Product Overview

The NMX-ENC-N2151 4K Encoder and NMX-DEC-N2251 4K Decoder provide users with the industry's most versatile solution for distributing AV over a converged network at resolutions up to 4096×2160. JPEG2000 compression allows Ultra HD media to be switched and distributed over standard Gigabit Ethernet networks. Ultra HD signals from the NMX-ENC-N2151 Encoder are provided simultaneously as: 1) a JPEG2000-compressed 200-600 Mbps stream through the RJ45 connector or small-form-pluggable (SFP+) port (10Gb), and 2) an uncompressed stream through the SFP+ connector (via a fiber module). Any source can be sent to any number of displays by routing through managed switches. System scalability is limited only by uplink and stacking connector bandwidths.

Standard features like output scaling (Decoder), bi-directional serial, IR output, embedded 7.1 audio, and KVM-over-IP extension are included. The NMX-ENC-N2151-C and NMX-DEC-N2251-C form-factors are compatible with the NMX-ACC-N9206 card cage for high-density applications.

The NMX-ENC-N2151 and NMX-DEC-N2251 together create the perfect solution for video matrix applications where resolutions up to 4K are required. Common applications include classrooms, conference rooms, performing arts centers, and sports bars.

Features include:

• Output Scaling — Video scaling at the output (Decoder) allows seamless switching from any source, at any resolution, to any display or projector, while preserving video fidelity.
• Infrared (IR) — Infrared emitter connection allows control of low-cost, IR-only display devices.
• Onboard Control — All N-Series Encoders and Decoders have on-board, built-in control capability via events that can trigger any number of TCP/UDP commands to other IP controllable devices.
  • Pass-through HDMI interface (Encoder) — allows easy installation with local display such as desktop PC applications.
• Unlimited Scalability — Grow the video matrix by adding Encoders or Decoders as needed (within the bandwidth limits of the uplink and stacking connectors).
• Stand Alone or Card — Available as a stand alone device, or card for use with NMX-ACC-N9206.

The N2X51 units are available in stand-alone and card versions. The stand-alone version can be free standing, surface mounted, wall mounted, or rack mounted. All cards must be rack mounted using the NMX-ACC-N9206 Card Cage (sold separately).

Surface and Wall Mounting

To mount your N2X51 stand-alone unit to a flat surface or wall, follow these steps:

1. Remove the four screws from the bottom of the unit and use them to attach the mounting wings (sold separately - part number NMX-ACC-N9101). See Figure 5.
2. Place the unit against the solid surface to which you want it mounted.
3. Using standard hardware, attach the unit through each of the slots of the newly-attached mounting wings.
4. Connect the appropriate cables necessary for your application. Refer to the sections: Connecting Decoders to the Network on page 14 and: Connecting Encoders to the Network and Configuring Stream Settings on page 15 for more information on these connections.

FIG. 5 Installing Mounting Wings

Rack Mounting

N2X51 Series Stand-Alone Units

The N-Series 1RU Rack Shelf (part number NMX-ACC-N9102) accommodates up to two stand-alone N-Series Encoders or Decoders, side by side (any combination of product series).

FIG. 6 Rack Mounting Stand-Alone Units

N2X51 Series Cards

The N-Series Card Cage (part number NMX-ACC-N9206) accommodates any combination of up to six N-Series Encoder/Decoder cards. The NMX-ACC-N9206 card chassis provides 12V connections to all cards (installed as the primary power source).

Use either of the following formulas to calculate how much power is required for the N9206. Formulas are based on the power requirements of each installed card (e.g., Power_Slot1 = the power requirements for whatever card is installed in the first slot). These formulas adds a 20% margin to the power requirements of the cards to allow for the chassis cooling fan power consumption as well as any inherent power supply losses.

