ER1651U

16 Port IP Video Extender Over Single Twisted Pair

With Built-In Gigabit Layer 2 Switch with EtherStretch

Description

The ER1651U is another component of the NITEK cutting edge EtherStretch line. Our EtherStretch solution al­lows for the utilization of existing twisted pair cable infrastructure to transmit data from IP cameras and other net­work devices over the given copper media well beyond the 100 meter or 328 feet networking distance limitation.

The ER1651U is a Ethernet extending rack mounted sixteen port receiver unit with built-in Gigabit switching capa­bilities. The unit requires very little installation time and absolutely no set up or configuration. Independently the
ER1651U will work as a fully functional Layer 2 switch. Additionally, the ER1651U and associated ET1551U trans­mitters (up to 16) can quickly turn ordinary Twisted Pairs into a series of high speed network communication path­ways. When used with remotely powered ET1551U transmitters, the system will allow for cable runs of up to
500m/1600ft supplying both a network connection and PoE power.

The ER1651U is completely transparent to the network thus requiring no IP or MAC addressing. Simply connect
your network devices to the transmitter network port along with the existing cables to the receiver and the system
quickly begins communicating. LED indicators show the status and data speed of network communications along
with Power and Trouble confirmation.

NITEK EtherStretch ER1651U reliably extends network communications to overcome cable distance limitations
offering connectivity to devices in locations traditional networking does not allow. The ER1651U is ideal for retro­fitting existing installations. The rack mounted unit is robustly constructed of molded steel casing with appropriate
built-in cooling and ventilation.

Installation Considerations

Wire and Cable Recommendations: The ER1651U is designed for use with up to sixteen (16) Pairs

of Twisted Wire, compatible with all Category cabling (Cat3, Cat5, Cat5e and Cat6). The quality of
which must be consistent with any reasonably serviceable cable condition. That is 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 plea se
call Tech Support at 1-[phone] USA or (847)259-8 900 (outside US).

Ethernet & PoE: The ER1651U is designed to receive up to 100Mbps (per transmitter) of Ethernet
data and transmit up to 1 Gigabit of aggregate LAN traffic. Additionally, the ER1651U provides per
port sourcing power to operate the transmitter (ET1551U). The transmitter, using the optional power
input can support both 15.4W (802.3af) and 25.5W (802.3at) power schemes at 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 length is indeterminate at the time of installation,
we recommend the use of a time domain reflectometer (TDR) or other method to determine length of
unknown cable distance estimates.

Mounting

Ears

The ER1651U is to be rack mounted. Use the included mounting ears when rack mounting the unit, and be sure to
follow these guide lines.

a. Operating Ambient - Do not install the unit in an assembly where the ambient temperature could exceed
52°C (125°F). NOTE: the ambient temperature in a closed or multi-unit rack assembly could greatly exceed
the ambient temperature outside that assembly.
b. Air-Flow – Leave space on the front of the unit for airflow into the cooling fans and some space on top of the
unit for air to exit the unit. Adequate air flow is required for safe operation.
c. Mechanical Loading – The mounting ears were designed for two ears to support one unit. Other
configurations, such as mounting other equipment directly on top of the unit or using only one mounting ear,
could cause a hazardous condition due to uneven or excessive mechanical loading.

NOTE: Use all four mounting screws to properly secure the unit to the rack.
