4.0 OPERATING THE UNITS

The Gain and Equalization controls on the 1381R Receiver should be

adjusted to optimize the video signal for the Cat 5 cable length. Low

Gain and Equalization settings are usually best for shorter cable runs

but receivers located at the end of cable runs near the limit of specified

range may benefit from higher Equalization and/or Gain adjustments.

It is best to make adjustments after permanent source and video

display equipment is installed. EQ and Gain settings are retained by the

Receiver even when power is removed.

4.1 ADJUSTING EQUALIZATION

Locate the EQ (Equalization) and GAIN adjustments on the side of the

1381R Receiver. The EQ control is at the top of the left side, and the

Gain Control is just below it.

Symptoms: On long cable runs, the high frequency detail can be

compromized, which appears as a “soft” or “smeared” picture. The effect

is most evident in text and other hard, high contrast edges.

Adjust the EQ to sharpen the image. While viewing an image on a

display connected to the 1381R Receiver, insert a small screwdriver into

the EQ adjustment on the side panel of the 1381R. Turn the screwdriver

gently until the image is optimal.

4.2 ADJUSTING GAIN

If the image is too dark or too bright, insert the screwdriver into the Gain

adjustment and rotate until the brightness of the image is optimal. When

using long Cat 5 cables, you may notice an increase in video noise

(sometimes called “snow”) in the picture at higher gain settings.
