• See the recommended transmission ranges on page 3. The recommendations in
the table apply equally for a single transmitter and receiver and for a transmission daisy
chain. For example, the maximum suggested range for 1024 x 768 video is 300 feet
with Pre-Peak off and 500 feet with Pre-Peak on for either one transmitter and one
receiver or one transmitter and three daisy-chained receivers.
• For daisy-chained units, the first receiver in the chain must be at least 100 feet from the
transmitter when the Pre-Peak switch is on.
• For daisy-chained units, any receiver in the chain closer than 350 feet may experience
some form of over-peaking when the Pre-Peak switch is on.
Skew Delay Compensation
CAT 5/5e/6 TP cable can lead to registration errors between the red, green, and blue
video signals. Pair skew can be measured with test equipment or identified by viewing a
crosshatch test pattern with a critical eye to determine if either the red, green, or blue video
image leads (appears to the left of) the other two video images.
Try using the following methods to minimize or eliminate pair skew:
• Use an SEQ receiver or install an SEQ 100 15HD Skew Equalizer on the receiver video
output and adjust the skew for the leading video image.
• Switch to Extron Enhanced Skew-Free A/V UTP cable.
• Add a skew compensation cable equal to the length of pair skew to the receiver output.
