3.5 Skew Adjustment for URA-SKU and URA-XT Receivers
URA-SKU and URA-XT receivers have the ability to adjust for cable skew in the
individual colors.
• Apply power to the receiver. Wait until all LED’s are turned off
• Press the SEL button once to enter Adjustment-mode.
• In Adjustment-mode, all three (3) LEDs will be ON.
• Press the SEL button once to enter the Adjustment mode. Press the SEL
button again to light only one of the (3) Red, Green or Blue LEDs. As you
press SEL the Red, Green, and Blue LEDs will light up one at a time.
• The UP and DOWN buttons are used to move the selected color
component to the left and right. Pressing both buttons at the same time
resets all skew adjustments.
• While using the UP and DOWN buttons, if an upper or lower limit of
adjustment is reached, the LED’s will blink for each continued press of the
UP or DOWN button.
• To exit the Adjustment mode at any time, press the SEL button until all
LED’s are OFF (the unit also has a built-in 1 minute timeout).
3.6 Signal Adjustment for the Daisy Chain
There are no specific procedures for adjusting the URA-XT’s other than the order of
adjustment.
The URA-XT’s RJ45 (CATx) output is the video signal AFTER IT HAS BEEN
ADJUSTED.
The receiver unit closest to the sender must be adjusted first.
Set the high frequency compensation first and then adjust the skew. Since the
effects in the daisy chain are cumulative, we recommend that you adjust the
brightness (see section 3.3 above).
Remember, if the calibration is off on a URA-XT in the middle of a daisy chain and
you adjust the device settings you must then check the rest of the downstream
devices and if necessary; make additional adjustments on those devices as well.
