Configuração e conectividade
1. Carregando o scanner
Before initial use, fully charge the scanner using the provided USB charging cable. Connect the small end of the USB cable to the scanner's charging port and the other end to a USB power source (e.g., computer, USB wall adapter). The charging indicator light will show the charging status.
2. Ligar / desligar
To power on the scanner, press and hold the trigger button for a few seconds until you hear a beep and see the indicator light. To power off, press and hold the trigger button again until the indicator light turns off.
3. Opções de conectividade
The NT-R3 scanner offers two primary connectivity methods:
Bluetooth Connection (HID Mode - Keyboard Emulation)
- Certifique-se de que o scanner esteja ligado.
- Scan the "Bluetooth HID Mode" barcode (refer to the Quick Start Guide for specific barcodes).
- No seu dispositivo principal (smartphone, tablet, computador), ative o Bluetooth e procure por dispositivos disponíveis.
- Select "NETUM Barcode Scanner" or a similar name from the list of devices.
- The scanner will beep to confirm successful pairing.
In HID mode, scanned barcodes are input directly as keyboard entries into any active text field.
Bluetooth Connection (SPP Mode - Serial Port Profile)
SPP mode is typically used for applications that require direct data communication with the scanner. This mode requires specific software on the host device to interpret the data. Refer to your application's documentation for SPP setup.
- Certifique-se de que o scanner esteja ligado.
- Scan the "Bluetooth SPP Mode" barcode (refer to the Quick Start Guide).
- Follow the instructions provided by your specific application for connecting to an SPP device.
Conexão sem fio de 2.4 GHz
- Plug the provided 2.4 GHz adapter into a USB port on your computer.
- Certifique-se de que o scanner esteja ligado.
- Scan the "2.4G Wireless Mode" barcode (refer to the Quick Start Guide).
- The scanner will automatically connect to the adapter. A successful connection is indicated by a specific beep or light pattern (refer to the Quick Start Guide for details).
The 2.4 GHz connection offers a wireless range of up to 10 meters (30 feet).
Modos de operação
The NETUM NT-R3 scanner supports two data upload modes:
1. Modo de upload instantâneo
In this mode, scanned barcodes are immediately transmitted to your connected device. This is suitable for real-time data entry.
2. Storage Mode
The scanner can store up to 2000 barcodes in its built-in flash memory. This mode is useful when working out of range of your host device. Barcodes can be uploaded later when a connection is established.