Total Power = ( Power_Slot1 + Power_Slot2 + Power_Slot3 + Power_Slot4 + Power_Slot5 + Power_Slot6 ) * 1. 2

or

Total BTU / hr = ( BTU / hr_Slot1 + BTU / hr_Slot2 + BTU / hr_Slot3 + BTU / hr_Slot4 + BTU / hr_Slot5 + BTU / hr_Slot6 ) * 1. 2

To install N2X51 Series cards into the N9206 Card Cage, follow these steps:

1. Gently slide the card into cage slot. Make sure the card is properly aligned with guides. The card's front LED indicators should align with holes in the cage's faceplate. See Figure 7.

FIG. 7 Installing Cards

1. Align the thumb screw on back plate before seating card into cage.
2. Firmly seat the card and tighten the thumb screw by hand to secure card placement.
3. Use one of the six Phoenix connector cables (included in shipment with the Card Cage) to connect the card's 12VDC input Phoenix connector to one of the cage's six 12VDC outputs.
4. Repeat these steps until all cards are properly installed. See Figure 8.

FIG. 8 Fully-Populated Card Cage

1. For proper airflow, cover any unused card slots with faceplate blanks. Blanks are sold separately (part number N9210).
2. Make sure the Card Cage's power cord is plugged in for proper cooling. The POWER LED on the front of the cage should always be on.

CAUTION: Keep the Card Cage's power cord plugged in at all times so that the internal fans are always running. Failure to do so could void the warranty of the cage and all installed cards. The card cage cooling fans cannot be powered by PoEn the event of a loss of main power to the card cage. Please remedy power losses immediately to avoid potential overheating hazards.

NOTE: Mounting accessories are sold separately and are compatible with most N-Series devices. Contact a sales representative or visit our website for details.

Step-by-Step Installation Instructions

This section provides step-by-step guidance for installing and configuring equipment from the N-Series product family on your network. The steps provided here assume the following to be true:

1. There are switches operational on the network.

N-Series equipment can operate on many different brands of networking equipment. The network itself needs to meet certain requirements to be able to support deployment. These instructions assume that you have purchased and installed a pre-configured switch from AMX or that your existing equipment meets the following physical and protocol requirements:

• Layer 2 (with IGMP Multicast Protocol), OR Layer 3 (also known as "multi-layer")
  • Gigabit Ethernet
  • I G M P S n o o p i n g
• IGMP Snooping Querier (which only needs to be enabled on a single switch within the network)

NOTE: To proceed with this installation, the switches must already be successfully connected to your network. If needed, refer to your product's documentation for installation instructions.

2. Deployment considerations have been made for the addition of high-speed video.

Our Networked AV solutions provide unsurpassed video and audio quality at bandwidths appropriate to any network segment or link. Matrix switches as large as 1200x800 have been constructed on a house network using N-Series equipment. Alternatively, many customers choose to deploy on physically separate networks in order to use low-cost network appliances but keep video traffic separate from data and voice.

3. N-Able software has been loaded on the computer you are using to configure the equipment.

From your host computer, download N-Able (our free setup utility software):

PC version - http://www.amx.com/products/N-ABLE-PC.asp

Mac version - http://www.amx.com/products/N-ABLE-MAC.asp

This software is designed to set up and control the equipment during initial deployment, however, it is not always the best solution for production-type or primary user control. Refer to Control Options on page 21 for details on the available control options.

NOTE: For a more detailed requirements list, refer to Appendix A: Minimum Network Requirements on page 65.

Step 1: Setting Up Your Host Computer

In order to communicate with N-Series products, your devices must be on the same subnet as the host computer. N2X51 units are shipped in DHCP mode and the IP address will be assigned automatically based on the network DHCP server. If no DHCP server is found, the unit will use Auto IP mode with a default IP address of 169.254.xxx.xxx.

Before beginning installation, you may need to make some changes to the computer running N-Able. These steps show how this can be accomplished in a Microsoft Windows environment.

