The B126-4X4 4-port HDMI over CAT5/CAT6 Matrix Splitter Switch works with compatible remote receivers to share one or more HDMI sources between multiple projectors, monitors or televisions. It's ideal for digital signs, trade shows, presentations, retail and other applications where the video sources are located farther than conventional cables allow or that require multiple displays connected to one source. It uses HDMI cable to connect to the sources and Cat5e/6 cable to transmit to the remote monitors (for best results, use 24AWG solid-wire CAT5e/6 cable, such as the N202-Series). Any video source can be routed to any monitor, or you can send the same source to multiple monitors. Switch between inputs via push buttons, RS-232 serial or the included remote control.When used with a B126-1A0 or B126-1A0-WP-1 active remote receiver, the switch can extend a 1080i (60 Hz) signal up to 175' (53.3m) or a 1080p signal (60 Hz) up to 125' (38.1m). With a B126-1P0 or B126-1P0-WP-1 passive remote receiver, it can extend a 1080i (60 Hz) signal up to 75' (22.9m) and a 1080p (60 Hz) signal up to 50' (15.2m) Add up to three B126-110 remote repeaters to each channel to fully extend the signal range or add more displays. In addition to crystal-clear video, the B126-4X4 delivers full, rich stereo. Easy to set up with no software or drivers to install. Mounts to a wall, rack or pole using the included hardware.
