Nitek ER8500C - Manual (Page 6)

At the camera location securely mount the transmitter.
Find the coaxial cable from the head-end and make sure it is properly terminated RG59 or RG6 (75 ohm type) solid copper ca-
ble. Connect coaxial cable to the BNC jack of the transmitter. If the head-end unit is powered up it will sense the connection to
the transmitter unit and turn on the power. This will be indicated by the green POWER LED on the “Network Port”. After about 15
to 30 seconds the green 10/100 (upper) LED at the “Coax Port” will turn-on to tell you that the head-end has connected with the
transmitter unit. The Ethernet device does not need to be connected for the transmitter to communicate with the head-end.
Finally, connect an Ethernet device to the transmitter “Network Port”. If the device requires PoE power, the POE OUT (lower)
LED at the “Coax Port” will turn on followed by the LINK STATUS LED on the “Network Port”. The IP camera or other Ethernet
device should now be ready to operate. Continue installing the remaining transmitters as needed.
