1.2GHz 0.1/25/200/800mW A/V VTX Transmitter VRX Receiver 9CH 1060~1380MHz for Long Rang Drone
VTX Transmitter:
一. Button control and LED light
1. 4 green lights represent frequency：0.1mW（0）/25mW
（D)/200mW(C)/800mW(H), Boot default is 0.1mW. Long press
of the button could switch into next frequency. Cycle the operation，
every long press means the frequency switch and the light on. Note：the frequency needs to be adjusted every time the
power cut off
2. 9 red lights represent band，short press could switch into nextband,
this operation can be cycled. Every short press means the band
switch and the light on. Note：the operation has the setting memory, the system
could save the current band when the power cut off
二. 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 1.2G special customized 'Y' antenna
2.7P1.25 interface arrays：
1).power input DC 7-28V;
2).input ground；
3).video input；
4). 6.5M audio input ；
5).DC output 7-28V;
6).DC output ground；
7_.DC output 5V
