Model NV-ER1804 TBus™ Four Port Receiver
Model NV-ER1804 TBus™ Four Port Receiver
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. See manual or IP Distance Calculator at nvt.com.

Number of Ports:
Power is usually supplied from the TBus Receiver. For optional
supplemental local power, an additional Class 2 power supply may be
purchased. These supplies are external inline, with an IEC380-C14
power inlet and 6ft (1.8m) line-cord. Input voltage is 100 ~240VAC
50-60Hz. A molded P1J 5.5mm barrel connector provides Class 2
(SELV) regul ated output with one of these three ratings:

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.
