Compatibility with Attached Devices

The following sections provide guidelines regarding compatibility with source and display devices.

EDID compatibility

Display devices communicate with source devices using Extended Display Identification Data (EDID), a Video Electronics Standards Association (VESA) standard data format that contains basic information about a monitor and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings , frequency range limits and character strings for the monitor name and serial number.

EDID information stored in a display device is passed to the MPX receiver across the video cable through a digital path called the Display Data Channel (DDC). The receiver forwards this information to the transmitter across the media LAN. The transmitter, in turn, passes the EDID information to the source device, thus allowing plug-and-play functionality among display and source devices.

An MPX extender group has a single primary receiver, which has special responsibilities regarding serial, IR, and video functionality. Regarding video, only the primary receiver passes its EDID information back to the transmitter. Thus, the display device attached to the primary receiver should be representative of the devices attached to other receivers.

The MPX transmitter is pre-configured with default EDID information, which indicates support only for 640x480 resolution at 60Hz. This EDID will be passed to a source device in lieu of information received from MPX receivers. As the transmitter learns about the attached display devices through receiver bindings, it uses the information to create a more meaningful EDID string, referred to as the active EDID string. The process occurs as follows:

• Initially, the active EDID string is blank

• When a receiver binding occurs, if the receiver is not the primary and if the active EDID string is blank, then the transmitter will merge the received and default EDID strings such that the resulting string represents the common features supported by both devices. This new string will be stored as the active EDID and will be reported to the source device.

• When the primary receiver binds with the transmitter for the first time, the merge process will be repeated using the default and primary EDID strings.

• When bindings are established with subsequent receivers, no action is taken.

• If a different receiver is selected as the primary via the transmitter’s web interface, then the merge process will be repeated when a new primary EDID string is received.

• If the primary display device is replaced with a different model, then the receiver will report the information to the transmitter and a merge process will take place.

NOTE: A blank screen may occur as EDID changes are being processed.

10 MPX Extender Installer/User Guide

HDCP compatibility

High-Bandwidth Digital Content Protection (HDCP) protects video content as it travels across DVI-D or HDMI connections. Compliant devices do not allow users to make copies of protected content and must effectively frustrate non-compliant attempts to view protected content.

For example, protected digital video content must be restricted to DVD quality when viewed on non-HDCP display devices. Likewise, digital audio content is restricted to DAT quali ty on nonHDCP digital audio output devices.

The following procedures ensure security for protected high definition content:

• Authentication: To identify non-compliant display devices

• Encryption: To prevent eavesdropping of protected content

• Key revocation: To block devices manufactured by vendors in violation of license agreements from receiving HD content

MPX extenders serve as a repeater between compliant HDCP source and display devices. When all display devices and the source device are HDCP compliant, high definition content will display normally. HDCP special cases are handled as follows:

• When a new display device is added to the extension network, its key will be passed to the source device for validation. The MPX transmitter will stop transmission of protected content until the new display device is validated by the source device. The duration of this process may last up to 15 seconds. The session will continue automatically upon successful

authentication.

• In the event that a revoked key is detected, the session will terminate to all display devices. In this case, the user will need to determine which display device is presenting a revoked key and remove it from the extension network. Once removed, the MPX transm it ter must be rebooted to flush the key from its memory. At that point, the session should resume normal ly to all compliant display devices.

• In the event that a display does not support HDCP, then the MPX receiver will not send protected content to that display device. Unprotected analog audio will be processed normally by the MPX receiver.

• The MPX receiver supports connection to compliant display devices. Connection to devices such as an HDCP compliant switch, which may present multiple keys, is not supported. Should this occur, the MPX receiver will refrain from sending video content to the device. Other receivers in the extension network will not be affected.

Rack Mount Safety Considerations

Before installing the appliance and other components in the rack (if not already installed), stabilize the rack in a permanent location. Install the equipment starting at the bottom of the rack, then work to the top. Avoid uneven loading or overloading of racks.

• Elevated ambient temperature: In a closed rack assembly , the operation temperature of the rack environment can be greater than room ambient. Use care not to exceed the rated maximum ambient temperature of the unit.

• Reduced air flow: Carefully install the equipment in a rack so that an adequate amount of airflow is maintained for safe operation of the equipment.

• Mechanical loading: Avoid a potentially hazardous condition caused by uneven mechanical loading by carefully mounting the equipment in the rack.

• Circuit overloading: Consider the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Observe equipment nameplate ratings for maximum current.

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

MPX1500 transmitter overview

The MPX1500 transmitter is a second-generation transmitter that is designed with minimal footprint in mind. To accomplish this goal, the media module has been replaced by a single DVI-I duallink media input port and the front panel display have been replaced by LEDs. Although similar in functionality to the MPX1000 transmitter, the MPX1500 transmitter requires slightly different configuration due to the multi-purpose media input port and lack of button panel interface.

The front panel of the MPX1500 transmitter and receivers are identical. Refer to MPX1500 receiver overview on page 19 for an overview of the front panel.

MPX1000 Media Modules

Two types of media modules exist for MPX1000 extenders, as follows:

NOTE: Media modules are not required for MPX1500 extenders.

• Input media modules for MPX1000 transmitters

• Output media modules for MPX1000 receivers (shown below) Media received from a source device at the input module of the transmitter is processed and passed

to bound receivers where it is properly converted and sent to display devices through the output media module. Media modules must be installed in all MPX1000 extenders for proper operation.

NOTE: With your MPX1000 unit you have received two snap-on ferrites. If you are using the analog audio (RCA Jacks) these ferrites should be applied to each end of the cables. Apply the ferrites approximately one inch from the cable ends. One ferrite goes around both cables.

HDMI media module

The HDMI media module supports both HDMI and DVI-D signalling. HDMI functionality includes support for HDMI video, embedded audio, EDID passing, digital rights management (HDCP) and device control (CEC). DVI-D functionality includes video, external audio, EDID passing and HDCP. DVI-D connectivity requires an DVI-HDMI adapter, which is included with the media module.

Supported resolutions are defined in MPX1000T HDMI Input Module Product Sp ecifications on page 85.

HD15 media module

The HD15 media module is intended for use with analog computer graphics and video. The module supports industry-standard VGA and component video devices. An optional modular adapter is required for component video: HD15-BNC3. Component video is supported only by the input (transmitter) media module. Thus, the extender system is able to input component video for output on HDMI, VGA, or DVI-D display devices.

The HD15 media module passes EDID information in addition to video signals, thus allowing plugand-play operation among source and display devices.

Supported resolutions are defined in MPX1000T HD15 (VGA) Input Module Product Specifications on page 87.

Cross conversion

MPX extenders are able to pass both interlaced and progressive video formats but they do not support interlacing or deinterlacing. It is possible, however, to cross-convert a signal from one video format to another through the extension network. For example, RGBHV video received by transmitter with an HD15 media module is able to output to an HDMI display device by receiver equipped with an HDMI media module. In fact, the receiver could output either HDMI or DVI-D signalling as long as the resolution remained the same on both sides of the network; the system does not provide video scaling. An HDMI source, however, may not be output to a VGA display device. This is prohibited due to compliance with digital rights

management.

Installation

Getting Ready

To begin installing your Emerge MPX extenders, do the following:

• Take proper precautions against antistatic discharge.

• Remove your MPX transmitter, receivers, antennas and media modules (for MPX1000 transmitters or receivers) from their boxes.

• Refer to the kit contents list to ensure that you have all the items necessary for your

installation. See Kit Contents on page 100 for a complete list of product content s.

• Place the units on a stable working surface. T o prevent radio rec eivers from being over-driven, allow a distance of three feet between adjacent units.

• Connect antennas to the extenders. Fold the antennas inward while the extenders are in close proximity to each other. Excessive signal strength may cause data loss and

retransmission.

• Ensure that all units are turned off at this time.

Installing MPX1000 Media Modules

For MPX1500 transmitters and receivers, skip to the next section. MPX1000MT media modules provide media input ports and are intended for use with MPX1000

transmitters. MPX1000MR media modules provide media output ports and are intended for use with MPX1000 receivers.

NOTE: Proper electrostatic discharge (ESD) protection should be used at all times.

To install a module into your transmitter or receiver:

1. Align the edges of the media module with the open media module slot on the rear of the unit.

2. Slide the media module into the transmitter or receiver(s), until it is fully seated.

3. Fasten the media module into the unit using the provided screws. Do not over tighten or the screw may be damaged.

Transmitter Configuration

The transmitter can be configured by using an intuitive web interface. The following steps guide you through this process.

