The NV9642 provides a tree-structured (or hierarchical) button layout. Configurers can define a
“tree” of buttons in such a way that each of the 30 LCD buttons can either (1) execute a function
or (2) select a subtree (i.e., present an entirely new set of functions at a different level in the tree).
The tree, with its subtrees, is not limited in size.

1. An equivalent NV9642V — a GUI that is called a “virtual panel”— is available. It emulates the NV9642.

Introduction

Panel Organization

We use the term “button page” or “page” to mean the set of 34 button functions at any partic­ular level in the tree.

Configurers will use ‘Navigate’ buttons to create new button pages (subtrees). During operation,
NV9642 users will press a ‘Navigate’ button to access a subtree. However, ‘Navigate’ buttons are
typically not labeled “Navigate”; they would be labeled according to the specific function they
perform in your system.

The panel can also display predefined button pages. For instance, a “category” button, when
pressed, will display one or more pages of sources or destinations through which the operator
may browse. A “menu” button presents a page of menu options.

Panel Organization

Function Buttons

The NV9642 has two rows of 17 LCD buttons — a total of 34 LCD buttons. Each has 3 lines of text
(up to 8 characters per line). The buttons can display one of seven colors dynamically: nominally
red, green, blue, purple, amber, yellow, or grey. An eighth color exists
is off.
If the button text occurs on only one or two lines, the button displays larger text, centered on
the button.

During configuration, you can assign any of the 7 colors to a button.

Each LCD button has four levels of brightness: off, low, medium, and high, and supports three
operational levels: high tally, low tally, and off. High tally can be either medium or high bright­ness and low tally can be either low or medium brightness. High tally is always constrained to be
brighter than low tally. See LCD Buttons

Although you can see a list of the pages in the tree during configuration, the structure of the
tree is not evident on the panel itself. The panel operator must commit the tree structure to
memory to be able to use the panel. It is up to the person configuring the panel to design a
usable tree structure.

Some buttons functions are assigned by the system depending on the context. For example. if a
button page is to represent all sources in a category, and that list changes, the button subtree
adjusts in size dynamically. The panel software adds a “forward” button and a “back” button if
there are more sources than buttons. Pressing the ‘Forward’ button takes you to the next page
of sources. Pressing the ‘Back’ button takes you to the previous page of sources.

Some button states depend on context. Many buttons remain unlit when their functions are
disabled. For example, ‘Page Up’ and ‘Page Down’ buttons remain unlit until there is an opportu­nity to scroll selection buttons. By default, an XY/MD button turns green for X-Y mode and
amber for multi-destination mode. ‘Save Preset’ goes low tally when you press ‘Clear Preset’.

The LCD buttons display a menu if the operator presses a menu button. When the operator
make a menu selection, viewable data are displayed on the LCD buttons. In some cases, the
operator can enter data (such as panel ID or LCD brightness) using buttons that allow data entry.

Configurers can define ‘Selection’ buttons that select a level during a breakaway setup. (Config­urers must do so if the operator is to make such selections.)

Scrolling is necessary when a list of items
of buttons available for the items. The panel adds ‘Forward’ and ‘Back’ buttons as necessary.

User’s Guide

Panels that use multi-destination mode will probably require ‘Page Up’ and ‘Page Down’
buttons.

Alphanumeric Display

The 4×22 alphanumeric display provides real-time feedback for the operators as they press
buttons to execute takes and other operations. The panel functions in two modes: X-Y or multi­destination and the display changes according to the mode:

In either case, the display has 4 rows. Operators might need to scroll the display to see addi­tional information. (The up and down buttons, right next to the display, are for scrolling the
display.)

Display Fields

The display has 2 columns:

• Level/Dest.

In X-Y mode, this column identifies the levels of the currently selected destination. That des­tination is identified in the information column. In the illustration above, ‘VTR--1’ was
selected. Operators might need to scroll to see or select a level.

In MD mode, the ‘Level/Dest’ column presents all the MD destinations defined in the
NV9642 configuration. (Actual destinations are defined in the NV9000 configuration.) Opera­tors might need to scroll to see or select a destination.

• Status.

The status column indicates what source was routed to a destination.

In X-Y mode, the status column represents the levels of a source or the levels of multiple
sources under breakaway. These are called the current source(s). The presence of ‘--------’ in
the status or preset columns means that that particular level is not defined for the destina­tion. Therefore, no source selection for that level is possible. The illustration above shows
that levels HD and ‘TimeCode’ are not defined for VTR 1.

