Arayüz tanımlayın

Güç girişi arayüzü (Güç), AV output interface (NIN-NİN)

The power input interface is a 2PIN 2.0mm pitch socket that supports a DC voltage of 7~24V. AV çıkış konektörü 4PIN 2,0 mm aralıklı bir sokettir. Güç giriş arayüzünün ve AV çıkış arayüzünün sinyal tanımları aşağıdaki gibidir:

Veri UART'ı, UART'ı yapılandır, Mikrofon Girişi ( Mikrofon girişi)

Data UART, bir dizi TTL seri bağlantı noktasına sahip 3PIN 1,25 mm aralıklı bir sokettir. Config UART, bir dizi TTL seri bağlantı noktası içeren ve 5V harici güç kaynağı sinyalleri sağlayan 4PIN 1,25 mm aralıklı bir sokettir.. Mikrofon girişi 2PIN 2,0 mm aralıklı bir sokettir. Veri seri portunun sinyal tanımları (Veri UART'ı), yapılandırılabilir seri bağlantı noktası (UART'ı yapılandır), ve mikrofon giriş arayüzü (mikrofon girişi) aşağıdaki şekilde gösterilmiştir.

Ethernet arayüzü (ethernet)

Ethernet arayüzü 4PIN 2,0 mm aralıklı soketi veya doğrudan lehim deliğini benimser. Sinyal tanımı aşağıdaki şekilde gösterilmektedir. This Encode board can output the demodulated video stream of the DR2C COFDM wireless receiving module to the PC or NVR device through the Ethernet interface for decoding and playback. This Encode board can also input video streams through the network port for low-latency decoding playback. For different applications of the Ethernet port, you may need to program different Decode Board firmware. Eğer ihtiyacın varsa, lütfen bizimle iletişime geçin.

LED lights and buttons

Var 3 LED lights onboard, and each LED light is defined as follows:

Signal name	Açıklama	Not
Power-LED	Power input indicator	Red Light
Link-LED	Wireless link status indicator (lights up after system startup, blinking during normal operation of the wireless link)	Green Light
REC-LED	Record video indicator (always on when recording video)	Green Light

 

The Key2 button is a video recording on/off button (Record button), and long-press the button to switch the state. After this Decode Board detects the storage device, it starts recording and preferentially records to the TF card. If the TF card is not inserted, it is recorded to the USB flash drive. If they are not inserted, they will not be recorded. The recorded video file has time information. Yerleşik RTC, system time can be set and saved through the configuration of the serial port.

The Key1 button superimposes the text information on the on/off button (OSD button) displayed on the video screen. When the OSD button status is “Kapalı”, text information is not superimposed on the video screen. When the OSD button status is “On”, text information is superimposed on the video screen. Press and hold the OSD button to switch the switch state, and the switch state will be powered off. When the SHD5 board is shipped, the OSD display function is disabled by default. If you need to open the OSD display function, please use this button to switch the OSD display status.

 

When the OSD display status is turned on, it will be displayed in red in the upper left corner of the output video screen:

RF: 338.0MHz BW: 4.0MHz; RF indicates the center operating frequency, BW indicates the working bandwidth

QPSK CR: 2/3 GI: 1/16; QPSK is the modulation mode, CR is the convolutional code rate, and GI is the guard interval.

HAVA: 3.90MbpS; AIR is the air interface rate

VBR: 3.05Mbps AES OFF; VBR is the video bit rate, AES OFF means no encryption

S1:27 S2:22; S1 refers to the signal strength received near the HDMI port antenna, and S2 refers to the other antenna.

B1: 0.14% B2: 100.00%; B1 refers to the BER error rate near the HDMI port antenna, and B2 refers to the other antenna.

REC OFF No Storage; REC OFF means no video storage

 

When the wireless receiving signal is interrupted, the output video screen will be interrupted (the re-received signal screen will be automatically restored), and it will display:

This decode board can be flexibly used with other COFDM Wireless Video receiver modules. This decode board can be separately assembled with the DR2C COFDM receiving and demodulating module and the RCD two-way wireless link module to form a wireless receiver with different functions, and realize wireless signal receiving demodulation and audio and video decoding output.
