2. How do I verify that the reader works?
For a keyboard wedge interface (WCR3237-xxx) or USB/keyboard emulation interface (WCR3237-xxxU) unit:
a. Run any simple text editor - Notepad is recommended in the Windows environment (locate it through Start/All programs/Accessories/Notepad)
b. To verify the barcode readability: swipe a valid sample barcode through the slot. The reader should beep once and the barcode data should be displayed on Notepad screen (see the notes below)
c. To verify the magnetic stripe readability: for a dual track reader, swipe a credit card through the slot. The reader should beep twice & two lines of the data will show up in a Maximized Notepad window. For a triple track reader, swipe a driver license card, which has a magnetic strip with data encoded. The reader should sound 3 beeps, and at lease 3 lines of data will be displayed in the Notepad window
A For a RS232 serial (WCR3227-xxx) or USB/RS232 interface reader (WCR3227-xxxU):
a. Run HyperTerminal under Windows environment (Start/All programs/Accessories/Communications/HyperTerminal) and make a new connection.
b. Set up Hyper Terminal to communicate @ 9600, none, 8, 1, Xon/Xoff through the COM port where the reader is connected (Refer to General FAQs for instruction on how to setup the HyperTerminal correctly)
c. To verify the barcode readability: Scan a valid sample barcode. The reader should beep once and the barcode data should be displayed on the Hyper Terminal Screen
d. To verify the magnetic stripe readability: for a dual track reader, swipe a credit card through the slot. The reader should beep twice & two lines of the data will show up in a Maximized Notepad window. For a triple track reader, swipe a driver license card, which has a magnetic strip with data encoded. The reader should sound 3 beeps, and at lease 3 lines of data will be displayed on the Hyper Terminal Screen
1) The testing barcode needs to be positioned on the card so that it is centered about 1/2" from the bottom of the card for the Omni Combo unit. For a sealed unit, the center should be around 0.43"
2) If the reader does not beep when passing a barcode card through, please check and make sure the barcode is positioned correctly on the card. Also, make sure the barcode is facing to the barcode side of the slot
3) If the reader beeps, but no data is shown in Notepad, please check the connection
4) If the reader beeps, but either no data or wrong data was shown in HyperTerminal, please check connection & COM port settings in Hyper Terminal
5) If the scanner is verified as working, and does not function correctly with your application software, please contact the software supplier for the data format expected by the software. Re-configure the scanner's output accordingly.
3. How do I know what interface type is on my Omni Reader?
You can tell the interface type by looking at the cable that came with the reader:
A If the reader has a Y shape cable with a male type PS/2 connector on one end and a female type PS/2 connector on the other end, it's a keyboard wedge interface unit (Model: WCR3237-xxx or WCR3237-x00S)
If the scanner has the DB9 female connector on the end, it's a RS232 serial interface unit (Model: WCR3227-xxx for WCR3227-x00S)
If the scanner is a single ended cable with a flat USB connector on it, it is either a USB/KB emulation unit (Model: WCR3237-xxxU or WCR3237-x00US) or a USB/RS232 emulation unit (model: WCR3227-xxxU or WCR3227-x00US). Check the model # on the bottom of the unit to confirm the specific USB reader model type.
If the scanner has a single ended cable with just the tinned wires & without any connector, it is a Weigand interface unit (model: WCR3297-xxx)
If the scanner has a 9-pin squeeze to release type black connector on the end of the cable, it is an undecoded (TTL) interface unit (model: WCR3207-xxx)
Note: you can also refer to the General FAQ section for how to identify the products by model #
4. After programming the reader, my Omni reader gives multiple quick beeps when reading a card, but there is no data output, why is this?
A This is because the Omni is still in the program mode. Please exit the programming mode by sending 'save & exit setup' command for the particular setting group that you were in. As an alternative, cycle the power to the reader.
5. What software should I use to program the Omni Reader?
A For KB wedge interface unit (Model # WCR3237-xxx or WCR3237-x00S), we recommended to enter the configure command in Notepad to configure the reader.
A For USB/KB emulation unit (Model # WCR3237-xxxU or WCR3237-x00US), use the Omni USB Setup Utility software (USB Reader Setup Utility V3.1.zip)
A For RS232 (WCR3227-xxx or WCR3227-x00) or USB/RS232 emulation unit (WCR3227-xxxU or WCR3227-x00US), we recommend using Hyper Terminal to program the reader. (Refer to General FAQs for instruction on how to setup the HyperTerminal correctly)

7. My Omni keyboard interface reader works with an external keyboard attached, but it will not work when I remove the keyboard. Is there a way to make it work without having to connect an external keyboard?
You can configure the reader through the external keyboard in Notepad with the following code:
Then remove the keyboard, shut down the PC. Power up the PC and verify the reader's output again in Notepad.
8. How do I know if the code being taken correctly by the reader while programming the Omni reader? What else do I need to know when programming the reader through keyboard entry?
The reader should sound two slow beeps after all of the code commands except for the 'save & exit setup mode' commands.
For the 'save & Exit Setup Mode'command codes, which should always end with the letter 'Z' the reader will sound 4 slow beeps when Enter key is pressed.
The reader will sound 4 quick beeps to indicate any of the following errors:
1) If the command code entered is invalid
2) If the code has been corrected by using the Backspace key during typing
3) If a number key from the numeric keypad is used for the numbers in the code
To correct above problems,
1) Always, verify the code in the manual to ensure that it is a valid code.
2) Notice that the configure code is case sensitive. Type the code in slowly & correctly. If there is a typo, press the Enter key, and re-type the code correctly. (Do NOT use the Backspace key or any other key to correct the error).
3) Make sure to use the number keys above the main Alpha-keypad. Do Not use the number keys on the number keypad located on the right side of the keyboard
