Twisted pair (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.

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 below and
on the next page 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.

• For both tables, the minimum TP cable length should be 50 ’ (15 m).
• RS-232 serial communications can be sent up to 1,000 ’ (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.
• For both tables, the MTPX output can be extended by 50 ’ (15 m) for those
outputs (MTP transmitter or MTPX) that have a Pre-Peak feature that is
turned on.
• 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 568 A 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.
• The recommendations shown in the tables apply equally for a transmission
line consisting 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’ (135 m), 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
’ 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’
(15 m) from the switcher when the Pre-Peak feature is on.
• For daisy-chained units, any receiver in the chain closer than 350’ (105 m)
may experience some form of over-peaking when the Pre-Peak switch is on.
An overpeaked image may appear bloomed.
