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 camera is to be powered directly then
you must move the POE Out jumper to the “OFF” position.
8) Finally, connect an Ethernet device to the transmitter “Network Port”. For POE powered cameras, all connection must
be completed for the camera to power up.
9) If all connections are completed and the camera is properly configured you should now be able to ping the camera
and receive video.

Troubleshooting the System
1) Check the power LED on the receiver front panel.
2) Check that a network switch is connected to the front network port of the receiver unit and that there is a link indica-
tion on your network switch.
3) You must have the transmitter and the camera connected.
With a POE Switch
- The Orange LED on the front of the receiver should be on. If not check your connections in
the system.
Non POE Switch
- The Orange LED on the front of the receiver should be on. If not check the DIP switch on
the back panel of the receiver. Also remember that the Jumper on the transmitter must be
moved to the PoE OFF position. The yellow LED below the rear panel BNC jack will also
be “ON”.
4) Check the green LED on the receiver network port. It should be “Flashing” when data is flowing over that port. This
shows you have a transmitter and camera are connected and data is moving over the port.
