NV-ER1804 NVT TBus 4-Port Ethernet Receiver

The NVT Model NV-ER1804 TBus Four Port Receiver is a compact media converter that allows 10/100 BaseT Ethernet and PoE+ power to be transmitted using virtually any kind of cable. These devices are often used in legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. 56 VDC class 2 power is delivered to one transceiver, which distributes it to multiple* remote transmitters, and their PoE, PoE+, or High Power PoE cameras.
These transceivers are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power, Ethernet/PoE, and TBus connectivity/activity/quality. They are backed by NVT’s award winning customer support and limited lifetime warranty.
