Mounting the MLS 608 D Series Switchers

If the device is to be rack mounted, it may be easier to do so before cabling it, depending on the ease of access to the rear panel after mounting. Four rubber feet are included with the unit. Install the feet only if the unit is to be mounted on a tabletop (see “Tabletop placement” below).

Tabletop Placement

For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto the four corners of the bottom of the device.

UL Guidelines for Rack Mounted Devices

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of

the MLS 608 D Series switcher in a rack.

Elevated operating ambient temperature — If 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 device in an environment compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) speciﬁed by

Extron.

Reduced air ﬂow — Install the equipment in a rack so that the amount of air ﬂow required for safe operation of the equipment is not compromised.

Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.

Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Rack Mounting

To rack mount the switcher, insert screws into the brackets and attach them to the sides of the switcher. Then secure it to the the rack (see ﬁgure below).

a Power input — Connect the standard IEC power cord from a 100 to 240 VAC, 50 Hz

or 60 Hz power source into this connector. The front panel control and input selection

buttons light in sequence during power-up.

b Inputs 1-3 — These three universal analog input ports (15-pin HD [VGA] connectors)

can be congured to accept RGB (RGBHV, RGBs), component (bi- or tri-level), S-video, or composite video signals. The default setting is for RGB. The table below shows the pinouts for each format type on the 15-pin HD (VGA) connector.

From these ports, the signals are passed through to the MPT output. The ports also

support RGB delay and EDID emulation.

z RGB delay — RGB delay mutes the video rst, then switches the sync signals, and

then switches the RGB video. This brief delay allows the display to adjust to the

new sync signal before displaying the picture, providing a glitch-free switch. The delay can be set using SIS commands or the DSP Conﬁgurator software using

the Video I/O workspace. RGB delay can be set from 0 to 5 seconds in 0.5-second

increments.

z EDID settings — EDIDs (resolution and refresh rates) for digital inputs can be

automatically assigned when connecting a display with a common resolution and

refresh rate. The user can assign a different EDID, for both analog and digital inputs, using the data from an EDID table. See the table on page 23 for EDID

settings.

The EDID can be manually assigned using SIS commands or via DSP Congurator. The default settings are 720p at 60 Hz for digital inputs, and 1024x768 at 60 Hz

for analog inputs.

MLS 608 D Series • Rear Panel Connections 8

c Buffered output — This buffered analog output is

Pins:

CONFIGURABLE ANALOG INPUTS

tied only to input 1 and is a direct pass-through from any video signal, such as composite, S-video, RGBs,

and YUV, that is present on input 1.

BUFFERED OUTPUT

Connect a local output to this 15-pin HD (VGA)

connector for a buffered analog output from input 1.

The set signal type is output on the VGA connector, however, for composite, S-video, RGBs, and YUV signals, break out cables are needed

when connecting a display.

d Input 4 — This port is used to input universal MTP video signals with mono audio

support from an MTP transmitter. The input accepts composite, S-video, component

(bi-level and tri-level), and RGB (RGBHV and RGBS) video signals, but does not support EDID emulation. When switching to this input, the incoming signal is passed to the MTP output. The MTP HDMI U R receiver auto-detects the incoming video signal and

outputs it on the appropriate video connector. The input supports level and peaking adjustment, setting the incoming signal to

appropriate levels. Skew adjustment is available with this input, compensating for up to 64 nanoseconds

of skew. Adjustments are made using DSP Conﬁgurator software or SIS commands. Settings are stored in the memory and recalled when the input is selected.

NOTE: • See the DSP Conﬁgurator Help File "Video Settings" section, or the

"SIS Programming and Control" section for method of skew adjustment.

• This port does not accept RS-232 commands from an MTP transmitter.

Connect to the transmitter by plugging a terminated CAT 5, 5e, or CAT 6 twisted pair

cable into these RJ-45 connectors. The T568A and T568B standard pinouts are shown below. Use the same standard at both ends of the cable.

f Analog MTP output (audio and video) — This output transmits signals from an

active analog input over CAT 5 cable to the MTP/HDMI U R receiver. It is also capable

of transmitting line level mono audio over the same cable as audio output 3.

The output also supports pre-peaking adjustment for optimizing video signals for long cable runs.

Skew adjustment is available on this ouput, compensating for up to 64 nanoseconds of skew. Adjustments are made using DSP Conﬁgurator software or SIS commands. Settings are stored in the memory and recalled when the input is selected.

Connect the MTP HDMI U R twisted pair receiver (supplied) for analog audio and

video output.

NOTES: • See the table on page 9 for pinout details.

• See the table on page 10 for output transmission distances.

g Digital Inputs 5-8 — These four HDMI inputs are HDMI 1.3 compatible and have the

following features:

z HDCP authentication – The MLS 608 D gives a status feedback if it detects any

of the following are valid:

z If a source is HDCP compliant z If a source has active video z If a display is HDCP compliant (only if connected input is encrypted)

If the source is HDCP compliant but the display is not, the MLS displays a green

screen at the output.

