Installation & Use

Keyboard Wedge

Keyboard Wedge is the most versatile way to interface your scanner. It works with any operating system (past or future) including all releases of MS Windows, Unix, Linux, DOS... etc. It requires no software drivers because it emulates the keyboard. When you scan a barcode your computer 'thinks' the data is being typed from the keyboard. Keyboard Wedge requires a regular PC with a PS2 keyboard connector.
  1. Switch off power to the computer.
  2. Remove the keyboard from the back of the computer
  3. Inspect the keyboard connector and the connectors on the scanner. The scanner is supplied with two types of connector. If the keyboard connector is bigger than the scanner connector it is likely you have an older style keyboard with 5 pin DIN connectors. Refit the short scanner extension lead so the scanner and keyboard connectors match.
  4. Insert the plug on the scanner lead into the computer socket (where the keyboard was connected).
  5. Connect the keyboard to the free socket on the scanner lead.
  6. Switch the computer on and test the keyboard and scanner. A simple way is to run a text editing program like Notepad. Make sure keystrokes appear on the screen. Scan a barcode. The data from the barcode should appear on the screen just as if they were typed from the keyboard.


USB installation is given for a PC running MS Windows 98SE or later. Other platforms and operating systems may differ and you should refer to your computer documentation regarding the installation of USB devices. Note that Windows 95 and early versions of Windows 98 did not include USB support even though some of these computers had the USB hardware fitted. The USB interface is specially designed to allow 'hot swapping'. This means USB devices may be connected and disconnected while the computer is switched on and running.
  1. Switch your computer on and make sure all applications programs have been closed down.
  2. Connect the scanner to the USB connector (usually) on the back of the computer. Do not attempt to scan any barcodes until after the installation process is complete.
  3. After a second or two your PC will prompt for the driver disk. The USB drivers are part of the Windows operating system and are located on your original Windows installation disk. Follow the on screen instructions.
  4. Installation of the USB driver need only be done once. However you will have to install the driver on each USB socket if your computer has more than one. The next time you fit the scanner a connection will be established automatically.
  5. Test the installation. Start a text editing program like Notepad. First make sure your keyboard is working correctly. Now scan a barcode. The barcode data should appear on the screen just as if they were typed from the keyboard.


Detailed RS232 installation and configuration will be dependent on the applications program and/or the particular hardware platform the scanner is to be used with. Engineers and knowledgeable users who require specific technical information and advice on RS232 matters should contact our support desk direct. Appropriate software drivers will need to be obtained from a third party or else specially written.

Scanning normal barcodes

regular barcode

Barcode scanning is easy and intuitive. Simply point the scanner at the barcode and press the trigger. Move the aiming beam across the barcode. A beep will sound and the beam is switched off automatically.

If the scanner does not react immediately move it closer or further from barcode. The exact distance between the scanner and barcode will vary and is not critical. Typically it will be about 25-50mm (1-2 inches). Make sure the aiming beam covers the entire width of the barcode and is roughly parallel to it.

Scanning 2D barcodes

2D barcode

The scanning technique for two dimentional barcode like PDF417 is slightly different.

Start with the aiming beam just outside and above the barcode symbol. Slowly move the beam downward so it sweeps over the entire barcode symbol. As you do so a 'scratching' sound will be heard. When the whole barcode has been traversed a beep will sound and the beam is switched off automatically.

You may need a couple of attempts until the correct action is learned. The following comments may help.

  • The scanner should be held about 25-50mm (1-2 inches) from the barcode such that the aiming beam is just a little wider than the barcode symbol.
  • The beam is moved across the whole barcode at a speed such that the whole barcode is swept in about 1-2 seconds.
  • You may find it easier to start at the bottom and sweep the barcode with an upward motion. The sweeping direction doesn't matter. Use whichever is easier for you.
  • If the barcode does not read after the first sweep keep the trigger pressed and sweep back again in the opposite direction. The scanner remembers earlier sweeps and will 'fill in' on subsequent sweeps.


The scanner requires no regular maintence other than the occasional cleaning of the scanning window with a soft damp tissue to remove accumulated dust.

IMPORTANT: Never use a solvent on any part of the scanner.
