The HDMI/RS232 over IP Extender Kit with PoE allows HDMI equipment to be connected up to 330 feet (100m) @ 1080p via one (1) Cat5e/6 unshielded twisted pair cable in a point-to-point configuration. Point-to-multipoint and multipoint-to-multipoint is possible by connecting several encoders and decoders to the same Ethernet network. The Encoder (500753-TX) and Decoder (500753-RX) also support PoE (PD) if used with a PoE Ethernet Switch. The kit comes with one (1) Encoder and one (1) Decoder as well as an IR Emitter and IR Sensor for remote control applications. For the point-to-multipoint and multipoint-to-multipoint configuration the Ethernet switch must have Gigabit ports, DHCP Server capability and IGMP communications protocol. We recommend using the Cisco SG300 Series Managed Switches. A MuxLab Management Software is available to simplify the configuration and utilization of the 500753.
