Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 9430 Router Module The control system for the Router resides on this module. The control system, discussed at length in Chapter 4: Configuration, is accessed through a web browser interface. The 9430 Router Module provides eight dedicated Input Ports and two dedicated Output Ports. In addition to these Inputs and Outputs, the 9430 provides video thumbnail capture, Test Signal Generation, and Genlock/Timing.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Long Distance Capability Because each Router Control Panel connects to the Router over Ethernet, and because Ethernet reaches much farther than coaxial cable, Router Control Panels can be physically located very far away from the Router if desired.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Quality Control and Signal Monitoring The Flexible Matrix Router can be used for quality control and signal monitoring. In a smaller TV station, for example, personnel in engineering can monitor a variety of channels internally. For a larger facility, someone would be performing dedicated quality control monitoring.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Example Diagram of Complete Router System with All Options Installed The above diagram illustrates one 9430 Router Module with two 9440 I/O Expansion Modules, two 9435 Dual Clean Switch Submodules, and a Router Control Panel (5830). Such an implementation would have 30 Ports and four independent assignable Clean Switches. Each 9440 has 10 bi-directional Ports.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Router Expansion Example for a 21 In x 9 Out Router Configuration The 9430 and 9440 modules combine to form a Router with 20 or 30 Ports. They are joined together by three signal routing backplanes which provide the interconnection between the I/O ports on the 9440 and the 9430 core module. The Router board sets with 20 and 30 Ports install in an Avenue 3RU Frame.

Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Chapter 3: Installation In this Chapter This chapter consists of two parts: Part One: Module Assembly, describes how modules are assembled in the event that you need to add modules or submodules in the future. Original orders are delivered preassembled.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide PART ONE: MODULE ASSEMBLY Original Orders Preassembled For original orders, Ensemble Designs will assemble all modules (the 9430, 9435, and 9440 modules as applicable) before shipping them to your facility. You can then install the assembly into the Avenue frame as a single unit. However, if you add modules at a later time, these instructions will show you how to assemble and install them.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 9435 Dual Clean Switch Option An optional 9435 Dual Clean Switch submodule can be mounted to one or both of the following: • the 9430 Router Module • the 9440 Expansion Module in the Expansion 1 position (the left hand position as viewed from the front of the frame) The 9435 Dual Clean Swith submodule is secured to the 9430 and/or 9440 by screws and threaded stand-offs in four positions.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 9430 and 9435 Fit in a Single Frame Slot Note that the 9435 fits within the slot profile of the 9430, so the combination of the two still occupies a single frame slot in either a 1RU or 3RU Avenue Frame. Detail of a 9435 Clean Switch installed on a 9430 Router Module www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 9440 I/O Expansion Option A maximum of two 9440 I/O Expansion Modules can be attached to the 9430 Router Module, one per side. A 9440 I/O Expansion Module The 9440 I/O Expansion Modules are mechanically attached to a 9430 with screws and stand-offs. The signal electrical connection is made by three high-speed routing backplanes with precision transmission lines designed to support signals up to 3 Gb/s.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Sliding Routing Backplanes through Slots in the 9430 The routing backplanes slide through slots in the 9430 module, picking up electrical connections on each side from these slot connectors. From the top side of the 9430, gently insert the the routing backplanes through the slot connectors. The slot connectors on the 9440s are set back farther from the module edge connector than on the 9430.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Installing Stand-Offs on the 9440 Install the four stand-offs on each 9440 using one screw per stand-off, as shown below. Stand-offs on the 9440 Expansion Module Aligning the 9440 with Routing Backplanes Align the 9440 with the routing backplanes. Gently guide the backplanes into the smaller slot connectors on the 9440. The narrow end of the backplane will be flush with the connector on the 9440.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Example of Completed Assembly The example shown below consists of one 9430 and two 9440s, with backplanes and stand-offs in place, providing 30 ports. This assembly is ready to install in an Avenue 3RU Frame.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Installing the BNC Plastic Overlays On the rear of the Avenue frame, install the BNC plastic overlays provided onto the corresponding group of rear BNC connectors associated with the Router location. The 9440 modules have two plastic overlays, one for the Expansion 1 position and one for the Expansion 2 position.