• Twisted Pair (TP) Cable Advantages
CAUTION: Do not connect this device to a computer data or telecommunications
network.
About the MTP 4T 15HD RS
The Extron MTP 4T 15HD RS Quad MTP Twisted Pair Transmitter consists of four
MTP T 15HD RS transmitters in a single enclosure. This set of transmitters and the Extron
MTP RL 15HD RS and MTP RL 15HD RS SEQ receivers provide a means to distribute VGA or
other high resolution video and RS-232 serial communications across long distances.
The MTPs transmit and receive over the Extron Enhanced Skew-Free™ AV UTP cable or over
CAT 5, 5e, or 6 shielded twisted pair (STP), unshielded twisted pair (UTP), or foil shielded
twisted pair (FTP) cable.
The MTP 4T 15HD RS can support four transmitter/receiver systems. Each system requires a
transmitter and at least one connected compatible MTP receiver. Additional receivers can be
daisy chained.
NOTE: In this manual the term “transmitter assembly” refers to the MTP 4T 15HD RS.
Each of the MTP transmitters in the assembly inputs a set of high resolution or low
resolution video signals (RGB, component video, S-video, or composite video) on a 15-pin
HD connector. Each transmitter also passes RS-232 serial data or control signals on 3.5 mm
3-pin captive screw connectors. The transmitters convert the video and RS-232 signals to
proprietary signals and each outputs its set of signals to the compatible MTP receivers on an
RJ-45 connector. The transmitters also make each video input available for local use on 15pin HD connectors.
Each receiver inputs the transmitted proprietary signal on an RJ-45 connector, converts the
signal back into its high resolution video and serial data components, and outputs it locally.
MTP 4T 15HD RS • Introduction 1
The RS-232 portion of the TP link:
• Can be bidirectional in each system that includes just one receiver (not a daisy
chain); that is, the receiver can receive commands from the transmitter and pass
RS-232 responses back to the transmitter.
NOTE: By default, the RS-232 portion of the TP link is unidirectional only,
from the transmitter to the receiver. If there is only one receiver in
the system, you can configure that receiver for bidirectional RS-232
communications. Refer to the MTP 15HD RS Series User Guide.
• Supports software flow control (XON, XOFF).
NOTE: Hardware flow control is not supported.
• Supports full duplex and half duplex operation.
• Supports any baud rate (up to 38,400), data bits, parity, stop bits, and data format
without configuration.
NOTE: Higher rates are possible, but performance will vary as a function of
baud rate and TP cable length.
Up to eight receivers can be connected in series to a single transmitter, 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.
NOTE: Each individual transmitter provides pre-peaking, which boosts the signal before
it is transmitted. The receiver does not provide any pre-peaking control. The
total recommended distance (see page 3) 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.
The SEQ version of the receiver also corrects the skew delay (misconvergence) commonly
encountered when using CAT 5, 5e, or 6 TP cables for RGB video and component video
transmission.
NOTE: An SEQ receiver should not be necessary when Extron Enhanced Skew-Free AV
UTP cable is used.
All four transmitters in the MTP 4T 15HD RS are powered by a single internal 100 VAC to
240 VAC, 50/60 Hz, 20 watts power supply that provides worldwide power compatibility.
MTP 4T 15HD RS • Introduction 2
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 Distance
• The maximum distance is determined by the frequency and resolution of the signal
that is input to the transmitter. The table below specifies the recommended maximum
transmission distances and transmitter Pre-Peak switch positions (see item e on
page 7) using Extron Enhanced Skew-Free AV UTP cable or UTP CAT 5, 5e, or 6 cable,
terminated with RJ-45 connectors.

suggested range for 1024 x 768 video is 300 ft. (90 m) with Pre-Peak off
and 500 ft. (150 m) with Pre-Peak on whether the system consists of one
transmitter and one receiver or a transmitter and three daisy-chained receivers.
• For a daisy-chained system, the first receiver in the chain must be at least
100 ft. (30 m) from the transmitter when the Pre-Peak switch is on.
• For a daisy-chained system, any receiver in the chain closer than 350 ft.
(105 m) may experience some form of over-peaking when the Pre-Peak switch
is on. An overpeaked image may appear bloomed.

Rack Mounting
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
unit into a rack.
1. Elevated operating ambient temperature — If the equipment is installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, consider installing the
equipment in an environment compatible with the maximum 122° F (50° C) ambient
temperature (Tma) specified by the manufacturer.
2. Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as the use of power strips).

e Pre-Peak switch
— The Pre-Peak switch alters the TP signal output to correct for
long cable runs. See the table on page 3 for suggested switch settings based on the
transmitted video format and transmission distance.
f Transmitter Output connector — Connect one end of a TP cable to this RJ-45 female
connector on the transmitter. Connect the free end of the same TP cable from the
transmitter to the receiver’s Input RJ-45 female connector. See “TP Cable Termination”
below to properly wire the RJ-45 connectors.
CAUTION: Do not connect this device to a computer data or telecommunications
network.
TP Cable Termination
NOTE: RJ-45 termination with CAT 5, CAT 5e, or CAT 6 cable must comply with the
TIA/EIA T568A or TIA/EIA T568B wiring standards for all connections.
RJ-45 termination with Skew-Free AV UTP cable must comply with TIA/EIA
T568A only.
Figure 4 shows the recommended termination of TP cables in accordance with the TIA/EIA
T568A or TIA/EIA T568B wiring standards. You can use either standard with CAT 5, 5e, or 6

NOTE: Enhanced Skew-free AV cable is not recommended for Ethernet/LAN
applications. This cable is specially designed for compatibility with Extron
twisted pair products that are wired using the TIA/EIA 568 A standard.
The green, brown, and blue pairs of this cable have virtually identical lengths and
should be used to transmit the RGB signals.
The orange pair of this cable has a different length and should not be used to
transmit the RGB signals.
MTP 4T 15HD RS • Installation and Operation 7
Receiver considerations
1
NOTES: • 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.
Front Panel Controls and Indicators

a Power LED — When lit, this LED indicates power is applied to the MTP 4T 15HD RS.
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: Unless the TP cable is changed, the skew adjustment should only need to be
made once, during installation.
MTP 4T 15HD RS • Installation and Operation 8
SEQ Receiver Skew Compensation
The MTP 15HD RS SEQ receiver has built-in skew compensation capabilities. Refer to the
MTP 15HD RS Series User Guide for details.
Non-SEQ Receiver Skew Compensation
Try using the following methods to minimize or eliminate pair skew:
• Switch to the Extron Enhanced Skew-Free AV UTP cable.
• Add a skew compensation cable equal to the length of pair skew to the receiver’s
output.
• Install an SEQ 100 15HD Skew Equalizer on the receiver’s video output and adjust
the skew for the leading video image.
