About this Manual

This manual describes the function, installation, conﬁguration, and operation of the MTP SW6 twisted pair switcher.

About the MTP SW6 Switcher

The Extron MTP SW6 is a 6-input, 1-output twisted pair switcher that is compatible with the entire line of Extron MTP transmitters and receivers.

The Extron MTP transmitters and receivers are a system for long-distance distribution of video and either audio or RS-232 communications. The MTPs transmit and receive over Extron Enhanced Skew-Free™ 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 switcher receives up to six sets of signals from compatible MTP devices on RJ-45 connectors (ﬁgure 1). You can select one input to output to a compatible MTP device on an RJ-45 connector. The signal sets are comprised of high or low resolution video signals (RGB, bi-level or tri-level component video, S-video, or composite video) and can also include either RS-232 serial signals or audio.

MTP SW6 • Introduction 1

NOTE: The remote power capabilities of certain MTP models are not supported by this

switcher.

The MTP switcher has image enhancement features that allow you to correct for long distance transmissions and skew:

• Level and Peaking controls enhance the TP signals received on the inputs.

• A Pre-Peaking control enhances the TP output for optimum display.

• Delay (skew correction) controls correct for skew delay (misconvergence) commonly

encountered when using CAT 5, 5e, or 6 TP cables for RGB video, and component video transmission.

NOTE: Skew correction should not be necessary when Extron Enhanced Skew-Free

A/V UTP cable is used and the transmission distance is less than 1,000 feet (300 m).

Bidirectional RS-232 signal from a dedicated source (rather than from the selected input) can be directly inserted into the signal set routed to the TP output. You can even route RS-232 on a link that is normally audio, such as to an MTP R 15HD RSA D receiver, which can autodetect whether the signal input to it includes an audio component or an RS-232 component.

The MTP switcher is housed in a rack-mountable, 1U high, half rack-width metal enclosure. This switcher is shipped with an external 12 V power supply that accepts 100 to 240 VAC, 50 Hz or 60 Hz input and provides worldwide power compatibility.

RS-232 Function

When the TP link includes RS-232 signals, they are unidirectional (switcher to receiver).

NOTE: The RS-232 insert signal path is bidirectional.

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 baud rates 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.

MTP SW6 • 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

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. Figure 2 and Table 1, on the next page, deﬁne the switcher

input cables ( transmission distances on the input and output. Table 1 also deﬁnes the output Pre-Peak switch positions (item d on page 10) using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5, 5e, or 6 cable, terminated with RJ-45 connectors.

NOTES: • It is possible to exceed the recommended distance; however, image quality

• The MTP units are designed for and perform best with Extron Enhanced

• Resolutions marked with an asterisk in table 1 have the same range

) and output cables (2) and specify the recommended maximum

may be reduced.

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.

MTP SW6 • Introduction 4

Features

Compatible with all Extron MTP Series Twisted Pair products — Broad compatibility with all MTP products enables design ﬂexibility when selecting components, and allows the use of an economical CAT 5-type cable infrastructure for A/V system integration.

Dynamic input skew equalization — Adjustments are stored in memory for each input, maintaining RGB color alignment at all times.

Video level and peaking compensation on each input — Actively compensates for input signal attenuation for various cable lengths, resulting in a brighter and sharper image.

Switchable video pre-peaking for output — Provides additional compensation for optimal performance on the longest cable runs, ensuring the highest quality signal at the display.

Local dual mono audio output — A line level output on the product splits mono audio feed from the MTP transmitter into two channels for direct connection of audio equipment that is located within the same rack as the MTP SW6.

Local audio output volume adjustment and muting — A local line level output has volume and muting control via RS-232 that can be set dynamically to feed an audio ampliﬁer, eliminating the need for a preampliﬁer in many systems.

Auto-input switching — Automatically switches to the highest-numbered input with an active video signal.

