Getting Started
The NK-VRC Virtual Routing Core provides virtual routing and resource management capability to an NK Series
routing switcher system.
Features and Components
The NK-VRC provides the following features:
• virtual routing for a complex NK Series routing switcher system
• up to 1000 virtual source mappings to physical inputs
• up to 1000 virtual destination mappings to physical outputs
• resource management
• four status LEDs for status/error indications
• compact 1 RU design
• software is fully upgradeable using DashBoard.
• slim modular design integrates with NK Series devices via T-Bus using straight CAT5 Ethernet cables
Typical System Equipment
The NK-VRC is used when you require virtual routing or resource management. Using DashBoard, you can map
inputs and outputs from routing switchers through to the NK-VRC for control via any remote control panel. These
parameters can be saved in a configuration file (.cbd) and sent to an NK-VRC at any time using DashBoard. The
SmartPaste function can also be used to quickly duplicate a configuration file or device configuration to another
device. Therefore, if an NK-VRC is used in a number of different operating scenarios, the configuration can be
changed easily and quickly.
Typical equipment in an NK Series routing switcher system where an NK-VRC would be used includes:
• one or more NK Series routing switchers
• an NK-IPS Network Bridge
• control panels and devices (i.e. RCP-NKM, RCP-NKQ, NK-3RD)
• a PC running DashBoard
• standard source and destination equipment (i.e. cameras, VTRs, servers)
• optionally, one or more external resources (i.e. openGear DA card, GearLite up-converter)
If you are connecting the PC directly to the NK-IPS, use a crossover CAT5 Ethernet cable.
If you are connecting the PC indirectly via an Ethernet switch to the NK-IPS, use a straight-through CAT5
Ethernet cable.
The NK-IPS and PC with DashBoard are only required for setting up the configuration file, then sending this to
the device. However, you can use the NK Switchboard feature in DashBoard to control and monitor a routing
switcher system.
System Overview
A routing switcher system may use distributed control across the Internet, a LAN, or a VPN. The routing switcher
system shown in Figure 2.1 has been simplified. The NK-VRC enables you to map physical inputs and outputs
across multiple router levels to a virtual source or destination. For example, in Figure 2.1, Camera 1 provides
inputs to the SDI router level and the AES/EBU router level. If you map these two inputs to the same virtual source
(call this Camera 1), you can switch both levels with a single switch request. Without virtual routing, this can be

example of virtual routing. You can build up a complex map of several different physical devices that become one
virtual device. When a switch request is made for a virtual device, all the physical devices that are mapped to the
virtual device are switched.
Figure 2.1 Layout showing a simplified routing switcher system with an NK-VRC
When changes are made to the configuration of a device, the changes are not activated in the device until the
configuration file containing the changes is sent to the device. You can save a configuration file, but it will not be
loaded to the device until it is sent to the device. Once a configuration file has been sent to the device, the NK-VRC
operates transparently, mapping virtual switch requests from a remote control panel to physical switch requests for
the routing switchers.

Resource Management
Resource management is a function of a router control system that enables routing of signals between different
router types (such as analog and digital). This is done by using resources to convert from one format to another
(such as an analog to digital converter).
Resource management simplifies the operation of a router system by routing signals through a resource from one
router to another, without requiring the user to know which source and destination to which the resource is
connected. Once configured, the system will be able to automatically find the path between routers. Another
application for resource management is when a limited number of tie lines are to be shared between routers.
Multiple resources can be managed to enable more than one signal path between routers.

An effective routing switcher system requires careful planning. A complex routing switcher system can be easily
mapped using an NK-VRC. All that is required is:
• a list of all the source and destination equipment and resources, identified as virtual sources or destinations
• the inputs and outputs that are physically connected to each routing switcher
• the level of each routing switcher
The following process for setting up the NK-VRC is recommended:
14 • Getting Started NK-VRC User Guide (v05)
Figure 2.3 Flow chart for setting up the NK-VRC
Communication Overview
The control panels and devices send a virtual switch request message to the NK-VRC. The NK-VRC translates this
virtual request to physical requests, then sends these to the routing switchers. The routing switchers recognize the
requests, set the crosspoints, then send physical responses to the NK-VRC. The NK-VRC translates these physical
responses to virtual responses, then sends these to the control panels and devices.
Data Storage
The control panels and devices store information on the menu, destination, level, breakaway, and machine control
status. The routing switcher stores the crosspoint status in its internal memory. The NK-VRC stores mapping
information that correlates virtual sources and destinations with physical inputs and outputs, and the virtual status.
When the
panels
switchers to match the stored virtual status, and also sends the virtual status to the control panels and devices.
Establishing the virtual status may take several minutes, especially if the mapping table has many entries for
routing switcher system is powered up, the routing switcher restores its crosspoint status. The control
and devices request the status of the routing switcher via the NK-VRC. The NK-VRC switches the routing
unassigned crosspoints.

