Cat-X extenders for DVI-D, USB-HID

The IHSE USA vario 474 series of extenders offer long distance transmission of DVI-I, DVI-D, USB-HID, USB 1.0/2.0, analog or digital audio and RS-232 control signals over Cat-X or fiber optic cabling. Engineered for reliability and exceptional ultra high resolution image performance, the 474 series uses IHSE USA’s optimized compression technology to deliver perfect transmission of 24-bit digital video to 2048×1152 @ 60Hz (including 1920×1200 and 1080p video transports). These extenders provide virtually lossless image quality with IHSE’s X-Speed technology and, with the optional dual-head and quad-head versions, workstation clutter is practically eliminated with a single console unit supporting up to four displays.

The units can extend DVI video signals with perfect quality up to 10km over fiber or up to 140m over cat-X cables. Images are displayed without delay, brilliantly clear and in perfect resolution quality. Additionally, the vario series 474 can accept separate USB 1.0/2.0, analog or digital audio and RS-232 data. Audio options for the vario cards include AES/EBU and S/PDIF up to 96kHz. Unit connection options for audio include mini-XLR, RCA or TOSLINK supporting Dolby Digital, DTS and PCM.
