These devices are often used in legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. 56 VDC class 2 power is delivered to one transceiver, which distributes it to multiple* remote transmitters, and their PoE, PoE+, or High Power PoE cameras*. These transceivers are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power, Ethernet/PoE, and TBus connectivity/activity/quality. They are backed by NVT s award winning customer support and limited lifetime warranty. * Distance and number of devices supported may be lower due to power supply capacity and wire voltage-drop. See Wire Distance Charts on page 4. Aggregate TBus bandwidth is dynamically allocated (shared based on traffic), and decreases with wire distance. See Wire Distance Chart on page 5. Multicast requires an IGMP Querier, either in a network switch, or within the NV-ER1808i or NV-ER1816i Receiver Hub. High bandwidth streaming devices (>15Mbps) that employ unusually chatty protocols (TCP/IP, TFTP, etc.) are not recommended. Use RTP/UDP instead. Page 1 of 5

Wire Type and Power Distance The distance capability of wire is dependant on its ability to deliver DC power, and separately, to deliver highfrequency data signals. The graph below shows maximum power delivery when using a 56V power supply. If you are locally powering your camera (or other remote device), then this graph does not apply. The graph on the next page shows the maximum data delivery rate. A Distance Calculator can be found at www.nvt.com. PoE devices require a minimum of 43V to operate. With a 56V supply, we have up to 13V of allowable voltage drop on the wire. The voltage will dip in proportion to the remote (camera) load. The graph below shows what PoE power distances are supported for various loads and wire types. Start with the camera wattage at the left. Sometimes IP cameras are listed as to their PoE Class rather than wattage. Now read over to the right until you find your kind of wire. Then look up (feet) or down (meters) to find your maximum distance. If your wire is not among the examples, simply measure its total resistance and find the value on the right side of the graph. The maximum supported wattage is on the left.