Physical Installation
This chapters provides an overview of the front and rear panel features, and instructions for physically installing the
NK-VRC.
Unpacking the Equipment
On receiving your NK-VRC, check the contents against the packing list. Make sure that all equipment itemized on
the packing list is present and that there are no signs of damage before you start installing the NK-VRC into your
system.
If anything is missing or damaged, contact your Ross Video office immediately to obtain the correct warranty
service procedures. This ensures prompt assistance, minimal turnaround time, and avoids any freight issues.
We recommend that the equipment be installed by qualified and experienced personnel, to any relevant standards
and approvals.
General
These installation guidelines assume the following:
• The relevant NK Series equipment has been installed into a ventilated rack frame. The relative humidity in the
environment of the equipment should be < 70% (non-condensing).
• The routing switcher system has been well planned and designed. Consideration must be given to inputs and
outputs across multiple router levels, and typical operating scenarios for breakaways.
• Correct IP addresses have been assigned to the equipment, where required.
• The routing switchers are connected to the appropriate sources and destinations.
• All NK Series equipment connected in the routing switcher system have software v2.00 or later. Software
updates are available through Ross Video Technical Support.
• If resource management is to be used, the external resources are installed and operational as per the manufacturer
instructions.
The NK-VRC provides phantom power via the T-Bus connector to certain other NK Series devices (NK-GPI,
NK-SCP/A, NK-SCP/K2). The NK-VRC does not receive power via the T-Bus connector.

Mapping Physical Inputs/Outputs to Virtual Sources/Destinations and Defining Classes
The Physical Map tab is used for mapping the virtual sources and destinations to physical input and output ports on
one or more router levels.
NK-VRC User Guide (v05) Setting Up the NK-VRC • 23
Page 24
Figure 4.8 Example of the Physical Map Tab
Destinations – the page numbers for the destinations. Selecting a page number opens the physical destination
mapping table of the selected destination page.
Sources – the page numbers for the sources. Selecting a page number opens the physical source mapping table of
the selected source page.
Edit – click this button to open the Edit Source/Destination Mappings dialog box. This dialog box serves as a
shortcut for populating or clearing the mapping table.
MC Level – use this list to select the machine control level.
Class – these designations are used by the resource management rules to determine when to make a complex switch
using a resource.
Levels (Ln) – these designations are labeled across the column headings. These represent the physical router levels
that have been set in the routing switcher system.
Pages
The Physical Map tab has 10 pages of sources and 10 pages of destinations that can be defined. Each page contains
100 virtual sources/destinations. These virtual sources/destinations are numbered consecutively over the 10 pages.
For example, page 1 of the sources contains virtual sources 1 to 100 down the left-hand column, and page 2 of the
destinations contains virtual destinations 101 to 200 down the left-hand column. Therefore, up to 1000 virtual
sources and 1000 virtual destinations can be assigned.
All of the information contained in the source and destination pages forms the mapping table for the NK-VRC.
To map physical inputs and outputs to virtual sources, destinations, and classes
1. In DashBoard, open the NK-VRC interface.
2. Select the Physical Map tab.
3. Select a
Sources page number.
4. Using a system plan as a guide, determine the first virtual source and router level to map.
5. Enter the number of the physical input port on the routing switcher in the cell that corresponds to the virtual
source number and the router level.
For example, using the information presented in Figure 2.1, the input from virtual source 1 (Camera 1) is
connected to the SDI video routing switcher (level 2) on input connector 13. Therefore, enter 13 in the cell that
24 • Setting Up the NK-VRC NK-VRC User Guide (v05)
Page 25
intersects the virtual source 1 row with the L2 column in the mapping table. Note that it is not necessary for the
virtual source number to match the physical input port number.
6. Repeat the process in Step 5 for the remaining virtual sources.
For example, using the information presented in Figure 2.1, the mapping table for Sources 1 in DashBoard is
as follows:
7. If resource management is being used, select a class number (or pre-configured Class name) in the class list for
each virtual source and destination to represent the signal type. For example, Class 1 = HD, Class 2 = SD, Class
3 = Analog Video, etc.
If resource management is not being used, set the Class cell values to 0.
8. Repeat steps 3 to 7 for the virtual destinations.
For example, using the information presented in Figure 2.1, the mapping table for Destinations 1 in
DashBoard is as follows:
Use of destination port values that do not map to valid outputs on a physical router frame can interfere with
proper system operation. For best results, ensure the values in the level columns of the destination configuration
table include only router frame output port numbers that are present in the system.
9. Click
Send Configuration to update the settings (see “Sending the Configuration to a Device” on page 21).
Edit Source/Destination Mappings
The NK-VRC contains mapping information for 1000 virtual sources and 1000 virtual destinations across 32 router
levels. Conceivably, up to 64,000 cells could need to be modified. The Physical Map tab provides an easy method
of populating the mapping table by using the Edit Source/Destination Mappings dialog box.