5

Introduction

Panel Organization

In MD mode, the status column represents the sources routed to each of the destinations in
the ‘Level/Dest’ column. Again, these are the current sources.

In X-Y mode, the display uses its top row to show the selected destination. Therefore, in X-Y
mode, the display scrolls 3 lines at a time.

In multi-destination (MD) mode, the display uses all 4 lines to show MD destinations. In MD
mode, the display scrolls 4 lines at a time.

The display fields can show either aliases or system mnemonics for devices depending on (1) the
state of the ‘Name Set Toggle’ button (if the panel has one), (2) the default name set (3) the exist­ence of name sets in the NV9000 configuration. (An alias is a name defined in a name set.)

Flags

The display also shows flags of different kinds next to the sources and destinations.

Selection Marks

At the far right of the display are marks (3 small bars) that turn on to indicate selections.

In X-Y mode, the marks turn on to indicate that a level is selected and are not visible otherwise.
(The operator makes level selections in the button array.)

In MD mode, a mark appears to the right of the currently selected destination (and of all the
currently selection destinations in hold mode).

Other Signs

A plus sign (+) indicates that additional information is available. There is an ‘Info’ button that
operators may press to view the additional information.

In MD mode, an asterisk (*) directly after a source indicates a breakaway on that destination.

An ‘L’ indicates that a device has been locked. A ‘P’ indicates that a device has been protected.
NV9642 operators may lock, protect or release destinations. It is important for operators to
know that other operators may lock, protect, or release sources and destinations.

Tally Interface

At the rear of the panel is a DB25 connector that provides 8 tally inputs and 4 tally outputs. (The
outputs are solid state relay outputs.) Both inputs and outputs are optically isolated.

During configuration, you can construct Boolean logic that switches the outputs on. The terms
of the logic expressions are states of the source and destination devices, etc., controlled by the
NV9000 control system.

During configuration, you can prescribe NV9642 behavior that depends on the tally inputs.

What you connect to the tally interface is, of course, up to you. Grass Valley provides a breakout
cable (WC0053) for the tally connector as a purchase option.

The NV9000-SE Utilities on-line help documentation calls the tally interface a GPIO interface. On
the rear of the panel, it is labelled a “GPI interface.”

See Chapter 6, GPIO

, on page 69, for complete detail.

6

Modes of Operation

The panel operates in either X-Y mode or multi-destination (MD) mode. A single button (XY/MD)
can toggle between the modes. A third mode
“button-per-source” mode

The primary modes of operation are:

• X-Y mode — individual control of all router levels. Choose a destination, optionally choose

desired breakaway levels, choose a source, and press ‘Take’ to complete a desired route.

• Multi-destination mode — lets you control multiple destinations. The LCD buttons display

destinations and sources. You can scroll through destination lists using the ‘Page Up’ and
‘Page Down’ buttons. Select a destination using selection buttons, choose a source, and
repeat for all desired routes. Then press ‘Take’. Takes are “all level,” and breakaways cannot be
performed.

 The alphanumeric display scrolls independently of the selection buttons. Use the fixed

up/down buttons to scroll the display.

 The ‘Hold’ button allows you to select many MD destinations at once.

• Single-destination mode.

Single-destination” mode is not a distinct mode, but we mention it because it is a mode on
some other panels and can be simulated on the NV9642. It can be combined with the other
two modes. You can create many different forms of “single-destination” mode. This mode
may in fact have more than a single destination.

To understand single-destination mode, you must understand the different button types.
Please read the Configuration and Operation chapters and then see Single-Destination

Mode (page 38).

The secondary modes of panel operation are:

• Setup mode — where the NV9642 is freshly powered up, but disconnected from the net-

work. In this mode, you can preset the NV9642’s panel ID and perform a few diagnostic tasks.

• Salvo mode — pressing a Salvo button (and then the ‘Take’ button) executes a salvo. (The

duration of a salvo is indeterminate.)

• Menu mode — pressing a Menu button places the NV9642 in “menu” mode. In menu mode,

the LCD button array becomes a menu that changes as needed during menu operation.

Other modes of operation are:

• Hold mode — when you press the ‘Hold’ button, hold mode becomes active and when you

press it again, hold mode becomes inactive. See Hold

• Save preset mode — when you press the ‘Save Preset’ button, ‘Save Preset’ mode becomes

active and when you press it again, ‘Save Preset’ mode becomes inactive. See Save Preset
page 62.