LAN settings

To configure transmitter control LAN (L1) settings:

1. For MPX1000 transmitters, attach the AC line cord and turn on your transmitter. The green LED should illuminate to indicate presence of power. For MPX1500 transmitters, attach the AC line cord to the power supply and connect the DC power to the transmitter.

2. Wait for the initialization sequence to complete: a. Fo r MPX1000 transmitters: An Avocent logo will appear on the front panel disp lay. b. For MPX1500 transmitters: Two green LEDs will alternate and all other LEDs will

turn

off.

3. Using an Ethernet crossover cable or hub, connect a browser client to the control LAN port (labeled L1) on the rear of the transmitter.

4. The default IP address for L1 of the transmitter is 192.168.1.1 with a subnet mask of

255.255.255.0. This may be changed using either the 5-b utton front-panel display or the web interface. Refer to

Configure control LAN on page 63 for detailed instructions regarding the

MPX1000 transmitter ’s front-panel display.

5. Change the IP address of the browser client computer so it can directly access the transmitter, for example 192.168.1.20, if necessary.

6. Launch a browser session to the IP address of the transmitter to invoke its web configuration

utility via L1, the control LAN port.

7. Leave the username blank and type the default password, which is Admin (case sensitive).

8. If the unit has not yet been configured, you will be prompted to enter a country code. This code is used by the product to establish allowable settings for wireless bands, channels and power

limits.

9. If desired, select the password page to change the system password. See Change Password on page 41.

10. For MPX1000 transmitters, you may configure the IP address of the L1 control LAN port via the front panel as described in

Configure control LAN on page 63. For all MPX transmitters,

you may configure the IP address of the L1 control LAN port using the web interface. Figure

3.1 illustrates the network settings dialog box. To alter the settings, select the Control LAN Settings page and set the parameters as follows:

a. Type the IP address for L1 (control LAN) to match the network on which it will be placed.

Use this address for subsequent browser connections. Do not use the following reserved IP addresses: 0.0.0.0, 192.168.1.10, 192.168.1.1, 192.168.1.2, 192.168.10.xxx or

192.168.11.xxx.

Chapter 3: Installation 27

b. Type the subnet mask for L1. c. Type the gateway address for L1, or 0.0.0.0 if there is no gateway.

11. The LAN Speed / Duplex setting allows you manually select 10 or 100Mbps LAN speed and full or half duplex operation. By default, these settings will be automatically negotiated with your switch or hub. To ensure interoperability, compatible settings must be selected on the Ethernet switch and MPX extenders.

12. Apply the changes.

NOTE: Once you change the IP address of a unit, the browser session will terminate. Your browser session must be re-established using the new address of the unit.

Figure 3.1: Control LAN Settings

To configure transmitter source device settings:

The MPX1500 transmitter features a DVI-I dual-link media input port that supports DVI-D, HDMI, DVI-A, RGBHV, and component video.

NOTE: Composite and S-video may also be supported depending upon the firmware revision of your transmitter.

To properly detect and process a video stream from a source device, the transmitter must be properly configured. The Source Device Settings page is used to configure the transmitter for the type of video to be received.

Figure 3.2: Transmitter Source Device Settings

28 MPX Extender Installer/User Guide

1. Within the T ransmitter Menu, select the Source Device Settings page. Figure 3.2 illustrates the available settings.

2. The default setting, Plug-and-Play, allows the transmitter to auto-detect the video format from the video cable or adapter that is attached to the transmitter. Auto-detection relies upon the state of ID bits that the transmitter reads from the attached video cable. When using Avocent cables or adapters, the transmitter will properly sense the type of source device. Use of thirdparty video cables will cause the transmitter to sense the cable type as DVI-D/HDMI. Select your source device type as follows:

a. DVI-D/HDMI: Plug-and-Play will properly detect DVI/HDMI source devices when using

third-party cables or adapters. You may also use the optional DVI-HDMI/CEC adapter that is available from

Avocent.

b. RGBHV: Plug-and-play will properly sense an RGBHV source device only if you use the

DVI-HD15F adapter that was provided with your transmitter. This adapter may be used with third-party HD15-to-HD15 video cables or with HD15-to-DVI-A cables. For RGBHV source devices, place this adapter onto the transmitter at this time. Should you decide to not use the supplied DVI-HD15F adapter, then select Manual (VGA) from the drop down list at this time.

c. YPbPr: Plug-and-play will properly sense a YPbPr source device only if you use the

optional Avocent component video cable, DVI-BNC3, with your transmitter. Attach this cable onto the transmitter at this time. Otherwise, to use third-party cables, select Manual (Component) from the drop-down list at this time.

d. CV and YC: Plug-and-play will properly sense a composite video (CV) or S-Video (YC)

source device only if you use the optional Avocent component video cable, DVI-YCV, with your transmitter. Attach this cable onto the transmitter at this time. Otherwise, to use third-party cables, select Manual (Composite) or Manual (S-Video) as appropriate from the drop-down list at this time.

To configure transmitter system settings: (Optional)

1. Within the Transmitter Menu, select the System Settings page.

2. Type a friendly name into the Device Name text box. This will cause the name to be displayed throughout the web interface as means to identify the transmitter.

3. The HTTPS Required setting allow you to explicitly set HTTPS as the transport protocol for access to the web interface. Should you do so, it will be necessary to install a certificate from the MPX extender onto your browser client. HTTPS ensures encryption of all web content. If this setting is disabled, you may obtain a secure web session with the transmitter by launching an https session rather than an http session from your browser client.

4. For MPX1000 transmitters only, you may disable the ability to set the IP address of the transmitter via the front panel (five button) interface. By default, this capability is enabled.

5. The Remote Console feature allows for centralized control of the MPX extenders that are deployed at remote locations. Contact Avocent technical support before you enable this

feature.

Chapter 3: Installation 29

6. Apply the changes.

Figure 3.3: System Settings

Validating media LAN connectivity

Media session data (audio, video, and control information) is transferred from an MPX transmitter to bound receivers either through the wireless LAN interface or the L2 wired LAN interface. By default, MPX transmitters are configured for wireless operation. MPX receivers are configured neither for wired or wireless operation, rather they search for an active transmitter first on their wired and then on their wireless media LAN interfaces. The following sections will guide you through a quick test of the wireless and wired modes of operation.

Wired Media LAN (L2) setup (Optional)

Perform the following steps if you wish to use MPX extenders in a wired mode of operation.

To set up a wired media LAN:

1. Interconnect the media LAN ports of the MPX transmitter and all receivers using standard 100Mbps Ethernet hubs or switches and UTP cabling.

NOTE: Wired connection should be made to the L2 of MPX1000 transmitters to the L2 port of MPX1000 receivers and to the LAN port, as indicated by the LAN symbol, on MPX1500 receivers.

2. Using your browser client, navigate to the Media LAN Settings page on the MPX transmitter. This web page is illustrated in

Figure 4.3 on page 49.

3. Select the radio button that enables wired operation.

NOTE: The IP address of MPX receiver’s media LAN port is dynamically assigned by its transmitter at bind time. This process is similar to DHCP.

4. Although it is not possible to explicitly configure the IP address of the media LAN port of MPX receivers or transmitters, it is possible for 4 MPX transmitters and bound receivers to

30 MPX Extender Installer/User Guide

share a single wired extension network. Skip to the next step if you are not planning to install multiple transmitters on the same wired media LAN.

You may place more than one transmitter on a wired media LAN. To do so, select a unique Transmitter Number from the pull-down menu on the media LAN Settings web page.

NOTE: To allow multiple groupings of transmitters and receivers to coexist on a shared wired media LAN, each transmitter and its group of receivers must have a unique set of IP addresses.The Transmitter Number setting is used to select a unique base address for a transmitter and its associated

receivers. When placing multiple transmitters on a wired media LAN, it is necessary budget the bandwidth available to each transmitter to avoid excessive contention. The total video data rate across all transmitters should not exceed 60Mbps. Refer to Transmitter tuning parameters on page 43 for more information.

NOTE: Media LAN traffic is timestamped and latency sensitive by nature. For this reason, media LAN IP addresses are not routable. A wired media LAN may be interconnected using industry-standard Ethernet cables, hubs and switches. VLAN capable switches may also be used. Extended distance may be accomplished via fiber-based inter-switch links. In all cases, the media LAN must comprise a single subnet. It is not recommended to share the media LAN with other devices.

5. Apply the change.

Dynamic binding

After power up initialization, MPX receivers begin to search both wired and wireless media LAN interfaces for an accessible MPX transmitter. By default, an MPX transmitter accepts bind requests from 8 receivers. Bound receivers are listed in the transmitter’s web interface and on its front panel

display.

