16 Port IP Video Extender Over Single Twisted Pair
With Built-In Gigabit Layer 2 Switch with
The ER1651U is another component of the NITEK cutting edge EtherStretch line. Our EtherStretch solution al-
lows for the utilization of existing twisted pair cable infrastructure to transmit data from IP cameras and other net-
work 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 capa-
bilities. 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 trans-
mitters (up to 16) can quickly turn ordinary Twisted Pairs into a series of high speed network communication path-
ways. 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 retro-
fitting existing installations. The rack mounted unit is robustly constructed of molded steel casing with appropriate
built-in cooling and ventilation.