1. From the Start menu, select Control Panel > Network and Sharing Center.

NOTE: If the computer does not need Internet access, you can simply enter a unique 169.254.xxx.xxx IP address with a 255.255.0.0 subnet mask. Contact your network administrator if you are unsure of how to configure the existing network. N-Series units will not self-assign in the 169.254.0.xxx range.

NOTE: If the computer has a statically-assigned IP address, click the Advanced button. Then click Add to enter a unique 169.254.xxx.xxx address with a Subnet Mask of 255.255.0.0 and a Default Gateway of 169.254.1.1.

Step 2: Connecting Decoders to the Network

The digital connection from a Decoder HDMI OUT port (female) to a display is accomplished using either an HDMI cable or DVI-D (through adapter). N2251 units support embedded audio input and output on the HDMI ports; however, some display devices (e.g., many monitors) do not support embedded audio. When using such a display, use the AUDIO port for separate transmission of sound and turn HDMI Audio off (on the Settings page) to avoid video display issues.

Power is supplied via an external power supply. Refer to the following steps and Figure 9 for guidance.

1. Using a Cat-5e or higher cable, connect your N2251 Decoder's P0 port to a switch (or connect SFP+ to the P1 port).
2. Connect the 12V regulated power supply (included in shipment) to the two-pin terminal block plug connector (labeled +12V 2A).
3. Connect the display you would like to use for that Decoder (monitor, projector, etc.) to the Decoder's HDMI OUT port using an HDMI cable (or DVI through adapter). This must be a digital video connection.

FIG. 9 Decoder Connections

1. Repeat Steps 1 and 2 until all Decoders are installed on the network.

2. Once the Decoders and displays are connected and powered up, the LocalPlay screen appears on the displays.

NOTE: If the LocalPlay screen does not appear, refer to Chapter 5, Troubleshooting for more guidance.

Step 3: Connecting Encoders to the Network and Configuring Stream Settings

1. Using a Cat-5e or higher cable, connect your N2151 Encoder's P0 port to a switch (or connect SFP+ to the P1 port).

2. Connect the 12V regulated power supply (included in shipment) to the two-pin terminal block plug connector (labeled +12V 2A).

3. In N-Able, select the Unit Management tab and click the Auto Discover button (if the table has not already populated itself with the installed units). See Figure 10.

FIG. 10 Unit Management Page

1. Find your Encoder in the list. N2X51 units are displayed on the following tabs:

2. Unit Management tab — N2X51 units have N-Series 4K Encoder/Decoder listed in their Type fields.

3. Video Matrix tab — N2X51 units are found on the Uncompressed 4K and Compressed 4K sub-tabs (as shown in Figure 11).

NOTE: If using multiple Encoders in your set up, it is important to plug in and configure one Encoder at a time. All Encoders come pre-configured to use stream 1. As you add Encoders to the network, you will need to set them up to use different streams.

Encoders are listed across the top of the page.

Decoders are listed down the left side of the page.

1. Double-click the Encoder's name in the list. The N-Series Encoder Login page is displayed (see Figure 12). If prompted, use the following default login credentials to log in for the first time. These can be changed later on the Settings page. Default username: admin Default password: password

FIG. 12 Login Page

NOTE: The Login page is only displayed if N-Able's stored username/password does not match the unit's username/password. A default system will match. The default password for N-Able can be modified under N-Able>Settings.

1. The Settings page is displayed (see Figure 13).
2. Change the Stream setting. We recommend setting Stream to a number between 2 and 254 (it is required that the number be less than 32,512). Use the P0 and P1 check boxes to designate which port to send the stream over.

NOTE: Uncompressed streams (880-4250 Mbps) are only supported on the P1 port. Compressed streams (200-600 Mbps) are supported on either P0 or P1.

FIG. 13 Changing Stream Setting

1. Repeat these steps until all Encoders are connected to the network and configured with an appropriate Stream number.

NOTE: Each Encoder's Stream number must be unique to all other Encoders on the network.

