INTRODUCTION 3
1. INTRODUCTION
WATCHPAX 40 is a dedicated media server with four DisplayPort video outputs and a built-in Dataton
WATCHOUT license. The server is designed solely with WATCHOUT shows in mind and offers built-in
EDID, as well as smart restore/reset.
WATCHPAX 40 is a locked-down unit, precongured for playback of WATCHOUT shows only.
Multiple units can be installed together in a rig or combined with Dataton’s other media servers.
WATCHPAX 40 weighs just under 3 kg and is a handy lettersize format making it easy to transport.
Other practical details include rubber bumpers, Kensington security slot and a strap handle for
carrying.
Two units may also be mounted together and then installed in a 19-inch rack.
WHAT’S WATCHOUT?
Dataton WATCHOUT is the leading multi-display production and playback software. Use
WATCHOUT to orchestrate images, video, lighting, 3D and interactivity into a single impressive show.
The essential components of a WATCHOUT show are the software, media servers (such as
WATCHPAX 40) and display devices (projectors, LED displays, etc), running on a standard network.
In an operational setup, a WATCHOUT license key is required for the production computer running
the show and each media server. All Dataton-branded media servers, including the WATCHPAX 40,
have the license key built in.
WATCHOUT shows can be presented with multiple projectors for large, seamless images or used with
monitors, LED walls or other creative screen arrangements. WATCHOUT also has a strong set of pro-
jection and pixel-mapping features for applying content to complex three-dimensional objects.

INTRODUCTION 4
SYSTEM OVERVIEW
WATCHPAX 40 is used as part of a WATCHOUT multi-display system.
Production
computer
Network switch
WATCHPAX 40
(media server)
A small WATCHOUT system with WATCHPAX 40
In the schematic above, there is a laptop (production computer) running WATCHOUT software and
equipped with a WATCHOUT license key. This connects to a network switch which, in turn, connects
to a Dataton WATCHPAX 40 media server. The WATCHPAX unit connects and manages the display
devices. In the example, these consist of four LED screens.
WATCHPAX 40 IN YOUR RIG
The WATCHPAX has four DisplayPort outputs. Used as is, it will manage four display devices in your
presentation. Splitters may also be used to increase the number of display devices managed. The
system is scalable – if you want to increase the number of display devices, add more media servers to
your rig.
All Dataton media servers have a built-in WATCHOUT license but you will need an additional license
key for your production computer. If you are not using a Dataton media server (WATCHPAX or
WATCHMAX) you will need a WATCHOUT license key for each media server/display computer.
DISPLAY DEVICES
In the illustration above, four LED screens are used as the display devices. However, WATCHOUT can
be used with virtually any display device that can be connected to a computer (such as projectors,
LCD panels, LED walls etc).
START UP SCREEN
This is shown on all display devices connected to the WATCHPAX 40 at start-up, or if WATCHOUT has
been re-launched. There are three lines of information:
First line: Computer and cluster name (if this has been set in the WATCHOUT Production software
Network window – please see the “Network Window” section in Chapter 3: Windows, “Dataton
WATCHOUT User’s Guide” for more information), IP address for the media server.

MEDIA SERVER OPERATING SYSTEM
The operating system in WATCHPAX 40 has been optimized and licensed for this specic media
server conguration.
Do not install or attempt to install any software on the locked-down media server (such as drivers,
software updates, security updates, virus protection, etc). Doing so will automatically void the unit’s
warranty.
For security reasons, media servers should always be installed and operate on a separate network,
without access to other networks.

INSTALLATION AND OPERATION 7

VENTILATION
Airow is critical for the correct operation of WATCHPAX 40.
There are four built-in fans which maintain airow and cooling during operation. Air ows from the
front of the unit to the rear. Keep therefore both front and rear panels clear of obstruction at all times.
In an installation, there should be a minimum of 200 mm clear space at front and 200 mm at back of
the unit.
INSTALLATION
GENERAL
• This equipment is for professional use for installation at locations where only adults are normally
present. Check the “Safety First” list before use.
• The WATCHOUT 40 must be connected to a properly grounded wall socket (a socket-outlet with
protective earth connection in the building).
• The serial number is located on the base of the unit.
IMPORTANT: Only use the power cord supplied with the WATCHPAX 40 unit, otherwise Dataton AB
cannot guarantee full functionality.
Air inlet: do not block.
Keep a minimum 200 mm clear space at front of unit
Air outlet: do not block.
Keep a minimum 200 mm clear space at rear of unit