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Digital Signal Connections The digital inputs and outputs of the Router are all equally capable of supporting 3G SDI, HD SDI, SD SDI, DVB-ASI, SMPTE 310M and AES audio signals. Connections to sources and destinations are made with 75 ohm coaxial cable. Cable Length Considerations An important technical consideration in system wiring is the length of the cables that run between different pieces of equipment.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Router Control Connections Although the Avenue Frame system is equipped with both RS-232 and Ethernet interfaces, the 9430 has its own dedicated control connections. The communication bandwidth needed to support the live video thumbnails and the expectation on the part of third-party control systems (automation, event control) for a dedicated control port require this.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Connecting a Timing Reference to the Avenue Frame In order to genlock the video resources in the Router (TSGs and Clean Switches) to a larger video system, connect a timing reference to the Master Reference Input on the Avenue Frame. This is a loop-through connection on the 3RU Frame which requires a termination. On the 1RU Frame it is an internally terminated input.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Router Control Panel Installation Connecting Ethernet Cable to RJ-45 Port Make an Ethernet connection to the RJ-45 port on the rear of the Router Control Panel. The Ethernet cable should be connected to a network Ethernet router or switch to make it accessible to the Router. The Ethernet port will auto-sense cable direction, so a cross-over cable is not needed.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Labeling Buttons The Router Control Panel comes with two button labeling options: 1. Pre-printed key cap inserts, described on this page, and 2. A customizable label template that generates a PDF, described on the next page. First Method: Key Cap Inserts The provided key cap inserts give a broad range of terms and numbers printed on clear plastic sheets.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Second Method: Customizable Label Template You can create your own customized button labels directly from one of your Profiles. (For more information about Profiles, see Creating and Editing Profiles on page 59.) The template draws from the Port names associated with the Profile you choose. This automatically generates a PDF document of precisely scaled and aligned labels that you can print on paper or acetate.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 5. Toward the bottom of the generated label page, click the Print icon. If you do not see this toolbar, move your mouse cursor across the screen. It may not constantly display itself. 6. Cut the printed labels into two strips as shown below.

In the Address field, enter the IP address you want to use for the Router; for example, 10.123.222.100. If you know the Gateway and DNS Server information, enter that information. Entering the IP address you want to use for the Router that suits your own network environment 5. Click Save Changes, then click Done.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Readjusting Controlling Computer’s IP Address to be in Range of Router’s Newly Assigned IP Address Now that you have set the Router’s IP address away from its factory default in favor of an IP address suitable for your own network environment, you must change the IP address of the controlling computer once again so that it is in a compatible range with the Router’s new IP address.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Establishing Initial Control Point and Profile for Administrator Functions Now that you have set the Router’s IP address and subnet mask in a manner that suits your network environment, you can start the configuration process. From the controlling computer, connect to the 9430 to establish an initial Control Point for administrator functions. To Create an Initial Control Point 1.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide 5. From the left navigation panel, click Network. The Network page displays. 6. Set the Gateway and DNS Server parameters according to your network configuration. In general, these settings will be required only in installations with extended networking requirements, such as a remote site connected by VPN. 7. From the left navigation panel, click Control Points. The Control Points window displays.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide To Assign the Factory Default Profile to the Router Admin Control Point You must assign a Profile that defines which sources and destinations this Control Point can access. To begin with, choose the Factory Default Profile. It provides access to the eight Inputs, two Test Signal Generators, and two Outputs of the basic 9430 module. 1. Under Pending Authorization, select FactoryDefault from the Profile drop-down control.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Now that you have set the Router’s IP address, assigned a Profile and authorized an initial Control Point, you have access to all of the Router’s configuration settings. In the example just discussed, the Router Admin Control Point is specific to the controlling computer. Later sections of this chapter discuss how to create additional Control Points for other computers, laptops, iPads, and Router Control Panels (5830).
