Introducing Your New N2151/N2251 4K Devices
Chapter 1: Introducing Your New N2151/N2251 4K Devices
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-formpluggable (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

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

Installing and Configuring Your AV Equipment
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)
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 conf igure 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.

subnet mask. Contact your network administrator if you are unsure of how to conf igure 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.

Step 3: Connecting Encoders to the Network and Conf iguring 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 the12V 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
4.
Find your Encoder in the list. N2X51 units are displayed on the following tabs:
• Unit Management tab — N2X51 units have N-Series 4K Encoder/Decoder listed in their Type fields.
• 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 conf igure one Encoder at a time. All Encoders come preconf igured to use stream 1. As you add Encoders to the network, you will need to set them up to use different streams.

7.
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.

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 Conf iguration
Options section on page 24 and the Decoder Conf iguration Options section on page 42.
Step 4: Conf iguring 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).
N2151/N2251 User Manual
17
Installing and Configuring Your AV Equipment
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
4.
Click the Trial Save button.
5.
Return to the Settings page through the newly-configured IP address.
6.
Once the Settings page appears (successfully using the new IP address) click the Conf irm 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 f iles)
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 f ile editor (e.g., Microsoft Excel) is necessary to proceed.
4.
The folder containing your CSV file displays. Double-click the file to open it.
5.
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/modif ied version.
6.
Go back into N-Able and select N-Able > Import CSV.
7.
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.

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.
Click Take to apply
changes.

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/slave 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

9.
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).

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.

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 Decoder is currently in Live play mode (its name will display in black text on
the Video Matrix page). You can change to Live mode on the Settings page (see
the Settings Page: Decoder Setup Section table on page 44 for more details).
• Verify network is properly configured and set up. If needed, connect Encoder’s
network port to Decoder to bypass the network.
• Verify that P0 and/or P1 is enabled on the Encoder’s Settings page, next to the
stream number settings. See the Settings Page: Encoder Setup Section table on
page 26 for more details. P1 is disabled by default.
HostPlay screen displays instead of the
video from the source.
• Verify Encoder is in Live play mode (its name will display in black text on the Video
Matrix page). You can change to Live mode on the Settings page (see Settings
Page: Encoder Setup Section table on page 26 for more details).
• Verify source is attached and is outputting a valid signal (HDMI LED on Encoder is
on).
Unsupported Input Resolution screen
displays.
• Change source resolution to a valid resolution (try 720p60).
• Verify cabling is correct.
Copy Protected Content screen displays.
• Contact technical support.
Black screen/no screen displays.
• Set Decoder to LocalPlay. If the LocalPlay screen does not appear, check the
display input settings and cabling. As mentioned previously in this table, you can
change to the Local mode on the Decoder’s Settings page.
• If LocalPlay appears, set Decoder to Live play mode and verify network is
configured properly.
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.

when double-clicking device name on the
Video Matrix page.
When changing the audio type, there are
problems with audio in/out.
• Check the Audio Source (Encoder) and HDMI Audio (Decoder) settings on the
Settings page. 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 to Auto. Set the Encoder to Audio Source > ON
(embedded digital audio on an HDMI connection) and the Decoder to
Enable 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 the RS232 Settings on the Settings page. Flush the serial port on the
Settings page if another device is connected.
• Connecting the Tx and Rx pins on the RS232 connector creates a loopback that
could also help when troubleshooting.

Appendix A: Minimum Network Requirements
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: Specif ic conf iguration 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 groupand-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
(svsisupport@harman.com) or call 256.461.7143 x9900.