To validate your media LAN and bindings:

1. Plug all receiver line cords into the AC mains and power up your receivers.

2. Wait for the LEDs on all units to bind with the transmitter: the two green LEDs will cease to

alternate. This indicates that the receivers have successfully initialized and bound with the

transmitter.

3. Launch a browser session to the transmitter’s web utility and select Bindings in the

transmitter

menu.

4. Scroll to the bottom of the Bindings page and verify that all active receivers are listed (by

MAC address) within the Detected Receivers table.

Figure 3.4 on page 32 illustrates this table. If a receiver is not listed, verify proper LAN connectivity or power state of the receiver. If the receiver is not detected and your transmitter is configured for wireless operation, you may need to adjust the transmitter power setting, refer to

wireless transmission power settings on

page 48.

Setting explicit receiver bindings (Suggested)

By default, a transmitter honors requests from any receiver that requests binding. You may, however, configure a transmitter to honor bind requests only from a list of specific receivers.

Chapter 3: Installation 31

Requests from non-selected receivers will be rejected by the transmitter. This feature is referred to as explicit bindings.

Explicit bindings offer the following benefits:

• Loss of connection with dynamically bound receivers is not treated as an error condition

by the transmitter. Explicitly bound receivers, however, will be flagged as non-responsive should they drop connection with the transmitter.

• Explicit bindings allow for the selection of a Primary Receiver.

NOTE: It is necessary to establish a primary receiver to establish bi-directional serial and IR communications. Further, the Primary Receiver may be used to establish a particular display device as the source for EDID information. Without a primary receiver, EDID information will be accepted from the first receiver that connects to a transmitter, which may result in seemingly random behavior if the various display devices offer different EDID information.

• Multi-transmitter configurations require explicit pairings of receivers to transmitters.

The transmitter’s Bindings page contains separate tables for detected receivers and configured receivers. In addition, there is a global setting that enables automatic binding of detected receivers.

The Detected Receivers table contains an entry for each receiver that has discovered the transmitter and requested binding. Each entry provides the MAC address and bind status of the receiver. A check box is provided for you to add detected receivers to the Configured Receivers table. The Configured Receivers table provides explicit controls for receiver binding. A bound receiver participates in media sessions with the transmitter. Explicitly unbound receivers may be bound by a different

transmitter.

The global option, labeled Automatically Bind Detected Receivers, is used to indicate whether or not receiver bind requests are automatically granted.

NOTE: Automatic binding results in a dynamic extension network in which receivers bind and unbind as they are turned on and off. Although simple to establish, dynamic extension networks lack a primary receiver, which prevents the transmission of bi-directional serial and IR data.

To establish explicit receiver bindings:

1. Within the Detected Receivers table, select the Add to Configured Receivers checkbox next to each detected receiver.

Figure 3.4 on page 32 illustrates the Detected Receivers table.

2. Optional: You may manually enter a receiver’s MAC address. MAC address labels are affixed to the bottom of an MPX receiver .

3. Optional: Configure the Automatically Bind Detected Receivers setting using drop-down list. If enabled, the transmitter will automatically bind all detected receivers detected that are not explicitly disabled for binding in the Configured Receivers table.

4. Apply the changes.

32 MPX Extender Installer/User Guide

5. For each receiver that is intended to receive media from this transmitter, set the Bind Allowed checkbox in the Configured Receivers table. The remaining receivers may be bound to a different transmitter.

Figure 3.4 on page 32 illustrates the Configured Receivers table.

6. Click the Primary radio button to assign one unit as the Primary receiver for bi-directional exchange of IR and serial data and reception of EDID information.

7. Suggested: Set the Automatically Bind Detected Receivers pull-down menu to Disabled.

8. Apply the changes.

Figure 3.4: Bindings Page

Firmware Version Checking

Select the Version Information web page on the transmitter. Make note of the firmware version of the transmitter and each bound receiver. All units should be at revision 1.2.1.x or greater. Visit the Avocent web site at www.avocent.com and review the available upgrades. Should you decide to upgrade your units, see

Upgrading MPX Firmware on page 93 for detailed instructions.

Receiver Configuration

Accessing your receiver’s web interface

The on-board web interface of an MPX receiver may be accessed indirectly through the control LAN port (L1) of the transmitter or directly via the control LAN port of the receiver itself.

Chapter 3: Installation 33

NOTE: MPX1000 receivers feature a dedicated control LAN port, which is labelled L1. MPX1500 receivers have

a single LAN port that serves the combined functions of control LAN and media LAN. The combined LAN port on the MPX1500 receiver is programmed with two unique IP addresses, one for each function.

By default, the transmitter forwards web traffic between its control LAN (L1) port and its media LAN (L2) port or wireless LAN interface (whichever is active). Thus, no setup of cabling is required to access the web interface of any bound MPX receiver.

Hypertext links to active receivers are displayed at the bottom of the Transmitter Menu. Receivers are identified by their MAC address; however, once configured, friendly names will be displayed. A receiver’s web interface may be accessed by launching its link in the Active Receivers list. The receivers web interface will provide a hyperlink back to the

transmitter.

Should you wish to establish a dedicated wired control LAN for web access to MPX transmitters and receivers, the following section will guide you through the process.

MPX1500 receiver display device settings

For MPX1000 receivers, please skip to the next section. The MPX1500 receiver features a DVI-I dual-link media input port that supports DVI-D, HDMI,

DVI-A, RGBHV, and component video.

NOTE: Composite and S-Video may also be supported depending upon the firmware revision of your receiver.

The Display Device Settings page provides control over two functions of the MPX1500 receiver:

1. The page allows you to configure the receiver so it can identify the correct type of video to be output to the attached display device.

2. The page allows you to explicitly control the generation and management EDID information.

Figure 3.5: MPX1500 Receiver Display Device Settings

To configure MPX1500 receiver display device settings:

1. Using a browser client, access the web interface of the MPX receiver either directly or via the transmitter web interface.

2. From the Receiver Menu, select the Display Device Settings page. Figure 3.5 illustrates the available settings.

3. The default setting, Plug-and-Play , allows the receiver to auto-detect the video format from the video cable or adapter that is attached to the receiver. Auto-detection relies upon the state of

34 MPX Extender Installer/User Guide

ID bits that the receiver reads from the attached video cable. When using Avocent cables or adapters, the receiver will always properly sense the type of source device. The receiver is also able work properly with directly-attached third-party DVI-D/HDMI or RGBHV video cables. Select your display device type as follows:

a. DVI-D /HDMI: Plug-and-Play will properly detect DVI/HDMI display devices when

using third-party cables or adapters. You may also use the optional DVI-HDMI/CEC adapter that is available from

Avocent. The MPX1500 receiver is not able to generate

custom DVI-D/HDMI EDID information.

b. RGBHV: Plug-and-play will work properly with directly attached third-party RGBHV

cables. The cables may be HD15-to-HD15 or HD15-to-DVI-A. If your display device is not DDC2B compatible or if you wish explicit control over the resolutions available to the source device, then select Manual (VGA) from the drop down list at this time and select the resolutions that you wish to allow. Be careful to select only those resolutions that are supported by your display device. It is only necessary to configure custom EDID (resolutions) on receivers that may act as a primary receiver. The setting has no affect on other receivers.

c. YPbPr: Select Manual (Compon ent) from the drop-down list at this time and select the

resolutions that you wish to allow. Be careful to select only those resolutions that are supported by your display

device. When configured in this manner, the receiver will

emulate a DDC2B-compliant source device.

NOTE: An MPX1500 receiver will not request video data from a transmitter unless one or more resolutions are selected within the Manual (Component) configuration page.

d. CV and YC: Plug-and-play will properly sense a composite video (CV) or S-Video (YC)

display device only if you use the optional Avocent component video cable, DVI-YCV, with your receiver. Attach this cable onto the receiver at this time. Otherwise, if you wish to use third-party cables, select Manual (S-Video/Composite) from the drop-down list at this time.

MPX1000 receiver display device settings

For MPX1500 receivers, please skip to the next section. The MPX1000 receiver is compatible with a digital input media module (MPX1000MR-HDMI)

that supports DVI-D and HDMI video and an analog input media module MPX1000MR-HD15) that supports RGBHV and component video. Because the MPX receiver is able to read a unique product ID from each module, it is not required to configure an MPX1000 receiver for digital or analog media. Thus, MPX1000 Display Device Settings page is provided to allow you with the ability to override the EDID information provided by an attached source device. You may wish to do so if your display device does not properly support the EDID function or to restrict the source device to specific resolutions.

Figure 3.6 illustrates the MPX1000 Display Device Settings page.

Chapter 3: Installation 35

NOTE: The MPX1000 Display Device Settings page is displayed only when an analog media module (HD15)

is installed.

