Installment Topology

Equipment Requirements & Mounting: The process for installing the ER8400C is rather quick and easy. A com-

mon topology involves up to 8 new or existing coax cables (not exceeding 1600ft / 500m), up to 8 ET1500C trans-

mitters and up to 8 IP cameras or other peripheral network devices. The wall mounted ER8400C, which can be re-

ferred to as the NITEK Power Sourcing Equipment (PSE), is compliant with both 802.3AF and 802.3AT devices.

The method for facilitating Ethernet communication and PoE over a coaxial cable starts with connecting the

ER8400C up to 8 coaxial cables via its BNC jacks. Each of the coaxial cables interface with the IP camera via the

ET1500C transmitter, located at the camera end of the cable. The IP camera establishes connectivity to ET1500C

transmitter via RJ5 jacks and a CAT5e/CAT6 patch cords. The ER8400C powers all attached devices within this

system. The Ethernet data from the camera is transmitted over each individual coaxial cable through the ET1500C

to the wall mounted ER8400C in either the IDF or MDF. The aggregate Ethernet data is transmitted to the LAN port

via a built-in Layer 2 switch of the ER8400C. The Gigabit LAN port to ensure congestion-free throughput. An illus-

tration of this system is shown below in the “Installment Topology” diagram.

Upon power up the devices will undergo initialization and auto-configuration which may take a number of seconds

(time variations are device, installation and topology dependent) to complete before PoE and Ethernet communica-

tion commences. For optimal performance referring to the PoE Distance Chart later in this manual. Also adhering to

the IP camera operational specifications is recommended. If issues arise during the installation process please see

the “Trouble Shooting Tips” section later in this manual. You may also contact our web based live tech support at:
