Data Sheet FRONT BACK Features: Transmit 10/100 BaseT Full Duplex Ethernet up to 2.5km (8,000ft) over R-59/U, 610m (2,000ft) over 2-Wire/UTP, or 396m (1,300ft) over Shielded Twisted-Pair* The TBus architecture allows multipoint operation in any star or daisy-chained topology, with any combination of cable types, and up to 64 remote transmitters/ip cameras Transparently supports all networking protocols (UDP, TCP/IP, HTTP, Multicast etc.) using advanced 128-bit AES encryption Dual 10/100/1000 uplink ethernet connectivity Easy configuration, no PC required 56VDC is distributed over the TBus to all connected equipment. PoE, PoE+, or High Power PoE cameras (or other PoE devices), up to 50 watts* are supported. The NVT Model NV-ER1816i TBus Ethernet over Coax/UTP Receiver Hub is a 1U 19" rack mountable busarchitected media switch that has 16 TBus ports, capable of supporting up to 64 TBus transmitters and their subsequent 10/100 BaseT Ethernet and PoE+ powered devices*. The TBus transmission medium can be coax, 2-wire/UTP, or Shielded Twisted-Pair. Data rates up to 200 Mbps are achievable, making this device the ideal choice in new or legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. An internal 250 watt 56VDC power supply can be optionally augmented by an external 250 watt auxiliary power supply, supporting redundancy and/or higher power applications. The NV-ER1816i is backed by NVT s award winning customer support, limited lifetime warranty, and advance replacement. No IP or MAC addressing configuration is required, yet is available for browser-based monitoring and control. This provides exceptional yet simple configuration and diagnostics for the installer or remote monitoring facility. Status LEDs indicate power, auxiliary power, and link connectivity/activity. *Distance and number of devices supported may lower due to limited power supply capacity and cable voltage-drop, or data-rate limiting due to the selected cable s high-frequency signal attenuation.

Cable Type and Power Distance Capacity The distance capability of cable is dependant on its ability to deliver DC power, and separately, to deliver high-frequency 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 13V of allowable voltage drop on the cable. 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 cable types. Start with the camera wattage at the left. Sometimes IP cameras are listed as to their PoE Class rather than wattage. If this is the case, use the coloured classes instead. Now read over to the right until you find your kind of cable. Then look up (feet) or down (meters) to find your maximum cable distance. If your cable is not among the examples, simply measure its total resistance and find that value on the right side of the graph. The maximum supported wattage is on the left.
