Computer Extension : the CAT5-5000/CAT5-5500 A Fundamental Dual-Display Extension Solution Straightforward Way to Extend a Simple Dual-Display Workstation The CAT5-5000 simply and efficiently extends two analog monitors, a USB-based keyboard/mouse and audio signals hundreds of feet from the computer using CAT5 cables. It comes in two versions: the CAT5-5000 sends video, audio and control signals up to 330-feet from the computer; the CAT5-5500 sends video, audio and control signals even further, up to 450-feet from the computer. Each model uses two CAT5 cables to transmit the signals. Both are designed for those who prefer to operate a dual-display computer workstation in a stable, quiet and secure location far away from the computer. Compatibility Both versions work with all CRT and LCD computer monitors, USB keyboards/mice and audio devices (Mac or PC). How It Works Both versions use a sender and receiver methodology to transmit signals from the computer to the workstation. The sender unit connects to the computer using the cables provided. The receiver unit connects to the two monitors, USB keyboard/mouse and audio devices up to 330-feet (CAT5-5000) or up to 450-feet (CAT5-5500) from the computer. Two CAT5 extension cables, sold separately, connect the sender to the receiver and thus the computer to the extended workstation. Both the sender and the receiver units must be connected to a power supply. When fully powered and operational, the units extend all signals efficiently and reliably.
