Nitek ET1500U - Manual (Page 4)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the ET1500U is rather quick and easy. A com-
mon topology involves lengths of existing or new UTP (CAT5e/CAT6) cable up to 2000 feet or 500 meters, the
ET1500U transmitter and the associated rack mounted multi-port receiver such as the ER8500C or ER16500C,
an IP camera or other peripheral network device. The IP camera must be either 802.3af or 802.3at compliant.
That is requiring no more then 15.4 W 48VDC @ 350mA of 802.3af (PoE) or up to 25.5W 60VDC @ 600mA of
802.3at (PoE+) power for proper attached device operation.
The method for facilitating Ethernet communication and PoE over the UTP cable starts by connecting a multi-port
receiver such as the ER8500U or ER16500U to the lengths of CAT5e/CAT6 UTP “Link” cables. The IP camera
interfaces with the ET1500U via its “Network Port” labeled RJ45 with a CAT5e/CAT6 patch cord. The output of
the ET1500Us in turn connects to “Link” cables via the “Link Port” labeled RJ45 connector. Power (PoE) from the
multi-port receiver provide operational PoE for both the ET1500U and the attached the IP camera. An illustration
of this is represented below in the “Installment Topology - Type C” diagram.
Upon final power up the devices will under go initialization and auto-configuration processes (see LED Indicator
chart on pg 6) which may take a number of seconds, time variations are device/installation/topology parameter
dependant, to complete before PoE and Ethernet communication commences. For optimal performance referring
to the PoE/distance chart (see pg 8) and adhering to the IP camera operational specifications is recommended.
