Introduction

The AVL58 includes both Video Link Transmitter (TX) and Video Link Receiver (RX), working in the ISM frequency band of 5.8GHz (5645- 5945MHz MHz). Analogue modulated video signals are sent wirelessly by the TX module to the RX module, and then the video signal will be demodulated and sent to a display. There are 8 wireless channels can be selected when you are using AVL58. These channels are: CH1-5705MHZ, CH2-5685MHZ, CH3-5665MHZ, CH4-5645MHZ, CH5-5885MHZ, CH6-5905MHZ, CH7-5925MHZ, and CH8-5945MHZ.

The characteristics of the AVL58 are: small size, low power consumption and high sensitivity. The AVL58 can be used in many applications requiring wireless video communication. When it’s used in the aero-modeling hobby, the Video Link Transmitter will be mounted to the aircraft and the Video Link Receiver is connected to a display screen, allowing video signal wireless transmission.

Important:

 The antenna MUST be connected before power on, otherwise electronics damage may occur.  When use a battery to supply power for the RX and the display screen, the battery voltage must

not be higher than the input voltage of the display screen; otherwise damage may occur to your display screen.

 Ensure there is no obstacle between antennas; otherwise the communication range will be reduced.