• The check boxes in the Used column are not selectable in DashBoard. The Used check boxes indicate if a
resource is currently part of a selected complex switch.
• The check boxes in the Deallocate column are selectable in DashBoard. If selected, and the configuration is then
sent to the NK-VRC (see “Sending the Configuration to a Device” on page 21), the resource will deallocate
from the complex switch and take the park source if assigned (see “Configuring Park Sources” on page 29).
Configuring Park Sources
The NK-VRC uses park sources to “park” resources and destinations when de-allocated. It is a method of
communicating to the NK-VRC which source to send to de-allocated resources and destinations. User definable
park sources for each class can be routed to the inputs of free resources and de-allocated destinations accordingly.
To set up a park source
1. In DashBoard, open the NK-VRC interface.
2. Select the Parks tab.
3. In the Park Source field, enter a virtual source that will be routed to the input of a de-allocated resource or
destination with that class definition.
4. Click
Send Configuration (see “Sending the Configuration to a Device” on page 21).
Configuring Resource Rules
User definable resource rules control which resource type to use when switching from a particular class to another
class. For example, resource type ADC will be used when switching a source with an analog class to a destination
with a digital class.
To set up a resource rule
1. In DashBoard, open the NK-VRC interface.
2. Select the Res Rules tab.

Configuring Control Panel/Device Priorities
All control panels and devices (panels and interfaces through the NK-IPS) have an assigned priority. This dictates
the priority of requests if there are a limited number of resources available.
Every T-Bus device, including the NK-IPS, requires a unique address. Addresses range from 1 to 255. Default
addresses are set to the last two digits of the serial number, plus 100.
There are eight priority levels. Level 1 has the highest priority and level 8 has the lowest. The default level is 8.
Priority assignment is based on the T-Bus address of each panel or device.
To assign a priority

Operating the NK-VRC
The NK-VRC operates transparently between all remote control panels, controlling devices (NK-GPI, NK-JBX),
and the routing switcher system. There are four LEDs and a reset port on the front panel of the NK-VRC.
General
Remote control panels are used to switch virtual sources and destinations, therefore, the keys on the remote control
panels should reflect this virtual context.
If resource management is in use, the panels with a display will indicate when a resource is in use. Additionally,
control panels can be configured to have a resource de-allocate button to manually release a resource that is in use.
For More Information on...
• control panels, refer to the user guide of the respective control panel.
Resource and Panel Priorities
Each resource has a priority assigned to it. This can be used to reserve it for high priority use.
Similarly, each panel or control device has a priority assigned to it that determines which resources can be accessed
by that panel/device.
Resources and control panels can be assigned a priority from 1 to 8, where 1 is the highest priority and 8 is the
lowest priority. If priorities are not required, set all the priority levels to be the same. The default is 8.
In order for a control panel to be able to access a resource, it must have a priority higher than, or equal to, the
resource priority.
A resource can only be de-allocated by the control panel that originally allocated the resource, or by another panel
with a higher priority. The NK-VRC de-allocate function in DashBoard has the capability to de-allocate any
resource regardless of which panel allocated it originally.
LED Indicators
The front panel of the NK-VRC has four LEDs. During startup, these LEDs flash five times to show that they are
functional and to indicate that the NK-VRC is initializing.
During normal operation, the LEDs indicate the flow of requests and responses between the remote control panel
and the routing switcher.
Table 6.3 LED indicators on the front panel of the NK-VRC
LED Function
A Shows that a virtual switch request has been received at the NK-VRC from a remote
control panel.
B Shows that a physical switch request has been sent from the NK-VRC to a routing
switcher.
C Shows that a physical switch response has been received at the NK-VRC from a routing
switcher.
D Shows that a virtual switch response has been sent from the NK-VRC to a remote control
panel.