Local RS-232 insertion port — Allows direct insertion of bi-directional serial control signals into the MTP output. This eliminates the need for additional control system wiring to the remote display and extends the serial control beyond the recommended 100-foot distance.

RS-232 and contact closure control — Provides versatile control options, simplifying remote control integration.

External universal power supply included — Provides worldwide power capability.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of an MTP SW6 unit onto a rack.

1. Elevated operating ambient — If 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 ambient temperature speciﬁed by the manufacturer [Tma = +32 to +122 °F (0 to +50 °C)].

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.

NOTE: The remote power capabilities available with certain MTP models are not

supported by this unit; the transmitter, switcher, and receiver must all be powered.

Input connectors — Connect up to six TP cables from transmitters to these RJ-45

female connectors. See TP cable termination to wire the RJ-45 connectors.

CAUTION: Do not connect this device to a computer data or telecommunications

network.

NOTES: • See Table 1 for recommended transmission ranges.

• You must conﬁgure the switcher for the appropriate content on the audio/RS-232 wire pair (pins 3 and 6) for each TP input. See the

Audio/RS-232 TP input (wire pair 3 and 6) conﬁguration

SIS commands.

• For best results, use a combined cable length of at least 50 feet (15 m) between the transmitter and the receiver on the MTP SW6 output.

• 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 Enhanced Skew-Free A/V UTP cable must comply with TIA/EIA T568A only.

• When low resolution MTPs (S-video and composite video) are the TP inputs, the MTP SW6 audio circuits are compatible only with the newer generation, mono audio models. See the appropriate MTP transmitter/receiver user’s manual to determine which MTP models you have.

Output connector — Connect one end of a terminated TP cable to this RJ-45 female

connector.

Connect the free end of the same TP cable from the switcher to the RJ-45 female

connector on a compatible MTP receiver.

See TP Cable Termination to properly wire the RJ-45 connectors.

Figure 10. Power connector wiring

CAUTION: Always use a power supply supplied and or speciﬁed by Extron. Use of an

unauthorized power supply voids all regulatory compliance certiﬁcation and may cause damage to the supply and the end product. Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently ﬁxed to building structure or similar structure.

Power supply voltage polarity is critical. Incorrect voltage polarity can

damage the power supply and the unit. The ridges on the side of the cord (ﬁgure 10) identify the power cord negative lead.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

WARNING: The two power cord wires must be kept separate while the power supply

is plugged in. Remove power before wiring.

CAUTION: The length of the exposed (stripped) copper wires is important. The

ideal length is 3/16 inch (5 mm). Longer bare wires can short together.

Shorter wires are not as secure in the 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.

Rather than the included power supply, you can use an optional Extron PS 123 Universal 12 VDC Power Supply, part #60-814-01, can power multiple Extron 12 VDC devices using only one AC power connector.

TP cable termination

RJ-45

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 11 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: • 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 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.

MTP SW6 • Installation and Operation 13

Receiver Considerations

• 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.

• See the recommended transmission ranges in Table 1. The recommendations in the

table apply equally for the switcher and one receiver and for a transmission daisy chain. For example, the maximum suggested range for high quality transmission of 1024 x 768 video is 600 feet between either the switcher and one receiver or the switcher and three daisy-chained receivers.

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

the switcher 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.

• 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’s Manual that applies to your receiver or details.

Input Buttons and LEDs — When the auto switch mode is off, these buttons select

the input. The LED for the selected input lights.

The LEDs continue to indicate the selected input when the auto switch mode is on. If

no input LED is lit, no input has active sync pulses and no input is selected.

NOTE: Front panel input selection cannot be performed when the auto switch

mode is on (Auto Switch [a] is lit).

Mode button — Use this button, with either the Auto or the Normal button, to

manually turn auto switch mode on or off. This control is a secondary function of the Input 1 button.

Normal button — Use this button, with the Mode button, to manually turn auto

switch mode off. This control is a secondary function of the Input 2 button.

Auto button — Use this button, with the Mode button, to manually turn auto switch

mode on. This control is a secondary function of the Input 3 button.

