Features: Transmit 10/100 BaseT Full Duplex Ethernet up to 8,000ft over RG-59/U, 2,000ft over 2-Wire/UTP, or 1,300ft over Shielded Twisted Pair* The TBus architecture allows multipoint operation in any star or daisy-chained topology, with any combination of wire types and up to 16 remote transmitters/ip cameras Transparently supports all networking protocols (UDP, TCP/IP, HTTP, Multicast, etc.) using advanced 128-bit AES encryption 10/100/1000 uplink Ethernet connectivity Easy configuration, no PC required 56 VDC 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 Built-in transient protection; Industrial temperature range The NVT Model NV-ER1804 TBus Ethernet over Coax/UTP Receiver is a compact busarchitected receiver hub that has four TBus ports, each capable of supporting multiple 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 these devices the ideal choice in new or legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. 56 VDC is provided by a local power supply. These transmitters are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power and link connectivity/quality/activity for RJ45 and Tbus ports. The NV-ER1804 is backed by NVT s award winning customer support, limited lifetime warranty, and advance replacement. *Distance and number of devices supported may lower due to limited power supply capacity and wire voltage-drop, or data-rate limiting due to the selected wire s high-frequency signal attenuation.

Wire Type and Power Distance Capacity The distance capability of wire 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 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. If this is the case, use the colored classes instead. Now read over to the right until you find your kind of wire. Then look up (feet) or down (meters) to find your maximum wire distance. If your wire 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. 50 W 40 W 30 W 25 W 20 W 18 W 15 W 12 W 10 W 8.0 W 6.0 W 5.0 W 4.0 W 3.0 W 2.5 W 2.0 W 98 ft 197 ft 164 ft 131 ft PoE Cla s 262 ft 984 ft 820 ft 656 ft 590 ft 492 ft 397 ft 328 ft 5 RG59/U 22 AWG RG59/U 23 AWG CATV 20 AWG 2-Wire 24 AWG 2 A G 2-Wire 2-Wire 2 AWG 4-pair Cat5 or 2-Wire 18 AWG 20 AWG W C T C W CATV 22 AWG V 2 AWG A 1,312 ft 1,968 ft 1,640 ft 2,624 ft RG59/U 20 AWG RG6 6,560 ft 5,904 ft 4,920 ft 3,936 ft 3,280 ft 18 AWG RG11 G 1 9,840 ft 8,200 ft 14 AWG AW 13,120 ft 19,680 ft 16,400 ft 26,240 ft 32,800 ft 3 Ω 4 Ω 6 Ω 7 Ω 9 Ω 11 Ω 12 Ω 14 Ω 16 Ω 19 Ω 21 Ω 23 Ω 24 Ω 28 Ω 0 W 38 Ω 10,000 m 8,000 m 6,000 m 5,000 m 4,000 m 3,000 m 2,500 m 2,000 m 1,800 m 1,500 m 1,200 m 1,000 m 800 m 600 m 500 m 400 m 300 m 250 m 200 m 180 m 150 m 120 m 100 m 80 m 60 m 50 m 40 m 30 m Page 4 of 5
