The B160-201-HSI 2-Port HDMI Audio/Video with RS-232 Serial and IR Control over IP Extender Kit extends and distributes HDMI audio/video, RS-232 serial and IR (infrared) remote signals through a dedicated Ethernet network switch* located up to 328 feet (100 m) from the transmitter. With an additional 328 feet between the switch and the receiver, the maximum distance from source to display is 656 feet (200 m). You can also directly connect the transmitter and receiver up to 328 feet apart with Cat5/Cat6 cabling. The B160-201-HSI is designed for managed network switches with IGMP, which allow login and remote management via switch interface. You can connect up to 64 transmitters and 255 receivers in a single managed switch installation.** The B160-201-HSI supports video resolutions up to 1920 x 1080 (1080p) at 60 Hz. In a point-to-multipoint switch installation, you can send the HDMI video source to any analog or digital display, including VGA and DisplayPort™.
