EL1551U

IP Video Camera Over Single Twisted Wire

Ethernet Extender with EtherStretch

Description

The EL1551U is another component of the NITEK EtherStretch line. This Environmentally hard-
ened EtherStretch solution allows for the utilization of existing cable infrastructure (coax or UTP)
to transmit data from IP cameras and other network devices along with PoE power to operate
these networked devices well beyond standard network limitations. The EL1551U can extend
Ethernet to over 460m or 1500ft of single twisted pair wire making the EL1551U is ideal for retrofit-
ting existing installations.

The EL1551U system consists of a transmitter and a receiver unit that require very little installation
time and no set up or configuration. The system quickly turns any ordinary single twisted pair wire
into a high speed network communication for distances up to 460 meters or 1500 ft.

The EL1551U is completely transparent to the network thus requiring no IP or MAC addressing.
Simply connect your network devices to the networking port of the transmitter and receiver units
and use the with existing cabling infrastructure. LED indicators show the status of the network com­munications and PoE power.

The NITEK EtherStretch EL1551U reliably extends network communications and overcomes cable
distance limitations offering connectivity to devices in locations traditional networking does not al­low. The units are constructed of industrial grade RoHS compliant plated aluminum with a corrosion
resistant finish makes them extremely durable.

Installation Considerations

Wire and Cable Recommendations: The EL1551U is designed for use with copper based 24AWG

Twisted Pair (CAT3 or CAT5) cable. Other heavier gage wires are possible but the wire must be a
twisted paired cable. The RJ45 network port pin out schemes shall be in accordance with the 568B
standard. The quality of which must be consistent with any reasonably serviceable cable condition.
Cables should be free from damage as in cuts, breaks, or cracks to the outer covering and insulated
shielding which may compromise the signal conductivity of the cable.

For more specific information regarding wire types, gauges, and proper installation techniques
please call Tech Support at [phone] or [phone].

Ethernet: The EL1551U is designed to transmit and receive up to 100Mbps of Ethernet data to a
maximum distance of 1,600ft / 500m. Before considering this solution be sure that the cable involved
does not exceed the recommended maximum lengths. If the cable distance value is undetermined at
the time of installation, we recommend the use of a Time Domain Reflectometer (TDR) or other
method to determine the unknown cable distance estimates.