NOTE: Screen-by-screen descriptions of the web interface options are provided for your reference in the Encoder Configuration Options section on page 24 and the Decoder Configuration Options section on page 42.

Step 4: Configuring Decoder and Encoder IP addresses (if needed)

By default, all Decoders and Encoders are preset to DHCP mode. When first connected to the network, an IP address is assigned automatically based on the network DHCP server. If no DHCP server is found, the unit will use Auto IP mode (with an IP address pre-configured to 169.254.xxx.xxx with a subnet mask of 255.255.0.0).

How IP Address Changes Affect Unit Control

As discussed previously, N-Able control is dependent upon the host computer being in the same IP address range as the N-Series devices. Therefore, before making any N2X51 IP address changes, we recommend having two statically-assigned IP addresses on your computer.

• Configure the first IP address to be in the range of the default N-Series IP settings (i.e., in the 169.254.xxx.xxx range), AND
• Configure a second IP address in the range of the IP address you are planning to assign to the units (or when using DHCP, an address within the defined range for your network).

Changing IP Addresses

There are two ways to assign new IP addresses to your N2X51 units using N-Able:

• Option 1: Log in to each unit individually and make the changes on the Settings page.
• Option 2: Export a comma-separated value (CSV) file, make changes to all units in the resulting file, and import the CSV file into N-Able to apply the changes.

Option 1: Assigning IP Addresses Individually (using the Settings page)

1. Find the unit you wish to change in the control matrix (either on the Unit Management tab or the Video Matrix > Uncompressed/Compressed 4K tab).
2. Double-click the unit and log in.
3. Go to the Settings page and make IP address changes for that unit either by setting a STATIC address or by enabling DHCP (see Figure 14).

FIG. 14 Network Setup Section of the Settings Page

1. Click the Trial Save button.
2. Return to the Settings page through the newly-configured IP address.
3. Once the Settings page appears (successfully using the new IP address) click the Confirm button to lock in your changes.

NOTE: If you lose communication for any reason, remove power from the N2X51, wait one minute, and plug it back in. This restores the unit to the original IP address.

Option 2: Assigning IP Addresses to Multiple Units (using CSV files)

N-Able provides the ability to export and import CSV files. Once units are auto-discovered in N-Able, the CSV file can be exported into Excel where parameters such as IP address, subnet mask, gateway, stream number, audio settings, etc. can be configured. Once configured, import the CSV file back into N-Able to assign those parameters to the appropriate devices. Reboot the devices to activate the new settings. This procedure can be used to configure multiple networked AV devices at the same time. It can also provide valuable diagnostics by allowing you to see the last known device configuration as well as scan the network for new devices (regardless of IP configuration).

To configure units using a CSV file, follow these steps:

1. Make sure that you have performed an Auto Discover (on the Unit Management tab of N-Able) since connecting all of the new units to the network.
2. From N-Able's main menu bar, select N-Able > Export CSV.
3. Click Yes on the pop-up box informing you that a CSV file is about to be generated.

NOTE: A CSV file editor (e.g., Microsoft Excel) is necessary to proceed.

1. The folder containing your CSV file displays. Double-click the file to open it.
2. You can use this file to edit the IP mode, IP address, subnet mask, gateway IP address, stream number, etc. Once all changes have been made, save the file.

NOTE: Mac and Serial numbers must match and be present on the saved/modified version.

1. Go back into N-Able and select N-Able > Import CSV.
2. Browse to your saved CSV file and click Import.

Step 5: Connecting Encoders to an Input Source

Having already connected the Encoder(s) to the network and made the appropriate settings changes (as described in Step 3 and Step 4), you can now connect to the appropriate AV source(s). This connection from an Encoder HDMI IN port (female) to an input source is accomplished using either an HDMI cable or DVI-I (through adapter).