Figure 3.6: MPX1000 Receiver Display Device Settings

To configure MPX1000 receiver display device settings:

1. Using a browser client, access the web interface of the MPX receiver either directly or via the transmitter web interface.

2. From the Receiver Menu, select the Display Device Settings page. Figure 3.6 illustrates the available settings.

3. By default, the Override Display Device Modes checkbox is de-selected. In this state, the receiver will poll the display device for EDID information and pass it to the MPX transmitter, which in turn will pass it to the source device. By selecting this checkbox, the receiver will cease to poll for EDID information and instead substitute self-generated EDID information based upon configuration settings provided on this web page.

This feature becomes useful when an attached display device does not provide valid EDID information or if a device such as a video scaler blocks the normal passing of EDID information from the display to the receiver. You may also find this feature useful should you wish to restrict the resolutions available to users of the source device.

To provide custom EDID settings: a. Select the Override Display Device Modes checkbox. This will cause a table of

resolutions to appear.

b. Select the resolutions that you would like to make available to the source device. Be sure

to select only those resolutions that are supported by the attached display device and do not de-select all resolutions.

c. Apply the changes.

MPX receiver control LAN (L1) settings (Optional)

To establish a dedicated wired control LAN for management of MPX extenders, it will be necessary to establish unique IP addresses for the control LAN ports (L1) of each receiver and transmitter to be placed on the shared LAN.

To establish a wired control LAN for MPX receivers:

1. Interconnect the control LAN ports of the MPX transmitter and all receivers using industrystandard 10/100Mbps Ethernet components.

2. Attach your browser client to the control LAN.

3. Turn on a single MPX receiver and leave all other receivers with default addresses turned off.

4. Launch a browser session to the default IP address of an MPX receiver, which is 192.168.1.2 with a subnet mask of 255.255.255.0.

5. If prompted, type the default password, which is Admin (case sensitive).

6. If the unit has not yet been configured, you will be prompted to enter a country code. The wireless radio is disabled until a country code is entered. In addition to enabling the radio, the country code will establish legal bands, channels, and power limits.

7. Within the receiver menu, select the Control LAN Settings page and set the parameters as

follows:

a. Enter the IP address of the control LAN to match the subnet on which it will be placed.

Use this address for subsequent browser connections. Do not use the following reserved IP addresses: 0.0.0.0, 192.168.1.10, 192.168.1.1, 192.168.1.2, 192.168.10.xxx or

192.168.11.xxx. b. Enter the control LAN subnet mask. c. Enter the control LAN gat eway address, or 0.0.0.0 if there is no gateway.

8. For MPX1000 receivers, you may manually select the LAN speed and duplex settings. To ensure interoperability, compatible settings must be selected on the Ethernet switch and MPX1000 extenders.

9. Apply the changes.

10. Label the unit with its new IP address.

11. Return to step 3 until all MPX receivers are configured with unique IP addresses.

Configure receiver system settings (Optional)

Although optional, it is recommended to configure each receiver with a friendly name. These names will be displayed within the web interface of the transmitter. Other system settings affect diagnostic splash screens and remote diagnostics.

To configure receiver system settings:

1. Using a browser client, access the web interface of the MPX receiver either directly or via the transmitter web interface.

Chapter 3: Installation 37

2. Within the Receiver Menu, launch the System Settings page.

3. Type a Device Name to associate a friendly name with the unit, such as “Front Lobby Display.” The device name may contain any combination of printable characters but it cannot exceed 127 characters. This name will be displayed for your convenience throughout the web interface. The name will also be displayed on the front panel of an MPX1000 transmitter.

4. The HTTPS Required setting allow you to explicitly set HTTPS as the transport protocol for access to the web interface. Should you do so, it will be necessary to install a certificate from the MPX extender onto your browser client. HTTPS ensures encryption of all web content. If this setting is disabled, you may obtain a secure web session with the transmitter by launching an https session rather than an http session from your browser client.

5. The Display Status Screens setting allows you enable and disable the display of status messages on the display device. Status messages include diagnostic information that may be useful during initial installation but may not be desired once units are deployed.

6. The Remote Console feature allows for centralized control of the MPX extenders that are deployed at remote locations. Contact Avocent technical support before you enable this

feature.

7. Apply the changes.

Multiple transmitter considerations

If there are multiple transmitters to which your receiver may bind, you may select a particular

transmitter.

NOTE: Binding consists of a procedure in which a receiver searches the wired LAN and then wireless frequencies for an MPX transmitter, which appears as an access point. When a transmitter is located, the receiver may ignore the transmitter or request binding. This parameter, when set, will cause the receiver to filter out all transmitters except for the one with the defined MAC address.

To select a specific receiver:

1. Browse to the Media LAN Settings of the receiver.

2. In the MAC Address of Transmitter field, enter the MAC address of the transmitter to which this receiver shall attempt to bind. The MAC Address may be displayed via the transmitter’s System Settings web page.

3. Apply the changes.

Configure receiver password (Optional)

Refer to Change Password on page 41 for detailed instructions.

Initiating A Media Session

Your MPX extension network is now ready for a media session. The following steps allow you to verify proper operation of your transmitter, receivers, establish an

Active EDID string at the MPX transmitter and test compatibility of your source and display devices through the extension network.

To establish your first media session across the extension network:

1. Turn of f your MPX transmitter and receivers.

2. Turn off your display devices.

3. Properly shut down off your source device if it is not already turned off at this time.

4. Attach your display device to the primary MPX receiver using an appropriate cable.

NOTE: If your display device does not support DDC2B or if a cable or video switching device prevents the normal flow of EDID information across the DDC bus, then refer to

Common Tuning Needs on page 75 for

additional information. Please do so before moving on to the next step.

5. Power on the display device.

6. Power on the primary MPX receiver.

NOTE: This power up sequence ensures that the display device is online when the MPX1000 receiver reads EDID information from the device.

7. Attach the source device to the MPX transmitter using an appropriate cable.

8. Turn on the MPX transmitter.

9. Wait for the MPX receiver to bind with the MPX transmitter, as previously described.

10. Power on your source device and activate as necessary to ensure flow of video data.

NOTE: This power up sequence ensures that proper EDID information is stored in the MPX transmitter before the source device attempts to read it. The order of power up sequencing is important only once, during initial configuration and setup. If it is necessary to replace a field-installed MPX transmitter with brand new unit, these same steps should be used to properly establish valid EDID information in the replacement unit.

11. Active video should appear on the display device attached to the MPX receiver within 30 seconds after the source device has completed initializing.

12. Additional receivers and display devices may now be added to the extension network.

Troubleshooting

If video fails to appear on your display device or if plug-and-play functionality is not functioning normally, see

Video Troubleshooting on page 74 for detailed troubleshooting proced ures.

Chapter 3: Installation 39

Transmitter and Receiver Placement

To find acceptable locations for your extenders:

1. Turn off all MPX extenders.

2. Turn off your source and display devices.

3. Place the transmitters and receivers in their desired locations without firmly mounting the

units.

4. Turn on the MPX extenders and raise antennas to their upright positions. Allow the units to initialize and bind.

5. Using the receiver signal strength indicator for guidance, position the units and antennas as needed to obtain optimal signal strength. If possible, seek to obtain three or more signal strength LEDs on the front of the receiver. Also, if possible, seek to obtain an average frame rate of 28 or greater on all receivers.

NOTE: Radio signals propagate outward from an omni-directional antenna in a disk-like perpendicular manner. A vertical antenna results in horizontal signal propagation. For this reason, it is best to start with transmitter and receiver antennas that are similarly oriented and aligned on the same horizontal or vertical plane. Vertical antennas result in horizontal emission. High gain antenna produce a narrowed yet stronger beam of radio waves than low gain antennas. Thus, it is more critical to position transmitters and receivers on the same plane when using high gain antennas.

NOTE: If transient obstructions, such as people, boxes or vehicles are anticipated during normal operation, then simulate these factors as best you can to observe their effect upon signal strength under real-world conditions.

