The Gateway receives the scanned barcode data from the HandScanner via BLE. This barcode data is transmitted to the end device via USB cable. In the USB HID mode, the Gateway simulates a computer keyboard. A serial connection is emulated in the USB CDC mode. Also multipairing is possible. The Gateway can be connected with up to 5 HandScanners simultaneously. See “Connection with USB cable in USB CDC mode” on page 10.