1. Connect the source you would like to use for the Encoder (camera, laptop, etc.) to the Encoder's HDMI IN port using an HDMI cable. If the source has an analog video output (such as VGA) use a VGA cable or appropriate adapters and connect it to the VGA IN port.
2. Repeat until all Encoders are connected to their sources.

FIG. 15 Encoder Connection to Source

Switching and Scaling Options

N-Series Encoders and Decoders make up a true AV matrix solution. In other words, one input can go to any or all outputs. Both Encoders and Decoders have internal scaling capabilities. Keep the following in mind:

• The input of an Encoder is the video and/or audio signal going into the Encoder.
• The output of an Encoder is the network stream.
• The input of a Decoder is the network stream.
• The output of a Decoder is the digital video and/or audio being transmitted out to the display device.

NOTE: Cropping and scaling features are not available when input is 3840x2160@50, 3840x2160@59.97, 3840x2160@60, 4096x2160@50, 4096x2160@59.97, or 4096x2160@60.

Seamless Switching

The N2X51 Series supports seamless switching capability if the scalers in the Decoders are all set to the same resolution and refresh rate. If the scalers are off, all of the sources must have the same resolution and refresh rate.

To get streams onto a Decoder, use the Video Matrix tab to route video from an Encoder to a Decoder. This works seamlessly if the previously mentioned settings are true. All you have to do is click the intersecting cell on the matrix, and click the Take button. See Figure 16 for an example.

Selecting this cell directs the Conference Rm Decoder to listen to the Conference Rm Encoder.

FIG. 16 Seamless Switching Using the Video Matrix

Control Options

For the most part, once the initial setup is complete, you will be primarily managing/configuring the Decoders. To better understand, think of Encoders as radio stations and Decoders as car radios. The Encoders are supplying the streams and, using the Decoders, you can "tune in" to the stream you want. Our N-Control solutions (N-Command, N-Act, and N-Touch) provide you with the most flexible management options available, ensuring you are getting the most from your digital media system.

Primary Control Options

During initial configuration and setup, the free N-Able setup utility is sufficient. However, N-Able is not recommended for production-level, primary-user control.

N-Command Controllers

These web-based hardware Controllers offer intuitive, powerful management of equipment, content, NVR recording/playback, and AV switching (using a web-based, point-and-click graphical matrix). The N-Command product line also offers:

• Simplified ASCII interface for third-party control via TCP/IP.
• N8002 and N8012 controllers have master/client failover protection.
• N8012 controller has hot-swappable drives and redundant power supplies.
  • Graphical presentation of video network connections.

- Full configuration control: assign fixed IP addresses for each N-Series component, adjust variable bit-rate for each video stream, etc.

- Additional software bundles (free with N-Command) allow you to easily create attractive touch panels for N-Series and third-party equipment control, as well as build software design walls of any size. Visit our website for more details on the available N-Command Controllers.

Third-Party Controllers

For direct control of N2X51 units from any Third Party Control system, please use the Direct Control API (available on our website).

N-Act | On-Board, Built-In Control

All N-Series Encoders and Decoders have on-board, built-in control capability via events that can trigger any number of TCP/UDP commands to other IP controllable devices. Included free with all N-Series Encoders/Decoders. See the section N-Act Page on page 36 for more information.

N-Touch | IP Wall Controller

This 240 x 320 capacitive touch display has Wi-Fi and Bluetooth for expanding control to mobile devices. Programming is done individually through the built-in web server or collectively to multiple units using an N-Command N8000 Series Controller. Multi-page custom graphics can be created using the free Panel Builder software (stored internally).

KVM Configuration

The N2151 Encoders and N2251 Decoders are KVM-capable. By default, USB connections are enabled and configured to follow video switching.

