Introducing Your New N7142 Room Switcher
Chapter 1: Introducing Your New N7142 Room Switcher
Product Overview
The SVSI N7142 Presentation Switcher provides low-latency Networked AV distribution. Designed for professional AV integration,
this unit has six local video inputs, two video outputs, and two available slots for any SVSI networked AV cards to support the best
codec for the application.
The four 4K60 HDMI inputs and two VGA inputs can be independently switched between two scaled HDMI outputs. Each of the two
outputs has a mirrored HDMI port so that the output can be sent to an Encoder card, a second display, or other video distribution
equipment.
The N7142 also has extensive audio support, with a built-in DSP and 60W stereo amplifier capable of operating in 4Ω/8Ω, 70V, or
100V modes. In addition to audio from the HDMI inputs, the N7142 has six independent balanced stereo inputs and two
independent microphone inputs with phantom power.
There are two models of the N7142. The NMX-PRS-N7142 is the base Presentation Switcher, with two available Networked AV slots
that can be populated with Encoder and Decoder cards as required by the application. The NMX-PRS-N7142-23 is an identical
Presentation Switcher, pre-populated with one N2312 Encoder card and one N2322 Decoder card, making it perfect for costsensitive 4K video distribution applications.
Common Applications
While the N7142 is priced right for any design requiring the need of a presentation switcher, the two available Networked AV card
slots make it the perfect presentation switcher for active learning environments, or campuses where overflow support is required.
Integrating the N7142 into a classroom is extremely simple, requiring only web page configuration to set up the system. The
N7142 has Panel Builder built-in so that mobile device UIs can be created to control the switcher from anywhere in the room
(assuming that the mobile device has wireless access to the same network that the N7142 is connected to). The built-in, six-port
managed switch allows the N7142 and the two Networked AV cards to be connected to the LAN with a single network drop.
Features include:
4K60
4:4:4 Video Switching – Switch and display 4K video sources without compromising video quality.
HDMI
2.0 and HDCP 2.2 Support – By incorporating HDMI 2.0 and HDCP 2.2, the N7142 is compatible with all the latest 4K
sources and displays.
Integrated
Networked AV Slots and Gigabit Ethernet Switch – Distribute video in active learning environments or to
overflow locations using built-in Networked AV technology. The Networked AV card slots are designed to support the
existing Encoder and Decoder cards. The built-in switch provides PoE+ on three of its six ports.
Built-in
Audio Amplifier with 4Ω/8Ω, 70V, and 100V Modes – Having built-in support for all three amplifier modes simplifies
purchasing and sparing decisions.
Front
Panel Control – Provides a cost effective, simple solution for selecting inputs without the need for an auxiliary control
system.
Panel
Builder Built-In – Operate the N7142 using a tablet from anywhere in the room.

Appendix B: NetLinx Control
Introduction
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. Now equipment in our latest N-Series Networked
AV Product comes equipped with NetLinx support. This addendum introduces the new configuration aspects necessary to bring all
of your NetLinx-compatible equipment up to speed with the latest functionality. This addendum covers NetLinx functionality as it
applies to AMX’s N-Series product line and is designed to be used as a supplement to additional product documentation found on
our website at http://www.amx.com/techcenter/.
Special Considerations
Netlinx operation requires multicast groups that may conflict with specific video stream numbers. When using Netlinx you must
avoid these stream numbers to ensure proper operation:
• Multicast Mode
• Non-interleaved: Avoid streams 31482 and 31483.
• Interleaved: Avoid streams 32125 and 32126.
NetLinx Configuration Using the Unit’s Webpage
From any main page of the unit webpage, click the NetLinx tab. See Figure 55. Table 35 provides descriptions for each
configuration option.
NOTE: For instructions on how to log in to your unit for the first time, please see the Quick Start Guide (provided in shipment) or visit
our website to view the unit’s user manual.
Choose NetLinx to access these
configuration options.
Configuration options available will depend
on which Master Mode you choose. See

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 NSeries 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 <DEV>, ’setSettings:ircmdtime:<time in ms>’
• 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 <DEV>, ’setSettings: irc2rtime:<time in ms>’
• The default value is 90 ms.

