The HDMI/RS232 over IP Extender Kit with PoE allows HDMI equipment to be connected up to 330ft (100m) at 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 Transmitters and Receivers to the same Ethernet network. The Transmitter (500753-TX) and Receiver (500753-RX) also support PoE (PD) if used with a PoE (PSE) Ethernet Switch. The kit comes with one (1) Transmitter and one (1) Receiver. The IR Emitter and IR Sensor, if required, may be purchased separately 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. MuxLab recommends using the Cisco SG300 series managed switches.
