    COFDM transmitter and receiver ST20NPT

    ST20NPT is a COFDM wireless communication equipment based on military standard. It supports 2.4GHz (2. 402~2. 478 GHz) and suitable for long distance, high code stream and wireless transmitting application. The transmitting rate up to be 70Mbps and the farthest transmission distance is 20km air to ground.

    ST20NPT mini transmitter receiver is a set of real-time image transmission system which is specially designed for working with mini drone aircraft. It converts the real-time signal from the mini camera into RF and send back to ground wirelessly. The returned signal will be received by the accessory receiver and displayed on display screen.

    Precautions

    1. If you use the Futaba remote controller, the controller should be adjusted into the French mode. Adjust the Futaba controller into French mode as following steps:

    Or connect ST10NPT S1 serial port with trainer interface on back side of Futaba by TTL cable. And set the Futaba RF as OFF. Through the S1 port uplink the PPM/SBUS signal.

    2. Before using, please check the power of RX and TX. If the receiver power off, transmitter on board will lose connection.

    3. Adjusting RX antenna inclination can improve the signal strength and image quality.

    4. The camera should be fully charged to ensure normal video output.

    5. ST10NPT support video and duplex data communication. If the video stuck or stopped for more than 10s. It means the radio signal is weakened or the radio channel is narrowed. In this case, the aircraft need to fly back to short the distance between TX and RX. Otherwise the TX will lose connection.

    6. Please use good electromagnetic shielding accessories (such as HD displays, Network cables, etc.

    Notes: Improper operation of ST10NPT may cause personal injury or damage to properties. Please pay high attention to operation safety.
