OPERATING THE UNITS
Once the connections have been made and power applied, there is little in the way of
operational adjustments required however, all Receivers have Equalization and Gain
adjustments which may be adjusted to improve the appearance of the video signal.
Normally adjustment is not required on shorter cable runs but receivers located at the
end of cable runs near the limit of specified range may need small adjustments of the
Equalization or Gain controls or both.
5.1
Equalization and Gain Adjustments
On all Receiver models, locate the EQ (Equalization) and GAIN adjustments on the side
of the Receiver. The EQ control, is on the left
and the Gain Control is next to it, to the right.
On long c able r uns, th e h igh frequency detail can be lost resulting in a “soft” looking
picture. This will first show up in text where the characters will lose their sharp edges.
Adjust the EQ can sharpen the image.
While viewing an image on a display connected
to the Receiver, insert a small screwdriver into the EQ adjustment on the side panel of
the Receiver. Rotate gently until the best EQ setting, as determined by image clarity, is
achieved.
Then insert the screwdriver into the GAIN adjustment, and rotate gently until the best
Gain setting, as determined by the brightness of the image is achieved.
You may
notice an increase in video noise (sometimes called “snow”) in the picture at higher
gain settings so a compromise will have to be found if the cable run i s at or near the
maximum length.
EQ and GAIN settings are retained by the Receiver.
6.0 TROUBLESHOOTING
Other than faulty or swapped Cat.5/Cat.6 cables or attempting to use the product over
too great a distance, there are seldom problems with these Video Extender products.
If there is no image present at the remote location, connect the display device directly to
the source to make certain that the problem is not in the display. If an image is present
under those circumstances, make certain the transmitter and receiver(s) are receiving
power. Next make certain your Cat.5/5E/6 cable is defect free and the RJ-45 connectors
are securely attached to the cable at both ends.
