Meridian’s SR-1RG2A-20 is high performance Video and Audio transmission system that transports fully-compliant DVI, RGsB or RGBHV and two Simplex 24-Bit audio signals over one single-mode fiber. The ST/SR-1RG2A-x product consist of two Meridian’s cards: ST/SR-1RG-xX - 1-ch RGB/DVI Video w/expansion Port, ST/SR-2A-4 - 2-ch 24-Bit Audio connected trough expansion port in order to combine CWDM 1310nm Band and 1550nm Band wavelengths on one single-mode fiber. This product provides real-time, digitized transmission of DVI, RGB and Hand V sync signals. Because it transmits signals in real-time, no video information is lost and is a perfect solution for dynamic video signals with crystal clear video and no color pixel skewing. Having both DVI and RGB input capability, this system offers an easy upgrade path from RGB to DVI systems with the same modules. In addition, this dual format capability allows the user to convert from one format to the other (RGB to DVI, DVI to RGB) to ensure compatibility with a wide variety of video sources and monitors. An example of this would be to supply a RGB signal at one end of the link and output a DVI signal at the other end. The supplied adapters (dongles) allow easy interface to standard RGBHV connectors on computers and monitors.The user can further enhance the video performance with the use of the computer USB interface. This data channel allows the user to adjust brightness, contrast, H and V position, picture sharpness, color, check temperature of the card and load voltage.
