Figure 3.35 Heartbeat Display

NK Series routers indicate their status by a pulsating LED, called a heartbeat. The heartbeat flickers when a switch
message is handled by the router. It dims slightly to indicate a handled message that did not result in a switch.

The heartbeat is also connected to the alarm status. It monitors the status of the power supply and signifies a
problem by pulsating at a noticeably faster rate.

NK Series Router Power Supplies

Each NK router, control panel and control device comes standard with a single external AC/DC power supply. The
exceptions to this are devices that are powered from the T-Bus, such as the RCP-NK1, NK-SCP/A and NK-GPI.

Customizing RCP-NK1 Control Panels

Overview

One of the flexible features of the NK Series of routers and panels is the ability to install RCP-NK1 control panels
either locally or remotely to NK-16 routers. Localizing panels ensures that rack space is maximized and cable
connections are minimized. Remotely installing panels means that panels do not necessarily have to be installed in
the immediate vicinity of the routers, and can be connected and installed in other rooms if required.

Localizing the Panel

If users are localizing control panels, a short (between 12.5 and 20cm or 5 and 8”) standard (not crossover) CAT5
cable is required to connect the panel to the router internally.

Ensure that the router and the panel you wish to localise are not connected to any other devices before proceeding.
Also ensure that both the router and the control panel are disconnected from the power source.

To fit the control panel locally to the front of the router:

1. Remove the front button panel from the case it was originally shipped in.

2. Remove the front panel of the router.

3. Disconnect the wire that connects the heartbeat to the circuit board.

Configuring Routers

USO RESTRITO

Overview

If a simple, standard setup is all that is required, NK Series routers can be used straight out of the box. After
unpacking the NK Series router and connecting the inputs and outputs, the system is ready to go. Where an
alternative configuration is required, the NK-IPS allows unparalleled configuration using the web interface on the
NK-IPS or with Phoenix.

The NK Series routers have an input and output range of 1 to 65535 that can be set on up to 32 levels. Routers may
be configured identically using the web interface on the NK-IPS or with Phoenix, in which case they will switch at
the same time. Routers maintain status for their output range and also retain that status between power down cycles.
Routers also maintain protect information for their output range. A control panel can protect a specified output, if
another device attempts to switch that output, it will be denied.

Routers may be configured to have internal partitions. These are always a factor of the maximum size; for example,
a 32x32 router can be two 16x16 routers, three 10x10 routers, four 8x8 routers, five 6x6 routers, seven 4x4 routers
or eight 4x4 routers. Where there are unused crosspoints due to partitioning, they will be the last inputs and outputs.

Configuration Options — NK-IPS

The router Device Properties page, accessible through the NK-IPS, allows users to configure interface and usability
options for all NK Series routers and also displays the alarm status of the router, as well as having the unique ability
to assign names and brief descriptions for the devices themselves.

For details on how to query devices and use of the NK-IPS, refer to the NK-IPS Internet Protocol Server User
Guide.

Matrix Power

The Matrix Power status alarm indicates the power status of the router. A router that displays any alarm status other
than Green (safe) should be switched off and unplugged. Another power pack can be used to test the router frame
again, but if the status alarm remains on the Device Properties page, a Ross Video representative should be
contacted.

RCP Power

The RCP Power status alarm indicates the power status that the router distributes to the control panels connected to
it. For any alarm status other than Green (safe), panels should be disconnected one by one, and the alarm status
checked. In some instances there may be too many devices connected to the router to ensure regulated power
consumption by each device. If all devices have been disconnected from the router and the alarm status remains
activated, the router should be switched off and unplugged. Another power pack can be used to test the router frame
again, but if the alarm status remains higher than Green on the Device Properties page, a Ross Video representative
should be contacted.

I/O Power (NK-64 Routers only)

The I/O Power status alarm indicates the I/O card status for the router. As NK-64 routers are comprised of 8
separate I/O cards, each card has its own alarm. If any card has a fault or fails during operation, the I/O Power status
alarm will be triggered. If the alarm has been triggered, each input and output card should be checked individually
before using the router for further operations.

Configuring the RCP-NK1 Panel

Overview

All NK Series components are preconfigured and can be used with the factory default setup immediately after being
installed, without the need for additional configuration. Where an alternative configuration is required, the NK-IPS
allows unparalleled configuration using little more than a PC and Phoenix or a web browser.

The RCP-NK1 40 button panel controls NK Series routers, displaying router status, switching and protecting
crosspoints. It has 40 soft, programmable backlit keys, with 8 being physically separate for convenient function key
layout. The LED brightness can be set through the NK-IPS for both on and off brightness.

