About the MTP 15HD Decorator-Style Receiver

The Extron MTP R 15HD RSA D is a mini twisted pair (MTP) receiver that auto-detects between audio or RS-232 serial

data on the audio/RS-232 wire pair. The receiver ﬁts into a Decorator-style wallplate and is compatible with the entire line

of Extron MTP 15HD transmitters and associated MTP products.

The Extron MTP transmitters and receivers consist of a system used for long-distance distribution of VGA or other high

resolution video, audio, or RS-232 communications.

The MTPs transmit and receive using Extron Enhanced Skew-Free A/V UTP cable. CAT 5, 5e, or 6 shielded twisted pair

(STP), unshielded twisted pair (UTP), or foil shielded twisted pair (FTP) cable can also be used.

A compatible MTP transmitter inputs high or low resolution video signals (RGB, tri-level and bi-level component video,

S-video, or composite video) and a wire pair that is either RS-232 serial signals or stereo audio. If the audio/RS-232 input

is actually audio, the transmitter sums the left and right audio channels to convert the audio to mono (L+R) format. Then

the transmitter converts the inputs to a proprietary signal and outputs that signal on an RJ-45 connector.

The MTP receiver inputs the transmitted proprietary signal on an RJ-45 connector, converts the video portion of the

signal back into its original resolution, and outputs it locally on a 15-pin HD connector. Level and peaking controls allow

you to enhance the video output for optimum display.

The receiver can also detect whether the input on the

audio/RS-232 wire pair is actually audio or serial data, convert it back to the appropriate format, and output the signal on

a 5-pin captive screw connector.

The receiver is shipped with an external 12 V power supply that accepts 100 to 240 VAC, 50-60 Hz input and provides

worldwide power compatibility.

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

NOTE: VGA video transmitters provide pre-peaking, which boosts the signal before it is transmitted.

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

(refer to the applicable transmitter manual) using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5, 5e, or 6

cable, terminated with RJ-45 connectors.

Table 1. Recommended Pre-Peak Switch Positions and Transmission Distances at 60 Hz

NOTES:

• It is possible to exceed the recommended distance; however, image quality may be reduced.

• Resolutions marked with an asterisk (*) in table 1 have the same range speciﬁcations at 75 Hz.

• 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.

Installation

The MTP R 15HD RSA D receiver can be installed in a one-gang electrical wall box with a Decorator-style wallplate cover

(supplied).

The installation must conform to national and local electrical codes and to the wallplate’s size requirements.

depth for both the wall box and the cables. The box should be at least

2.5 inches (6.4 cm) deep to accommodate the connectors and cables.

Install the cables into the wall, furniture, or conduits before installing the

wallplate.

NOTE: The wallplate unit is very deep and has a connector and a

cable pigtail on the back side (see the image on the right). Extron

recommends its 1-gang or 2-gang junction boxes which have a

depth of 2.5 inches (6.4 cm).

To install a new wall box, perform steps 1through 9below. If a suitable wall

box is already installed, perform steps 6through 9starting on the next page.

A UL Listed wall box is recommended.

1. If a wall box is not available to use for a template, use the dimensions in

on page 21 ﬁgure2 on page5 to create a template. If installing directly into furniture, cut

out the center portion of your template.

NOTE: The drawing on page 21 is not full size or to scale. Do not

scale up or print to use as a template.

2. Place the wall box (or your template) against the installation surface, and

mark the opening guidelines.

3. Cut out the material from the marked area.

4. Insert the wall box into the opening. The box or the wallplate’s rear connectors should ﬁt easily into the opening.

Enlarge or smooth the edges of the opening if needed.

5. Secure the wall box with nails or screws, leaving the front edge ﬂush with the outer wall or furniture surface (see

Figure 1. Installing the Wall Box

NOTES:

• If attaching the wall box to wood, use four #8 or #10 screws or 10-penny nails. A minimum of 0.5 inches

(1.3 cm) of screw thread must penetrate the wood.

• If attaching the wall box to metal studs or furniture, use four #8 or #10 self-tapping sheet metal screws or

machine bolts with matching nuts.

6. Feed the power cable through the opening and through the wall box punch-out holes into the box. Secure the cable

with cable clamps to provide strain relief.

NOTE: In order to ﬁt into the junction box, the TP cable and RJ-45 connector should not have a boot installed.

