EL1551U

Categories: , Tags: ,

IP over 2 wire UTP. Set Includes ET1551UM Mini Transmitter & ER1551 Receiver.

Overview

The EL1551U is another part of Nitek’s cutting-edge EtherStretch line. This environmentally hardened solution provides a means to create a 10/100 Ethernet link over ONE pair Cat3 (or better cabling) for distances up to 300m. Multiple links can share individual pairs in Cat5/6 or similar cabling. Shielded and non-twisted cabling will have reduced distances. Larger gauge conductors will improve power transfer.

The EL1551U consists of a mini transmitter unit (for box mounting adjacent to the camera or other network device), and a receiver unit, for the head end. The receiver will request power from a PoE switch to power the link, or local power can be provided with an optional PS48 power supply.No IP or Mac address is required. Simply connect the receiver network port to your PoE switch, your camera or network device to the transmitter network port, and connect the link ports to your twisted pair. LEDs indicate link speed and status.
