Barcode Scanner Configuration Guide
Most HID keyboard-mode scanners are configured by scanning special configuration barcodes printed in the manufacturer's manual, or by using a vendor configuration utility. This guide covers the settings that most commonly need adjusting.
Configuration methods
Configuration barcodes are special barcodes that, when scanned, change a scanner's internal settings rather than transmitting data to the host. Manufacturers publish sheets of these in the scanner's manual or on their support site, organized by setting (suffix, layout, symbology enable/disable, etc.).
Vendor configuration software is available for most professional scanner lines and lets you change the same settings from a desktop application, then push the configuration to the scanner over USB. This is faster when configuring many scanners identically.
Suffix configuration
Set the suffix to match your workflow: ENTER for single-field scan-and-submit, TAB for multi-field auto-advance, or none if your application handles completion via input timing. See ENTER vs TAB Suffixes for a full breakdown of each option.
Prefix configuration
A prefix is a fixed sequence sent before the payload, occasionally used to route a scan to a specific field in legacy terminal software or to tag scans coming from a particular scanner. Most modern web and POS applications don't need a prefix; leave it disabled unless you have a specific reason to use one.
Keyboard layout / locale
This must match the OS keyboard layout on the machine the scanner is plugged into, not the language of the barcode content. A scanner configured for a US layout connected to a machine set to a French AZERTY layout will produce transposed characters for digits and symbols. Configuration barcode sheets list every supported locale; pick the one matching your OS setting, not your data's origin.
Symbology enable/disable
Most scanners ship with many barcode symbologies enabled by default. Disabling symbologies you don't use reduces the chance of a scanner misreading noise or an unrelated barcode (such as a shipping label) as a different, valid-looking format.
Verifying your configuration
After changing settings, scan a known barcode into the Barcode Input Tester to confirm the value, suffix, and character set are exactly what you expect before deploying the scanner to a production workstation.
