About the MTP Transmitters and Receivers
The Extron MTP T 15HD A transmitter and MTP RL 15HD A and MTP RL 15HD A SEQ
receivers are a system for long-distance distribution of VGA or other high resolution video
and audio.
The MTPs are a part of the Extron compact line of basic distribution amplifiers, switchers,
transmitters and receivers, and associated video accessories.
High resolution video on a 15-pin HD connector as well as stereo audio on a 3.5 mm stereo
jack is sent to the MTP transmitter. The transmitter sums the left and right audio channels
to convert the audio to mono (L+R) format. The MTP T then converts the input video and
mono audio signals to proprietary signals and outputs them to the compatible MTP receiver
on an RJ-45 connector. A pre-peaking control allows you to boost the transmission distance
of the proprietary signal. The transmitter also makes the input video available for local use
on a 15-pin HD connector.
The transmitted proprietary signal is sent to the receiver on an RJ-45 connector and
converts the signal back into its high resolution video and mono audio components. The
receiver outputs the video on a 15-pin HD connector and the two sets of identical mono
audio signals on a single 3.5 mm captive screw connector (A series only; RS series outputs
on a RS-232 connection).
The receiver also buffers the proprietary input signal and sends it to another compatible
MTP receiver or to a daisy chain of receivers.
NOTES:
• The transmitter provides pre-peaking, which boosts the signal before it is
transmitted. The buffered output on the receiver does not provide any
pre-peaking control. The total recommended distance (see the table on page 4)
for an entire daisy chain is the same as for a single transmitter and receiver. The
Pre-Peak switch on the transmitter has the same effect on the recommended
transmission distance for a daisy chain as for a single transmitter and receiver.
• Up to eight receivers can be connected in series using Buffered Output connectors,
provided that the total distance from the twisted pair output of the transmitter to
the last receiver in the chain does not exceed the recommended distance for the
resolution being used.
The SEQ receiver also corrects the skew delay commonly encountered when CAT 5, 5e, 6,
7, or STP201 cables are used for RGB video, component video, and S-video transmission.
NOTE: An SEQ receiver should not be necessary when Extron Enhanced Skew-Free AV
UTP cable and non-C7 transmitters and receivers are used.
Each MTP transmitter and receiver model is shipped with an external desktop 12 V power
supply that accepts 100 VAC to 240 VAC, 50-60 Hz input.
Twisted Pair Cable Advantages
Twisted pair cable is smaller, lighter, more flexible, and less expensive than coaxial cable.
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 on page 4 specifies the recommended maximum
transmission distances and transmitter Pre-Peak switch positions (see figure 3, on page
e
9) using Extron Enhanced Skew-Free AV UTP cable, STP201 cable, or CAT 5, 5e, 6, or 7
cable, terminated with RJ-45 connectors.
NOTES:
• The transmitter and receiver are designed for and perform best with
Extron Enhanced Skew-Free AV UTP 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 pre-terminated 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 table on page 4 apply for a single transmitter
and receiver and for a daisy chain. For example, the maximum suggested range for
1024 x 768 video is 300 feet (90 m) with the Pre-Peak switch off and 500 feet
(150 m) with the Pre-Peak switch on, whether the system consists of one transmitter
and one receiver or a transmitter and three daisy-chained receivers.
• Extron recommends using at least 25 feet of twisted pair cable between the
transmitter and the first receiver.
• For daisy-chained units, the first receiver in the chain must be at least
100 feet (30 m) from the transmitter when the Pre-Peak switch 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 over-peaked image may appear bloomed.

Power Supply Wiring and Grounding
Figure 8 shows how to wire and ground the connector.
ATTENTION:
• Potential damage to property.
Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the transmitter or receiver. Identify the power cord negative lead
by the ridges on the side of the cord.
• To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
• The length of the exposed (stripped) copper wires is important. The ideal length is
3/16 inches (5 mm). Longer bare wires can short together. Shorter wires are not as
secure in the connector and could be pulled out.
Extron twisted pair products can be adversely affected by electrostatic discharge (ESD) if
they are not grounded correctly. To prevent malfunctions or product damage, an installer
can correctly ground an Extron twisted pair product by following the diagram in figure 8.
Ground the power port by inserting one end of the grounding wire to the negative or ground
pin on the power input connector.

