3.3 Connecting to a Device

Figure 4: Wireless Connection Setup
The JRHC S-7103L scanner supports both wireless and wired connections.
- Wireless Mode: Insert the USB receiver (integrated into the charging base) into an available USB port on your computer. The scanner will automatically connect. No additional drivers are required for Windows, Mac, or Linux operating systems.
- Wired Mode: Connect the scanner directly to your computer using the USB data cable. The scanner will function as a wired device.
4. Operating Modes
The JRHC S-7103L offers three primary operating modes: Wireless, Collect, and Inventory. These modes can be selected via the scanner's menu on the 2.2-inch HD screen.

Figure 5: Three Types of Scan Modes
4.1 Wireless Mode
In Wireless Mode, scanned barcode data is synchronously uploaded directly to your connected device in real-time. This mode is ideal for immediate data entry into applications such as spreadsheets or word processors. The scanner's screen will display the current wireless channel, signal strength, and battery level.
4.2 Collect Mode
Collect Mode allows you to store scanned barcodes internally within the scanner's memory. You can view the barcode content, type, and length on the screen. Data can be exported to your device at a later time. This mode includes a unique barcode feature: press the F2 key to toggle between allowing repeated scans or only unique barcodes. This is particularly useful for tracking serial numbers or inventory items that should only be scanned once.
4.3 Inventory Mode
Inventory Mode is designed for warehouse management and stock-taking tasks. It stores scanned barcodes along with quantity information. Users can check the number, length, and quantity of items on the screen before exporting the data to their device.