Delay Select button — This recessed button selects the red, green, or blue video

signal to adjust and resets all three video signals to a skew delay of zero nanoseconds.

Use a Tweeker to press and release this button to select among the red, green, or blue

video signal to adjust. The selected signal is indicated by the Delay Red, Green, and Blue LEDs (g).

The switcher automatically saves the setting for the video signal that is being

deselected when you push this button or when the selection times out after 10 seconds.

Press and hold this button for approximately 3 seconds to zero the skew delay for red,

green, and blue. The Delay Red, Green, and Blue LEDS (g) all turn off. Release the button.

Delay Red, Green, and Blue LEDs — These LEDs Indicate the video signal that is

that the control has reached the minimum (counterclockwise rotation) or maximum (clockwise rotation) limit.

Level control — The Level control 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 while viewing the displayed image to obtain the optimum picture sharpness.

NOTES: • The switcher must be in normal (manual) mode for contact closure to work.

• Audio breakaway (available via SIS or Windows-based control program

control only) is disabled in auto switch mode; audio always follows video.

Turn auto switch mode on as follows:

1. Press and hold the Mode (Input 1) button.

2. Press and release the Auto (Input 3) button. The Auto Switch Active LED lights.

3. Release the Mode button.

NOTE: Manual switching is disabled.

Turn auto switch mode off as follows:

1. Press and hold the Mode (Input 1) button.

2. Press and release the Normal (Input 2) button. The Auto Switch Active LED goes off.

3. Release the Mode button.

NOTE: When the switcher exits auto switch mode, it deselects all inputs (no

output).

MTP SW6 • Installation and Operation 16

Optimizing the Video

Most MTP transmitters and the MTP SW6 output have a pre-peaking feature. Set these features as follows for the best image quality:

1. For inputs from MTP T 15HD products only — If the cable between the MTP

transmitter and the MTP SW6 is > 300 feet, turn the transmitter’s Pre-Peak switch on. For shorter cables, turn the switch off.

2. For the output — If the cable between the MTP SW6 and the receiver is > 300 feet,

turn the switcher’s Pre-Peak switch on. For shorter cables, turn the switch off.

NOTE: Unless the TP cable lengths are changed, these settings should need to be

Level/Peaking Setting

1. Connect an oscilloscope (preferred) or a monitor (acceptable) to the switcher’s output

via a very short (less than 25 feet [7.5 m]) TP cable and a compatible MTP receiver).

2. If using an oscilloscope, apply a white ﬁeld test pattern to the input to be optimized

via an MTP transmitter. If using a monitor, apply a grayscale or Color Bars test pattern to the input to be optimized via an MTP transmitter.

TIP: The Extron VTG 300 or VTG 400 are recommended to provide the test

made only once, during installation.

pattern.

3. Select the input to be optimized.

4. Observe the oscilloscope or the monitor with a critical eye while you adjust the front

panel input level and peaking controls to compensate for signal loss between the transmitter and the MTP SW6.

5. If necessary, repeat steps 1 through 4 for each input.

6. If level/peaking and skew adjustments are available on the connected receiver(s), set

them in accordance with the applicable MTP receiver product manual.

7. Disconnect the oscilloscope or monitor connected in step 1.

NOTES: • A simpler way to set the input level/peaking is to use the optional

MTP signal generator and the auto calibration function on each input, available as an SIS command. See the Auto level and peaking

adjustment SIS command.

• The auto calibration function compensates for signal losses on the

inputs only. Compensate for signal losses on the output via the connected receivers’ level and peaking controls.

MTP SW6 • Installation and Operation 17

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: Skew correction should not be necessary when Extron Enhanced Skew-Free A/V

UTP cable is used and the transmission distance is less than 1,000 feet (300 m).

NOTE: Unless the TP cable lengths are changed, these settings should need to be made

only once, during installation.

NOTE: For best results, repeat the skew compensation for each input.

