TP Cable Advantages
Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial
cable. These TP products make cable runs simpler and less cumbersome. Termination of the
cable with RJ-45 connectors is simple, quick, and economical.
CAUTION: Do not connect this device to a computer data or telecommunications
network.
Transmission distances
The maximum distances are determined by the frequency and resolution of the video signal
being routed and by which MTPX Plus inputs and outputs (TP or local) are in the full (video
source to display) routing path. The tables on the following pages specify the recommended
maximum transmission distances using Extron Enhanced Skew-Free™ A/V UTP cable or UTP
CAT 5, 5e, or 6 cable, terminated with RJ-45 connectors.
NOTES: • For all three tables, the minimum TP cable length should be 25 feet (7.5 m).
• RS-232 serial communications can be sent up to 1,000 feet (300 m) from
the MTP transmitter output (or RS-232 output insert) to the MTP receiver TP
input.
• It is possible to exceed the recommended distances; however, image quality
may be reduced.
• Daisy-chaining MTPX units by connecting a TP output from one matrix
switcher to the TP input of a second matrix switcher is not recommended.
Daisy chaining in this manner can lead to excessive video smearing.
• The transmitters, receivers, and matrix switcher are designed for and perform
best with Extron Enhanced Skew-Free A/V cable terminated in accordance
with the TIA/EIA T 568A wiring standard. CAT 5, 5e, and 6 cables are
acceptable, but less preferable. We also recommend the use of preterminated
and tested cables. Cables terminated on site should be tested before use to
ensure that they comply with Category 5 specifications.
• Daisy-chaining MTPX units by connecting a TP output from one matrix
switcher to the TP input of a second matrix switcher is not recommended.
Daisy chaining in this manner can lead to excessive video smearing.
• The recommendations shown in the tables apply equally for a transmission
line that consists of a single transmitter, the switcher, and receiver and for a
transmission line that encompasses a transmission daisy chain. For example,
the maximum suggested output range (MTPX Plus TP output to MTP receiver)
for 1024 x 768 video is 450 feet (135 m) (
table 1 [
2
]) or 500 feet (150 m)
( table 2 [ 4 ]), whether the transmission line consists of the switcher and a
single receiver or the switcher and three daisy-chained receivers. This range
can be extended to 500 feet or 550 feet if the output is one that has the
Pre-Peak function and the function is turned on.
• For daisy-chained units, the first receiver in the chain should be at least
50 feet (15 m) from the switcher when the Pre-Peak feature is on.
• For daisy-chained units, any receiver in the chain closer than 350 feet (105 m)
may experience some form of over-peaking when the Pre-Peak switch is on.
An overpeaked image may appear bloomed.
