Wireless Barcode Scanners are indispensable whenever a person needs to collect data away from a PC. Mobility makes just about all the difference for ease of input, and many times you'll find that extending the cord of the existing barcode scanner isn't possible or practical. Only wireless barcode scanning will do.
There's a little misunderstandings when most people think of wireless barcode scanners. Occasionally, a program will beg a device that functions exactly like its corded brother, however, you require the range of motion of having the ability to walk away the computer to record the data. Other occasions, you'll want to collect data far away from any PC but then have it moved from the instrument to the PC when you return. Since the scanner is portable, it may be called a wireless barcode scanner. Still another scenario occurs when you want to be independent of a PC however would like to examine and write to a database somewhere on the network. In this situation, the barcode scanner will have a wireless network connection, and the software will be navigating to the data origin to update the data. All of these illustrations can be classified as using wireless barcode scanners.
Before making the decision to go wireless, you've got to decide whether you simply need to lengthen the range from the PC, and you could do the job if you had a longer cord, or you will need a genuinely portable data collection process, with a hand-held mobile computer with a built-in barcode scanner. If your data collection would work by just increasing the cord, a "wireless wedge" scanner will perform the job nicely. These types of scanners are less expensive than their technologically superior and more expensive counterparts.
Wireless Wedge Scanners behave just like corded scanners:
Wireless wedge scanners have 2 elements, the scanner and the base station. The scanner can communicate with the base station, and the base station will send the decoded barcode information into the computer it's linked to. Base stations connect to the computer the same way wired scanners do, utilizing a PS2, USB or RS232 connection. With the former 2 connections, the data is delivered to the keyboard buffer of the PC as ASCII text, and the text looks on screen on the host PC wherever the cursor is pulsating. The computer acts as if you just typed in the text that is incorporated in the barcode label. When you have a program which is utilizing the scanned input without presenting it at the flashing cursor, its most likely utilizing the RS232 interface, and the system is using the information from the scanner and placing it wherever it demands to go.
You'll find 2 types of wireless wedge scanners, and the distinction has to do with how the scanner talks to the base station. They could utilize a frequency hopping algorithm making use of the 14 channels available in the 2.4ghz spectrum for wireless transmission or they can use the Bluetooth protocol. Both of them are comparable in range and performance. The intriguing thing about making use of Bluetooth communication is the fact that, usually, you are able to connect the scanner to any kind of Bluetooth enabled receiver, and the ASCII text will be sent to that device. Employing this connection method, you are able to connect direct to another Bluetooth device and by-pass the base station. Prior to purchasing for that reason, make sure that the scanner has a driver that will enable the host device to communicate. Most of the scanners will work with PocketPC devices.
