Discontinued. Extend four DVI-D video, RS-232, stereo audio, and USB Keyboard-Mouse signals up to 400 feet via CAT5 cabling.

replaced by SDX-XT-4P

The SDX-4P DVI extender is capable of sending quad DVI-D signals up to 400 feet over four conventional and inexpensive CAT5/5e/6 cables. The SDX-4P is superior to older DVI extenders that require a special CAT6 shielded cable to go a short distance. This unit also extends USB keyboard and mouse, audio and RS-232 signals, giving users the ability to control displays or devices remotely.

400 feet of signal extension from the SDX-4P gives system architects and end users the ability to create the audio and video environment that best suits their needs and applications. With support for high resolution monitors, users can get the most out of their displays while getting hundreds of extra feet of flexibility. And thanks to the unit’s quad head functionality, users can operate a truly impressive and productivity-enhancing work space.