NOTES:
• RJ-45 termination with CAT 5, 5e, or 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.
• For proper grounding of shielded twisted pair cable, ensure the shield around
each wire pair are all tied to the RJ-45 connectors on both ends, in accordance with
the connector specifications provided by the manufacturer.
• Extron 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 T568A standard.
• The green, brown, and blue wire pairs of this cable have virtually identical lengths
and should be used to transmit the RGB signals.
• The orange wire pair of this cable has a different length and should not be used to
transmit the RGB signals.

Skew Delay Compensation
CAT 5, 5e, 6, 7, and STP201 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 twisted pair cable is changed, the skew adjustment should need to
be made only once, during installation.
SEQ Receiver Skew Compensation
The SEQ receiver has built-in skew compensation capabilities. Adjust the equalization as
follows:
1. Zero the skew delay for Red, Green, and Blue as follows:
a. Use a small screwdriver to press and hold the Select button for 3 seconds. The
Red, Green, and Blue LEDs all go out.
b. Release the Select button.
2. Use UTP cable test equipment or examine the displayed video image with a critical eye
to determine which video signal — Red, Green, or Blue — is most shifted to the
left.
NOTE: A crosshatch test pattern or a black background with vertical white lines is
ideal for determining skew.
3. Adjust the leftmost video signal as follows:
NOTE: The SEQ receiver cannot shift the rightmost video image to the left.
a. Use a small screwdriver to press and release the Select button until the LED lights
for the left-shifted color — Red, Green, or Blue.
b. Slowly rotate the Delay control clockwise while monitoring the display.
Observe that the leftmost color shifts rightward one step at a time. Continue to
rotate the control until that color is properly converged.
NOTE: A 2-nanosecond adjustment is very fine. Up to 10 nanoseconds of delay
may be necessary before you detect a change in the display.
c. Use a small screwdriver to press the Select button one more time to save the most
recent adjustment or allow the 10-second time-out to elapse.
4. If the remaining colors are left shifted, repeat steps 2 and 3.
Non-SEQ Receiver Skew Compensation
Try using the following methods to minimize or eliminate pair skew:
•
•
Switch to Extron Enhanced Skew-Free AV UTP cable.
Add a skew compensation cable equal to the length of pair skew to the output of the
receiver.
•
Install an SEQ 100 15HD Skew Equalizer to the video output of the receiver and adjust
the skew for the leading video image.

EDID Configuration
The MTP 15HD A transmitter can either record EDID from a display device, or a
pre-programmed EDID can be selected using the rotary and DIP switches.
Recording a Display EDID
1. Turn the rotary switch to position 0.
NOTE: The vertical frequency DIP switch has no effect in this mode.
2. Connect the display device to the local monitor output connector.
NOTE: The MTP 15HD transmitter should be supplying the necessary 5 VDC to
power on the display. However, to ensure that EDID is being transmitted, power on
the display.
3. When ready to record to memory, press and release the recessed record button
(see
on page 6) to begin the recording process. The Record LED (see
on
c
b
page 6) will flash red rapidly during recording, then return to solid green after recording
is completed. At this time, the display can be disconnected. Connect the source device
to the input connector.
4. Power on or restart the source device if necessary.
Using a Pre-Programmed or User-Recorded EDID
1. If you have not already done so, connect the source device to the MTP 15HD
transmitter. Do not power on the source device at this time.
2. Set the front panel DIP switch (see
on page 6) to the required frequency
d
(50 or 60 Hz).
3. Set the rotary dial (see
on page 7) to the required position (see table below).
e
Positions 1 through E are factory installed. Position 0 is for user-recorded EDID
information. Position F passes the EDID from the display connected to the loop-out
directly back to the input.

these products in a rack:
1. Elevated operating ambient temperature — If the unit 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, install the equipment in
an environment compatible with the maximum ambient temperature (TMA = +122 °F,
+50 °C) specified by Extron.
2. Reduced air flow — Install the equipment in the rack so that safe operation and
adequate air flow is provided to the unit.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Consider the equipment nameplate ratings when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as the use of power strips).
