The RS-232 portion of the TP link:
• Can be bidirectional in each system that consists of 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.
N
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
manual.
• Supports software flow control (XON, XOFF).
N
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.
N
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.
N
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 1-4) for an entire daisy
chain is the same as for a single transmitter and receiver.
The transmitter’s Pre-Peak switch has the same affect 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.
N
An SEQ receiver should not be necessary when Extron
Enhanced Skew-Free A/V 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.
C
Do not connect this device to a computer data or
telecommunications network.
About the MTP 4T 15HD RS
The Extron MTP 4T 15HD RS 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 Extron’s Enhanced SkewFree A/V 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.
N
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 15-pin 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.

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 2-6) using Extron Enhanced Skew-Free A/V UTP cable
or UTP CAT 5, 5e, or 6 cable, terminated with RJ-45 connectors.

It is possible to exceed the recommended distance;
however, image quality may be reduced.
N
The MTP units 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.
N
The recommendations shown in the table on page 4
apply 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’ (90 m) with
Pre-Peak off and 500’ (150 m) with Pre-Peak on whether
the system consists of one transmitter and one receiver or
a transmitter and three daisy-chained receivers.
N
For a daisy-chained system, the first receiver in the chain
must be at least 100’ (30 m) from the transmitter when
the Pre-Peak switch is on.
N
For a daisy-chained system, 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.

(Component Video)
By default, each transmitter in the MTP 4T 15HD RS is
configured to send bi-level (normal) sync. For HDTV/component
video applications, the transmitter can be configured to send
tri-level sync as follows:
1. If applicable, disconnect all power and other cables,
remove the transmitter from its installation location, and
remove any previously installed mounting brackets.
2. Remove the eight screws (three on each side and two on
top) from the transmitter assembly and lift the top cover
off of the transmitter (figure 2-1).

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.
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.

N
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 a system, a jumper
within the receiver allows the RS-232 communication
to be bidirectional. Refer to the MTP 15HD RS Series
manual.
e
Pre-Peak switch — The Pre-Peak switch alters the TP signal
output to correct for long cable runs. See the table on page 1-4
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.
C
Do not connect this device to a computer data or
telecommunications network.
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” on the next page to properly wire the
RJ-45 connectors.
TP cable termination
N
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 A/V UTP cable must
comply with TIA/EIA T568A only.
Figure 2-5 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
cable, but use the same standard on both ends of the cable.

Enhanced Skew-free A/V cable is not recommended
for Ethernet/LAN applications. This cable is specially
designed for compatibility with Extron’s 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.

Receiver considerations
N
Each transmitter in the assembly requires a separate
receiver.
N
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 affect on the recommended transmission distance
for a daisy chain as for a single transmitter and receiver.
N
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.
N
See the recommended transmission ranges in the table
on page 1-4. 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’ with
Pre-Peak off and 500’ with Pre-Peak on for either one
transmitter and one receiver or a transmitter and three
daisy-chained receivers.
N
For daisy-chained units, the first receiver in the chain
must be at least 100’ from the transmitter when the PrePeak switch is on.
N
For daisy-chained units, any receiver in the chain closer
than 350’ may experience some form of over-peaking
when the Pre-Peak switch is on.
N
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 manual.
Front Panel Controls and Indicators
Figure 2-6 shows the front panel of the MTP 4T 15HD RS and its
power LED.

Power LED — Indicates power is applied to the

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.
N
Unless the TP cable is changed, the skew adjustment
should only need to be made once, during installation.
SEQ receiver skew compensation
The MTP 15HD RS SEQ receiver has built-in skew compensation
capabilities. Refer to the MTP 15HD RS Series manual for details.
Non-SEQ receiver skew compensation
Try using the following methods to minimize or eliminate pair
skew:
• Switch to Extron’s Enhanced Skew-Free A/V 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.
