Carrier connection example：

Fix the transmitter on the suitable Station

of drone(by 3M strap), and then

install antenna with vertical down.Next,

camera and transmitter connect with HDMI

cable (or with CVBS cable),and then

connect to power.

Attention：

Please ensure to install the transmitter

antenna and fasten it before POWER ON.

Otherwise, it will damage the transmitter.

Installation example

版本：V2.0（2018.09）第 5页

Receiver connection example:

Connect the HDMI of receiver to LCD display.

And connect the antenna ,fasten it.

Installation notes：

1.Keep the antenna away from metal equipment of UAV, and the antenna should have wide space

within 20cm to other objects to ensure efficient transmission;

2.Make a proper planning about frequency of all wireless equipment on UAV. Otherwise it will cause

the equipment to be unable to use normally.

Usage

S1 pro achieves long distance HD video transmission, suitable for high-real-time applications in

point-to point transmittion. Please order in specific demand.

Channel setting

The transmitter and receiver are in the same channel by default. After the transmitter and receiver

are installed normally, HD video transmission can be realized.

The steps of channel switching are as follows:

1. The product has three RF channel. Press “SW” on the transmitter, one of the signal indicator

CH1/CH2/CH3lights. Green LED means the current channel is in use.

2. Press “SW” of receiver, the OLED will display current channel and indicate the current signal

strength. As shown on the right, the indicator shows current signal

quality.CH1 express current channel of receiver.
