The barcode scanner terminator setting is critical to ensuring the accuracy and integrity of the scanned data. The terminator setting allows the device to send a specific character or character combination after reading the barcode data to indicate the end of the data. The following is a clear explanation of the barcode scanner terminator setting:

1. The role of the terminator

Identifies the end of the barcode data and ensures the integrity of the data.

It helps data processing software or systems accurately identify the boundaries of barcode data.

2. Common terminator settings

Carriage return (CR): ASCII code is 0D, usually used in command lines or text editors to indicate a line break or the start of a new line.

Line feed (LF): ASCII code is 0A, in Windows systems, it is usually used with carriage return (CR+LF) to indicate the start of a new line.

Carriage return + line feed (CR+LF): ASCII code is 0D 0A, in some systems, this combination is used as a standard line terminator.

No terminator (None): In some cases, a specific terminator may not be required, and you can choose not to add a terminator.

3. How to set the terminator

Scan a specific barcode: Many barcode scanners support configuring the terminator by scanning a specific setup barcode. These barcodes are usually provided by the device manufacturer and contain the corresponding instructions to change the terminator settings.

Use the device setup menu: Some advanced barcode scanners have a user interface or setup menu that allows the user to directly enter or select the desired terminator.

4. Setup steps (example)

Find the setup menu: According to the device's operating guide, find and enter the device's setup menu.

Navigate to the terminator setting options: In the setup menu, find the options related to the terminator settings.

Select or enter the terminator: Select the appropriate terminator (such as CR, LF, CR+LF, or None) as needed, or in some devices, you can directly enter the desired ASCII code.

Save and test: Save the settings and test to ensure that the scanning device correctly sends the selected terminator.

5. Notes

Before setting the terminator, make sure you understand the requirements of the target system or software to ensure that the scanned data is correctly parsed and processed.

If you are not sure how to set the terminator, consult the device's user manual or contact the manufacturer for assistance.
