Transmitter-end Installation
ET1500C or ET4500C Units
6) At the camera location securely mount the transmitter.
7) Find the coaxial cable from the head-end and make sure it is properly terminated RG59 or RG6 (75 ohm type) solid
copper cable. Connect coaxial cable to the BNC jack of the transmitter. If the head-end unit is powered up it will
sense the connection of 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 con-
nected for the transmitter to communicate with the head-end.
8) 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.