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Security and Administrative Access to Settings All of the Router’s configuration parameters can be accessed through the Settings button in the upper left corner of the web interface. Without enabling a password, anyone with access to the Router (meaning anyone who has an authorized Control Point with an assigned Profile) can make changes to its Settings.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Configuring the Router's Ports Planning Router Port Configuration Typically, during the planning stage of your Router implementation, you would determine in advance how you want to initially use the router in terms of inputs, outputs, test signals and clean switches. Cabling Router to Match Plan Based on your plan, connect cables to the ports to match your intended use.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Definitions of Port Configuration Choices Port configuration choices are described below, followed by detailed examples. Unassigned For all Port Types A port can be set to Unassigned when it is not in use. This will remove it from the list of Sources and Destinations that can be assigned to a Control Profile.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Secondary TSG For Fixed Output and Bi-directional Ports The Secondary TSG configuration delivers the test signal being generated in the Secondary TSG to an output port, independently of any user control of the switching matrix. Note: As described above, only ports that are configured as Sources or Destinations are available to assign to the Source and Destination buttons on a control panel.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Implementing Router Port Configuration Plan Now that we have covered the background context for numbers and types of Router ports available and what the various configuration selections mean, you are ready to configure the Router’s ports. To Configure the Router’s Ports From the left navigation panel, select Ports. The Ports page displays. Initially, all the ports show “Unassigned” for the Type drop-down control.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide On the Ports page, take the following steps for each port that you plan to use: 1. Select its Type from the Type drop-down control. 2. Indicate a Name (this is the Port’s name that is visible when creating Profiles). 3. If applicable, make a selection from the Follow/Pair drop-down control. 4.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Creating and Editing Profiles A Profile provides each Control Point with a configured view of the Sources and Destinations on the Router. A Profile defines which Sources and Destinations can be accessed from any given Control Point. A Profile also defines the order in which Sources and Destinations display for a Control Point.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Examples of Profiles After the functions of the Ports have been defined, the available Sources and Destinations are selectively assigned to Profiles. Ports that are configured as Follow, Paired, or Unassigned are not available to a Profile since they cannot be “controlled.” Master Control Room (MCR) 10 x 3 In the example below, there are ten Sources and three Destinations for a Master Control Room Profile named “MCR.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide MCR Profile Edited and Reordered to 8 x 3 This Profile has been edited to remove access to two of the Sources (ENG Rx 1 and News 1). In addition, blank spaces have been inserted to organize the selections as they are presented on a control panel. Those “blanks” will produce unused buttons on the panel.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide MCR Profile Edited to 8 x 1 This Profile has been further edited by removing two Destinations. The result is a Profile that allows control over only a single output. If assigned to a Router Control Panel (5830), this would effectively create a single destination panel. An edited Master Control Room (MCR) Profile with 8 Sources and 1 Destination www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Establishing Control Points and Access Authentication There are many ways to control the Router and many possible Control Points. In order to manage these and selectively limit access, each possible Control Point must be authenticated. An administrator grants access to Control Points through configuring the Control Points page.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Examples of Control Points • 5830 Router Control Panel • Laptops, iPads and other computers using a web browser • External control using serial protocols Configuring the 5830 Router Control Panel Configuring the Router Control Panel involves: • Connecting it to the network with an Ethernet cable, • Turning on the power, (unless it is being powered using Power over Ethernet, or PoE), • Determining whether to us

Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Although the 9430 Router Module must use a fixed (static) IP Address, it is possible to operate the 5830 with either a static address or one that is automatically assigned by your network under DHCP. If DHCP is selected from the Address Mode pull-down control, the 5830 will obtain an address from the DHCP server on your network. Our recommendation is to use a fixed (static) IP Address for the 5830 Control Panel. 2.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Creating a Control Point for the 5830 Panel 1. Browse to the 9430 Settings > Control Points page. 2. Under the heading Add Control Point, enter a name for the 5830 Panel in the Name field. 3. Select FactoryDefault from the Profile drop-down control. 4. Enter the IP address of the 5830 into the Address field. 5. Click Add. 6. Click Done.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Configuring Other Control Points For control points other than Router Control Panels, such as iPads and web browsers, there are two methods for adding them. One method is to request access from a Control Point. The other method is to assign an IP address to a Control Point. These two methods are described as follows: First Method: Requesting Access from a Control Point 1.