configuration
Section 3 CONFIGURATION The Omni reader must be appropriately configured to your application. Configuration settings enable the reader to work with the host system. These settings are programmed into the reader through the keyboard. Once pro- grammed, these configuration settings are stored in the reader’s non-volatile memory (so they are not affected by the cycling of power). - Page 10 5. Press the <Enter> key. The reader will beep twice to indicate the reader is now in the Setup Mode for group X. 6. Type the two-character selection code for the feature that you wish to change. 7. Press the <Enter> key. The reader will beep twice to indicate the code is accepted by the reader as a valid code for Setup Group X.

Page 11: Default Settings
Default Settings The Omni reader is shipped from the factory with the default settings already programmed. In the following sections, the default settings are shown in boldface. For a list of all default settings, please see Appendix A. By default, the reader has been programmed with the least restricted settings, thus making the Omni reader able to read most bar code labels and standard format magnetic stripe cards out of box. -

Page 36: Section 4. Data Editing
Section 4 DATA EDITING In addition to adding preambles, postambles, and terminator characters, the Omni can also rearrange, drop, or add to the data it reads from a bar code or magnetic stripe. This enables the data to be sent to the host in the exact format expected by the application software, thus eliminating the need for software modifications. -
Page 37: Data Fields
Data Fields By separating decoded data into blocks known as “fields,” each block of data can be treated individually. Fields can also be added to the data, permitting user-required characters or function codes to be included. The fields are identified by a one-character ID starting with the character “A” (up to and including “Z”) in the order they were created. -
Page 38: Data Editing Formulas
Data Editing Formulas The set of instructions programmed into the reader to define data fields and than arrange them into a format is known as the data editing “formula.” A maximum of four formulas can be resident in the reader’s memory at any one time. -
Page 39: The Formula Sequence
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 and/or magnetic stripe tracks to which this formula will apply. 2. -
Page 40: Data Editing Functions
Using the Data Editing Functions The data editing function is often applied to driver’s licenses, where the magnetic stripe contains three tracks of information about the license holder, and the host application may need only certain details (such as name, address, and birth date) rather than all the data the stripe holds. -
Page 41: Data Editing General Commands
Data Editing Commands 1. Enter DATA EDITING mode by typing /E/D/FJ 2. Press <ENTER>. The reader should beep twice. 3.

- Page 43 Match String This command looks for a “match” between a data string designated in the data editing formula and a data string in the data scanned by the reader. When this feature is enabled, the only data sent to the host will be data that contains the matched data string.
- Page 44 Search for a Data String This command allows you to create a data field by searching the scanned data for a data string that matches a data string specified in the formula. If a match is found, the scanned data will be divided into three fields: the data from the search start point to the character before the searched data string, the data string itself, and the data remaining.
- Page 45 Set the Sequence in which Data Fields are Sent This command specifies the order in which data fields are transmitted to the host. Each separate field is assigned an upper case alpha letter in the order in which it is created. So the first data field created is A, the second is B, and so SELECTION CODE: JK Characters Assigned to Data Fields in the Transmission Order Desired EXAMPLE:...
