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 inputs, two 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.

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. Ta b le 3 5 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.

Appendix C: Minimum Network Requirements

N7142 User Manual

Appendix C: Minimum Network Requirements

As you look into an N-Series solution and try to decide what type of network topology and infrastructure will be best suited for your application, there are some minimum network requirements that must be considered when choosing the hardware to deploy a Networked AV system. The requirements presented in this guide cover the necessary protocols and features needed to drive an N-Series stream.

NOTE: Specific configuration recommendations given in this document are based off of the Cisco Catalyst series switch. These recommendations could vary from manufacturer to manufacturer.

1. Managed Network Switch

2. Gigabit Ethernet (N1000/N2000 Based Systems)

3. Internet Group Management Protocol (IGMP) Version 2 a. IGMP Snooping

i. Snooping must be enabled on all switches that are communicating with the querier.

b. IGMP Snooping Querying

i. Network must include at least one IGMP Querier to maintain stream connections.

1. It is recommended to have all capable switches with the querier enabled and allow IGMP auto-elect to determine the Designated Querier (DQ). a. DQ is determined by the lowest IP addressed switch, but can be manually assigned. However, this would

ii. Query interval – 30s

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

3. Some manufacturers do not have Immediate Leave as an option and use Fast Leave instead.

vi. Optional Protocols

1. IGMP Robustness – Default 2

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

2. A good rule of thumb, when planning for bandwidth considerations on uplinks, is to not exceed 80% of the

3. Multicast routing capabilities on each switch (configured for PIM-SM and with an established rendezvous point)

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)

need to be manually configured on all switches to bypass the auto-elect.

you will not be able to have both Immediate Leave and daisy chaining in the same VLAN.

a. Fast Leave does not guarantee an immediate leave from the multi-cast group and can affect switching

speeds and performance.

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.

will still put the stream on the uplink. Therefore, ensure that you have accounted for all streams forwarding to the DQ.

uplink’s total bandwidth capacity to give plenty of overhead for spikes and additional traffic.

can be designed to limit or mitigate this behavior.

Appendix C: Minimum Network Requirements

N7142 User Manual

a. 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

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.

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.
