The B140-101 is a DVI over Cat5 Passive Extender kit, which comes with both transmitter and receiver units. It transmits a DVI-D Single-Link signal up to 100 ft. away using a single Cat5e/6 patch cable. To achieve maximum distance and resolution, use 24AWG Solid Wire Cat5e/6 cable (Tripp Lite's N202-Series). The B140-101 is compatible with all operating systems, and is plug and play, with no external power, software or drivers required
