The NVT Model NV-EC1701U Eo2 Ethernet over 2-wire Transceiver is a compact media converter that allows 10/100 BaseT Ethernet and PoE or PoE+ power to be transmitted using 18/2 or similar. These devices are typically used in legacy installations where existing 18/2 is re-used as part of an upgrade to IP devices. 56VDC class 2 power is delivered to one transceiver, which distributes it to multiple* remote transceivers, and their PoE or PoE+ devices.* These transceivers are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power and link connectivity/activity for RJ45 and 2-wire ports. The NV-EC1701U is backed by NVT Phybridges award winning customer support and limited lifetime warranty. * Distance and number of devices supported may be lower due to power supply capacity and wire voltage-drop.