If necessary, signal strength may be optimized as follows: a. Increase your transmitter power: See Table 4.3 on page 47 for more information.

b. Use specialized directional or high gain antennas: See Antenna Options on page 67 for

more information.

c. Use antenna extension cables to raise antennas above obstructions or pass antennas

through walls. Although extension cables allow for optimal antenna placement, they will attenuate signal strength. Thus, they should only be used when necessary and kept to a minimum length. Proper placement of your receiver, if possible, is preferable to use of extension cables. Never connect extension cables together as a means of extending antenna placement. Thus will result in excessive signal loss. See

Antenna Options on

page 67 for specific options and installation instructions .

d. Reposition your extenders: See Radio Consideratio ns on page 66 for

additional information. A slight movement of several inches may result in a noticeable increase of signal

strength.

e. Depending upon your environment, it might be advantageous to orient the antennas on

your transmitters and receivers such that one antenna on each unit is upward in a 12 O’clock position and the other antenna is perpendicular to it, in a 3 or 9 O’clock position. The vertical antenna will radiate on a horizontal plane and the horizontal antenna will

40 MPX Extender Installer/User Guide

radiate on a vertical plane. This may increase the benefit of antenna diversity by taking advantage of diverse reflections off of environmental objects such as walls, floors, desks, and

ceilings.

f. Use of lower frequency channels may slightly increase transmission distance and

wall

penetration. For maximum wall penetration, consider use of G band channels

and

antennas.

g. As a final optimization, you might want to compare receiver signal strength across all

frequencies. Starting at the lowest frequency, make note of the weakest signal strength reported by any receiver. Select the next frequency via the Media LAN Settings page on the transmitter. Allow the receivers to bind. Again, record the weakest signal strength reported by any receiver. Repeat this process until all channels have been tested. Set the transmitter for the channel that resulted in the strongest recorded signal strength. Take care to evaluate only those channels that are compatible with the antennas that you have selected. For example, do not test G band channels with UNII band antennas.

6. Once acceptable signal strength is attained, turn off the MPX transmitter and receivers.

7. Mount your MPX extenders securely without altering their orientation. See Appendix C, Mounting Options on page 79.

8. If your antennas will be subject to wind or other forces that might cause them to rotate out of position, then you might consider use of a few drops of silicon gel to lock the position of the

antenna.

9. Attach the video and audio source devices to the MPX transmitter.

NOTE: With your MPX1000 unit, you have received two snap-on ferrites. If you are using the analog audio (RCA Jacks) these ferrites should be applied to each end of the cables. Apply the ferrites approximately one inch from the cable ends. One ferrite goes around both cables.

10. Attach the video and audio sink devices to the MPX receiver(s).

11. Turn on your sink devices.

12. Turn on your MPX receivers.

13. Turn on your MPX transmitter and wait for the receivers to bind.

14. Turn on your source device.

15. Start a media stream from the source device to the MPX transmitter.

16. Using the browser client, launch to the transmitter’s Connection Status page. Figure 3.7 on page 41 illustrates the Bound Receiver Status table. Verify frame rate and signal strength for each of the bound receivers. The Media LAN Performance web page provides additional useful information. Make final adjustments, if necessary.

Chapter 3: Installation 41

Figure 3.7: Bound Receiver Status

Final Adjustments

Presentation of audio and video media should now be active at each display device, as if they were each individually attached to the source device. Inspect each display for signs of hesitation, color shift, audio loss, or other anomalies. Refer to

System Tuning on page 43 for additional information.

Extension of IR and Serial Data

After mounting your MPX extenders, continue with the next chapter if you intend to use the extension network to pass serial or IR control signals.

System Tuning

Transmitter tuning parameters

Controls provided on the Tuning Parameters web page, illustrated in Figure 4.1, allow you to fine tune the operation of your extension system.

To properly tune the video data rate settings, it is helpful to understand that the bandwidth capacity of the wireless media LAN is continually shifting rather than constant. Stated in another way, the capacity of the LAN to carry data expands and contracts as moving objects interact with the radio transmission. The majority of LAN bandwidth is required for transmission of video data, which consists of real-time video (data that is being sent for the first time) and retransmitted data. Under ideal conditions, the LAN is filled real-time data. Under adverse conditions, as may result from RF interference, receivers may capture only a portion of the real-time data. In response, those receivers may request retransmission of the missing data. The transmitter will attempt to service these retransmission requests even as even as real-time data is being sent to other receivers.

To ensure an acceptable video frame rate and image quality, the transmitter is able to dynamically detect shifting conditions and alter its processing of real-time and retransmitted data as needed to accommodate for these conditions. To allow increased headroom for retransmitted data, real-time data can be more highly compressed (within user-defined limits). Likewise, the amount of retransmitted can be metered within pre-defined bounds to prevent isolated obstructions from affecting non-obstructed receivers.

The default tuning parameter values are designed to maintain a reasonable balance between image quality and frame rate across all receivers. Based on the needs of your particular application, it may be of value to tune these parameters. The following table provides you with additional information.

44 MPX Extender Installer/User Guide

The transmitter offers basic and advanced settings. The basic settings are described in the following

table:

Table 4.1: Transmitter Tuning Parameters - Basic Settings

Setting Description

Wireless Video Data Rate These settings allow the MPX transmitter to dynamically adjust the

degree of compression applied to real-time video data. The actual data rate at any given time will fall between the maximum and minimum data rate values, unless the image requires less than minimum data rate (such as a screen that is mostly black or white).

High data rates consume more bandwidth and result in the sharpest possible image. Lower data rates result in a softened image that requires less bandwidth.

During moments of interference, there may be insufficient bandwidth for the transmitter to maintain 30 frames per second at the maximum data rate while servicing requests for lost data. The minimum data rate setting determines how the transmitter responds to this condition. Setting this value high will cause the transmitter to drop frames as needed to maintain the sharpest possible image. Setting this value low will cause the transmitter to soften images as needed to maintain the highest possible frame rate. High values may be preferable for still computer graphics. High values may be preferable for motion video.

Maximum rates for wireless media sessions include integer values up to 20 Mbps. Maximum rates for wired media sessions include integer values up to 40 Mbps.

Content Type The MPX transmitter supports two compression algorithms. One

algorithm is geared toward computer graphics. Office automation tools such as presentation or spreadsheet applications will benefit from this setting. The other compression algorithm is geared toward motion video. Cameras and digital video players will benefit from this algorithm. Select the algorithm that is best suited for your primary application.

Luma-Chroma This parameter affects the way in which the transmitter processes luma

and chroma information in the input video stream. By default, 67% of the output stream is dedicated to luma information and 33% of the output stream is dedicated to chroma information. This ratio is well suited for a combination of motion video and some computer graphics. For applications that are heavily slanted toward still graphic images with sharp edges, you may have better results by increasing luma to 80%. Experiment with the slider bar to find the settings that are best for your

application.

Retry Limit This parameter sets an upper bound on the percentage of available

media LAN bandwidth that a transmitter will allocate for servicing of retransmitted data.

Chapter 4: Additional Functions 45

Figure 4.1: Transmitter Tuning Parameters - Basic Settings

If you click on Show Default Values, the web page will be updated to display factory default values. To save these values, click on Apply.

If you click on More Settings, additional parameters will be displayed. These additional parameters allow you alter the ramp up and down rates. Under most conditions, these settings should not be required. Should the basic tuning parameters be insufficient to resolve issues in your environment, contact Avocent technical support for additional suggestions.

Receiver tuning parameters

The Tuning Parameter web page on MPX receivers, illustrated in Figure 4.2, allow fine adjustments to be made to audio and video signal timing. It is also possible to restrict the amount of retransmission data that a receiver will request.

46 MPX Extender Installer/User Guide

The following table provides an overview of receiver tuning parameters:

Figure 4.2: Receiver Tuning Parameters

Table 4.2: Receiver Tuning Parameters

Setting Description

Receiver Video Latency The MPX transmitter places a timestamp on audio and video data to

ensure proper lip-synch across all bound receivers. Thus audio and video output will be synchronized across all display devices as long as the devices themselves introduce equivalent latency prior to display. Introduction of scalers, converters or other active processing devices between the output of an MPX receiver and its associated display device may cause a noticeable video or audio lag when compared to other receivers. With this parameter, it is possible to mimic this delay on other receivers, thus bringing all display devices into synchronization.

Default value for this parameter is 200ms. This delay provides an elastic buffer of roughly 7 frames, allowing receivers to remain in lock step even if lost packets need to be retransmitted. Reducing receiver latency below the default of 200ms may compromise synchronization across receivers. However, in applications consisting of one or two receivers, it may be desirable to reduce this value if the primary application involves mousedriven presentations that are sensitive to latency. If choppy video occurs on one or more receivers, raise the value until smooth video is obtained.

Receiver Audio Latency

Receiver Retry Limit This parameter limits the amount of retransmitted data that a receiver is

able to request from a transmitter.

If you are fine tuning... Then choose...

choppy video for a wired or wireless connection

The Wireless Video Data Rate settings on the Tuning Parameters page of the transmitter.

Figure 4.1 on page 45 illustrates this web page.

Choppy video is the result of lost data. The receiver to continue to output the last fully-received frame until a complete new frame is received. This is not noticeable for a still image, such as a spreadsheet. This is particularly noticeable, however, for a motion video. Audio playback requires minimal bandwidth and typically plays smoothly, even when motion video is choppy.

