VGAR/T300 twisted-pair VGA transmitter can transmit VGA signals of 0-300m. It is a signal transmission system with the functions of VGA signal conversion, distribution, driving, receiving and restoration, and is specially designed for the requirements of long-distance transmission of high-quality video signals in network flat panel display and large screen curtain wall display advertising engineering, industrial automation control, medical equipment, security monitoring and multimedia teaching. It can transmit VGA signals in a balanced way through unshielded five types of network cables, thus enhancing the suppression of * * * mode noise and interference signals, greatly saving conductor costs and simplifying engineering wiring. Patented technology is used to encode H and V signals onto RGB signals and then transmit them. Only three pairs of five twisted pairs are used to complete the balanced coding and decoding of VGA, SVGA, SXGA, XGA and SXGA RGBHV signals, and long-distance high-frequency compensation weighting processing is adopted, with a bandwidth of up to 350MHz. The receiver adopts the unique multi-stage broadcast video signal processing technology in the industry, such as balanced input signal buffering, ground potential isolation, variable gain amplification, balanced/unbalanced conversion, five-stage pole-weighted balanced compensation, * * mode signal recovery, output gain adjustment, co-channel signal decoding, high-fidelity video distribution, etc. At the same time, it has continuous brightness and contrast control, and the transmission distance reaches 300 meters (1920 * 65438). Because the whole transmission system adopts the patented technology of weighted zero split balanced transmission, twisted pair will not cause EMI interference when transmitting signals. In addition, additional twisted pairs can transmit audio signals.
