SERVSWITCH™ WIZARD EXTENDER
The first section of the report indicates the length differences between the twisted pairs that are carrying the red, green, and blue color signals. One of the colors will have a reported length difference of “+0.0M”; this is the color carried by the shortest twisted pair. The other reported differences are how much longer the other pairs are than the shortest one.
TECHNICAL NOTE
Each meter of the length differences between the pairs that the Extender reports is equivalent to 5 nanoseconds of delay. For comparison, you can get a rough estimate of your system’s
For example, if the maximum reported difference is 1.5 meters, the delay between color signals will be 1.5 x 5 ns = 7.5 ns. If the screen resolution being used is 1024 x 768 x 75 Hz, the pixel time is roughly
1 / (1024 x 768 x 75) = 16.9 ns. Consequently, the color split will be less than half a pixel time and so is unlikely to be noticeable.
The second section of the report indicates which of the Skew Compensator’s
To compensate for the skew, set the Skew Compensator’s switches as indicated in the report and use a second cable to insert it into the
NOTE
Because the cabling between the CPU and the transmitter can itself introduce some signal skew, sometimes setting the Skew Compensator manually, by trial and error, produces better results than relying on the skew report. For any given wire pair (color), switches 1 and 2 each introduce a
