RNDIS Dial-Up
Supports RNDIS Dial-Up via the USB port on Windows/Linux(including Raspberry Pi)
The DTU can support 150Mbps Downlink Speed And 50Mbps Uplink Speed Ideally. But the actual speed is affected by factors such as network coverage, network congestion, and base station conditions.

- Connect the SIM card and antenna to DTU, and connect the USB interface of the DTU to the computer, power on the DTU.
- Install the USB driver(refer to #Install Driver)
- Open SSCOM and find out the serial port number corresponding to the AT serial port you are using. Then send the following command to query whether the device is registered on the network:
AT+CPSI?
- If the device has successfully registered on the network, then send the AT command to enable USB dial-up to the Internet:
