Video Multiplexer System
Model: SD-S803VCS/R
User Manual
1.Brief Introduction
Different from traditional coaxial cable, which only transmit 1 channel video signal ,more signals can be transmitted in one coaxial cable, which saves investment, simplifies construction and achieves better effect; products can realize to transmit video, power, control, audio, broadcast, phone signals and so on, clients can choose available product according to demand. The products are used in new projects and
modification works, which can help to save 80% investment at most according to different environments. (2channels,3 channels,4channels video and control products and relevant ones)
2.Characteristics
1.As project demand, the device is optimized interface, and is convenient for installment with mini volume;
2.Can output 4channels video or 3 channel video +1channel negative RS485 control signal optionally throughelector switch;
3.RS 485 control interface can be driven by special chip with 15Kv anti- static module, which can be 64 nodes;
4.Under HS frequency reuse way, signals are combined with high speed without any delay and disturbances;
5.Adjustable knob is installed in receiver, which can fine adjustment transmision distance, so that get better video effect;
6.Brightness of video signal can be adjusted at the transmitter according to different camera;
7.12V DC power supply, built-in Anti-reverse protection circuit;8.All ports use high quality IVXBNC interfaces;9.Ocular data transmission status with RS485 signal indication; The device has high energy conservation circuit
