Nitek ET4500C - Manual (Page 4)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the ET4500C is rather quick and easy. A com-
mon topology involves a length of existing coax cable up to 1,640 feet or 500 meters, the ET4500C transmitter and
the associated rack mounted multi-port receiver such as the ER8500C or ER16500C, an IP camera or other periph-
eral 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 56VDC @ 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 a receiver,
via a CAT5e/CAT6 patch cable, to a server or other network switch. The receiver unit BNC coaxial connector port
enables connectivity to the ET4500C four Port Transmitter via . The IP devices interface with the ET4500C via four
Link Ports (RJ45) and CAT5e/CAT6 cables. The link port output of the ET4500C intern connects to the length of
RG59U cable by its BNC connector. Power from the multi-port receiver provides operational PoE for the ET4500C.
An illustration of this is represented below in the “Installment Topology” diagram.
Upon final power up the devices will undergo 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 de-
pendent, to complete before PoE and Ethernet communication commences. For optimal performance referring to
the PoE Distance Chart (see pg 6) 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 7). You may also