To restore smooth video playback, adjust the minimum data rate setting downward as needed to obtain a constant frame rate of 24 fps or greater under adverse conditions. Lowering the minimum setting allows you to maintain constant frame rate by slightly softening the image during adverse media LAN conditions. As conditions improve, the transmitter will gradually raise the video data rate.

Retransmission requests may stem from a temporary signal blockage, such as a box being placed in front of the transmitter. Wireless channel contention may also cause data interference. If interference becomes chronic, you may want to consider antenna extension cables or selection of a different wireless channel to relieve the condition.

wireless channel contention resulting from other wireless

devices

Figure 4.3 illustrates this web page.

Channel contention arising from other devices operating in the same channel may cause excessive dropped video frames. Selection of an unused channel will resolve this issue.

Available channels may be selected from a drop-down list. The selected channel will be used by the transmitter and bound receivers. Once changed, the media session will drop and bound receivers will enter a search mode. After the transmitter is detected, the session will continue

normally.

wireless transmission power

settings

Maximum Transmit Power field on the Media LAN Settings page. This setting may be set separately for transmitters and receivers.

Figure 4.3

illustrates this web page.

The range of values at the transmitter is determined by the country code and wireless channel. The range of values at the receiver may be wider than the transmitter because the receiver is not explicitly configured for country code and wireless channel settings. Nonetheless, the receiver will not exceed legal power limits at any time. The Actual Antenna Power field of a receiver’s Connection Status page displays the receiver’s true radiated power level.

Lower settings allow transmitters to be placed more closely. This is useful when multiple video streams are required. Higher values allow for increased distances between transmitters and receivers. In addition, Avocent offers optional extended distance antennas for this purpose.

The default power setting may overdrive radio receivers when MPX transmitters and receivers are positioned in close proximity to each other, within ten feet or less, as might be the case during initial configuration and testing. Over-driven signals may result in lost frames or in extreme cases, in dropped connections. To avoid such errors, select the lowest setting that results in a stable, acceptable image. Remember to raise transmit power levels when extenders are placed in their final locations.

Depending upon environmental conditions, you may find it beneficial to configure receiver transmit power settings slightly lower than the transmitter. This will reduce contention among receivers and ensure that the transmitter has the most dominant signal.

Sharpness of computer

graphics

Luma Chroma Percentages and Content Type on the Tuning Parameters page of the transmitter.

Figure 4.1 on page 45 illustrates this web page.

The luma chroma setting affects the way in which the transmitter processes luma and chroma information in the input video stream. By default, 67% of the output stream is dedicated to luma information and 33% of the output stream is dedicated to chroma information. This ratio is well suited for a combination of motion video and some computer graphics. For applications that are heavily slanted toward still graphic images with sharp edges, you may have better results by increasing luma to 80%. Experiment with the slider bar to find the settings that are best for your

application.

available to the device attached to its serial port. Serial data is passed in real-time and is not buffered for subsequent reading.

Serial passthrough modes are enabled via the web interface of an MPX transmitter. Serial port settings, such as baud rate, flow control, data size, stop bits and parity are also configurable only via the transmitter’s web interface. When serial passthrough is enabled, these settings are forwarded to all receiver units within the extender network. When serial mode is disabled, there is no processing of serial data on either the transmitter or the receiver(s).

Serial settings on all serially attached devices must correspond with the serial settings established via the web interface on the transmitter.

In summary, serial operation of the product is as follows:

•If simple passthrough is selected, then data received at the serial port of the transmitter will be broadcast through the extension network to all bound receivers and, in turn, to all serially attached display devices.

•If primary only passthrough is selected, then data received at the serial port of the transmitter will be sent only to the primary receiver. This mode allows bidirectional communication with a single device. Using the Primary radio button provided on the Bindings page, it is possi ble to switch serial control from one receiver to another . In addition to serial connectivity, IR control and EDID passing are tied to the primary receiver. Thus, it is important to consider the full impact of selecting a new primary receiver.

• If serial passthrough is disabled, then serial data received at the serial port on the transmitter will be ignored.

• If any passthrough mode is enabled and a primary receiver is selected, then data received from the device attached to the serial port of the primary receiver will be forwarded across the extension network to the MPX transmitter and, in turn, to the device attached to transmitter’s serial port.

• If a primary receiver is not selected and serial passthrough is enabled, then serial data will be broadcast from the transmitter to all bound receivers; however, bi-directional transfers will not be available.

• All serial settings must be made via the web interface on the transmitter. The web interfa ce on the receiver does not offer serial configuration options.

Chapter 4: Additional Functions 51

Figure 4.4 illustrates the basic flow of serial data among MPX units and attached devices.

Figure 4.4: Serial Passthrough Mode

Use the Serial Passthrough parameters section on the transmitter’s Serial Settings page to specify the serial mode and settings.

To configure serial passthrough modes:

1. Select Serial Settings from the Transmitter Menu, located on the left side of the web page. Figure 4.5 on page 52 illustrates these settings.

2. Choose one of the following Serial Passthrough Modes from the drop-down list: a. Disabled: Serial port on the transmitter and receiver units is not used. b. Simple passthru: Serial data received at the serial port of the transmitter will be broadcast

I/R Control

Each MPX extender includes an IR(rx) receiver and an IR(tx) port. The IR(rx) receiver is built into MPX1000 products. MPX1500 products feature a 2.5mm jack for connection of an optional (part number IR-RX) external IR receiver. All MPX products feature a 3.5mm jack for connection of an external dual IR(tx) emitter. IR control strings generated from a remote controller may be forwarded across the extension network or locally forwarded from the IR(rx) to the IR(tx) port on the same MPX unit.

IR extension permits a presenter to control a source device from the location of the display device. Local loopback of IR data permits an administrator to manage display devices from the equipment rack and/or a presenter to control a display device from the location of the display.

Similar to serial data, IR data is broadcast across the extension network from an MPX transmitter to all bound receivers. Bi-directional IR data is limited to the transmitter and the primary receiver.

For the sake of clarity, the flow of IR data from the IR(rx) receiver to the IR(tx) port on the same MPX unit shall be referred to as IR local loopback and the flow of IR data across the extension network shall be called IR extension.

IR functionality works as follows:

• Upon boot up, an MPX transmitter will forward IR data detected at its IR(rx) receiver to all bound receivers across the extension network. This flow cannot be disabled.

Chapter 4: Additional Functions 53

• When an MPX receiver is selected as the primary receiver, IR data detected at its IR(rx) receiver will be forwarded across the extension network to the MPX transmitter, where it will be emitted to the source device through the dual emitter. This IR data will not be forwarded to other MPX receivers. This flow cannot be disabled.

• The web interface of each unit offers an IR Local Loopback setting. This setting affects IR local loopback only. Altering this setting has no effect upon the flow of IR data across the extension network.

Figure 4.6 illustrates the flow of IR data from the MPX transmitter to a single MPX receiver. This data, however, will be received by all bound receivers. This functionality allows an administrator to send control strings such as on/off to display devices from the equipment rack.

Figure 4.6: IR Flow: Transmitter to Receiver

Figure 4.7 illustrates the flow of IR data from the primary MPX receiver to the MPX transmitter. This allows a presenter to send control strings, such as play/pause, to source devices from the location of the display device. A single IRB-100 dual emitter is supplied with the MPX transmitter. Should it be necessary to control more than two source devices, Avocent offers the IRB-Y splitter, which allows two IRB-100 dual emitters to be attached to a single MPX transmitter. Additional IRB-100 emitters may also be purchased separately. The MPX transmitter, or receiver, is capable of driving up to 4 emitters (two IRB-100s).

54 MPX Extender Installer/User Guide

Figure 4.7: IR Flow: Primary Receiver to Transmitter

Chapter 4: Additional Functions 55

Figure 4.8 illustrates local looping of IR commands. This allows source or display devices to be controlled locally.

Figure 4.8: IR Loopback

NOTE: IR data looped locally within an MPX transmitter or the primary receiver will also be sent normally across

the extension network. IR data looped locally on a receiver other than the primary receiver will not be forwarded to the extension network.

NOTE: The product provides contention handling to prevent the inadvertent mixing of IR extension data with IR loopback data. For this reason, the local IR loopback function at an MPX receiver is temporarily disabled while the unit is processing IR data received from the MPX transmitter. Similarly, if IR blaster mode is enabled on a receiver, any IR data sent from the transmitter to that receiver is ignored (and not emitted) by that receiver while the receiver is emitting IR data detected locally by its own IR receive port. Should contention occur, it will be necessary to repeat the ignored IR command via the remote.

