The radios have 2 status LEDs, one red and one green.
* Green LED blinking - searching for another radio

* Red LED flashing - transmitting data
* Red LED solid - in firmware update mode
### Connecting to Pixhawk Standard Flight Controller
Use the 6-pin JST-GH connector that comes with the radio to connect the radio to your flight controller's “Telem 1” (“Telem 2” can also be used, but the default recommendation is “Telem1”).
### Connecting to a PC or Ground Station
Connecting the radio to your Windows PC or Ground Station is as simple as connecting the micro/type-C USB cable (both included with the radio) to your PC/Ground Station.
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.
