NV8900
AES Interfaces
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.
