Sky terminal connection

1. The serial port of the flight control is cross-connected with the serial port of the module, as shown in the figure: the serial port of the flight control (T1, R1) is cross-connected with the serial port of the module (T, R);

2. The video output interface of the flight control is connected to the video input interface of the module, as shown in the figure: the (VTX) interface of the flight control is connected to the (AV) interface of the module;

Ground terminal connection

1. The module is connected to the VTX diagram and CRSF receiver as shown in the figure;

2. Wired control of the remote control: Use AUX3 section line to connect the PPM interface with the DSC signal interface of the remote control;

3. Video cable connection: The video output cable connection can be used to connect to the display screen or FPV glasses (AUX4 section line);

4. Video wireless connection: connect to VTX transmission, wiring only needs to connect the positive power (VCC), power ground (G), video signal line (AV);

5. Power supply: can be connected to 3S-6S lithium battery (12V-24V);

Switch switching function:

If there is no image, it can be switched by switching the switch

Flight control and ground station setup

1. Install the ground station: Install one of the following two software on the PC first (install according to the software provided by the flight control manufacturer).

https://github.com/betaflight/betaflight-configurator.git

2. Connect the flight control to the PC with a USB cable.

3. Open the corresponding ground station software (BETAFLIG ground station software is used as an example below).

Software configuration

1. Select the COM port of the computer (the port will be automatically recognized), and then click Connect.

2. Follow the following steps, taking the serial port 1 (T1/R1) of the receiving flight control as an example, first click on the port in the software, then open the "Serial digital receiver" of "Serial Port 1 (UART1)", and then click save.

3. Select "Receiver", then select mode as "Serial Receiver (via UART)", protocol as "CRSF", and then save.

4. Fine-tune the joystick of the remote control, and adjust it to the median value of "1500" with the ground station software. Other Settings remain unchanged.

Remote control settings

1. Insert the AUX cable into the DSC interface and the wired control block (PPM-MD).
