Dual Receiver Transmitter Diversity Board

The wiring between the high-frequency head diversity board and the remote control is shown in the figure below :

Precautions for using the high-frequency head diversity board:

The remote control should be configured as an external tuner mode;

• On the remote control, adjust the serial port baud rate of CRSF to 400K;
• The telemetry rate of the two high-frequency heads should be set to the same, and it is recommended to set them both to 1:64;
• The packet rate of the two high-frequency heads should not be higher than 200Hz
• The power input range of the high-frequency head diversity board is 6-35V; ( the key reference is the voltage input range supported by the high-frequency head, and 2-3S batteries are recommended );

Basic requirements and recommendations for data cables:

• The data line uses telephone lines for communication;
• The telephone line connector adopts double-head 4P4C specification;

• entire line length does not exceed 200m (currently only 200m communication has been tested);
• Try to use oxygen-free copper wire core to ensure that the line resistance is as small as possible and reduce the signal attenuation on the line;

Receiver Diversity Adapter

The connection between the receiver diversity adapter and the FC is show as bellow:

Instrucation for Receiver Diversity Adapter:

• Using the transmitter RF module to binding the receiver. Make sure that RX1 is successfully linked to TX1 and RX2 is successfully linked to TX2 . Do NOTuse the remote controller to binding.