See "HDCP Compliance" within the "DSP Conﬁgurator" section, for the detailed

method of HDCP detection and operation.

z Digital input equalization — Each digital input has automatic equalization to

compensate for distance from the source to the input. This gives 1080p, 8-bit

color, with a maximum distance of 50 feet using Extron Pro Series HDMI cable.

NOTE: The transmission distance varies greatly depending on the signal

resolution, and on the type of cable, graphics card and display used in the system.

z Audio de-embedding — Each of the HDMI inputs de-embed 2-channel PCM

audio signals at 48 Hz only. Other audio signals are not de-embedded: the signal

will be muted at the DSP processor and audio will not be heard. The audio to be de-embeded is user selectable from either the existing embedded

digital audio or a local analog input. The default is digital audio.

Connect up to four digital HDMI and DVD-D inputs to the HDMI connectors g. Connect DVI-D sources using an

adapter cable and secure the connectors to the MLS 608 D using the LockIt™ bracket as follows:

1. Plug the HDMI cable into the panel connection.

2. Loosen the HDMI connection mounting screw

from the panel enough to allow the LockIt lacing bracket to be placed over it.

3. Place the LockIt lacing bracket on the screw

and against the HDMI connector, then tighten the screw to secure the bracket.

NOTES: • Transmission distance varies greatly depending on the signal resolution,

Crimped Connector

and the type of cable, graphics card and display used in the system.

• Shielded twisted pair cable provides added protection from outside interference and increases overall signal transmission distance.

Extron recommends using shielded twisted pair for optimal performance.

When using STP cable, terminate the cable as follows:

1. For each cable, peel back the cable shielding from the end of the cable 7/8 inch

[2.2 cm]) and fold it back.

Peel back shield and fold back.

Figure 6. Peeling Back the Cable Shielding

2. Cut away and discard the clear cellophane inner wrapper from the end of the

cable back to the folded-over cable shielding.

3. Peel the backing off the self-adhesive shielded aluminum tape and wrap it around

the folded-over cable shielding, slightly overlapping the beginning of the tape.

Aluminum Tape

Wrap tape around folded foil shielding with a slight overlap. Cut and save the excess tape for other connectors.

Figure 7. Wrapping the Shielded Tape

4. Cut the unused portion of the shielded tape and retain for further uses.

5. Feed each individual wire into the appropriate slot of the RJ-45 connector and

crimp the cable in the normal manner, folding the tangs at the end of the connector over the shielded tape.

Power connection — Connect the 2-pole 3.5 millimeter captive screw connector

from the 12 VDC, 1.0 A external power supply (provided) to this receptacle  on the rear panel. Ensure the connections have the correct polarity.

CAUTION: Always use a power supply supplied or specied 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.

Alternatively, connect to the 2-pole power connector on the MLS 608 D (see e

See the ﬁgure at right showing how to wire the connector.

on page 10).

CAUTIONS: 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 identify the power cord negative lead. The length of the exposed (stripped) copper wires is important. The ideal length is 3/16 inch (5 mm). Longer bared wires can short together. Shorter wires are not as secure in the connectors 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.

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

is plugged in. Remove power before wiring.

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.

When power is applied the front panel power LED lights.

MLS 608 D Series • Rear Panel Connections 18

Power Save Mode

Power Save mode is a feature on the MLS 608 D that will help conserve energy and reduce costs by placing the unit into a standby state. The switcher does not have an auto-power down feature (like the one used on the XPA 1002, for example), and can only be placed into the standby state via an SIS command. Sending the SIS command E1PSAV] turns on the power save mode.

When Power Save mode is enabled the switcher draws less than 4 watts, the front panel buttons and volume indicators are off, and the front panel power LED is amber, indicating

that the switcher is in the standby state.

The switcher can be “woken” up with an SIS command (E0PSAV]), or by pressing any front panel button or turning any encoder/knob. This reverts the switcher to the normal mode (power save off).

When in its normal state, the front panel buttons and volume indicators are lit and the power LED indicator is green.

NOTES: • If the switcher is in the standby state, and power is re-cycled on the unit,

it powers back up into the normal state, and not into the standby state.

• The switcher is not ENERGY STAR® qualiﬁed.

NOTES: • After a Mode 1 reset, update the rmware to the latest version.

DO NOT use the factory ﬁrmware resulting from the reset. Factory ﬁrmware must be re-uploaded if that is the version to be used.

• If you do not want to update the rmware, recycling the power reinstates the ﬁrmware version used before the Mode 1 reset.

MLS 608 D Series • Operation 20

Mode 5 — Reset the MLS 608 D to factory default (except ﬁrmware).

To reset the device to factory defaults (with the exception of the ﬁrmware), press and

hold in the reset button for approximately 9 seconds, until the LED blinks three times

(once at 3 seconds, once at 6 seconds, and once again at 9 seconds).

Release and within 1 second press the reset button once (<1 second).

NOTES: Nothing will happen if the momentary press is not made within 1 second.

This reset is equivalent to the SIS reset command EZQQQ.

c Front panel conﬁguration port — This port is used for MLS 608 D conﬁguration

and ﬁrmware upgrades.

