NV-ET1801 TBus® SINGLE PORT PoE+ TRANSMITTER
Description
The NVT Model NV-ET1801 TBus PoE+ Transmitter is a compact bus-architected media converter that delivers 10/100 BaseT Ethernet and PoE+ power via coax, UTP or 2-Wire or Shielded Twisted Pair cable. 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.
Features
• Transmit 10/100/PoE+ BaseT, over Coax 8,000ft* over RG-59U; 2,000ft over 2-Wire/UTP; 1,300ft over Shielded Twisted-Pair* • Use with the NV-ER1804 (4-Port)
• Powers PoE, PoE+, or High Power PoE cameras (or other PoE devices), up to 50 watt • Easy configuration, no PC required
The NV-ET1801 TBus Ethernet Transmitter is backed by NVT’s award winning customer support, Limited Lifetime Warranty and advance replacement.
• Transparently supports all networking protocols (UDP, TCP/IP, HTTP, Multicast etc.)
• Advanced 128-bit AES encrypted transmission and PoE+ power technology
* Distance and number of devices supported may be lower due to power supply capacity and wire voltage-drop. See wire distance chart on page 4. Aggregate TBus bandwidth is dynamically allocated (shared based on traffic), and decreases with wire distance. High bandwidth streaming devices (>15Mbps) that employ unusually “chatty” protocols (TCP/IP, TFTP, etc.) are not recommended. Use RTP/UDP instead.
• Built-in transient protection; industrial temperature range • Limited lifetime warranty

POWER SUPPLY Power is usually supplied by 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 a 6ft (1.18m) line cord. Input voltage is 100~240VAC 50/60Hz. A molded P1J 5.5mm barrel connector provides a class 2 (SELV) regulated output.

NV-ET1801 POWER DATA DISTANCE
Datasheet ● Start with the camera wattage at the left. Sometimes IP cameras are listed as to their PoE Class rather than wattage.
The distance capability of wire is dependant on its ability to deliver DC power, and separately, to deliver high-frequency data signals.
● 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.
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.
● 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.
A Distance Calculator can be found at www.nvt.com.
● There are a wide variety of wire qualities, from copper-plated steel at the low end (CATV wire) to high performance low-loss pure copper.
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.
