400-0199-006 2 SPECIAL APPLICATION ABOUT YOUR DA1931CT 2 TECHNICAL SPECIFICATIONS 3 DA1931CT Twisted Pair to Video + Audio Receiver The DA1931CT provides a means of receiving computer video and audio signals over Twisted Pair-type (CAT-5) cable when used together with an ALTINEX Twisted Pair Video Transmitter, such as the DA1930CT. The DA1931CT is compact and easy to use. The DA1931CT is able to receive one of the video sources such as RGBHV, component video, S-Video, or composite video, along with stereo audio transmitted over the Twisted Pair cable from the DA1930CT or equivalent transmitter. The DA1931CT provides both audio and video outputs. The DA1931CT offers a female 15-pin HD output for RGBHV/YPbPr signals, a 4-pin Mini DIN connector for S-Video and an RCA connector for composite video output. A 5-pin terminal block is available for balanced stereo output and a 3.5 mm jack is used for unbalanced stereo output. The unit also offers hardware video equalization for long cable lengths. The video equalization works in conjunction with the equalization on the transmitter for optimal performance. There is also a Signal Detect feature which shows when an input signal is present. The latest generation of Twisted Pair devices uses an innovative, patented technology* developed by ALTINEX. The new signal processing technology allows transmitting and receiving fully equalized computer video signals, stereo, and audio signals over long distances. * US Patent 7,065,190 Specifications are subject to change.