Configuring IR control

Use the IR Blaster section on the Configuration web page to enable or disable local IR loopback, which is the flow of data from the IR(rx) receiver to the IR(tx) emitter port on the same MPX extender. IR extension, the flow of data across the extension network, is unaffected by this setting.

To configure IR control on a transmitter:

1. Select Serial Settings from the Transmitter Menu, located on the left side of the web page. Figure 4.9 on page 56 illustrates these settings.

2. Choose one of the following IR Local Loopback modes from the drop-down list: a. Disabled – IR local loopback is disabled b. Enabled – IR local loopback is enabled

3. Click Apply to save the changes.

56 MPX Extender Installer/User Guide

Figure 4.9: Serial Settings Page: IR Parameters

Regardless of the IR blaster mode setting, all IR data received by the local IR receiver port on the transmitter is forwarded to all connected receivers. This IR data will be sent to the IR transmit port at each of those receivers.

To configure IR control on a receiver:

1. Select Serial Settings from the Receiver Menu, located on the left side of the web page, Figure

4.9 on page 56 illustrates these settings.

3. Click Apply to save the changes.

Status Monitoring

The MPX transmitter provides two web pages for system monitoring: the Connection Status web page and the Media LAN Performance web page. The Connection Status page offers a status table for transmitter and a separate table for status of each receiver. The MPX receivers provide similar web pages.

Connection status

The Connection Status page on the transmitter displays the operational status of the transmitter and all bound receivers.

Figure E.1 on page 74 illustrates this web page. The content on this page dynamically refreshes every five seconds. Status table entries are largely common to both MPX transmitters and receivers; however, some functions are specific to transmitters or receivers.

Appendix B: Radio Considerations

The number, thickness and location of walls, ceilings and other objects that signals pass through affect the range of MPX extenders. A typical wall has metal or wood studs covered on each side by a single layer of gypsum or plaster board. Useful transmission range will vary depending on the types of materials, obstructions and background radio frequency noise at your place of installation.

To maximize your wireless range:

1. Keep the number of walls and ceilings between the transmitter and receiver to a minimum; each wall or ceiling can reduce your wireless product’s range.

2. Position a direct line between your transmitter and receiver so that the signal will travel straight through a wall or ceiling. A wall that is 1.5 feet thick (.5 meters) at a 45°angle appears to be almost 3 feet (1 meter) thick; at a 2°angle, it looks over 42 feet (14 meters) thick!

3. If possible, position your devices and extenders so that the signal passes through drywall or open doorways and not other materials. Building materials such as a solid metal door or aluminum studs can impede the wireless signal and will have a negative effect on the wireless

range.

4. Keep your MPX transmitter and receivers away (at least 3 to 6 feet or 1 to 2 meters) from electrical devices or appliances that generate RF noise.

5. Antenna extension cables result in signal loss. When possible , move the transmitter o r receiver into the desired position in lieu of using an extension cable. When cables are necessary, use the shortest Avocent-certified cable that allows you to properly posi tion your antenna. Daisychaining of antenna extension cables is not supported. Carefully follow installation instructions provided with your cable kit and properly configure the extender when using extension cables as described in

“Antenna Options” on page 67.

NOTE: Signals will not pass through concrete walls or titanium coated glass.

The MPX extender provides wireless transmission over the Unlicensed National Information Infrastructure (UNII) and on the Industrial, Scientific, and Medical (IS M ) radio bands.

The product is able to operate over following bands:

• UNII 1: (4 channels) 5.15-5.25 GHz

• UNII 3: (4 channels) 5.725 to 5.825 GHz

• ISM: (11 channels) 2.412 to 2.462 GHz (Available for use within the United States)

Firmware upgrades, including Dynamic Frequency Selection (DFS), will be provided, allowing the product to transmit in the following frequencies:

• UNII 2: (4 channels) 5.25-5.35 GHz

• ETSI: (11 channels) 5.470-5.725 GHz

Appendices 67

Antenna Options

Various antenna options are available for MPX extenders, including specialized antennas, antenna extension kits and lightening arrestors. The following sections describe these options and offer an overview of installation instructions.

NOTE: ISM band antennas and UNII band antennas are tuned for operation in their specific bands. An ISM antenna is not effective for UNII-band radio transmission and vice-versa. Take care to choose an appropriate antenna for the wireless channel that has been selected.

Installation of antenna options

Installation of antenna options have a direct impact on effective radiated power of MPX extenders.

NOTE: Because antenna options have a direct impact on the effective radiated power of MPX extenders, it is important to use only Avocent-certified options. Furthermore, antenna options should be used only as described herein. Misuse of these options could result in excessive radiated power or degraded performance.

To Install antenna options:

1. Physically install the antenna, arrestor or extender as described in the instructions provided with the option. It is acceptable to intermix antenna types within an extension network. For example, a transmitter equipped with omni-directional antennas may communicate with receivers using directional antennas. If you intermix antenna types on the same unit, then con

figure the unit for the highest gain antenna. For example, if you install a 3dB and 8dB gain antenna on the same extender, then configure the extender for use with your 8dB antenn a.

2. Launch a browser client to the transmitter.

3. Select the System Settings page. Figure 3.3 on page 29 illustrates the System Settings page.

4. Within the Antenna Type pull-down menu, select the antenna installed on your extender. The following specialized antennas are available for use with MPX extenders:

a. LGA51G-OMN: A low gain omni-directional antenna tuned for best performance in the

UNI 1 and 2 bands. This is the default antenna.

b. HGA51G-DIR30: A high gain, directional antenna tuned for best performance in the UNII

1 and 2 bands.

c. LGA55G-OMN: A low gain omni-directional antenna tuned for best performance in the

UNI 3 and ETSI bands.

d. LGA24G-OMN: A low gain omni-directional antenna tuned for best performance in the

ISM band.

e. IG A24G-OMN: An intermediate gain omni-directional antenna tuned for best

performance in the ISM band.

f. Several generic antennas are listed in the pull-down menu. These entries represent

antennas that are anticipated for future release by Avocent. Use of third-party antennas is neither implied or supported by means of these entries. If you purchase an optional

68 MPX Extender Installer/User Guide

antenna from Avocent that is not specifically listed in the pull-down list, then select the generic antenna that most closely resembles the antenna that you have installed.

High gain and directional ant ennas act to concentrate radio waves in a narrow beam or plane in the same way that a megaphone concentrates sound waves. These antennas are appropriate when you need to maximize transmission distance. Low gain omni antennas allow radio waves to propagate in a more spherical manner. Because the radio’s energy is sent equally in all directions, the effective transmission range drops off more quickly than if it were concentrated into a narrow beam. Use of these antennas allow transmitters to be placed in closer proximity. Low gain antennas allow you to take advantage of reflections that might bounce off of floors, walls and ceilings. Use of lower frequency antennas are preferable for penetration of walls or other obstructions. In multi-transmitter environments, use of high frequency antennas allo ws for good RF separation from extenders using low frequency antennas within the sam e RF envelope.

5. Within the Lightening Arrestor pull-down menu, indicate if an arrestor is present or not.

6. Within the Antenna Extension pull-down menu, indicate which extension is installed, if any. Supported antenna extenders include:

a. 1 Meter: Provides a 1 meter anten na extensio n. b. 2 Meter: Provides a 2 meter antenna extension. c. 3 Meter: Provides a 3 meter anten na extensio n.

NOTE: Although antenna extension cables allow for optimized antenna placement, they result in signal loss. When properly installed and configured, the firmware will attempt to boost the transmit power to compensate for this loss. Daisy-chaining of extension cables to increase the cable length is not supported as this will result in excessive degradation of signal strength.

7. If you have installed a custom antenna, then you will need to configure the extender for a channel in the appropriate band. Select Media LAN Settings from the main menu. From Wireless Channel pull-down menu, select an appropriate channel.

8. Repeat steps 3 through 7 for each active receiver.

Proper configuration allows your extenders to properly adjust radio transmit power as needed to compensate for extension cable loss. Proper configuration also allows your extenders to accurately report effective radiated power as effected by antenna gain.

Appendix C: MPX Status LEDs

MPX1000 receivers and all MPX1500 products feature five front-panel LEDs that are used to convey state and status information. The following diagram illustrates the order and color of the LEDs:

Figure C.1: MPX LED Status Indicators

LED sequences convey operational states and status of the receiver. The following sections define the key LED sequences of the product.

NOTE: When a LED is described as Flashing, it is flashing on and off at a rate of 4 flashes per second. When a LED is described as Blinking, it is blinking on and off at a slower rate of 1.5 seconds per blink. When a LED is described as On Solid, it is continuously illuminated and is neither blinking nor flashing.

Power-on initialization status

During system initialization, the LEDs will turn on from left to right until all LEDs are on. Then, the LEDs will turn off from right to left until all LEDs are off. This pattern will repeat throughout the system initialization process.

