QPSK HDMI AV COFDM Wireless Hd Transmitter With Serial Port RS232
UAV Video Transmission installation directions:
1.Use velcro or ribbon to fix the transmitter on the drone,as shown
above.(The installation location is best close to the aircraft's
center of gravity position,the vibration is relatively small)
2.You can fix the antenna on the UAV two tripod, keep the antenna
3.HDMI cable to connect the camera's HDMI output and the
transmitter's HDMI-In interface.
- Please confirm the velcro or ribbon to ensure that the transmitter
- The transmitter and the PTZ camera please try to choose appropriate
location to install,Use the appropriate length of HDMI cable as
much as possible to reduce electromagnetic interference.
- When installing the transmitter, please note that the interfaces
(such as power supply interface, HDMI / AV source input interface,
antenna interface) are not blocked, so that easy to use a variety
of line connections.
- Please make sure the transmitter cooling hole is upward and
- The device is not waterproof, not oilproof.
UAV Video Transmission Interface Introdution:
Transmitter Antenna:SMA Female head,Standard with omni directional feeder whip
antenna,antenna gain is 3.5dbi.
(Note: Please don’t turn on the transmitter without TX antenna
,otherwise it cound be damaged.)
FM board Interface:From left to right the pins are:1.DC5V,2.GND,3.RXD,4.TXD, If
needed, transmitter parameters can be modified by our FM board or
through the computer serial port.
Data interface: Can be connected with computer,change parameters via serial port
TTL level,Transparent baud rate factory default is 115200, Please
confirm the details in our instruction list.
Power Interface: voltage12V DC, current 1A
A/V CVBS Signals Input: 3.5MM / 3 audio and video interface, AV cable connect to the
Working Indicator:Work indicator are red and yellow digital tubes,normal work power
on with red indicator,Connected to the signal source,yellow light
blinks when the transmitter normally sends data,The faster the
flash, the larger the transmitted data.
HDMI signal input:HDMI-C interface, you can use the HDMI (C-D) cable to connect
The C654 transmitter is a mini COFDM video transmitter from
Wireless LinkAV, designed specifically for UAV/ Drones video
With proven LinkAV COFDM technology and H.264 encoder technology at
its core, the C654 transmitter enables viewers high definition
images ideal for establishing rugged wireless video links in all
environments including mobile and urban environments.
The small size and ultra-low power consumption make the C654
transmitter ideal for UAV installations, enabling true long range
HD quality transmission from these increasingly popular devices for
the first time. Optional lightweight, low power consumption
amplifiers are also available for even greater range capability.
C654 transmitter can transmit images air to ground up to 20km,
depending on mode and frequency.