Each panel is capable of controlling the whole address space for the NK system (1-65535 inputs and outputs on 32
levels). Panels operate in XY mode by default, but can easily be configured to work in dual cutbus mode using the
NK-IPS.

NK Series User Guide (1.0) Configuration • 4–13

Control Panels can be linked together if they have the same address and a different panel link address (that is not 0).

USO RESTRITO

Linked panels behave exactly as if they were one larger panel with the exception that macros can not be appended
or added across panels. The panels communicate using the T-Bus protocol with support for collision detection.

Each key can be assigned a function, with up to 3 parameters (Default, Shift1 and Shift2). This function will be
called when that switch is pressed. The key functions are:

DESTINATION Changes the destination that the panel is controlling. If the DESTINATION KEY is not

active, the default value is selected. When the DESTINATION KEY has been selected
first, the relative destination is selected.

SOURCE Switches the input using the current destination and level pattern. If the SOURCE KEY

is not active, the default value is switched. When the SOURCE KEY has been selected
first, the relative source is switched.

CROSSPOINT Switches the input, output and level/breakaway associated with this key.

LEVEL Toggles this level number from the current level pattern.

BREAKAWAY Selects a preconfigured breakaway level pattern.

BREAKAWAY STEP Steps through breakaways.

MACRO Records key events that can be replayed later.

PROTECT The PROTECT key attempts to protect the currently selected output/level pair.

TAKE The TAKE key confirms input key events. The user sets up a switch, and presses the

TAKE key to activate the switch.

CHOP Alternates between the last two selected inputs.

SHIFT Changes the source or destination page of the panel.

DEASSIGN Allows users to reset a destination assignment.

MACHINE CONTROL Toggles on/off RS-422 Machine Control for reciprocal switching.

PANEL LOCK Locks the panel from all switches or function key operation.

UNASSIGNED Key is not assigned any function or value.

NK Series Operation

Start-up Process

After power has been supplied to the NK Series components, the routers broadcast their status to each other. Panels
also listen to these broadcasts and are able to download the matrix status within this time. Linked panels broadcast
their internal state (shift, destination, levels, take, chop and machine control). Panels will attempt to retrieve the
status for their current output/level pair. Finally panels will request for any protects they may be holding. Any
routers (possibly multiple routers) with a protect held by this address will respond.

Router Start-up

On start-up, the newly connected router will attempt to download status from an operating router with the same
output range and level. It will then switch all crosspoints and broadcast its status. Routers respond to data messages
from other routers to allow this synchronization.

Control Panel Start-up

When a control panel is powered up, the LEDs will light 2 at a time from left to right. It will then fade to a Ross
logo, fade that logo out and fade in the current status. This is to allow time for all connected NK devices to
synchronize on start up.

Panels remember the last selected output and breakaway/level. These will be restored on power up unless
overridden by a linked panel with different values.

Single Panel RCP-NK1 Operation

Overview

The control panel functions detailed below can be programed with the NK-IPS for full functionality. The examples
herein are described using the factory default configuration, loaded with every NK router. For details on the factory

Macro Keys

Macros can be used to initiate multiple switches in one quick key press. Several MACRO keys can be assigned to
one panel and then different macros recorded to each key. When users are required to regularly switch between two
or more static switch assignments, macros can be used to switch these in one easy key press.

A macro is an event playback feature similar to a salvo. A salvo will only trigger a series of switches, whereas a
macro will record a series of events for express playback at a later time. When the macro is played back, it will
activate a sequence of switches to configure the router. Macros can be extremely valuable in minimizing repetitive
key presses by configuring multiple switch events (source, destination and crosspoint) to one key.

A macro event comprises a source, destination, crosspoint, macro or protect key press. When appending one macro
to another, this is counted as 1 event. This is covered in more detail later under the heading Appending Macros.

A MACRO key can store a maximum of 84 events and users can assign up to 40 MACRO keys on the RCP-NK1
panel. It is recommended that users with only a single, unlinked panel only assign two or three keys as MACRO
keys. Users who have several linked panels may find it convenient to have one panel set aside solely for the purpose
of macros and assign as many MACRO keys as is required.

Pressing a SHIFT key when recording a macro does not count as an event, as the macro recorder simply recognizes
that the key that is actually pressed is the relevant source or destination.

defined in the control panel’s Device Properties page of the NK-IPS.