The switcher has built-in skew compensation capabilities for its TP output. Adjust the equalization as follows:

1. Select an input

2. Zero the skew delay for red, green, and blue as follows: a. Use a Tweeker or other small screwdriver to press and hold the Delay Select

button for 3 seconds. The Delay Red, Green, and Blue LEDs all go out.

b. Release the Delay Select button.

3. 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.

TIP: The Extron VTG 300 or VTG 400 are recommended to provide a crosshatch

test pattern, which is ideal for determining skew. A black background with vertical white lines can also be useful.

4. Adjust the leftmost video signal as follows:

NOTE: The switcher cannot shift the rightmost video image to the left.

a. Use a Tweeker or other small screwdriver to press and release the Delay Select

button until the LED lights for the left-shifted color — Delay Red, Green, or Blue.

b. Slowly rotate the Delay Adjust 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 Tweeker or other small screwdriver to press the Delay Select button one

more time to save the most recent adjustment or allow the 10-second timeout to elapse.

5. If one of the remaining colors is left shifted, repeat steps 3 and 4.

6. Repeat step 1 through 5 for each input.

Host-to-Interface Communications

SIS commands consist of one or more characters per ﬁeld. No special characters are required to begin or end a command character sequence. When a command is valid, the unit executes the command and sends a response to the host device. All responses from the unit to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.

Symbol Deﬁnitions

Symbols (variables), deﬁned on the next page, are used throughout the Unit-Initiated

MTP SW6 • Remote Control 25

Windows-Based Program Control

The Windows-based Extron Universal Switcher Control Program, which communicates with the switcher via the Remote port, provides an easy way to conﬁgure and operate the MTP SW6 switcher. The program is compatible with Windows 2000 and Windows XP or higher versions.

Installing the Software

The program is contained on the Extron Software Products DVD. Install the software as follows:

1. Insert the disk into the drive. The Extron software DVD window should appear

automatically (ﬁgure 14).

Figure 14. Software CD window

NOTE: If the window does not self-start, run Launch.exe from the DVD.

2. Click the Software tab (ﬁgure 14).

3. Scroll to the desired program and click Install (ﬁgure 15).

Figure 15. Software installation

4. Follow the on-screen instructions. By default, the installation of the Universal

Switchers Control Program creates a C:\Program Files\Extron\UniversalSwitcher folder, and it places four icons into a group folder named “Extron Electronics\Universal Switcher.” The four installed icons are:

о Check for Universal Switcher Updates о Uninstall Universal Switcher о Universal Switcher Control Program о Universal Switcher Help

MTP SW6 • Remote Control 26

Using the Software

Run the program as follows:

1. Click Start > Programs > Extron Electronics > Universal Switcher (New) >

Universal Switcher Control Pgm.

2. Click the comm port that is connected to the switcher’s RS-232 port.

3. The Extron Universal Switcher Control Program window (ﬁgure 16) displays the

selected video and audio input.

Figure 16. Universal Switcher Control program window

о To set up for audio follow switching (the output has the same audio and video

input selected), select the Audio and Video check boxes. To set up for audio breakaway switching (the output has different audio and video inputs selected), deselect the Audio or Video check box.

о To select an input, click the input button. о To set the input audio level (gain and attenuation), click the Gain/Att tab. о To manually adjust the level and peaking, click the Level/Peak tab. о To select or deselect auto switch mode, click the Auto Switch tab. о To set the output volume, click the Volume tab. о To set the RS-232 or audio deﬁnition for wire pair 3 and 6, click the RJ-45 tab. о To set the skew adjustments, click the Skew tab.

Contact Closure Remote Control

The Remote connector also provides a way to select an input to the switcher using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface. Figure 13 shows the contact closure pin assignments.

To select a different input number using a contact closure device, momentarily short the pin for the desired input number to logic ground (pin 5). To force one of the inputs to be always selected, leave the short to logic ground in place. The short overrides front panel input selections.