Installation

Follow these steps to install a NV9642 control panel:

1 Mount, and secure, the panel in the rack.

The NV9642 is designed to mount in a 19” rack. Rack-mounting is not a requirement.

Place the panel in position in your rack. Attach the panel to the rack frame, using screws
appropriate for your rack. The panel’s mounting slots are spaced 1.75” (44.5mm) vertically
and allow approximately 1/8” (3mm) of movement horizontally.

2 We assume that you have an Ethernet switch connected to the “Panel and Router Network”

port of your system controller. Connect an Ethernet cable from that switch to the RJ-45 port
at the rear of the NV9642.

3 Connect one or both power supplies. First connect the 4-pin connector to PS1 or PS2 on the

rear of the router. The connectors are keyed and snap into place. There is only one way they
fit. Do not force them. Then connect the power supply to AC power.

A second power connection is for redundancy only (protection against failure) and is not a
requirement for operation.

Refer to Power Specifications

Power Cord Retention

on page 75 for details on the PS0001 power supply. See also

on page 82.

4 Connect tally (GPIO) input devices and output devices at the DB25 GPI connector.

You can use the optional WC0053 breakout cable to make these connections.

See Chapter 6, GPIO

, on page 69 for detail regarding the tally interface.

Installing Software and Documentation

This document is available through the Grass Valley web site.

You must use NV9000-SE Utilities to configure the NV9642 control panel. Contact Grass Valley if
you need to obtain the latest version of this NV9000 configuration software.

You may use the Panel IP Configuration Utility if you want to your NV9642 to have a static IP
address or to use DHCP. The panel, as it comes from the factory, defaults to DHCP.

TEST
MODE

Before your system controller can communicate with an NV9642, you must give the NV9642 a
panel ID. Follow these steps for each NV9642 you are installing:

1 Power up the NV9642. Do not connect its Ethernet cable. (Disconnect it if it is connected.)

2 Press the ‘Menu’ button to enter the menu. The menu button now displays ‘Exit’. At any time

3 Find and press ‘Enter Panel ID’ among the panel buttons on the left.

NV9642

User’s Guide

After a few seconds, the alphanumeric display will show ‘Acquire IP Address’ at the top and
show the panel’s current panel ID. The right-most button in the top row illuminates and
reads ‘Menu’:

during this process, you can press the exit button to “back out of” the process. You might
have to press it more than once.

Testing

The ‘Panel ID’ button shows the current panel ID

— in this example, it is 4200.

4 After you press ‘Enter Panel ID’, the panel illuminates 10 “digit” buttons on the top row of

buttons. Press the digits of your intended panel ID in order

— up to 8 digits. Then press the

‘Save’ button (on the right) to save the ID, press the ‘Clear’ button to discard the ID, or press
‘Exit’ to return to the menu.

5 You may use any other menu function at this time. When you are finished, press the exit but-

ton (which reappears) to leave the menu.

6 After you designate the panel ID, reconnect the Ethernet cable. The system controller will

detect your panel in a few seconds. (All panel IDs must be unique.)
You can now prepare an NV9642 configuration in NV9000-SE Utilities and upload the configura­tion to the NV9642. You need the panel ID to create a NV9642 configuration. When you upload
the configuration, the panel ID you entered in NV9000-SE Utilities designates the actual panel to
which the upload will occur. If no actual panel has that ID, the upload cannot occur.

As shown previously, in step 3, a panel test function is available when the NV9642 is discon­nected from the system controller. Run the test to determine the health of your NV9642. See

Setup Mode

on page 65 for detail. Press the ‘Software Versions’ button to review the versions of

installed software and firmware.

These are points to consider after you install your NV9642 control panel(s):

1 Do the buttons illuminate? When an NV9642 powers up, its two leftmost LCD buttons are

supposed to turn green. Does it pass the panel test mentioned above?

2 When the NV9642 powers up and it is connected to the system controller, it should initialize

completely. (That takes a few seconds.) The NV9000 system should load whatever configura-

11

Installation

Testing

tion exists for that panel and the buttons appropriate for that configuration should light in

the colors appropriate for the top-level button page of that configuration.

If you continue to see “No Server,” “Acquiring IP Address,” or “Locating Network” on button 2,

you have a problem. Reboot everything and try again.

