Nitek EL4500C - Manual (Page 4)

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 Power 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 opera-
tion.
The method for facilitating Ethernet communication and PoE over RG59U cable starts with con-
necting the ER1500C to the Power Sourcing Equipment, usually a switch (RJ45-to-RJ45) via a
CAT5e/CAT6 patch cable. 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 represented below in the “Installment To-
pology - Type A” diagram.
Upon final power up the devices will undergo initialization and auto-configuration processes (see
LED Indicator chart on pg 7) which may take a number of seconds, time variations are device/
installation/topology dependant, to complete before PoE and Ethernet communication commences.
For optimal performance refer to the PoE Distance Chart (see pg 7) and adhering to the IP camera
operational specifications is recommended. If issues arise during the installation process please
see the “Trouble Shooting Tips” section (pg 8). You may also contact our web based live tech sup-

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