Connect a computer to this mini USB port (cable not supplied) for conguration and

control using DSP Conﬁgurator software or SIS commands.

For ﬁrmware upgrades use the Firmware Loader Software. See "Firmware

Upgrades" later in this chapter for method.

d Source selection buttons — These eight buttons are used to select between any

of the eight inputs. The button lights amber when selected, and can be conﬁgured to show an input number, icon, or device name as desired using the supplied button labels.

Alternatively, these buttons can be labeled as required. See the “Button Labeling”

section for details.

e Program volume adjustment knob — This knob is assigned to Group Master 1,

which controls program outputs 1, 3, and 4 (MA and SA models only), post switcher,

pre-mic mixing programs. By default it controls the volume of the three program

outputs together.

NOTE: By default, program output 2 has a ﬁxed output level.

Use this volume adjustment knob to set or adjust the program output volume (attenuation, from -100 dB to 0 dB) as desired. The LEDs indicate the overall percentage level for Group Master 1; the volume level being all off (0%) at -100 dB through to all on (100%) at -4 to 0 dB. Any level changes made do not affect the mic

audio.

Rotate the knob clockwise to increase volume, counter-clockwise to decrease volume. The

corresponding LEDS light as the knob is rotated. See the table at right for LED/dB values.

Volume control of Group 1 individual program

outputs (programs 1, 3, or 4) can be made

through DSP Congurator software. Group 1

can be reconﬁgured through DSP Conﬁgurator software.

Use this knob to set or adjust the two MIC volumes as desired from -100 dB to 0 dB. The LEDs indicate the volume level. See the table at above right for LED/dB values.

Using EDIDs

Rotate the knob clockwise to increase volume, counter-clockwise to decrease volume.

The corresponding LEDS light as the knob is rotated.

Volume control of Group 2 individual mic levels (mic pre-mixer gains 1 and 2) can be

made through DSP Conﬁgurator software.

Group 2 can be recongured through DSP Congurator software.

NOTE: The program and mic volume settings and adjustments can also be made

using Extron DSP Congurator program or by Simple Instruction Set (SIS)

commands. See the “Using the DSP Conﬁgurator Software”section and the “SIS Programming and Control” section for details.

EDID Minder

This pre-installed feature ensures that all sources power up properly and reliably

output content for display. EDIDs (resolution and refresh rates) for digital inputs can be

automatically assigned when connecting a display with a common resolution and refresh

rate. For both analog and digital, the user can assign a different EDID from an EDID table.

A different EDID (as given in the table on the next page), can be manually assigned using

SIS commands or via DSP Conﬁgurator.

For the MLS 608 D units, the default settings are 1024x768 at 60 Hz for analog inputs, and 720p at 60 Hz, 2-channel PCM audio for digital inputs.

NOTES: • To work with the EDID Minder, update the EDID table, and import or export

EDID data, the MLS 608 D must be connected in Live mode.

Automatic EDID Mode (digital output only)

In this mode, if no displays are connected, the default EDID (720p @ 60 Hz, with 2-channel PCM audio support) is present as the native resolution at each HDMI input. When a display is connected to the digital output, the EDID of that display is automatically read and stored, and the default EDID is overwritten for each HDMI input. The reading and storage of the new data is triggered by the Hot Plug Detect signal (HPD) the moment the

display is detected. The stored data remains present even after the display is removed.

When a display with a different EDID is connected, or a user assigned EDID is chosen, the HDP triggers a new data overwrite for all the digital inputs.

NOTE: The Hot Plug Detect (HDP) signal triggers on all digital inputs simultaneously

whenever a stored EDID is updated regardless whether it is by an automatic or user assigned EDID. This allows the source to restart the EDID read and verify the HDCP authentication process.

User Assigned EDID Mode

In this mode the EDIDs can be chosen (by the user) from the table and can be assigned to each input group (VGA and HDMI). Within this mode, the user EDID can be factory loaded (see EDID table on page 22) or user loaded. For user loaded EDIDs these can be either analog or digital EDIDs.

User Loaded EDID – Analog

The EDID of a display connected to the local (VGA) Buffered Output connector (see c on

page 9) can be read and stored to the analog User Loaded spaces 1 or 2 (SIS values 49

and 50, see gure 14). This analog output EDID can later be recalled as the user assigned analog EDID for inputs 1through 3.

To save the analog output EDID information to the User 1 or User 2 location in the EDID table:

1. Connect the display to the local analog output on the MLS 608 D Series switcher.

2. Start DSP Conﬁgurator, if it is not running already, and connect to the device in the

Live mode.

3. From the Tools menu, select Configure EDID to open the EDID Conguration

dialog box.

Figure 14. EDID Conﬁguration Dialog Box

4. In the Save Analog Output to User Loaded IDs section, click the User 1 or

User 2 button. This saves the EDID information from the analog output to the

associated location (User 1 or User 2). The saved resolutions and refresh rates are now available as User 1 and User 2 options in the Inputs 1-3 section.