Recording Macros

To record a macro, you first need to start ‘macro recording mode’.

1. Hold down the MACRO key for about three seconds. The MACRO key will flash quickly to indicate that the

panel has entered macro recording mode.

2. Release the MACRO key. The MACRO key will flash slowly to indicate that the panel is in macro recording

mode.

3. Enter the events you wish to record, as you would if you were to activate a switch. Key presses will be

acknowledged by a quick flash on the key you have entered into the macro.

4. When you have finished entering switch events, press the MACRO key to exit macro recording mode.

The MACRO key will stop flashing to indicate the panel has exited macro recording mode.

Example 1

Appending Macros

Appending macros is a feature that allows the addition of more events (or another macro) to an already existing
macro.

To append a macro, you first need to enter macro recording mode, and then enter macro recording mode again to
append the macro.

1. Hold down the MACRO key for about three seconds. The MACRO key will flash quickly to indicate that the

panel has entered macro recording mode.

2. Release the MACRO key. The MACRO key will flash slowly to indicate that the panel is in macro recording

mode.

3. Hold down the MACRO key again (this will play back the macro internally so that it may be appended). The

MACRO key will flash quickly.

4. Release the MACRO key. The MACRO key will again flash slowly to indicate that the panel is in macro

recording mode.

5. Enter the events you wish to record as you would if you were to activate a switch. Key presses will be

acknowledged by a quick flash on the key you have entered into the macro.

6. When you have finished entering switch events, press the MACRO key to exit macro recording mode.

The MACRO key will stop flashing to indicate the panel has exited macro recording mode.

USO RESTRITO

When appending macros or adding one macro to another, if you use a single input or output in more than one
macro, it will override the previous status of that key.

Example

If you wish to add the output status Input 9 to Output 10 to an already existing macro (Macro1 from Example 1 in
the previous heading, Recording Macros) you would follow this sequence of key presses:

Key press 1 Key press 2 Key press 3 Key press 4 Key press 5

Macro1 Macro1

Adding one Macro to another Macro

Adding one macro to another can be useful when you have more than one macro that shares the same output status
(the same source to destination switch assignments) but where one macro also has output status that the other macro
has not assigned.

As the macro function is only an event recorder, other macros are stored as one single event, not the sum of the
events in that macro. Similarly, if a macro that has already been added to another macro is changed, the appended
macro when played back will reflect that change.

Example

If you wish to append Macro1, adding Macro2 to it (from Examples 1 and 2 in the previous heading, Recording
Macros) follow this sequence of key presses:

Key press 1 Key press 2 Key press 3 Key press 4

Macro1 Macro1

In the example above, the Macros are as follows:

Out10 In9 Macro1

Macro2 Macro1

• Macro1 = Input 1 to Outputs 1, 2 and 3, and also sends input 2 to outputs 7, 8 and 9.

• Macro2 = Input 1 to Outputs 4, 5, 6 and 7, and also sends Input 2 to Outputs 8 and 9.

In this example, because Output 7 is used twice, the last status added will be the one used when the macro is played
back. The final status of Macro1 when it is played back will be as such will be:

• Input 1 to Outputs 1,2,3,4,5,6 and 7.

• Input 2 to Outputs 8 and 9.

To cancel recording or appending a Macro

To cancel recording or appending a macro, press the macro key after entering macro record mode.

Macros can not be cancelled after entering events in macro recording mode. If a mistake has been made, you will
have to exit macro recording mode and enter it again to re-enter events you wish to be played back.

Protect Key

The PROTECT key is used to lock current destination from use by other sources, as well as from other linked
panels. The PROTECT key is especially useful in instances where destination must be held after a switch has been
made.

A panel may be locked to prevent unwanted key presses (particularly accidental switches). The Panel Lock is
reflected on the control panel’s Device Properties page of the NK-IPS, and can be locked or unlocked as required
both from the NK-IPS configuration page or from the panel.

To activate the panel lock from the RCP-NK1, follow these steps:

1. Hold down the PROTECT key for about three seconds. The PROTECT key will flash quickly to indicate that

the panel lock has been activated.

2. Release the PROTECT key. The PROTECT key will flash slowly to indicate that the panel is locked.

Example

Pressing the PROTECT key will protect the current destination.

Holding the key again will unlock the panel.

Take Key

A TAKE function key is used to activate the selected switch. First the required destination is entered, then the
required source; the SOURCE key on the panel flashes and the TAKE key illuminates. The switch is activated once
the TAKE key is pressed. The entered crosspoint change will be completed immediately after the TAKE key has
been pressed. This enables the user to preset a crosspoint change before the switch is required. The pending switch
can be aborted by pressing any key other that the TAKE key.

