Connect 3 HDMI Source Devices to an HDMI Display and Switch Between Them This 4K HDMI switch allows you to connect three HDMI source devices to one port on an HDMI display and switch back and forth between them. For instance, you can connect a Blu-ray player, cable/satellite DVR and video game system to one HDMI port on a monitor, projector or TV. Or you can connect three computers or media centers to an HDMI display for exhibiting digital signage or giving presentations. Hassle-Free Setup of 3 High-Definition Computers, Blu-Ray Players or Other Sources The B119-003-UHD is ideal for home entertainment systems, schools, point-of-sale displays, trade shows and anywhere else digital video is displayed. Connect up to three source devices to the HDMI input ports using HDMI cabling (sold separately), and plug the included external power supply into an AC power source. Another HDMI cable connects the HDMI output port to a monitor, projector or television. A red LED indicates the unit is receiving power, and blue LEDs indicate an HDMI signal is being received. Easy Switching of Audio/Video Source Devices You can switch from one source device to another in one of three ways: the Select button on the unit, the included remote control, or RS-232 serial control. An RS-232 serial port connects a computer via DB9 cable (sold separately).