INSTALLATION AND OPERATION 9
STANDALONE INSTALLATION
Place the unit at on its base. The base is the side of the unit showing the serial number and Dataton
logo.
INSTALLATION IN 19-INCH RACK
The WATCHPAX 40 unit may be mounted in a 19-inch rack by using the rack kit, “Rack Mounting Kit”
(product number 9784) which is available separately. Using the kit, two WATCHPAX 40 units are
joined and can then be inserted into a 19-inch rack.
IMPORTANT: The two WATCHPAX 40 units are attached with brackets at the front of the rack. The
rack must therefore be equipped with a shelf at the back to support the units.
• Using a hex key, remove the rubber bumpers on both units and retain the screws. Save the bumpers
in case you wish to re-mount them at a later date.
• Place the two WATCHPAX units side-by-side and join them in the middle with the connection discs.
Using the screws from the bumpers, rst mount two discs on the top of the units. Carefully turn the
unit over and mount the remaining two discs along the center line on the underside of the units.
• IMPORTANT: Always mount all four discs to ensure the units are safely joined together.
• Attach the two rack brackets (or ears) on the front corners of the joined units. These can be tted
facing forward or backward, depending on the airow, and cabling.

POWER ON
There is no on/off switch on a WATCHPAX 40. The unit is turned on by inserting the power cord.
FIRST POWER ON
The rst time you power up a WATCHPAX 40 (after delivery or after a reset) the system will nalize
installation and reboot several times. This procedure will typically take about 5 minutes to complete.
IMPORTANT: Do not interrupt this procedure.
POWER OFF
Powering down should be initiated from within WATCHOUT production software.
When the power-off sequence is complete, the fans will turn off, and the power cord may be removed.
There are three ways to power off from WATCHOUT, as described in the “Manage Display Com-
puter” section in Chapter 3: Windows, in the “Dataton WATCHOUT User’s Guide.”

INSTALLATION AND OPERATION 10
• Use Manage Display Computer > Power Down found in the Stage main menu.
• Use the Manage Display Computer context menu when a display is selected on the Stage.
• Use the Remote Access to initiate shutdown directly from the media server.
NOTE: If you need to perform a forced shutdown, unplug the power cord to turn off the unit.
RESET WATCHPAX 40
There are occasions when you may want to reset a WATCHPAX 40, for example, if the unit has been
corrupted, or if it’s a rental unit and user-specic info has to be removed between rentals.
There are two levels of reset:
• Reset and keep user data. This resets the operating system, display, GPU and capture settings but
retains user data, such as shows and media.
• Reset to factory settings. The takes the unit all the way back to the original factory settings‚ you lose
all user data.
IMPORTANT: A reset, regardless of level, is an advanced measure. Make sure you are fully aware of
what data you lose when you reset!
RESET AND KEEP USER DATA
This option resets the system partitions but keeps all user data such as:
• Shows
• Media
• WATCHOUT settings
• Startup script
- Network settings
- Timecode settings
Driver-related settings will be reset to default factory settings such as:
• Display settings
- Display mode
- EDID caching
RESET TO FACTORY SETTINGS
This resets all partitions to factory settings and all user data will be lost. This level of reset is suitable
when you want to remove all settings between projects.
RESET PROCEDURE
The reset menu is hidden by design in order to avoid accidental resets or misuse. To reset your
WATCHPAX 40 device, follow these 10 steps:
1. Power off the WATCHPAX 40.
2. Disconnect all USB devices.
3. Insert a keyboard into one of the two USB ports.
4. Connect at least one display device to a DisplayPort output.

INSTALLATION AND OPERATION 11
5. Power on the WATCHPAX 40.
6. During startup, you will see a ve-second countdown in the top left corner of the display. Press Esc
during this countdown.
NOTE: If you don’t see a counter, it means the display device is slow to lock to the output using
DisplayPort. Press Esc repeatedly after power-on to move to the menu below.
7. Select the desired reset option in the menu that appears, and press Enter.
8. IMPORTANT: There will be no conrmation: the reset process starts immediately, providing some
visual feedback.
9. The WATCHPAX 40 will restart several times in order to congure the operating system and
hardware.

INSTALLATION AND OPERATION 12
IMPORTANT: Do not power off the device during the conguration process!
10. WATCHOUT will start when the process is complete. The system image version will be appended
after the serial number (r14 in this example).

INSTALLATION AND OPERATION 13
DELETE FILES
To remove unused les from the WATCHPAX unit, open WATCHOUT on the production computer on
the network. Go to the Stage menu, as below:
Stage > Manage Display Computer > Delete Other Shows
This deletes les from online display computers for all shows, with the exception of the current (open)
show.
REBUILD SHOW CACHE
WATCHOUT usually manages the cached data associated with the current (open) show automatically.
This ensures that the les stored on your WATCHPAX 40 reect the latest version of the show.
If the les on the WATCHPAX 40 have been corrupted in some way, you may want to force the show
cache to rebuild.
Open WATCHOUT on the production computer on the network. Go to the Stage menu, as below:
Stage > Manage Display Computer > Re-build Show Cache
This removes and rebuilds all cached data associated with the current show.