7. Feed the twisted pair cable pigtail out through the wall box punch-out holes. Secure the pigtail with cable clamps to

provide strain relief.

8. Trim back and/or insulate exposed cable shields with heat shrink to reduce the chance of short circuits.

To prevent short circuits, the outer foil shield can be cut back to the point where the cable exits the cable clamp.

9. Connect the power cable to the rear of the unit and the TP cable to the RJ-45 pigtail. See Rear Panel Features on

page5 for connector wiring details.

10. Connect a video and an RS-232 and/or audio device to the front panel. See Front Panel Features on page6

Level control — Level alters the video output voltage to affect the brightness of the displayed image. Adjust the

knob while viewing the displayed image to set the level/boost that provides the best picture quality.

Peaking control — Peaking affects the sharpness of a picture. Increased peaking can compensate for mid- and

high-frequency detail loss from low bandwidth system components or capacitance in long cables. The minimum

setting (at the counterclockwise limit) provides no peaking. The maximum setting (at the clockwise limit) provides

100% peaking. Adjust this control to obtain the optimum picture sharpness.

ATTENTION: Power supply voltage polarity is critical. Incorrect voltage

polarity can damage the power supply and the MTP.

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.

CAUTION:

• The two power cord wires must be kept separate while the power

supply is plugged in. Remove power before wiring.

• Les deux cordons d’alimentation doivent rester séparés tant que

l’alimentation est branchée. Coupez l’alimentation avant de faire les

raccordements.

ATTENTION: 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 direct

insertion connectors and could be pulled out.

NOTE: Do not tin the power supply leads before installing them in the direct insertion connector. Tinned wires are not

as secure in the connectors and could be pulled out.

Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Alternatively, an optional Extron PS 124 Universal 12 VDC Power Supply (part #60-1022-01) can power multiple Extron

12 VDC devices using only one AC power connector.

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 A/V UTP cable must comply with TIA/EIA T568A only.

Figure3 on page8 details the recommended termination of TP cables with RJ-45 connectors in accordance with the

TIA/EIA T568A or TIA/EIA T568B wiring standards. You can use either standard with CAT 5/5e/6 cable, but ensure that

you use the same standard on both ends of the cable.

NOTES:

• The audio data that may be carried on wire pair 3 and 6 is incompatible with the Extron TPX 88A, which cannot

switch the audio, output it locally, or break it away.

• Enhanced Skew-Free A/V 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.

Figure 3. TP Cable Termination

RS-232 Function

When the audio/RS-232 portion of the TP link is RS-232, it is either unidirectional or bidirectional, selectable by a DIP

switch.

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 set it to be bidirectional. When bidirectional is selected, the receiver can

receive commands from the transmitter as well as pass RS-232 responses back to the transmitter. See the BI-

RS232 DIP switch description (page 9) to allow bidirectional RS-232 communications.

The RS-232 link:

• 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 varies depending on baud rate and TP cable length.

ATTENTION: 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 direct insertion connectors and could

be pulled out.

Receiver Considerations

NOTE:

• Each transmitter in a system requires a separate receiver.

• Up to seven standard receivers (MTP RL 15HD RS and MTP RL 15HD A, with or without SEQ) can be

connected in series between the transmitter and the MTP R 15HD RSA D. This daisy chain is accomplished

using the standard receivers’ Buffered Output connectors. The total distance from the transmitter’s TP output to

the last receiver in the chain should not exceed the recommended distance for the resolution being used.

• The receivers’ buffered outputs do not provide pre-peaking control. The total recommended distance for an

entire daisy chain is the same as a single transmitter and receiver. The transmitter’s Pre-Peak switch for a daisy

chain or a single transmitter and receiver has the same effect on the recommended transmission distance.

• See the recommended transmission ranges in table1 on page2). The recommendations in the table apply

equally to a single transmitter and receiver as well as to a transmission daisy chain. For example, the maximum

suggested range for 1024 x 768 video is 300 feet with Pre-Peak off; 500 feet with Pre-Peak on while using one

transmitter and one receiver or one transmitter and three daisy-chained receivers.

• For daisy-chained units, the ﬁrst receiver in the chain must be at least 100 feet from the transmitter when the

Pre-Peak switch is on.

• For daisy-chained units, any receiver in the chain closer than 350 feet may experience some form of over-

peaking when the Pre-Peak switch is on.

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.

Try using the following methods to minimize or eliminate pair skew:

• Switch to Extron 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.
