Transmitter-end Installation
ET1500U Units
6) At the camera location securely mount the transmitter.
7) Find the Link cable from the head-end and make sure it is properly terminated. Connect Link cable to the “Link Port” of
the transmitter. If the head-end unit is powered up it will sense the connection to the transmitter 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 or-
ange 10/100Mb LED on the “Link Port” will turn-on to tell you that the system is connected. An Ethernet device does
not need to be connected for the transmitter to communicate with the head-end.
8) Finally, connect an Ethernet device to the transmitters “Network Port”. If the device requires PoE power, the POE
OUT, green LED on the “Link 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.
