8. Power on the CCTV system. When a video signal is
detected, the AGC Lock LED on the 500124 will
change from OFF to ON.
9. Due to the Automatic Gain Control of the Active
Balun, the camera image may take a few seconds to
stabilize. This is normal. The 500124 automatically
restores the video camera signal to its original
quality, compensating for effects due to the presence
of a UTP cable and electrical noise. Use the
monitor’s standard controls to fine tune the final
picture.
10. Connect the ground wire of the 500124 to a true
building ground in order to help ensure that harmful
transient voltages do not damage the equipment.
11. If there is a severe ground loop problem in which the
voltage differential between the camera and the
500124 e/-50 VDC, image distortions may
appear. To correct the problem, additional ground
loop blocking equipment must be installed or the
voltage differential must be eliminated. If there is no
image distortion, the 500124 will function normally
and there is no need to take corrective action.
