Nitek EL4500C - Manual (Page 5)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the EL1500C is rather quick and easy. A
common topology involves a length of existing coax cable up to but not exceeding 1,600ft / 500m, the
EL1500C transmitter and receiver pairs (ET1500C & ER1500C), an IP camera or other peripheral network
device (both universally referred to as the Power Device or PD), and a 3rd party PoE network switch or Pow-
er Sourcing Equipment/PSE. The PD and PSE must both be either 802.3af or 802.3at compliant. That is
requiring or producing no more then15.4 W 48VDC @ 350mA of 802.3af 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 RG59U cable starts with connecting the
ER1500C to the Power Sourcing Equipment, usually a switch (RJ45-to-RJ45) via a CAT5e/CAT6 patch ca-
ble. The ER1500C coax BNC connector enables connectivity to the length of RG59U coax cable at the head
end. The IP camera interfaces with the ET1500C via RJ45 and a CAT5e/CAT6 patch cord. The output of the
ET1500C intern connects to the length of RG59U cable by its BNC connector at the camera end. Power
from the PSE provides operational PoE for both EL1500C units and the camera. An illustration of this is rep-
resented below in the “Installment Topology - Type B” diagram.
Upon final power up the devices will under go initialization and auto-configuration processes (see LED Indi-
cator 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 per-
formance referring to the PoE Distance Chart (see pg 6) and adhering to the IP camera operational specifi-
cations is recommended. If issues arise during the installation process please see the “Trouble Shooting
Tips” section (pg 7). You may also contact our web based live tech support at:

Installment Topology - Type B
Shown in the diagram above, is the EL1500C devices (sold as a packaged pair) consisting of a
transmitter and receiver unit. They are connected to an existing coax cable which enables the
tranmisson of up to 100Mbps of network data. Power for the units as well as for the camera is
dervied from the 3rd party PoE Injector. Total distance, via RG59U cable, between the EL1500C
devices cannot exceed 1,500ft./500m.
