Introducing Your New N2300 Series Devices

Product Overview

The N2300 AV over IP Series belongs to the N-Series product family from AMX and consists of N2312 Encoders and N2322 Decoders. This series provides a flexible, feature-rich, and simple-to-deploy digital media distribution and switching solution that can be used in 4K applications with resolutions up to 4096x2160, with support for HDCP 2.2. This motion-based wavelet codec solution delivers video with nearly imperceptible latency at an incredibly low 200 Mb/s bandwidth allowing 4K distribution over standard gigabit Ethernet networks.

Any source can be sent to one or more displays by routing through layer-2/layer-3 switches using standard Cat5e cable. Standard features include input scaling, bi-directional serial, IR, embedded 7.1 audio, and KVM-over-IP extension. Card versions compatible with the N-Series N9206 card cage are available for high-density applications.

Features include:

• Design flexibility allows you to start as small as 1x1 and grow the system in increments of single sources and devices by simply adding additional Encoders and Decoders.
• Input and output scaling performed in Encoders or Decoders for maximum flexibility.
• Power over Ethernet (PoE) eliminates the need for a local power supply and speeds installation. Units can still be powered locally by 12VDC. This allows easy rack-mountable, high-density installations.
• Infrared (IR) emitter connection allows control of low-cost, IR-only display devices.
• Fast install with Phoenix connectors for power, IR, RS232 serial, and analog audio interfaces.
  • Pass-through HDMI interface allows easy installation with local display, such as desktop PC applications.
  • USB-A and USB-B connections for KVM applications.
• Native NetLinx support provided. NetLinx Studio will easily recognize the device.

Mounting Options

The N2300 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 N9206 Card Cage (sold separately).

Surface and Wall Mounting

To mount your N2300 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 (not included in shipment - part number 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.

Rack Mounting

N2300 Series Stand-Alone Units

A Rack Shelf (part number N9102) accommodates up to two stand-alone N-Series Encoders or Decoders, side by side (mix and match).

FIG. 6 Rack Mounting Stand-Alone Units

N2300 Series Cards

A Card Cage (part number N9206) accommodates up to six N-Series Encoder/Decoder cards (mix and match). The 12V power supply of the N9206 is the primary power source for the installed cards. If the 12V power supply fails or is unplugged, the cards will power down, detect PoE (if provided by switch) and restart normally using PoE. This usually results in a power loss of about one to two seconds. The unit then reboots (which takes another one to two minutes).

To rack mount N2300 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 Rack Mounting 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.

CAUTION: Keep the Card Cage's power cord plugged in at all times so that the internal fans are always running. Not doing so could void the warranty of the cage and all installed cards. Fans are not powered while in backup PoE power mode. 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
• IGMP Snooping
• IGMP Snooping Querier (which only needs to be enabled on a single switch within the network)
• Capable of Jumbo Frames (due to frame density)

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 B: 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. N2300 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.

1. Double-click the wired interface to your AV network, and then click the Properties button.

1. Scroll down in the list to the Internet Protocol Version 4 (TCP/IPv4) option. Highlight it and click the Properties button.

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 a HDMI cable or DVI-D (through adapter). N2300 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 a PoE-enabled switch or an external power supply. Refer to the following steps and Figure 9 for guidance.

1. Using a Cat-5 cable, connect your N-Series Decoder's PO port to a PoE-enabled switch. This provides both network and power connection. In non-PoE applications, connect a 12V regulated power supply (N9312) to the two-pin terminal block plug connector (labeled +12V 2A).
2. 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 the chapter Troubleshooting on page 56 for more guidance.

NOTE: In order for the unit to receive PoE, it must be connected to a switch or other equipment that has a PoE PSE (Power Sourcing Equipment) port. PoE does not pass through the daisy chain (P1) port.

CAUTION: Do not run wiring that is connected to a PoE PSE port outside of the building where the PSE resides. It is for intra-building use only.

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

1. Using a Cat-5 cable, connect your N-Series Encoder's PO port to a PoE-enabled switch. In non-PoE applications connect a 12V regulated power supply (N9312) to the two-pin terminal block plug connector (labeled +12V 2A).

