HDMI Ethernet Input COFDM HD Transmitter Module For 4K Video Wireless Transmission
Key Features:
COFDM HD Transmitter Module Picture:
The 4K COFDM HD Transmitter module consists of two modules: COFDM modulator and 4K video encoder. These two modules are connected via 26-pin FPC cable. The COFDM HD transmitter can achieve the highest 4K (3840*2160@30) video input with H265/H264 low-latency encoding.It also supports IP Camera video input and transmits after COFDM modulation.
The interface function description of the COFDM HD transmitter module as follows:
| HDMI in | Standard Type A HDMI connector, capable of supporting up to 4K (3840*2160@30) video input with H265/H264 low-latency encoding. |
| Ethernet | 4 pin PH1.25mm connector,support simultaneous connection of IP camera and HDMI input video for COFDM modulation and transmission together. The parameters of the module can also be configured via the Ethernet port connection to the computer by Web UI.The default IP address is 192.168.0.215. |
| Data Uart | 3PIN PH1.25mm connector,bidirectional transparent data uart,TTL 3.3V level, transmission baud rate and other parameters can be configured. |
| Control Uart | 4PIN PH1.25mm connector, TTL 3.3V level, it can be connected to the host computer or our configuration control board for management of COFDM HD transmitter module. |
| Analog Audio in | 3PIN PH1.25mm connector,capable of connecting analog audio input and video for simultaneous encoding and transmission. Default configuration is HDMI audio input, or it can be configured as HDMI input for video,and this audio input port for analog audio.The audio is encoded as AAC,16-bit, mono, 48 Kbps. Line in/Mic in can be configured via software. |
| Power in | 2PIN PH2.0mm connector,supports reverse connection protection for power input, power input range is 7 to 30V. The maximum power consumption of the COFDM HD transmitter module is 5W. Maximum current is 400mA at 12V. |
| HDMI out | Standard Type A HDMI connector |
| USB | Software upgrade and maintenance use |
| Tx | IPEX connector, COFDM modulation RF output port |
