CAT5e cable rather than CAT6 since CAT5 cables have better twist ratio match than CAT6 does 4 Configuration Operation 4 1 Why Cable Compensation All cables attenuate reduce the high frequency components of the video signal that is being transmitted The longer the cable the more signal loss If not compensated for this signal loss will result in blurry and smeared images being displayed The image quality depends on the resolution and level of detail in the image The Compact CAT5 Audio Video Receiver has one of the most precise and complex equalization techniques in the industry and allows for full recovery of the original signal s bandwidth Make this adjustment using a test pattern that is designed to depict and exaggerate this effect Connect a PC to the video input and display a test pattern The table below lists the recommended maximum distances from sender to the receiver depending on the resolution used Refresh Rate Table 4 1 Recommended maximum CATx cable length from sender to the receiver o A Resolution Compact CAT5 Audio Video Receiver 4 2 Compensation Adjustment Procedure e Press the SELECT button once to enter the adjustment mode that is without first hitting SELECT button the up and down arrows are inactive e In adjustment mode all 3 LEDs on the unit will be turned on The UP or DOWN buttons can now be used to adjust the high frequency HF compensation u