1. Interval between sending IGMP general queries.
iii. Query Response Interval – 10s
1.
The maximum time the system waits for a response to general queries.
iv. Last Member Query Interval – 100ms
1. The interval to wait for a response to a group specific or group-and-source-specific query message.
v.
Immediate Leave (required for N1000, N2x51 4K, N2300 4K, N2400, and N2x35 [Extreme Quality] Low Latency
Models)
1. Used to immediately break up multi-cast groups when a leave message is received.
2. Immediate Leave will break any daisy chaining of multiple units together with a single home run and as such
you will not be able to have both Immediate Leave and daisy chaining in the same VLAN.
3. Some manufacturers do not have Immediate Leave as an option and use Fast Leave instead.
a. Fast Leave does not guarantee an immediate leave from the multi-cast group and can affect switching
speeds and performance.
vi. Optional Protocols
1. IGMP Robustness – Default 2
a. Robustness can be adjusted generally from 2-10. The higher the value, the more leave latency is added.
b. This protocol is effectively inactive when Immediate Leave is enabled.
c. Warnings/Notices
i.
There is a known behavior within IGMP V2 that Encoder streams, whether requested across an uplink or not, will be
requested by the DQ and will be present on the uplinks of all switches between the stream source switch and the DQ.
1. Essentially this means that even though you may not be routing a stream to another switch, the DQ’s request
will still put the stream on the uplink. Therefore, ensure that you have accounted for all streams forwarding to
the DQ.
2. A good rule of thumb, when planning for bandwidth considerations on uplinks, is to not exceed 80% of the
uplink’s total bandwidth capacity to give plenty of overhead for spikes and additional traffic.
3. Multicast routing capabilities on each switch (configured for PIM-SM and with an established rendezvous point)
can be designed to limit or mitigate this behavior.
ii. When a multicast host leaves a group, it sends an IGMP leave message. When the leave message is received by the
switch, it checks to see if this host is the last to leave the group by sending out an IGMP group-specific or groupand-source specific query message, and starting a timer. If no reports are received before the timer expires, the
group record is deleted and a report is sent to the upstream multicast router/querier switch. Lower interval times
will increase bandwidth utilization slightly as querying will happen more often.
4.
Protocol Independent Multicast (PIM)
a. Used to route multicast between VLANs
b. PIM Sparse Mode (PIM-SM)
i.
Recommended for use with N-Series multicast products.
ii. PIM-SM uses a pull model to deliver multicast traffic. Only network segments with active receivers that have
explicitly requested the data will receive the traffic.
iii. Requires configuration of a Rendezvous Point (RP).
1. Must be configured by administrator.
2. Similar to the DQ in IGMP.
3. All multicast sources must register with the RP to be able to be routed throughout the network.
c. Other PIM modes – not recommended for N-Series
i.
Dense Mode (PIM-DM)
ii. Bidirectional (bidir-PIM)
5.
Jumbo Frames Enabled (For N2300 Series)
74
Appendix C: Minimum Network Requirements
a.
N7142 User Manual
The N2300 Series Encoders and Decoders produce a frame payload larger than 1500 bytes. This requires the switch to
have the capacity of handling jumbo frames enabled.
6.
Quality of Service (QOS): Managing the delay, delay variation (jitter), bandwidth, and packet loss parameters on a network
becomes the secret to a successful end-to-end business solution.
a. Not required for use with N-Series devices
b. Policing
i.
A policer typically drops traffic.
ii. Differentiated Services Code Point (DSCP) values can be configured in N-Series devices if QOS is required on the
network.
c. Shaping
i.
A shaper typically delays excess traffic using a buffer, or queueing mechanism, to hold packets and shape the flow
when the data rate of the source is higher than expected.
ii. Cannot be used with N2300 series.
7.
TCN Flood Off
a. TCN (Topology Change Notification) flooding will cause unnecessary backplane and bandwidth usage when adding or
removing a device on the network, which can cause stream interruptions as the flooding sweeps through the network.
i.
Note that this command has to be assigned individually per port that is assigned to that VLAN. However it is not
necessary with ports on the same switch that will not be set up on the same VLAN as the N-Series devices.
b. Command Example: NO IP IGMP SNOOPING TCN FLOOD
