    Status LEDs
    The radios have 2 status LEDs, one red and one green. The meaning of the different LED states is:
    Green LED blinking - searching for another radio
    Green LED solid - link is established with another radio
    Red LED flashing - transmitting data
    Red LED solid - in firmware update mode

    Connecting to Pixhawk4
    Use the 4 pin JST-GH connector that should have come with the radio to connect the radio to your Pixhawk4’s “Telem 1” (“Telem 2” can also be used but the default recommendation is “Telem1”).

    Connecting to a PC
    Connecting the radio to your Windows PC is as simple as connecting the micro USB cable (which should have been included with the radio) to your PC. The necessary drivers should be installed automatically and the radio will appear as a new “USB Serial Port” in the Windows Device Manager under Ports (COM & LPT). The Mission Planner’s COM Port selection drop-down should also contain the same new COM port.