NOTE: In order for the unit to receive PoE, it must be connected to a switch or other equipment that has a PoE PSE port.

1. 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. N2300 units are displayed on the following tabs:

2. Unit Management tab — N2300 units have N2300 Encoder/Decoder listed in their Type fields.
   • Video Matrix tab — N2300 units are found on the N2300 sub-tab (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 2300. As you add Encoders to the network, you will need to set them up to usedifferent streams.

Encoders are listed across the top of the page.

FIG. 11 Video Matrix Page

1. Double-click the Encoder's name in the list. The 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.

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).

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 23 and the Decoder Configuration Options section on page 39.

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 N2300 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 N2300 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 > N2300 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, unplug the N2300, 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 has 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 the N-Able 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.
3. Go back into N-Able and select N-Able > Import CSV.
4. 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. This connection can be digital or analog.
2. Repeat until all Encoders are connected to their sources.

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. 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.
• Upscaling is fully supported.
• Downscaling is supported only if the input is 3840x2160 and the Decoder scaler is set to 1080p50/60. Any other attempts at downscaling are not recommended/supported.

Seamless Switching

The N2300 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 common cell on the matrix, and click the Take button. See Figure 16 for an example.

Enabling this cell causes the Decoder named Conf Rm Dec to listen to the Encoder named 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. N-Series N-Control solutions (N-Command, N-Act, and N-Touch) provide you with the most flexible management options available, insuring you are getting the most from your digital media system.

Primary Control Options

During initial configuration and setup, the free N-Able setup utility (version 2016.11.11 or higher) is sufficient. However, we do not recommend N-Able for production-level, primary-user control.

N-Command Controllers

These web-based hardware Controllers offer intuitive, powerful management of equipment, content, NVR recording/playback, bandwidth utilization, 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 leader / follower 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

The N2300 Series is capable of interfacing with third-party control systems such as Crestron. For direct control of N2300 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 32 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).

NetLinx

NetLinx Studio is commonly used by system programmers to streamline the integration, programming, organization, and support of their AMX equipment. As the cornerstone of AMX's system design software tools, NetLinx Studio offers programmers the most flexible application capable of generating the most sophisticated code possible. Refer to Appendix A: NetLinx Control on page 59 for more information.

KVM Configuration

The N2312 Encoders and N2322 Decoders are KVM-capable. By default, USB connections are disabled.

Basic Setup

Follow these steps for basic KVM configuration:

1. On the N2312 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 N2322 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. For keyboard and mouse combos (with a single connection) use the keyboard port.

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 common cell for the desired Encoder/Decoder streaming combination.

5. Click the Take button to make the change to your matrix. The radio button turns green to indicate the connection was successful.

6. Check the KVM Enable box on the Encoders and Decoders being used (this setting is found on the Settings page).

7. On the Decoder Settings page, enter the KVM Encoder's IP address (in the KVM IP field).

NOTE: Multiaccess is enabled by default, you can have multiple Decoders attached to a single Encoder. Simply go to each Decoder's Settings page and enable KVM and input the Encoder's IP address (or create the connection in N-Able, as described in the steps above).

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.
TX Enable	Enable to broadcast the AV signals. Disable to turn off/stop broadcasting.
Unit Type	Displays the unit type (Encoder or Decoder).
Stream	View/edit the current transmit stream number.	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).
Video Source	Select which input port is encoding video. Choices areAuto, VGA only, and HDMI only.	SelectingVGA onlyorHDMI onlydisables the other video input port.SelectingAutoenables both video input ports. If both audio source types are connected, you cannot define one or the other as the preferred source. Therefore, when inAutomode (and both input types are plugged in) a preferred mode is undefined.
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.
Audio Mute	Enable to stop the transmission of audio data onto the network.
Enable HDMI Audio	Set HDMI audio to be disabled or selected automatically based on the source.	If set toAUTO, the audio follows the video source. If HDMI input is active, HDMI audio is active. If analog video is active, analog audio is active.If set toOFF, audio is disabled.
Save button	Click to save settings made in this section.