 The NV9642, by default, acquires its IP address through DHCP on the system controller’s

panel/router network. You can use the Panel IP Configuration Utility to force the panel to
have a static IP address.

If (in setup mode) you do not see your designated panel ID on the display, you have either

not initialized the panel or no configuration has been created for your panel in NV9000-SE

Utilities.

3 Is the system controller actually running? With the typical noise levels in a facility, it can

sometimes be difficult to tell. Use the ‘System’ pages of NV9000-SE Utilities to make the

determination.

4 Is NV9000-SE Utilities installed and operating? If so, can you upload a configuration to the

specified panel?

5 Does the configuration actually work? Is it useful? Can the operator perform takes and per-

form other operations?
The design of an NV9642 “operator interface” is non-trivial. You might want to consider how well
your operator interface works in addition to the basic question of whether it works.

Summary

The NV9642 has a “multi-page” user interface. Each of its 34 buttons (illuminated in various
colors and having 3 lines of text) can either (1) execute a function or (2) select another button
page (i.e., present an entirely new set of functions). The set of button pages is not limited in size.
Panel operators navigate to different button pages to perform different tasks.

We say that the user interface is tree-structured (or hierarchical) although it is not always a “tree”
in the strictest sense. (You can construct a tree-like graph of the button pages.)

The NV9642, in addition, has an 4×22 alphanumeric display that presents the status of opera­tions as they occur. The NV9642 panel has up and down buttons next to the display with which
the operator can scroll the display.

At the rear of the panel, a DB25 connector supports 8 tally inputs and 4 tally outputs.

NV9000-SE Utilities is the software with which to configure the NV9642. Figure 4-1, following,
shows the default NV9642 panel configuration page from NV9000-SE Utilities.

Adding a Panel to an NV9000 Configuration

You must create configurations for the NV9642 using NV9000-SE Utilities. We assume that you
are familiar enough with NV9000-SE Utilities that you can understand the following material. It
is not difficult material, but some of the concepts might not be familiar to everyone.

It takes only a few seconds to add a new panel configuration.

13

Configuration

Adding a Panel to an NV9000 Configuration

After launching NV9000-SE Utilities, choose ‘Control Panels’ from the Configuration pane in the
navigation area. The ‘Control Panels’ configuration page appears:

Click ‘Add Control Panel’ at the bottom of the configuration page. The ‘Add Control Panel’ page
appears:

14

Choose “NV9642” from the ‘Type’ field. In the ID field, enter the panel ID you assigned to the
panel while it was in setup mode. Give a name to the panel in the name field and select a user.

When you are creating a panel configuration you have 3 options. These options are presented in
the ‘Configuration Options’ area:

1 Make a copy of an existing configuration file, giving it a new file name.

2 Use an existing configuration file. (This allows several panels to share a single configuration.)

3 Create an entirely new configuration file.

In the first and third cases, you will create a new configuration file whose name you designate.
The file extension for an NV9642 configuration file is

.642. Click ‘Next’ or ‘Finish’ to proceed.

Regions of the Configuration Page

Above the ‘Revert to Saved’ and ‘Save’ buttons (always present) there are 5 main regions:

• A graphic representation of the NV9642 panel.

On the right are 34 function button images. Click on a button to assign a function to it. In

some cases, you can click or double-click certain buttons to execute the button function.

Double-clicking a ‘Navigate’ button, for instance, causes the button’s “subpage” to appear.

 The image of the alphanumeric display is not used. The images of the fixed up/down

buttons, just to the right of the image of the display, are not used.

Double-clicking a ‘Page Up’ or ‘Page Down’ button (not the same as a fixed up or down but-

ton) allows you to scroll through multi-destination pages that are represented in the image

of the alphanumeric page.

Buttons can be illuminated in several colors: green, amber, yellow, red, blue, purple, and

grey. There are 3 levels of illumination: high tally (bright), low tally (muted) and off. Unde-

fined buttons are turned off (dark) on the actual panel and are gray in the configuration

page.

 Buttons disabled during operation have text, but are dark on the control panel. Unde-

fined buttons are dark and have no text.

• Button definitions.

In this section, configurers make button assignments, using its pull-down menus and text

fields. The menus and fields vary with the button type.

See Button Definitions

• Button page table.

