The LongReach 16 is available in a UTP/Coax version (500122, 500123)

1. Perform steps 1 to 3 listed in the previous section.
2. Ensure that the power is turned off on DVR or mux.
3. Connect one coax cable from each LongReach 16 port to each video input
port on the rear of the DVR.

4. Connect the floating 24VAC power transformer to the hub and plug the
power supply into an AC power outlet. If power is present, then the green
power LED will be ON.
5. Power on the CCTV cameras and DVR. When a video signal is detected,
the green LED on each hub port will be ON.
6. Due to the Automatic Gain Control of the LongReach 16, the camera
images may take a few seconds to stabilize. This is normal. The
LongReach 16 automatically adjusts the brightness, sharpness and color to
compensate for effects due to the cabling conditions. Use the adjustments
on the CCTV camera, DVR or monitor to fine tune the final picture.
7. If there is visible low frequency background noise (wood grain pattern) in
the picture, connect the ground lug of the LongReach 16 to a true building
ground.
8. The following diagram shows the final configuration.