Names based on the unit's location and function are very useful. Some good examples are Lobby-Left-VGA (for left side of lobby, VGA input) or CR201-HDMI (for Conference Room 201, HDMI input). Keep in mind the matrices are organized alphanumerically.
Unit Type	Displays the unit type (Encoder or Decoder).
Stream	View/edit the current transmit stream number.	To better understand this setting, think of Decoders dialing up channels on a cable box, rather than a traditional AV matrix. Each decoder can dial in a different active channel.
Audio Stream	View/edit the current audio receive stream number.
Audio Follows Video	Enable to force the Audio Stream to the same as the video stream.
Scaler	Enable to scale outgoing content to a fixed resolution.
Output Mode	Select the output resolution of the video to be transmitted to the video output device (e.g., LCD). The Scaler check box must be enabled for this to be applicable.	Downscaling is supported only if the input is 3840x2160 and the Decoder scaler is set to 1080p50/60. Any other attempts at downscaling are not recommended/supported.
Live/Local	Select live video or locally stored images for transmission to the video output device (e.g., LCD). When video is not available, it automatically goes into local mode.	When video is not available, the most recently played local playlist is displayed.
Audio Mute	Enable to mute output audio.
Lineout Volume	This slider controls the output gain on the analog audio output. By default, it controls both the left and right lineout channels.
Save button	Click to save settings made in this section.

Serial Master Enable	Enable this device to be the server to the designated client.
Serial Client Address	Enter the IP address of the serial client device.
IR Command Holdoff	Set the delay between IR command portions. The default setting is 25 ms.	IR commands are sent in two parts. This setting is the time (in milliseconds) between transmission of part one and part two. The second part of the command is inverted for confirmation purposes.
IR Repeat Holdoff	Set the repeat delay between IR commands. The default setting is 90 ms.	This is the amount of time before a new command is sent. For example, when pressing and holding the volume button on a remote control, this is how long until the command is repeated.
IGMP Joins on Stream Loss	Enable to send Internet Group Management Protocol (IGMP) join messages when no incoming stream is detected.
IGMP Join Interval	Delay in seconds between sending IGMP join messages (if IGMP Joins on Stream Loss is enabled).
Save button	Click to save settings made in this portion of the Advanced section.
Enable SNMP	Enable to allow the device to send Simple Network Management Protocol (SNMP) packets.
Interleaved Multicast Streams	Enables a multicast format which interleaves video and audio streams.	In order for N-Series devices to communicate with each other, their multicast settings must be compatible.
Discovery Packet Transmit	Enable the N-Series multicast discovery service (which is used to identify units).	This is useful for larger network integrations when broadcast packets will not cover the entire network. Enabled by default.
Discovery Interval (secs)	Determine how often (in seconds) the unit transmits discovery packets.
KVM Enable	Enable to allow the ability to share mouse and keyboard over the network. Disabled by default. When disabled, the unit works like a non-KVM unit and ignores any keyboard or mouse activity.

Troubleshooting

This chapter contains possible solutions to some common issues. Should you encounter any problems not covered by these guidelines, please contact technical support via email ([e-mail]) or call [phone]. You can also visit our support webpage at amx.com/support.

Issues	Suggestions
LocalPlay screen displays instead of the stream from the Encoder.	Verify Decoder is assigned to view a valid stream (of an active Encoder).Verify that Encoder and Decoder are on the same subnet.Verify Decoder is currently inLiveplay mode (its name will display in black text on theVideo Matrixpage). You can change toLivemode on theSettingspage (see theSettings Page: Device Settings Sectiontable on page 41 for more details).Verify network is properly configured and set up. If needed, connect Encoder's network port to Decoder to bypass the network.
HostPlay screen displays instead of the video from the source.	Verify Encoder is inLiveplay mode (its name will display in black text on theVideo Matrixpage). You can change toLivemode on theSettingspage (seeSettingsPage: Device Settings Sectiontable on page 25 for more details).Verify source is attached and is outputting a valid signal (HDMI LED on Encoder is on).
Black screen/no screen displays.	Set Decoder toLocalPlay.If theLocalPlayscreen does not appear, check the display input settings and cabling. As mentioned previously in this table, you can change to theLocalmode on the Decoder'sSettingspage.IfLocalPlayappears, set Decoder toLiveplay mode and verify network is configured properly.If screen is black with a slight sparkle effect, verify that your switch has Jumbo Frame support enabled.
No audio is detected.	If there is no audio onallDecoders, 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. SeeSettingUp Your Host Computeron page 12 for more information.
When changing the audio type, there are problems with audio in/out.	Verify that the Encoder'sEnable HDMI Audiosetting is set toAuto.Verify thatAudio Muteis disabled (Encoder and Decoder).
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.	On the Encoder, try setting theVideo Sourceto VGA Only.
Serial port is not working as expected.	Verify theRS232 Settingson theSettingspage.Connecting the Tx and Rx pins on the RS232 connector creates a loopback that could also help when troubleshooting.If NetLinx is enabled, it will take the serial port over.