QUICKSTART GUIDE 14
3. QUICKSTART GUIDE
THE BASICS
• Connect displays to the WATCHPAX 40 using the DisplayPort outputs and adapters.
• Connect the WATCHPAX 40 to the network using the Ethernet port.
• Power up the WATCHPAX 40 (see “Power On”).
• Start WATCHOUT software on the production computer which is on the same network. Make sure
you are using WATCHOUT version 6.4 or higher.
• The WATCHPAX and any WATCHOUT display computers on the local network will be listed in
Window > Network. Assign display and cluster names (if required) by double-clicking an item in the
list, see screenshot.
MANAGE NETWORK SETTINGS
WATCHPAX automatically retrieves an IP address via a DHCP server. If no DHCP server is available,
the WATCHPAX will get a self-assigned IP address in the range 169.254.x.y
If you are using a control system, you may want to use a xed IP address for WATCHPAX. Still in
WATCHOUT, assign a xed IP through the WATCHOUT protocol command “setIP” in the Startup Script
as shown below:
authenticate 2
setIP 192.168.0.32
Make sure you choose an IP address in the correct subnet range. To remove the xed IP number, use
the same command but with an empty string parameter, as below:
authenticate 2
setIP
WATCHPAX 40 on the network

QUICKSTART GUIDE 15
The WATCHPAX 40 may also be addressed by name and/or cluster. Please see the “Network Win-
dow” section in Chapter 3: Windows, “WATCHOUT User’s Guide” for more information about this
feature.
SET NATIVE RESOLUTION
Double-click the display in the Stage window and set the native resolution of your screen or projector,
see screenshot.
AUTO START
A WATCHOUT production computer has to be connected when you compose or create your show.
Once you have composed your show, you can replace the production computer with an external
control system, or auto-start the WATCHPAX by using the built-in Startup Script.
NOTE: Use Edit Startup Script in WATCHOUT to dene initial WATCHPAX settings. This lets you load
shows and perform other WATCHOUT protocol commands. For more information, please see the
section on“Display Software,” Command Line Options, “WATCHOUT User’s Guide”.

EDID MANAGEMENT 16
4. EDID MANAGEMENT
Extended Display Identication Data (EDID) is a standardized data format for a display, such as a
projector, screen or monitor, to describe its performance capability to a video source (in this case,
WATCHPAX 40). The information exchanged in an EDID handshake includes the resolution, refresh
rates and timings available in the display.
This section is a walkthrough on how to manage EDID on a WATCHPAX 40 using NVIDIA’s control
panel. The following functionality is provided:
• Export EDID from a display to le.
• Load EDID from le in order to emulate EDID on one or multiple outputs. This makes it possible to
output a signal whether a display is connected or not.
• Unload the emulated EDID in order to switch to the EDID of a connected display device.
HINT: For xed installations it’s recommended to emulate EDID for a more robust operation. This
makes the WATCHPAX independent of the power state of the connected display device(s).
ACCESS EDID MANAGEMENT SETTINGS
To congure and setup EDID, access each media server locally. Do this either by a Remote Access
(from the WATCHOUT production computer) or connect a USB keyboard/mouse and screen to your
WATCHPAX 40.
Connecting by Remote Access will automatically bring up the WATCHOUT Display window
(WATCHPOINT). If you are using a local keyboard/mouse and screen, enter Ctrl-W to bring up this
window.
You’ll nd more on this in the “Dataton WATCHOUT User’s Guide” in the section on “Display Devices”
(Chapter 2: Installation) and “Remote Access” (Chapter 4: Commands).
Follow this procedure to access EDID management settings:
1. In the menu select File >GPU Settings.

EDID MANAGEMENT 17
2. Navigate to the Workstation >View System Topology (gure 2).
3. All outputs are listed within the Quadro P3000/P4000 section. Open the “Manage EDID” window
by clicking the EDID link (gure 3).
It’s possible to export EDID les to external USB devices or to store them locally on the W:\ drive. Files
stored on the system (C:\) will not be persistent.
EXPORT EDID
To export EDID from a display, select an active display and press the Export button.

EDID MANAGEMENT 18
LOAD EDID
To emulate an EDID on selected display(s) from le (gure 4):
1. Select the “Load” tab.
2. Check the outputs to override.
3. Press the “Load EDID” button.
UNLOAD EDID
To remove the EDID emulation on selected displays (gure 5):
1. Select the Unload tab.
2. Check the outputs to unload.
3. Press the Unload EDID button.
