1.2Ghz 1W RF Power Wireless Transmitter and Receiver with 8 Channel FPV Image Transmission
1.2Ghz 1000mW Wireless transmitter and receiver 1.2G Image transmission FPV with 8 Channel
Description:
I: Button Control and LED Indicator
-
The four green lights indicate RF power levels: 0.1mW (0), 25mW (D), 200mW (C), and 1000mW (H). The default setting on boot is 0.1mW. A long press of the button will switch to the next frequency. This operation is cyclical, meaning each long press changes the frequency and illuminates the corresponding light.
Note: Frequency adjustment is required each time the power is cut off.
-
The eight red lights indicate the band. A short press will switch to the next band, and this operation can also be cycled. Each short press changes the band and activates the corresponding light.
Note:the operation has the setting memory, the system could save the current band when the power cut off
II. Interface definition
1. The antenna type is SMA: The antenna head is "external thread + hole", and the antenna rod is "internal thread + needle". It is equipped with a 1.2Ghz special customized "Y" antenna.
2. 7P 1.25 Wiring Interface: Red: 7-36V IN
Black: GND (input ground) Yellow: Video input
White: 6.5M audio input
Green: 7-36V output
Blue: GND (output ground) Purple: 5V output
