Frequently Asked Questions - SG20B HONEYWELL
How do I connect the Honeywell SG20B to my computer?
Connect the USB cable to the scanner and a free USB port on your computer. The scanner will be automatically detected as a HID keyboard or virtual COM port depending on configuration. No additional drivers are needed for basic operation.
Can the SG20B read QR codes and other 2D barcodes?
Yes, the SG20B supports a wide range of 2D symbologies including QR Code, Data Matrix, PDF417, and Aztec Code. It also reads all common 1D barcodes.
What do I do if the scanner does not beep or light up?
First, check that the USB connection is secure. Try a different USB port or cable. If using a power adapter, ensure it is plugged in. The scanner may need to be reconfigured by scanning a setup barcode from the manual. If the issue persists, contact support.
How do I clean the scanner lens?
Use a soft, lint-free cloth slightly dampened with water or a mild cleaner. Gently wipe the scan window. Do not use abrasive materials or solvents as they may damage the lens. Avoid spraying liquid directly onto the scanner.
What is the maximum scanning distance?
The scanning range depends on barcode density and type. Typically, it reads from contact up to 15 cm for standard 1D barcodes. High-density codes may require closer proximity. Refer to the manual for specific ranges.
Can I use the SG20B with a tablet or smartphone?
Yes, if your tablet or smartphone supports USB On-The-Go (OTG), you can connect the scanner via an OTG adapter. Some models may require additional configuration. The scanner acts as a keyboard input device.
How do I change the barcode prefix or suffix?
Scan the appropriate configuration barcodes from the user manual to add or remove prefixes and suffixes (e.g., carriage return, tab). This allows you to customize output for your application.
What does the LED status indicator mean?
A solid green LED indicates power and ready status. A green flash confirms a successful scan. A red LED or flashing may indicate an error, low battery (if battery-powered variant), or configuration mode. Refer to the manual for detailed meanings.
Is the SG20B compatible with POS systems?
Yes, the SG20B is widely compatible with POS systems that accept keyboard wedge input. It can also be configured as a virtual COM port for serial communication. Check your POS software settings for USB HID or serial input.
How do I reset the scanner to factory defaults?
Scan the Factory Default barcode located in the user manual. This will restore all settings to original. If you cannot find the barcode, power cycle the scanner while holding the trigger (if applicable) or contact support for instructions.