Basic Setup

Follow these steps for basic KVM configuration:

1. On the N2151 Encoder, connect the USB Mini-B port to the computer to be controlled.
2. Connect the computer's video output to the Encoder's HDMI IN port.
3. On the N2251 Decoder, connect the HDMI OUT to the display.
4. Connect a USB keyboard and mouse to the Decoder's USB Standard-A ports (they can be plugged into either port).

NOTE: For wireless devices, simply plug the wireless signal receivers into these ports.

1. Using N-Able, click the Unit Management tab.
2. Click the Auto Discover button to discover your new devices (if you have not already done so).
3. Once discovery is complete (and you see the new units listed in N-Able), click the Video Matrix tab.
4. On the matrix, click the intersecting cell for the desired Encoder/Decoder streaming combination.
5. Click the Take button to make the change to your matrix. The cell button turns green to indicate the connection was successful.

WARNING: You must assign KVM passwords to your Encoders and Decoders (as well as change the default login password from admin/password) in order for your system to be secure.

Video/USB Switching Options

USB Follows Video: By default, units can be switched using N-Able without modifying the configuration. When you switch video streams (using the matrix) the USB functionality will follow the video.

Independent USB Switching: Use N-Able's USB Matrix tab to switch USB control (without affecting video).

Independent Video Switching: To switch video streams without affecting USB control, first select N-Able > Settings from N-Able's main menu. When the N-Able Settings dialog box is displayed, disable the USB follows Video switching for KVM units. Now you can use the Video Matrix to switch video streams only.

Advanced KVM Setup (With Added Security Features)

You can configure devices for more advanced KVM operation on the Encoder and Decoder using N-Able's KVM Wizard. To access the wizard, select Tools > KVM Wizard from the N-Able main menu (as shown below in Figure 17).

FIG. 17 KVM Wizard

The following table describes some of the more advanced functionality.

Passwords and Permission Levels
Option Description
Permission Levels	Determines which Decoders can communicate with which Encoders. A Decoder must have a permission level that is equal to or greater than the Encoder in order for communication to be successful.
KVM Encoders table	Use the KVM Encoders table (on the Decoder's KVM page) to:Let the Decoder know the Encoder passwords it needs to establish communication.Add/remove Encoders from the Decoder's list.
Passwords	By default, KVM streams are encrypted with a common password. You can change the password on the Settings page of the Encoder. If you change Encoder passwords, you will need to supply the new information to the Decoders to allow communication to continue.A Decoder only receives password information for the Encoders on the network that have been associated with that Decoder.
Import and export KVM CSV files	Multiple Encoders and Decoders can be configured from a single CSV file (which is generated using the KVM Wizard in N-Able). Once all changes are made, upload the file to each unit using its KVM page.Click the Choose File button, browse to the CSV file you exported from the wizard, and click the Upload button.

NOTE: These options can also be managed in the unit's GUI (by clicking KVM from the main menu as shown in Figure 18). It is important to note that many of these options only appear on the KVM page when USB is enabled as well as KVM Advanced Settings. See KVM Page on page 58 for more details.

The Encoder Setup section of the Settings page is shown in Figure 21. Options are described in Table 1.