GET BAUDGet the RS-232 port's communication parameters.	Syntax:SEND_COMMAND,'GET BAUD'Example:SEND_COMMAND 5002:3:0, 'GET BAUD'Command Response:'GET-9600,N,8,1'
SET BAUDSet the RS-232 port's communication parameters.	Syntax:SEND_COMMAND,'SET BAUD,'Variables:baud = baud rates are: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200.parity = N (none), O (odd), E (even).data = 8 data bits.stop = 1 and 2 stop bits.Example:SEND_COMMAND 5002:3:0, 'SET BAUD 9600,N,8,1'Command Response:'SET- BAUD 9600,N,8,1'

Pass Through Commands

For other commands, the NetLinx String command will interpret any existing N-Series API command. For example, to enable the scaler, send the following string command:

SEND_STRING <DEV>, 'scalerenable' 

Similarly, to disable the scaler, send the string command:

SEND_STRING <DEV>, 'scalerdisable' 

The response to a pass through string command is the issued command followed by the status message. For example:

- Command string:

SEND_STRING <DEV>, 'scalerenable' 

- Response string

" 'scalerenable-SVSI_RXGEN2:N225A020000140',A,'NAME:00:19:0B:80:01:BD',A,'MAC:00:19:0B:80:01:BD'..." 

NOTE: Multiple commands cannot be issued together separated by '\r'.

For more information, refer to the API documentation for the N-Series device.

IR Port 2

Using the NetLinx Studio application, download the appropriate IR file to the N-Series device to use the appropriate channels. Port 2 is used to send IR commands. Some tuning of the NetLinx Pulse Time, IR Command Holdoff, and IR Repeat Holdoff on the N-Series device may be required. The Pulse Time is controlled in the SNAPY code. The IR Command Holdoff and the IR Repeat Holdoff are controlled on the Advanced section of the N-Series device Settings web page. See Figure 58 to see where to find these options.

IR Command Holdoff

• This is the delay between IR commands portions.
- To set the IR Command Holdoff, issue the following string command: SEND STRING , 'setSettings:ircmdtime:'
• The default value is 25 ms.

IR Repeat Holdoff

• This is the repeat delay between IR commands.
- To set the IR Repeat Holdoff, issue the following string command: SEND STRING , 'setSettings: irc2rtime:'

• The default value is 90 ms.

Serial Port 3

Port 3 is used for serial commands. Any string sent with the send string command will be output through the serial port. Data returned from the serial port will be from the device also on port 3.

Appendix B: Minimum Network Requirements

The following list specifies the minimum network requirements that must be considered when deploying your N-Series equipment. These requirements cover the necessary protocols and features needed to drive N-Series streams.

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 known as Fast Leave, etc. depending on switch manufacturer).

- Immediate Leave breaks any daisy chaining of multiple units together with a single home run, therefore you will not be able to have both Immediate Leave units and daisy chaining on the same VLAN.

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.
- N-Series Encoders also support separate VLAN tagging of audio and video streams to allow only certain audio and video streams through an uplink in order to eliminate or limit this behavior.

4. Jumbo Frames Enabled

The N2300 Series Encoders/Decoders produce a frame payload larger than 1500 bytes which requires the switch to have the capacity of handling Jumbo Frames enabled.

5. 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.