If a Power On Self Test (POST) error occurs, a specific pattern will be displayed. Please make note of the pattern prior to contacting Avocent technical support.

Appendix D: Audio

The HDMI media module for MPX1000 extenders offers support for embedded digital audio and unbalanced analog audio via left and right RCA jacks. The HD15 media module supports only unbalanced analog audio. Analog audio is sampled at 48Khz, which is CD quality audio.

NOTE: With MPX1000 units you have received two snap-on ferrites. If you are using the analog audio (RCA Jacks) these ferrites should be applied to each end of the cables. Apply the ferrites approximately one inch from the cable ends. One ferrite goes around both cables.

MPX1500 extenders offer embedded HDMI digital audio as well as unbalanced analog audio via left and right RCA jacks. Snap on ferrites are not required for the use with MPX1500 extenders. Depending upon your firmware version, the MPX1500 receiver may or may not support coaxial and optical digital audio (S/PDIF).

Because transmitters and receivers can be configured for differing media types, a variety of configurations are possible. The following sections provide detailed information regarding these additional configurations.

Digital Source Device Considerations

When an HDMI source is received, the MPX transmitter ignores the external analog audio jacks and passes the embedded digital audio signal. When a DVI-D signal is received, the transmitter will accept audio input from the RCA jacks. In both cases, audio will be output by the receiver in the form of embedded digital audio and external analog audio.

NOTE: If the primary receiver is attached to a VGA or DVI-D display, the EDID information provided by the display will disable digital audio at the source device. In this case, the transmitter will pass analog audio even if the source device connection is HDMI. Thus, if digital audio is required, be sure to select a receiver attached to an HDMI display device.

NOTE: If the digital audio embedded within the HDMI signal is 96KHz, then analog output on the receiver modules will be disabled. Digital audio will continue normally.

Analog Source Device Considerations

A transmitter that is accepting analog video will always input audio on the dual RCA jacks. When passed to a receiver with an attached HDMI display device, the audio will be embedded within the HDMI signal and also available on the dual RCA jacks.

When analog video devices are attached to both the transmitter and receiver, audio will be present only on the dual RCA jacks.

Appendix E: Video Troubleshooting

The following troubleshooting tips should help you to resolve most common setup and initialization issues. If your problem persists, please contact Avocent technical support for additional help.

Available Information

The Transmitter Status table, illustrated in Figure E.1, on the Connection Status page of an MPX transmitter offers additional information. If video is actively being processed by the transmitter, the A/V Source Resolution field indicates the current resolution.

Figure E.1: Transmitter Status Table

The Transmitter Status table provides three additional fields, as follows:

Appendices 75

a. Primary Video Resolutions: This field contains a list of all resolutions that the Primary

Receiver has reported to the transmitter. These values would have come from the display device itself or from the Display Settings page of the receiver.

b. Video Resolutions in Use: This field indicates the list of resolutions that have been

reported to the source device.

c. RGB Video Resoluti ons Sto red: This field indicates the resolutions that are currently

stored in the Active EDID string of the transmitter.

The Transmitter Performance and Receiver Performance tables on the Media LAN Performance web page of an MPX transmitter, illustrated in

Figure E.2, provide real-time status of media LAN bandwidth utilization. The Current Video Data Rate is the target transmit data rate. This value should fall between the maximum data rate and the minimum data rate settings. The Transmitted Total Bitrate is the amount of audio and video data that the transmitter has actually transmitted per second since the last page update. Bitrate status for retransmitted data is also provided. The receiver table indicates the amount of real-time data received from the media LAN as well as the amount of retransmitted, recovered and lost data. Chronic status of missing data is a symptom of an adverse condition that should diagnosed and resolved.

Common Tuning Needs

Video is restricted to 640x480: This is an indication that the MPX transmitter has not received valid EDID information from the display device. The following list provides potential causes and suggests actions to remedy the situation:

76 MPX Extender Installer/User Guide

• Improper initial power sequence: It is possible that the source device obtained EDID

information from the MPX transmitter before device information was obtained from the display device. To resolve this, follow the suggested power up sequence provided in

“Ini-

tiating A Media Session” on page 38.

• The display device is not a plug-and-play ready: It is possible that the display device

does not offer EDID information. The Display Device Settings page will indicate if the display device is not plug-and-play ready. If this is the case, use the provided table to enable appropriate resolutions for the display device. Be careful not to enable resolutions that the display cannot support.

• The display device submitted an improperly formed EDID string: Should this happen,

the transmitter will discard the entire string. Thus, the default EDID will remain in effect. In this case, use the Display Device Settings table on the MPX receiver to enable appropri

ate resolutions for the display device.

• The VGA cable is damaged or does not pass data on the DDC channel: Pins 12 and

15: of a VGA cable represent DDC data and clock, respectively. EDID information is passed via the DDC channel. Verify proper operation of your VGA cable.

No video is visible: This is an indication that the display device is either not properly connected or is not compatible with MPX extenders. The following troubleshooting steps may help to resolve this issue.

• For all display devices:

• Launch your browser to the Connection Status page on the transmitter. Helpful error information may be displayed in the Transmitter Status table.

• Connect a display device directly to your source devi ce. If active media is not displayed, then resolve the issue before attempting to extend the signal. If active media is present, then verify proper operation of the transmitter and receiver video cables and adapters, if

any.

• Power off all receivers other than the primary. W orking with a reduced network will allow you to simplify the troubleshooting environment.

• View the resolution and frame rate tables in the appendix of this manual to determine if your source device is operating within supported parameters.

• If you have selected wireless operation, select a different channel in the Wireless Media LAN settings to ensure that there is not a conflict with other nearby wireless devices.

• It might be useful to attempt using a wired media LAN to check for possible radiorelated

issues.

• Make sure that you have selected a primary receiver. The primary is responsible for generation of EDID information for the source device.

• For HDMI or DVI-D display devices:

Appendices 77

• Initiate a video hot plug of the source and display devices to ensure that the EDID information has been read and transferred across the extension network.

• Power cycle the transmitter to clear invalid HDCP keys, which may have been collected from a non-valid display device. An invalid key will prevent the transmitter from sending protected

content.

• Determine if you are sending protected content. If so, do all of the display devices have appropriate content protection keys?

• If only one display is not working, try making it the primary. Perform a hotplug of the video connection (HDMI, VGA). If the problem is resolved and the displays are dif ferent models, there may be a incompatibility between the options these monitors support.

Motion video is choppy: This is an indication that frames are being dropped. “Fine tuning suggestions” on page 47 provides steps to resolve this issue.

Additional tips for VGA display devices

Display devices differ widely in their support of video resolution, refresh rates, color depth and other configurable features. To allow source and display devices to negotiate available settings in a plug-and-play manner, a display data channel standard has been adopted by the industry. The standard supported by MPX extenders is DDC2B. This standard is adhered to by most VGA, DVI, and HDMI display devices. Compliant display devices contain a PROM that can be read by a source device across a display data channel (DDC). The PROM contains formatted information about the capabilities of the display. This information is commonly referred to as extended display information data, or EDID string for short.

DVI-D and HDMI source devices will dynamically query this information when a display device hot-plug event is detected. Thus, displays are immediately available. Most VGA computer source devices such as graphics cards, however, query information only once, upon power up. For this reason it is particularly important that EDID information is passed through the extension ne twork and assembled by the transmitter into the Active EDID string before power up of VGA source device. Therefore, the power sequence of MPX extenders, display devices, and source device is

critical when using a VGA source device.

NOTE: EDID information is maintained by the MPX transmitter in non-volatile storage; thus, the order of power up sequencing is important only during initial installation.

If you followed the recommended power up procedure and no video is visible at the display device, then the following tips may help you to resolve your problem.

• The VGA source may be operating at a resolution not supported by the MPX transmitter.

• If you are on a laptop, toggle the video back to the laptop display and check the resolution of the secondary monitor. To test the connection between the transmitter and the receiver, change the secondary monitor setting to 640 x 480 @ 60Hz resolution. Again, toggle the video to the VGA connector. Video should appear within 30 seconds.

78 MPX Extender Installer/User Guide

• If your source device is a desktop PC or server, then you must disconnect the MPX transmitter from its VGA port and connect a VGA monitor in its place. It may be necessary to reboot the computer to establish video. Change the resolution to 640 x 480 @ 60Hz. After changing the resolution on the PC, restart the PC (or power cycle your VGA source). Quickly reconnect to the MPX transmitter while the VGA source is

initializing.

After you have obtained video at the 640 x 480 resolution, you may change the reso lution on the VGA source to one of the other supported resolutions.