FIG. 21 Encoder Setup Section

TABLE 1 Settings Page: Encoder Setup Section

Option Description Notes
Device Name	Enter a user-friendly name for the unit.	More descriptive names in this field help you organize and manage the N-Series system efficiently. Names based on the unit's location and function are very useful. Some good examples areLobby-Left-VGA(for left side of lobby, VGA input) orCR201-HDMI(for Conference Room 201, HDMI input). Keep in mind the matrices are organized alphanumerically. Avoid using special characters.
TX Enable Enable to generate and transmit multicast streams.
Compressed Stream View/edit the current transmit compressed stream number. Enable the port you wish to transmit the stream on (P0or P1).		To better understand this setting, think of Encoders more like a channel on a cable box, rather than a traditional AV Matrix. Each Encoder must have a unique stream number, just like every channel must have a unique channel number (e.g., Food Network and HGTV cannot both be on channel 201).
Uncompressed Stream View/edit the current transmit uncompressed stream number. Enable the P1 checkbox if you want the unit to output an uncompressed stream.		P1 can stream both compressed and uncompressed, and it can do so simultaneously. If you prefer to use compressed video and disable uncompressed (so as not to overwhelm the network) disable this P1 checkbox.
Option	Description	Notes
Video Source	Select which input port is encoding video.	SelectingHDMI/VGAdeclares HDMI as the primary port and VGA as the secondary port (when there is no HDMI input). SelectingVGA/HDMIdeclares VGA as the primary port and HDMI as the secondary port.Selecting VGA onlyor HDMI onlydisables the other video input port.
Audio Input Type	Select Unbalanced(single-ended) orBalancedanalog audio input.
Live/Local Select live	video or locally stored images for transmission onto the network. When video is not available, it automatically goes into local mode.	When video is not available, the most recently played local playlist is displayed.

Image Quality Adjust	the compression level of the image. The further to the left on the slider, the more compression which will display as pixelization of the image.
Mute Enable to	stop the transmission of audio data onto the network.
Audio Source Set the	audio source to be disabled, enabled or selected automatically (see note).	TheAUTOsetting always corresponds to HDMI audio as long as there is an HDMI source. If the source is unplugged, it will automatically fall back to analog audio (if there is an analog source plugged in).
Color Space Correction Set	the color space settings for the Encoder (YcbCr, RGB) to be disabled, enabled, or selected automatically based on the source.	If you see a pink/green washed out screen (across the entire image), this can be changed by modifying color space settings. Most sources function withAutoselected but (for problematic sources) hard-set the value to what the source requires. It is best to do hard-set for all permanently installed sources (e.g., cameras, cable boxes, etc), but leaveAutoon for periodic sources (e.g., laptop inputs).
Advanced Settings	Refer toAdvanced Settingson page 28 for details on the options available from this link.
RS232 Settings	Refer toRS232 Settingson page 30 for details on the options available from this link.
Allow SVSI Multicast Disable this option to prevent the port from outputting multicast video traffic.		Particularly useful if you are connecting a non-SVSI device to a port for network-based control.

No audio is detected. • If there is no audio on all ____ Decoders, verify audio settings are correct on Encoder.If there is no audio on a single Decoder, verify audio settings are correct on Decoder.
Device has been discovered in N-Able, but the configuration pages do not open when double-clicking device name on the Video Matrix page.	Make sure your computer is in the same IP address range as the unit. See :Setting Up Your Host Computeron page 12 for more information.
When changing the audio type, there are problems with audio in/out.	Check theAudio Source(Encoder) andHDMI Audio(Decoder) settings on theSettingspage. For example, if you are trying to change the audio type to make the input of the Encoder HDMI embedded audio in/analog audio out from the Decoder, these settings cannot be set toAuto.Set the Encoder toAudio Source >ON(embedded digital audio on an HDMI connection) and the Decoder toEnable HDMI Audio >OFF(analog output on the Phoenix connection).
Not receiving audio.	Check that the Decoder has proper audio stream setting (typically by enabling Audio follows Video).
Not receiving analog video through the Encoder.	If using a Y cable (N9420) and an HDMI source is already connected to the Encoder, disconnect the HDMI source. Encoders give preference to HDMI and will not allow analog signal to pass while it is connected.
Video output is stuttering.	This could be a network bandwidth issue where the full video stream is not reliably getting from Encoder to Decoder. Contact your network administrator for assistance.
Serial port is not working as expected.	Verify theRS232 Settingson theSettingspage. Flush the serial port on theSettingspage if another device is connected.Connecting the Tx and Rx pins on the RS232 connector creates a loopback that could also help when troubleshooting.

Series Default Local/Host Play Troubleshooting Screens

This section shows and defines the status screens displayed by N2x51 Series devices.

