Overview
The EL1551U-P 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-P consists of a transmitter unit (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. Because of the twisted pair cabling limitations, longer runs will not support powering additional equipment besides the far end transmitter itself. In the case of longer runs, or higher power applications, power can be injected at the remote transmitter side as well with an optional PS48 supply, providing full 802.3at power of 25.5W.
No IP or Mac address is required. Simply connect the receiver network port to your PoE switch, and 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.
