Sinais de E/S:

Power in and USB Host

The power input interface is a 2PIN PH2.54mm connector. The USB host is a 4PIN PH2.0mm connector.

 

The AV out is a 6PIN PH2.0mm connector. The Ethernet port is a PH2.0mm connector, 100Porta Ethernet M. This video decoder board supports UDP TS video stream decoding, Decodificação de cliente RTSP, and also RTSP server forward.

Data-uart and control-uart

Uart de dados: 3PIN Conector PH1.25mm, TTL3.3V. When the video decoder board works paired with our video encoder module and Ethernet linker (sem fio ou fio), the uart data of the encoder module will be transferred to this uart.

Controle UART: 4PIN Conector PH1.25mm, TTL3.3V. This video decoder board system can be set up via this control uart with AT command.

LEDs and Keys

The extension port is designed for assembling keys and LEDs if necessary, it’s a 2.0mm 5*2PIN connector, please view the PCB silk printing for its signals (as the photo above).

LIDERADO	Descrição
LED de energia	Light on when the board is normally powered
Video-LED	Blinks when the video stream is normally received and decoding
Record-LED	Light on when video is being recorded with a USB disk or TF card

OSD_key

OSD key: ligar/desligar o status da exibição do OSD, and long press it to switch(mais de 1s). o status será mantido após a reinicialização. Quando o status do OSD está ativado sem nenhuma entrada de dados OSD do data uart, the system will display video information (taxas de bits de vídeo, etc.) on the video screen. When the OSD status is on with data input from the data uart, the system will display text information of the uart data on the video screen.

Chave de gravação

Record key: botão de mudança para gravação de vídeo, pressione rapidamente para alterar seu status. The system will automatically check the storage device(TF card or USB disk, priority TF card) after power on and start to record video when the storage device is inserted. Basta pressionar o botão para parar ou gravar novamente.

Perguntas frequentes

Q: How can I use the Rec key to record the video?

UMA: After the storage device is connected, the system detects the storage device and automatically records the video.

Q: Can I use the Rec_key pin?

UMA: Connect a button between the REC_Key pin and the GND pin (if there is no button, simulate the button operation by short-circuiting REC_Key and GND), or use the MCU’s gpio to connect the REC_Key pin for control.

Q: Do you have an appropriate box for your video LAN modules?

UMA: Não, se você precisar, we have to make one metal box for you, it has extra cost.
We only provide these two boards to customers as accessories. Customers will install them in their own iron boxes. Customers will also install other boards together, so the shell is made by the customers themselves.

Q: One of them has an FPGA that heats up during operation.

UMA: It is normal for the operating temperature to be high during encoding and decoding. Our boards can pass high and low temperature tests at -40 degrees and 80 graus. Se necessário, you can add your own heat sink, or add a cooling fan to the case. Whether it is very hot or not is also related to the local temperature and working environment. Heat dissipation can also be achieved by using thermal conductive adhesive to stick a small heat sink of appropriate size on larger ICs such as CPU and DDR.
