TBus 8-Port Ethernet Receiver

The NVT Model NV-ER1808i TBus Ethernet over Coax/UTP Receiver Hub is a 1U 19" rack mountable bus-architected media switch that has eight (8) TBus ports, capable of supporting up to 64 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 this device the ideal choice in new or legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. An internal 125 Watt 56 VDC power supply can be optionally augmented by an external 250 Watt auxiliary power supply, supporting redundancy and/or higher power applications.

NVR-ER1808I features include:

• 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 64 remote transmitters/IP cameras
• Transparently supports all networking protocols (UDP, TCP/IP, HTTP, Multicast etc.) using advanced 128-bit AES encryption
• Dual 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.
