Modos de funcionamento
The NETUM NT-R3 scanner supports two data upload modes:
1. Modo de subida instantánea
In this mode, scanned barcodes are immediately transmitted to your connected device. This is suitable for real-time data entry.
2. Modo de almacenamento
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.