FIG. 58 Host Play Screen

Displayed when Decoder.... ...and Encoder.... Notes
• is set to view an Encoder stream on the network	• is set to Host PI• does NOT have a valid input video signal	Seeing this screen means that the Decoder CAN communicate with the Encoder across the network. It is a good way to troubleshoot network communication between segments using only Encoders and Decoders (without the need for source video into an Encoder).

FIG. 59 Local Play Screen

Displayed when Decoder.... Notes
• is set to LocalPlay mode	If the Decoder is NOT set toLocal Playmode, this screen could signify a network communication issue.

FIG. 60 Unsupported Input Resolution Screen

Displayed when Decoder.... ...and Encoder.... Notes
• is set to view an Encoder stream on the network	• is being fed a video resolution that it does not support	This screen can be useful to show you that the Decoder is receiving the stream from the intended Encoder. However, the video signal being sent to the Encoder is not supported.Please visit amx.com and refer to the product pages for the supported resolutions lists.

FIG. 61 Restricted Content Not Supported Screen

Displayed when Decoder.... ...and Encoder.... Notes
• is receiving a stream from an Encoder• is connected to a monitor that does NOT support Restricted Content (i.e., the monitor is NOT HDCP compliant)	• is transmitting HDCP-protected content to the Decoder	Once the Decoder detects that the monitor is not HDCP compliant, this screen is displayed. If you suspect that this message was displayed in error, please call Technical Support.

NOTE: The Encoder must first be set up to pass HDCP-protected content.

FIG. 63 Video Encrypted Screen

Displayed when Decoder.... Notes
• is receiving a stream from an Encoder it can not decrypt	Make sure the Decoder has the correct password for decrypting the stream. To reset the password, go to the Security page on both the Encoder and Decoder and click the Reset button. Refer to the Security Page section on page 57 if you are not sure where to find this setting.

Appendix A: Minimum Network Requirements

The following list specifies the minimum network requirements that must be considered when deploying your equipment. These requirements cover the necessary protocols and features needed to drive an N2x51 stream.

NOTE: Specific configuration recommendations are based off of the Cisco Catalyst series, however this may vary.

1. Managed Network Switch

2. Gigabit Ethernet (N1000/2000 Based Systems)

3. Internet Group Management Protocol (IGMP) Version 2

• IGMP Snooping
  • IGMP Snooping Querying

☐ Network must include at least one IGMP Querier to maintain stream connections. It is recommended to have all capable switches with the querier enabled and allow IGMP auto-elect to determine the Designated Querier (DQ).

☐ Query interval – 30 seconds. This is the interval between sending IGMP general queries.
☐ Query Response Interval – 10 seconds. This is the maximum time the system waits for a response to general queries.
☐ Last Member Query Interval – 100 milliseconds. This is the interval to wait for a response to a group specific or group-and-source-specific query message.
☐ Immediate Leave (also know as Fast Leave, etc. depending on switch manufacturer).

NOTE: If Immediate Leave is disabled, set IGMP Robustness to Default 2. Robustness can be adjusted generally from 2-10. The higher the value, the more leave latency is added.

- Warnings/Notices

☐ There is a known behavior within IGMP that Encoder streams, whether requested across an uplink or not, will be requested by the DQ and will be present on all uplinks between the stream source switch and the DQ.
- This means that even though you may not be routing a stream to another switch, the DQ's request still puts the stream on the uplink. Therefore, it is important to account for all streams forwarding to the DQ.
- The presence of a multicast router with PIM-Sparse configured to handle the multicast traffic may eliminate or limit this behavior.

4. TCN Flood Off

TCN flood protocol will cause unnecessary backplane and bandwidth usage when adding or removing a device on the network. This can cause stream interruptions as the flooding sweeps through the network.

Should you encounter any problems not covered by these guidelines, please contact technical support via email ([e-mail]) or call 256.461.7143 x9900.
