To get the highest quality video signals from your Cobra CAT 5 Video System, follow the instructions and diagrams below:

NOTE: TURN KNOB SLOWLY DURING ADJUSMENT PROCEDURE. Turning too fast may result in missing the proper EQ setting resulting in picture loss.

Push and hold EQ/Skew Knob in and re-apply power.

1.Display a test pattern consisting of a black box on a white background. Press and hold briefly, and then release the EQ/Skew knob so that the R/G/B LED is flashing white.

2.Turn the EQ/Skew knob clockwise until the shadow next to the black box just disappears. The brightness in the white area should be the same as the white area above and below the black box. Continue turning the knob for best picture quality. Note, that if the EQ setting is too high or too low, you may not get an image. Adjust the EQ settings until an image appears, and then adjust for best picture quality.

4.5.2Skew Compensation Settings

The R1300A / R1300S2 receiver is available with an optional skew compensation module to adjust for signal timing differences due to differing pair lengths within the CAT 5 cable. Using the delay signals, skew may be compensated from 2 to 65 nanoseconds in 2 nanosecond increments on each individual color pair. If skew compensation is required, but the skew comp module is not installed, call for technical assistance.