This section

— the region below the button definition section — displays a list of the individ-

ual pages of the tree structure. The button page at the top of the list (or root of the tree) is

called “Default.”

During operation, category buttons can display device subpages when pressed. Those sub-

pages are not definable in NV9000-SE Utilities. The button page list does not display the

device subpages accessed through category buttons. Category buttons can also display suf-

fix pages when pressed. Suffix pages are included in the button page table.

• GPIO definitions.

In this section, configurers may define GPIO logic. The control panel has a rear connector

that provides 4 relay outputs and 8 optically isolated inputs. See GPIO

information. (Note that the graphical buttons represent connector terminals and not actual

buttons.)

• Panel options.

In this section, configurers may specify the behavioral characteristics of the panel.

• Display options.

In this section, configurers may partially specify the behavior of the display when the panel

is in X-Y mode.

In X-Y mode, the display shows 3 lines of level information. (The display also scrolls by 3 lines

at a time.) The display options let you specify explicitly what levels appear on those 3 lines.

The specification applies, however, only to the first page of the level display.

Configuration

NV9642 Panel Configuration Page

For example, if your NV9000 configuration has levels HD, SD, AES12, AES34, AES56, AES78,

timecode, and ‘Ctrl’ defined, and you specify that HD, AES12, AES34 are to appear on lines 1,

2, and 3, that will always happen. Then levels SD, AES56, and AES78 will appear on page 2,

and ‘timecode’ and ‘Ctrl’ will appear on page 3 as the operator scrolls.

During configuration, you may leave any of the fields in this section blank. If you leave all 3

fields blank, the display will present levels in their default order (according to their display

index, as defined in NV9000-SE Utilities).

If you leave only one or two fields blank, those display lines will appear blank, while the line

for which you specified a level will show that level.

Configuration Tasks

The person configuring an NV9642 panel will want to consider how best to use the hierarchical
nature of the button tree to support the devices and routers in the router control system at
hand. The task is non-trivial.

In support of that effort, the configurer will do the following:

• Select panel options.

• Assign functions to buttons.

• Create pages (subtrees) of buttons. (Do this using the Navigation button type).

• Define logic for some or all of the tally inputs and outputs.

A configuration should lead the operator through required tasks. It is possible to make naviga­tion through the tree structure of panel operations intuitive through the judicious use of color
and text on the LCD buttons.

The configurer must keep in mind that the operator generally cannot view the entire button
tree at a glance.

The configurer must also keep in mind that the operator must be able to reach any page in the
tree. In particular, the operator, having navigated down a subtree, must have some way to navi­gate back up the subtree. There are several ways to ensure this. Two ways are listed here:

• Place a “Back” button on each subpage. The “back” button causes the NV9642 to redisplay

the previous page.

• Place a “Navigate” button on each page, where the navigate button causes the NV9642 to

display a specific page.

 The operator can always return from system-generated pages (e.g., device lists) using the

‘back’ button.

The panel operator, in most cases, needs a ‘Take’ button and at least one selection button. In
addition to their basic function, selection buttons provide feedback about the preset source
device and level mapping. A ‘Clear Preset’ button is strongly recommended.

 We recommend that you place exactly 8 selection buttons on a page and that they reference

all display indexes.

Commitment Buttons

Two buttons at the bottom of the configuration page are self-explanatory and present on most
configuration pages:

• Revert to Saved. Press this button if you want to discard any recent changes you have made.

• Save. Press this button to commit all your recent changes.

Neither of these actions is reversible.

Panel Options

The panel options section, in the middle of the configuration page, has two parts: drop-down
menus and checkbox options. These are the drop-down menus:

User’s Guide

These are the options:

Default Mode X-Y Mode Starts the panel in XY mode after a reset. See Defaults on page 77.

Multi-Dest Mode Starts the panel in multi-destination mode after a reset.

Release Mode Normal Release This panel can release “locks” and “protects” set by the designated

user (at this panel or any other panel).

Force Release This panel can release locks and protects set by any user.

Preset Monitor None The preset source video is not sent to a monitor.

Status Monitor None The current source video is not sent to a monitor.

None After a reset, the panel displays no destination device. (This is not

recommended.)

‹device› The Panel uses the specified device as the destination after a reset.

(The ‘Default State’ button also returns the panel to this destina­tion.)

‹device› The preset source video for the selected destination appears on

the specified monitor (device).

‹device› The current source video for the selected destination appears on

the specified monitor (device).
