Although both are used for scanning barcodes, barcode scanners and barcode data collection terminals are totally different types of hardware used for similar but different tasks.
Barcode scanners are typically used for scanning bar codes at a point of sale terminal such as when a customer is purchasing a number of items and going through check out. The clerk takes the item being purchased, and using a barcode scanner scans the items bar code.
When this happens, the barcode scanner sends a signal to the computer with the sequence of numbers that was scanned in the bar code. The POS software then takes that data and uses it to generate an invoice, check out the customer etc.
In a way, a bar code scanner is very similar to a keyboard. Much the same way your keyboard sends a signal to the computer every time you hit a key on the keyboard, the bar code scanner does the same thing. A barcode scanner is an input device that simply scans a barcode, translates the scanned series of bars into a number sequence and then sends that information to the computer it is connected to.
Even though barcode scanners can be mounted permanently, or be hand held wired, or even wireless, they all function in a similar way simply sending the information that they scan directly to the computer. In a way they are “brainless” devices which simply take information, and send it to the computer for processing. It is up to the POS software on the computer to make sense of the numbers that are being sent to it from the scanner.
Barcode data collection terminals, on the other hand work differently. They are more similar to computers themselves. They may look similar to a bar code scanner, but they work differently. Barcode data collection terminals typically have a software platform installed on them which in some way not only collects the data, but also does basic processing functions.
For example, while doing inventory count you may scan an item with a data collection terminal and then the terminal will prompt you to enter in the quantity of items that this item has on the shelf. In this way you can simply enter in the quantity of items without having to scan every item on the shelf. The data collection unit then remembers this information in its internal memory database and allows you to move onto the next item.
The software on barcode data collection terminals can be programmed to work in many different ways with different levels of sophistication. Once the data is collected, the terminal is connected to a computer where a download takes place of all the data at once. In this way, you could scan dozens, hundreds, even thousands of bar codes at once and store them in the terminal before downloading to the computer.

The Symbol LS2208 scanner is a very popular, lightweight, ergonomically designed barcode scanner used in conjunction with many Point of Sale (POS) software. However, prior to using the scanner with POS software there may be some very simple programming steps that will need to be take to get the scanner ready for operation.
One of the first steps to programming a Symbol Scanner is to program the type of interface that you will be using with the scanner. If you are using USB or Keyboard Wedge interfaces, you don’t need to worry about programming the scanner as the scanners come pre-programmed to use these interfaces.
If you are going to be using the RS-232 or the IBM 46XX interfaces there is a very simple step you must follow to program the Scanner. In the LS2208 Quick Start Guide, under STEP 3 you will have to scan the appropriate barcode for either an OPOS/JPOS or a Standard RS-232 interface. Simply by pointing the scanner at the appropriate barcode and scanning it, you will be programming the scanner to use that interface. The Quick Start Guide also has barcodes you can scan for the PORT 5B or PORT 9B – IBM 46XX interfaces or to switch back to USB or Keyboard Wedge mode.
Once you have the interface programmed, the next thing you will need to program is the enter key, carriage return/line feed function. This function programs the scanner to append a carriage return/line feed character to be sent to the computer at the end of each barcode that is scanned. This will eliminate the need for your cashiers to have to hit enter after scanning a barcode in their POS system.
To program the enter key, carriage return/line feed functionality into the scanner all you need to do is simply scan the three barcodes found in the Quick Start Guide. There is also the option of appending a tab key to the end of a barcode scan in the manual as well, and is performed the exact same way as programming the enter key.