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Number of Control Points That Can Operate Simultaneously The Router performs best with a maximum of four control points operating simultaneously. The Router’s data bandwidth is shared across all of the control points. Each additional control point adds an incremental load on the system. When more than four control points are being used, the Router’s video thumbnail display performance may begin to degrade.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Setting Up Timing and Genlock The 9430 can be locked to a Frame Reference (through the Avenue Frame Master Reference input), or operated from an internal precision reference. The Reference Source control selects between those two choices. The Reference Status indicator displays the status of the currently selected reference.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Note on Frame Rates Despite the large number of video formats supported by the Router, there are only three possible frame rate families. 50 Hz 59.94 Hz 60 Hz The 50 Hz frame rate family includes 25 Hz and 50 Hz frame and field rates. This family includes all of the “PAL” related standards in both standard and high definition. All of the NTSC-derived standards, including 23.98, 29.97, and 59.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Configuring Internal Test Signal Generators The 9430 is equipped with two independent internal Test Signal Generators (TSG). These generators are driven from the genlock source chosen by the Reference Source control on the Timing and Genlock page. Each TSG can be independently configured for format, frame rate, and test pattern. The TSG outputs will always be clock-locked to the reference source.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide The Test Signals configuration page www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide The configuration controls for the TSGs as are follows: Standard Select the desired operating format and frame rate. Note: The choice of Standard for the Primary Test Signal Generator sets the System Frame Rate for the entire Router. This is detailed earlier in the section Setting Up Timing and Genlock on page 70.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Vertical and Horizontal Timing The Vertical and Horizontal Timing controls adjust the timing of the TSG relative to the genlock reference. Setting the H and V parameters to 0 will “zero” time the TSG to the reference. Negative values will cause the TSG to be early with respect to the reference; positive values will make the TSG later in time.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Audio Reference Level This control selects the Digital Reference Level for the audio tone generators. This sets the nominal reference level (or 0 VU for you oldschool folks) relative to Digital Full Scale (DFS). This relationship is expressed on a logarithmic (decibel) scale.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Slate Enable When enabled, the text which has been entered in the Slate Text field will appear over top of the test pattern. Slate Text Enter the desired Slate text in this field, then hit the Tab key or click outside of the Slate Text field. As with all of the configuration settings in the Router, this will be saved in non-volatile memory so that it persists when the Router is powered down.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Switch Point Identification As described in the section Setting Up Timing and Genlock on page 70, the video format and horizontal and vertical timing for the Primary TSG determines timing and location of the switch point in the vertical interval. Under SMPTE RP 168, the switch point varies from one format to another. In general, it should occur during the middle portion of a specific line in the vertical interval.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide When switching away from the TSG output with Switch Mark to a source without, there will be a momentary frame where the switching discontinuity will be visible. www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Working with the Clean Switch Option Each 9435 Dual Clean Switch Option provides two, independent Frame sync/Clean Switches. These resources can be deployed within the Router in a variety of ways.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide If an output port has been configured to Follow a Destination which has a Clean Switch assignment, that port will also deliver the Clean Switch output. That port set to Follow will not be seen as a destination on a control panel because there is still only one Destination. The conceptual effect of this is to have incorporated an output DA (Distribution Amp) into the Router. www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide By assigning a Clean Switch to a Source (input port), it is fed from that port and its output drives the routing matrix. This configuration is particularly useful with an asynchronous source. The frame sync feature of the Clean Switch means that this source will now be synchronous and timed on any output it is switched to. This is essentially the same as placing an external frame sync upstream of that router input.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Clean Switch Configuration There are four sets of configuration controls, one for each of the possible Clean Switches. Each Clean Switch is configured independently. The Clean Switch configuration page www.ensembledesigns.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide The configuration controls for the Clean Switches are as follows: Assign To Assign the Clean Switch to any of the Sources (Input Ports) or Destinations (Output Ports) that have been configured in the Port Configuration menu. Only the currently available Sources and Destinations will be presented as choices in this menu.
Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide Vertical and Horizontal Timing This control adjusts the timing of the Clean Switch relative to the genlock reference. Setting the H and V parameters to 0 will “zero” time the CS, matching it to the reference. Negative values will cause the CS to be early with respect to the reference; positive values will make the Clean Switch output later in time.
