I'm using the datalogic Lynx D302 model scanner for data barcode verification. The scanner is connected to the PC using the Wedge connection. But now I'm facing a problem whereby the keyboard does not work once the scanner is connected.
What could cause this problem? What I suspect is the Y-cable with the keyboard emulator which could be faulty?
Appreciate if you send advise me on this.

If the scanner is connected through USB connection, the barcode should appear in the Notepad. If you use the Serial connection RS232, the Barcode data are showed than in Hyperterminal or other application, which is interpreting data from Serial Port.
Please scan the barcode from Product Guide according to your connection. And check the scanned data in an application - Notepad for Keyboard Wedge or USB, Hyperterminal for RS232.
I also purchased a Symbol LS4071 and when I connected this scanner (purchased at a great discount through eBay) to my computer using the keyboard wedge (with a ps2 connection - the round connector - the connector is split like a "Y") I received the error message that my computer could not recognize this external hardware. I went to barcodediscount.com and ordered the usb connector for this scanner as usb connections are usually recognized. The part # for this connector is STI85-0200R. It cost 72.55 with shipping, but I received the scanner at such a wonderful price that I thought I'd chance it and try it with a usb rather than a keyboard wedge connector. The computer immediately recognized the usb connection, and the usb connector comes with a manual with codes to enable proper scanning, but still no luck getting the data into the computer. So I called Symbol's technical support department. The technician told me to remove the rubber "boot" at the bottom of the hand held scanner (not the scanner base) by pulling on the front of it (where the 2 little round circles are). It's tough to remove, but keep at it. Then gently remove the battery and unplug it, then plug it back in and reattach the base. He said this would reset the battery. Voila!!!! Sucess!!!!
If your scanner's keyboard wedge connection is recognized (a little popup window will say that it is a Symbol barcode scanner and that it is installed and ready to use), try taking the battery out and putting it back in to reset it. Hopefully this will also work for you. Symbol's technical support # is (800) 722-6234.
If your cables are connected between your keyboard and PC, be sure to set up the correct Keyboard Wedge Parameters, beginning on Page 34, to allow connectivity.
I'd start by scannig barcodes "CE" and "ZA" to reset to default wedge values. If that doesn't work, I'd procede to sc an "CF" for PC=AT,PS/2.
Pages 36 & 37 address the Caps Lock issue, where the scanned value is in the wrong upper or lower case.
You could use a ps2 splitter cable to connect both the barcode scanner and the keyboard to the pc.
You would also have to use the correct scanner codes to ensure that the scanner is configured properly.
Alternatively, you could try connecting the scanner with only the ps2 to usb and miss out the extension cable to determine if that is the problem.
If the scanner is a ps2 wedge scanner, it will need reprogrammed with the correct scanner codes for usb.
