9. Due to the Automatic Gain Control, the camera
image may take a few seconds to stabilize. This is
normal. The LongReach II Hub 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 LongReach II Hub 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
LongReach II Hub exceeds +/-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
LongReach II Hub will function normally and there
is no need to take corrective action.
