About this Guide
This guide contains installation, configuration, and operation information for
Extron MTP transmitters and receivers that are compatible with:
•
•
Extron Enhanced Skew-Free™ AV UTP cable
Category (CAT) 5, 5e, and 6 shielded twisted pair (STP), unshielded twisted pair (UTP), or
foil shielded twisted pair (FTP) cable.
This guide details the installation and operation of the following products:
•
•
•
MTP T 15HD RS twisted pair (TP) transmitter
MTP RL 15HD RS receiver with loop-through
MTP RL 15HD RS SEQ receiver with loop-through and skew equalization
In this guide:
•
•
The term "transmitter" refers specifically to the MTP T 15HD RS transmitter.
The term "receiver" refers to either of the receiver models — the MTP RL 15HD RS or
MTP RL 15HD RS SEQ.
•
The term "SEQ receiver" refers specifically to the MTP RL 15HD RS SEQ receiver with
skew equalization capabilities.
About the MTP Transmitters and Receivers
The Extron MTP T 15HD RS transmitter and MTP RL 15HD RS and MTP RL 15HD RS SEQ
receivers are a system for long-distance distribution of VGA or other high resolution video
and RS-232 serial communications.
The MTPs are a part of the Extron compact line of basic distribution amplifiers, switchers,
transmitters, receivers, and associated video accessories.
High resolution video is sent to the MTP transmitter on a 15-pin HD connector. The
transmitter passes RS-232 serial data or control signals on a 3.5 mm 3-pin captive screw
connector. The transmitter converts the video and RS-232 signals to proprietary signals and
outputs them to the compatible MTP receiver on an RJ-45 connector. 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 serial data components. The receiver
outputs the video on a 15-pin HD connector. The serial communications are passed on a
3.5 mm 3-pin captive screw connector.

The RS-232 portion of the twisted pair link:
•
Can be bidirectional in a one-receiver system; that is, the receiver can receive commands
from the transmitter and pass RS-232 responses to the transmitter.
NOTE: By default, the RS-232 portion of the twisted pair link is unidirectional only
from the transmitter to the receiver. Use the internal jumpers in the receiver
to enable bidirectional communication in a single-receiver system only
(see "Pre-Installation — RS-232 Jumper" on page 5).
•
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 twisted pair cable length.
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 the 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, or 6
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 is used.
Each MTP transmitter and receiver model is shipped with an external desktop 12 VDC 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 item on page 9)
e
using Extron Enhanced Skew-Free AV UTP cable or CAT 5, 5e, or 6 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 overpeaked image may appear bloomed.

Pre-Peak switch — The Pre-Peak switch alters the twisted pair signal output to correct
for long cable runs. See the table on page 4 for suggested switch settings based on the
transmitted video format and transmission distance.
e
NOTES:
• Use the internal jumpers to enable bidirectional communication (see
"Pre-Installation — RS-232 Jumper" on page 5).
• The length of the exposed wires in the stripping process is critical. The ideal length is
3/16 inches (5 mm). If the exposed section is longer, the exposed wires may touch,
causing a short circuit between them. If it is shorter, the wires can be easily pulled
out, even if tightly fastened by the captive screws.
• Do not tin the wires. Tinned wire does not hold its shape and can become loose over
time.
Output connector — Connect one end of a twisted pair cable to this RJ-45 female
connector on the transmitter. Connect the free end of the same twisted pair cable to
the RJ-45 female connector on the receiver. See "Twisted Pair Cable Termination" on
page 13 to wire the RJ-45 connectors.

Power Supply Wiring
Figure 8 below shows how to wire 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.
• 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.
To verify the polarity before connection, plug in the power supply with no load and check
the output with a voltmeter.

• 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, and 6 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 three 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 RS 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 figure 2 on page 6) to begin the recording process. The Record LED (see
on
c
b
figure 2 on 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 figure 2 on page 6) to the required frequency
d
(50 or 60 Hz).
3. Set the rotary dial (see
on figure 2 on page 6) to the required position (see the table
e
in figure 12). 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.
