The NVT Model NV-ET1804 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.

The NV-ET1804 TBus Ethernet Transmitter 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.

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:

One TBus system may not have more than two
power supplies (including those within a
Receiver Hub). Use only the power cord