Machine Control Key

The panel may be configured to operate a machine control (RS-422) level. The machine control level will
automatically be switched reciprocally for the source (master) and destination (slave) selected. To execute a
machine control reciprocal switch, press the MC KEY to enable machine control operation (key will be
illuminated) and then press the required destination and source.

Machine control operation is dependent on three settings:

1. Machine Control mode and level options are configured on the control panel’s Device Properties page.

2. Machine Control is enabled (using the MC KEY function key).

3. Current breakaway includes the Machine Control level.

An MC KEY does not necessarily have to be assigned to the control panel to enable reciprocal switching. If the
Machine Control Enabled option is checked on the control panel’s Device Properties page, all switches activated
from the panel will be reciprocal.

An MC Key is required to disable machine control reciprocal switching in multiple slave scenarios.

Linked RCP-NK1 Panel Operation

Overview

When panels are linked together, key behavior remains as above (with single panel system), although the following
details must be noted when linking panels:

• Pressing CHOP will alternate between two sources, including cases when the sources are on different physical
panels.

• Pressing TAKE will activate a take, including cases when the SOURCE key is on a different panel to the TAKE
key.

• If any linked panel has a TAKE key, the linked device enters take mode when a source or crosspoint key is
pressed.

• Locking one physical panel from the control panel’s Device Properties page will also lock all linked panels. The
NK-IPS can be used to unlock panels if required.

• Entering macro record mode causes all linked panels to be in macro record mode, switch events and protects can
be added from different physical panels.

• Macros cannot be appended or added across panels.

• Page SHIFT keys control source and destination pages for the whole linked panel.

• DESTINATION keys control the destination for the whole panel.

• LEVEL and BREAKAWAY keys control the level mask for the whole panel. Breakaway preview is not available
across linked panels.

• If a panel is added to an operating linked panel, the linked panel changes its states in regards to TAKE, PANEL
LOCK and cutbus accordingly.

• If a linked panel is added to an operating linked device that is in TAKE, CHOP, PANEL LOCK, or macro
recording mode, it starts in that mode.

• Menus do not work across linked panels.

NK-SCP/K2 Operation

Implementation of the NK-SCP/K2 means that NK routers can be controlled exactly as if they were a matrix
module housed within the Kondor 2 frame. Switches can be activated by Geneos control panels as well as from a
Virtual Control Panel (VCP) from the Panelworks page in the Geneos software.

When switches are activated from a control panel or VCP connected to the Geneos CPU, the SCP/K2 monitors
commands and converts them to the T-Bus protocol. If the command sent corresponds with a level that an NK
router is occupying, then that level will be switched. If there are no NK routers occupying that level, then the switch
will be performed where that level is occupied, most likely within the Kondor 2.

Switches can be activated from the NK control panel (RCP-NK1) but are not advised as they will not be reflected
within the Geneos CPU status table. If an RCP-NK1 is connected to the router (or T-Bus), any switches activated by
the panel will override the status and commands from the Geneos panels or Geneostat virtual control panels.

Video Referencing

Overview

All NK Video and Audio routers are fitted with a video switching reference input to ensure that switching occurs in
the vertical interval across all levels. Normally, the reference input signal is a color black (Black burst) composite
signal, however it may be any normal composite signal. The NK router will automatically detect the signal as being
either 625/50 (PAL) or 525/60 (NTSC) and automatically adjust the switching pulse to comply with RP 168, line 6
for PAL and line 10 for NTSC.

The NK router switches on frame boundaries. There are two 75 Ω BNC reference input BNCs on each NK router
arranged as a passive loop-through pair. Normally, a single Black Burst signal is looped through each of the routers
which are located together and a 75 Ω terminator is connected to the last BNC socket. An individual Black Burst
signal should be wired to routers which are more than a few meters apart.

If the reference signal is absent, the NK router will generate a free-running switching pulse over 40ms. The status of
the switching reference may be monitored on the router’s Device Properties page via the NK-IPS, one of three
conditions may be reported via the NK-IPS: Local, PAL reference present or NTSC reference present.

Connecting a Video Reference to NK Routers

When using a video reference with any of the NK router components, users must remember to terminate the last
video reference that is not looped with a 75 Ω BNC terminator.

When only video referencing one router, the other BNC connector of the video reference loop needs to be

terminated, as in Figure 5.2.
