How To Operate Handheld Barcode Scanners

Handheld barcode scanners replaced the traditional way of shopping. By just pointing at the barcode print with the laser scanner, you can call up the item and the item's price. Thanks to the invention of handheld barcode scanners, we now have easier and faster shopping.

But, despite our familiarity with the barcode reader, many still don't know how to operate one. For a job or curiosity's sake, let's discuss how a handheld laser scanner works and how it is used to read the barcode label.

A barcode scanner reads the information encoded in a barcode. To do this, it emits laser light to translate the optical reflection from the barcode into electrical impulses. With that information, the computer processes the electrical impulses and finds the corresponding information in its data banks. The handheld barcode scanner works the same as the tabletop scanner we are most familiar with from grocery stores.

Also, operating this device is simple, especially as it is designed for plug-and-play operation. Here are the steps when operating a handheld barcode scanner:

1. Install necessary drivers in the computer for the handheld barcode scanner. One of these applications is the Scanner Configure Manager Software. With this software, you can easily configure the barcode scanner. The computer-scanner communication will also be flawless.
2. Connect the handheld scanner to the hosting computer. The specific steps here will depend on the circuit connection capability of the scanner and the computer. But usually, handheld barcode scanners are connected through either a USB or an RS232 cable. More advanced scanners can be wireless. Simply plug the barcode scanner's wire into the proper port in the hosting computer. If the device is wireless, you just need to connect its wireless hub into the computer.
3. Power up the scanner and the computer. You can use the scanner's serial interface if this has a power connection. If it has no power, you can just connect an AC adapter to use the interface.
4. Configure the handheld barcode scanner. This step should only be done if this will be the first time that the scanner will be used. You need to change some parameters, if needed. Other setup you can arrange includes the beep, device selection, beep delay, wand emulation, keyboard, scanner port, and RS232.
5. Program the various symbols for use by the scanner and the hosting computer. Do this through scanning the bar code called SET ID. Then, scan the two alphanumeric codes and scan the SET ID again.
6. Check if the handheld barcode scanner works properly. Take the scanner's holder and point the symbol scanner at the barcode label. Press the button used in registering information. You'll see the symbol scanner emit its laser at the barcode. See if the information is correct in the computer's monitor or the device's viewer. The handheld barcode scanner is okay if everything works fine. But if not, better do the necessary corrections.
7. Read the handheld barcode scanner manual. You can find all the information you need in this instruction booklet--from the installation to the care tips for the device.

No matter how easy its operation and how complicated its circuit engineering is, the handheld barcode scanner remains one of the most useful products of technology.
