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.
NOTE:
• Each transmitter in the assembly requires a separate receiver.
• The receivers' buffered outputs do not provide pre-peaking control. The total
recommended distance for an entire daisy chain is the same as for a single
transmitter and receiver. The transmitter's Pre-Peak switch has the same effect
on the recommended transmission distance for a daisy chain as for a single
transmitter and receiver.
• Up to 8 receivers can be connected in series to a transmitter using the
receivers' Buffered Output connectors, provided that the total distance from
the transmitter's TP output to the last receiver in the chain does not exceed the
recommended distance for the resolution being used.
• See the recommended transmission ranges in the table 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 ft. with Pre-Peak off and 500 ft.
with Pre-Peak on for either one transmitter and one receiver or a transmitter
and three daisy-chained receivers.
• For daisy-chained units, the first receiver in the chain must be at least 100 ft.
from the transmitter when the Pre-Peak switch is on.
• For daisy-chained units, any receiver in the chain closer than 350 ft. may
experience some form of over-peaking when the Pre-Peak switch is on.
• If a receiver is the last receiver in a daisy chain, its end unit DIP switch setting
needs to be changed. Refer to the MTP 15HD RS Series User Guide.

Power LED — When lit, this LED indicates power is applied to the MTP 4T 15HD RS.
Unless the TP cable is changed, the skew adjustment should only need to be
made once, during installation.
