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
