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.
Précautions pour les écrans LCD et TFT
Regarder l’écran pendant une trop longue période de temps peut nuire à votre
vision. Prenez une pause de 10 minutes, après 30 minutes d’utilisation.
Si l'écran LCD ou TFT est brisé, manipulez les fragments de verre avec précaution au
moment de vous en débarrasser. veillez à ce que le cristal liquide n'entre pas en contact
avec la peau ou la bouche. En cas de contact avec la peau ou les vêtements, laver

iv
immédiatement à l'eau savonneuse. Ne jamais ingérer le liquide. La toxicité est
extrêmement faible, mais la prudence demeure de mise en tout temps.

The NV8900 product family includes 6 MADI interfaces:
•MADI to AES, unbalanced •AES to MADI, unbalanced
•MADI to AES, balanced •AES to MADI, balanced
•MADI to analog audio •Analog audio to MADI
By AES we mean AES-3 and by MADI we mean “multi-channel audio digital interface,”
governed by standard AES10-2003.
The two analog audio interfaces are quite different from the AES interfaces and are
discussed under Analog Audio Interfaces on page 5.
AES Interfaces
The two MADI-to-AES interfaces are demultiplexers that have one MADI input and 32 AES
outputs. The unbalanced outputs use 75WBNCs; the balanced outputs use 110W shielded
twisted pairs on DB25 connectors.
The two AES-to-MADI interfaces are multiplexers that have 32 AES inputs and one MADI
output. The unbalanced inputs use 75WBNCs; the balanced inputs use 110 W shielded
twisted pairs on DB25 connectors.
The MADI inputs and outputs are 75WBNCs.
The AES-to-MADI interfaces accept up to 64 audio channels. The MADI-to-AES interfaces
produce 64 audio channels. The individual MADI channels are paired on the AES inputs or
outputs. AES connector 1 corresponds to MADI channels 0 and 1; AES connector 2
corresponds to MADI channels 2 and 3, and so on. AES connector 32 corresponds to MADI
channels 62 and 63.
The AES interfaces are 1RU and about 2″in depth. The following photographs are
representative:
This is a front view of the AES (balanced) to MADI interface. The other AES units resemble
this one, where the difference between the models is the legend.

NV8900
This is a rear view of the AES (balanced) to MADI interface:
It has 4 DB25 connectors supporting the AES inputs. The MADI to AES (balanced) interface
is similar, except for the legend.
This is a rear view of the AES (coax) to MADI interface:
Here, there are 32 BNC connectors supporting the AES inputs. Here, too, the MADI to AES
(coax) interface is similar, except for the legend.
Functions
The AES models convert discrete AES signal pairs to MADI format or vice versa.
The MADI-to-AES interfaces interpret the incoming framing data and preserve VUCP data.
The AES-to-MADI interfaces preserve VUCP and also generate the framing data (in the first 4
bits of each MADI subframe).
Each interface has a video reference input (loop-through). Each interface has a serial port
(DE9) that is reserved for future use. Each interface has an Ethernet port (RJ-45) for a
connection to MRC (the Miranda Router Configurator).
Each interface has two power connectors (for PS0001 power supply) and a grounding
terminal.
Rates
The MADI interfaces send and receive AES at exactly 48.0 kHz (samples per second).
Configuration
You can use MRC (Miranda Router Configurator) to change an NV8900’s IP address and also
to upload firmware.
The NV8900 has a 16-position rotary switch (Frame ID) on the front. This switch exists so
that different NV8900 frames can be distinguished (by MRC) on a network. The switch is not
required for operation.
Operation
The NV8900 AES interfaces function on their own and do not require an operator.
It is sufficient to rack-mount the devices and connect cables to your inputs and outputs.
