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 bus-

architected 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 lega-

cy 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. See manual or IP Distance Calculator at nvt.com.

Model NV-ER1804 TBus™ Four Port Receiver 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.
