Hardware Description & Installation Manual
Electrostatic Discharge (ESD) Protection
Electrostatic discharge occurs when electronic components are improperly
handled and can result in intermittent failure or complete damage adversely
affecting an electrical circuit. When you remove and replace any card from a frame
always follow ESD-prevention procedures:
• Ensure that the frame is electrically connected to earth ground through the power cord
or any other means if available.
• Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the
grounding clip to an unpainted surface of the chassis frame to safely ground unwanted
ESD voltages. If no wrist strap is available, ground yourself by touching the unpainted
metal part of the chassis.
• For safety, periodically check the resistance value of the antistatic strap, which should
be between 1 and 10 megohms.
• When temporarily storing a card make sure it is placed in an ESD bag.
• Cards in an earth grounded metal frame or casing do not require any special ESD
protection.
Protection contre les décharges électrostatiques (DES)
Une décharge électrostatique peut se produire lorsque des composants
électroniques ne sont pas manipulés de manière adéquate, ce qui peut entraîner
des défaillances intermittentes ou endommager irrémédiablement un circuit
électrique. Au moment de remplacer une carte dans un châssis, prenez toujours les
mesures de protection antistatique appropriées :
• Assurez-vous que le châssis est relié électriquement à la terre par le cordon
d'alimentation ou tout autre moyen disponible.
• Portez un bracelet antistatique et assurez-vous qu'il est bien en contact avec la peau.
Connectez la pince de masse à une surface non peinte du châssis pour détourner à la
terre toute tension électrostatique indésirable. En l’absence de bracelet antistatique,
déchargez l’électricité statique de votre corps en touchant une surface métallique non
peinte du châssis.
• Pour plus de sécurité, vérifiez périodiquement la valeur de résistance du bracelet
antistatique. Elle doit se situer entre 1 et 10 mégohms.
• Si vous devez mettre une carte de côté, assurez-vous de la ranger dans un sac
protecteur antistatique.
• Les cartes qui sont reliées à un châssis ou boîtier métallique mis à la terre ne
nécessitent pas de protection antistatique spéciale.

Installation
The KMX-4911 is a flexible and scalable 4K- and IP-ready multiviewer for TV production
optimized for the space, power and weight considerations found in studios and outside
broadcast trucks. The KMX-4911 multiviewer modules are part of the GV Node IP
aggregation, processing, and edge routing platform, designed for live broadcast
production.
This section provides information about system requirements, the items shipped with your
KMX-4911 cards, and installation and maintenance procedures.
Introduction
KMX-4911cards are installed in a GV Node frame with a corresponding back panel that is
installed at the rear of the GV Node frame. Each KMX-4911 card can display up to nine
SMPTE ST 2022-6, 3Gbps, HD, or SD video inputs in up to nine video windows across one or
two high-resolution mosaic outputs. Combine up to four KMX-4911 cards, to configure a
dual- or quad-mosaic output system in the following sizes: 9 × 1, 9 × 2, 18 × 2, 18 × 4, 27 × 2,
27 × 4, 36 × 2 and 36 × 4. According to the number of KMX-4911 cards chosen for an
installation, a correspondingly sized rear panel is used to interconnect the cards.
KMX-4911 inputs are sourced from the GV Node’s fabric module, and thus from any SDI
input or IP input available to the GV Node. KMX-4911 mosaic outputs are made available to
the GV Node’s fabric module where they can be routed within the frame as any other signal
for IP distribution and these mosaic outputs are also optionally available on the rear panel
of the GV Node through one or two SFP output modules for connection to a display.
A single 4 RU GV Node frame can hold up to 16 KMX-4911 multiviewer cards, which can be
combined into anything from 16 separate 9 × 2 multiviewer systems, to 4 expanded 36 × 4
multiviewers. The KMX-4911 is ideal for production monitoring in trucks. It integrates
tightly with other Densité signal processing cards, routers and production switchers.
At the heart of every multiviewer system is the Kaleido-X software, which includes the
following client applications:
•XAdmin is a Web client that your system administrator will use to manage the
multiviewer system.
•XEdit is a client application used to create layouts for the monitor wall, and to configure
the multiviewer, from your PC or laptop.
•TheRouter Control Software Single Bus and Matrix View applications (also part of the
iRouter Router Control Software packaged with iControl Application Servers) can be
used to control your multiviewer’s logical sources and monitor wall destinations, via
the KX Router logical router, or to control other logical routers configured within your
multiviewer system.
•Signal Path Viewer opens as a standalone panel, updated in real time, showing
assignment information between router sources and multiviewer inputs. Signal Path

Unpacking
Unpacking
Make sure the following items have been shipped with your KMX-4911 order. If any of these
are missing, contact your distributor or Grass Valley (see Contact Us, on page 72).
Your KMX-4911 package includes the following:
• KMX-4911 cards (front and rear modules), as per order
• SFP modules, as per order, with adapter cables if required
• KMX-4911 Quick Start Guide
In addition to the above, you will need the following (not supplied):
•Upto4displays
•ClientPC
• Display cables (to connect your multiviewer to displays)
• At least one GV Node housing frame with available modular card slots
• Ethernet network connectivity
• Phillips #2 screwdriver to remove and install rear panels
How to Open and Close the Front Door
The front door of the GV Node frame is hinged on the right-hand side, and latched by a
captive thumbscrew on the left-hand side. There are no electrical connections to the door.
• Turn the thumbscrew counterclockwise until it releases, and pull the door open.
Close the front door as follows:
• Swing the door shut and turn the thumbscrew clockwise until the door is secured shut.
Installation of the KMX-4911 in the GV Node Frame
Installation overview
The KMX-4911 cards are installed in a GV Node frame along with the associated rear panel.
The rear panel must be installed in the GV Node frame before the card can be inserted into
the frame. If the KMX-4911 card is to directly support a video wall mosaic output, one or
two SFP module(s) must installed in the rear panel. See KMX-4911 Models and Related
Hardware, on page 11 for a summary of the hardware that can be installed. See also the GV
Node Quick Start Guide for information about how to install, power up, and configure a GV
Node frame.

Hardware Description & Installation Manual
Multiviewer with a KMX-4911-9x2-4SRP Rear Panel
The one KMX-4911 cards are installed in a GV Node Frame slot that the KMX-4911-9x2-4SRP
rear panel occupies.
A KMX-4911 Card shown Assembled with a KMX-4911-9x2-4SRP Rear Panel in a GV Node Frame
This KMX-4911 card accepts up to 9 video inputs from the GV Node frame’s fabric and can
source up to 2 mosaic returns to the GV Node frame’s fabric. It can also accept up to 64
discrete and 144 embedded audio channels from the GV Node frame’s fabric.
The slot a given KMX-4911 card is installed in determines the input range / mosaic return
range the card will use to communicate with the GV Node frame’s fabric. See Routing Inputs
and Mosaic Returns between the Multiviewer and the GV Node’s Fabric, on page 60.
