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 10/100BaseT Ethernet and PoE+ powered devices.

The TBus transmission medium can be coax, 2-Wire/UTP, or Shielded twisted-Pair. Data rates up to 150 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.

 

NV-ER1804 features include:

  • Transmits 10/100 BaseT Full Duplex Ethernet up to 8,000.0' (2,438.4m) over RG-59/U, 2,000' (609.6m) over 2-wire/UTP, or 1,300.0' (396.2m) over Shielded Twisted Pair
  • 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.
  • TBus architecture allows multipoint operation in any star or daisy-chained topology, with any combination of wire types, and up to 64 remote transmitters/IP cameras
  • Supports all networking protocols (UDP, TCP/IP, HTTP, Multicast, and more) using advanced 128-bit AES encryption
  • Dual 10/100/1000 uplink Ethernet connectivity
  • Easy configuration, no PC required
  • 56VDC is distributed over the TBus to all connected equipment