The LEDs operate sequentially. LED A illuminates when a switch is requested on the remote control panel. LED A
switches off when LED B illuminates, indicating that the virtual switch request has been processed to a physical
switch request and sent to the routing switcher. LED B remains illuminated until the NK-VRC receives a physical
response from the routing switcher that the switch has been made; LED C illuminates at this point. LED C switches
off when LED D illuminates, indicating that the physical switch response has been processed to a virtual switch
response and sent to the remote control panel. LED D switches off automatically after a short delay.
When a successful switch request is made from a remote control panel that is working in a routing switcher system
with an NK-VRC, the LEDs illuminate rapidly from A through D.
Resource Usage
In the Resources tab of the NK-VRC in DashBoard, the Used column indicates when a resource is in use. If the
Used check box is selected, the resource is in use.
Resources can be de-allocated using the Resources tab.
To de-allocate a resource
1. In DashBoard, display the NK-VRC interface.
2. Select the Resources tab.
3. Select the Deallocate check box of the resource.
4. Click
Send Configuration (see “Sending the Configuration to a Device” on page 4–21).
Resetting the NK-VRC
To return to a known operating state and configuration, perform one of the following:
• send the default configuration to the NK-VRC (see “Sending the Configuration to a Device” on page 4–21)
• reset the device
If the NK-VRC fails to accept any configuration that is sent to it, then the device should be reset. When performing
a reset, the NK-VRC takes on the last-known operating state and configuration that is stored in memory.
Reset Button
The RESET button can be used in the event of device failure where the Heartbeat stops pulsing. In some cases,
looping or daisy-chaining too many devices on one line may cause a communication failure or a power dropout
(with devices that are supplied phantom power via the T-Bus line).
The reset button can be used as a last resort if errors are encountered, but no physical problem can be sourced
(disconnected or severed CAT5, power cable, etc).
To reset the NK-VRC
• Press and hold the RESET button on the front panel of the NK-VRC for three seconds.

Glossary
The following terms are used throughout this guide:
Breakaway — an act of performing a switch on only some of the signals grouped together under one label.
Connection Point — setting to define a communication connection between an NK-VRC and a device in the
routing system.
Crosspoint — a switch within a matrix. For example, the connection of signal IN 1 to OUT 1 requires one
crosspoint.
Destination — a label applied to a router output (or group of outputs).
Hard Panel — a physical hardware panel of buttons that is used to control the routing system.
IP Address — a setting that defines the Internet protocol address of a device within a network.
Label — text that is used by control displays to identify a signal as an input or output.
Level — refers to a section of a routing system. For example, a video router would be one level and an audio router
would be a second level.
Logical (virtual) Label — a name for a group of routing system inputs or outputs.
Logical (virtual) Routing — the action of switching a group of otherwise unrelated signals via a common label
(name).
Macro — a recorded sequence of Remote Control Panel operations (local to the panel).
Map — a table that defines the allocation of names (labels) to router input and output sockets.
Matrix — the part of the routing system that performs the actual signal switching tasks.
Partition — matrices may be partitioned to behave as smaller independent matrices.
Remote Control Panel (RCP) — a physical hardware panel of buttons that is used to control the routing system.
Salvo — a system wide sequence of matrix control operations and crosspoint actions.
Soft Panel — a DashBoard interface that represents a panel of buttons that is used to control the routing system.
Source — a label applied to a router input (or group of inputs).
T-B us — the Ross Video proprietary routing communication method via a defined physical interface.
