1. Introduction
The NETUM NT-A5 is a high-performance desktop omnidirectional barcode scanner designed for efficient and hands-free scanning of both 1D and 2D barcodes. Featuring an intelligent infrared sensor, it offers automatic standby and wake-up functionality, making it ideal for various applications such as retail, libraries, and pharmacies. This manual provides detailed instructions for setting up, operating, maintaining, and troubleshooting your NT-A5 scanner.
2. Quick Setup Guide
2.1 How to Start
- Connect Scanner: Connect the scanner to your device (laptop, desktop, etc.) via the provided USB cable.
- Setup Keyboard Language: If you are using a US keyboard, the scanner is plug-and-play and no further setup is required for keyboard language. If you use another type of keyboard, you will need to scan a specific command barcode from the full manual to configure the keyboard language.
- Locate Cursor: Place the cursor in the application where you want the scanned data to appear.
Once these steps are completed, you can begin scanning.
2.2 USB Interface (Optional)
The NT-A5 scanner supports two USB interface modes:
- USB HID-KBW (Default): By default, the scanner operates in HID mode as a Keyboard device. This is a plug-and-play setup, and no additional drivers are required.
- USB Serial: If you connect the scanner to a host via USB, the USB COM Port Emulation feature allows the host to receive data as if it were from a serial port. For Microsoft Windows PCs, a driver is required. This driver can be downloaded from the official NETUM website: www.netumscan.com.
2.3 Factory Defaults
To revert all scanner settings to factory defaults, scan the following barcode:

3.1 Programming Code
NETUM barcode scanners are pre-programmed with common terminal and communication settings. To modify these settings, scan the appropriate barcodes found in the full user manual. An asterisk (*) next to an option indicates its default setting.
3.2 Scanning Barcodes
The NT-A5 scanner offers strong decode ability, capable of reading most 1D and 2D barcodes, including those that are damaged or displayed on digital screens.
3.3 Automatic Standby & Wake Up
The scanner features an intelligent infrared sensor that automatically puts the device into standby mode when not in use and wakes it up when a barcode is presented for scanning, enhancing convenience and power efficiency.
3.4 Important Notes for Scanning
- This scanner has a wide scanning range. To ensure accurate scanning, cover any barcodes close to the one you intend to scan to prevent accidental reads.
4. Maintenance
- Cleaning: Regularly clean the scanner's window with a soft, dry cloth to ensure optimal scanning performance.
- Durability: The NT-A5 features an anti-shock design, remaining functional after multiple drops from a height of 1.5 meters.
5. Troubleshooting (FAQ)
- Q: Is there any barcode to apply or remove a suffix?
- A: Yes, you can visit our official website www.netumscan.com to download the complete manual and refer to the section on "prefix and suffix," or contact customer service for assistance.
- Q: How to solve the messy code problem encountered while using other foreign languages?
- A: The default keyboard language is English. If you are using other keyboard types, please refer to the "Keyboard language" section in the full manual to configure the correct language setting.
- Q: Some barcodes cannot be read. Why?
-
- Dirty or Unclear Barcodes: Barcodes that are dirty, smudged, or unclear might not be read. Ensure barcodes are clean and clearly printed.
- Disabled Barcode Types: Settings for certain less commonly used barcode types might be disabled by default. You may need to activate a specific barcode type to enable scanning. Please contact customer support for guidance.
- Low Voltage: If the scanner beeps twice, it indicates a low voltage state. Charge the scanner immediately for 2-3 hours. The scanner cannot read barcodes when in a low voltage condition.
- DataMatrix GS1 Group Separator: If the 2D scanner cannot output the group separator for DataMatrix GS1, please contact our service team for support. They can provide a command barcode to activate this function.
