Signal Compatibility — Video
The VN-Matrix 300 is supplied in one of three options, based on the type of digital video 
transport and video resolutions that it is intended to support.

Supported Video modes
The VN-Matrix 300 incorporates advanced image acquisition circuitry which can auto-detect 
the format of the connected signal without the need for any additional setup. Input sources 
are encoded and decoded at their native resolution and format. 
Signal Compatibility — Audio
The VN-Matrix 300 range of codecs support the transport of embedded audio data as 
described by the following SMPTE standards.
 
z
SMPTE 299M: 
24 bit digital audio
 
z
SMPTE 272M-A: 
20 bit digital audio
VNC 300 configured as an Encoder
The source signal is connected to the input BNC of the VNC 300. A reclocked loop through 
connection is provided for an external local monitor. In addition, a second loop through is 
available that includes an overlay function that may be used for identification purposes.
VNC 300 configured as a Decoder 
The decoded video signal is available on the output BNC. The loop through connector is not 
active. 
NOTE:  The input connector BNC on the decoder may be used to connect to a digital 
studio genlock signal.
Unit Setup and Configuration
Low level communications setup of the VNC 300 or VND 300 is achieved using a serial data 
link to the COM1 port. This interface provides for configuration of the network settings for 
each unit and is undertaken during commissioning. 
High level configuration is achieved via the network using the Integrated Web Management 
System.
There is no need for the VN-Matrix 300 units to be configured for a specific source type. The 
VNC 300 or VND 300 automatically identifies the source format of the signal connected to 
the encoder. The decoded image is presented in exactly the same format. 
Configuration of the system specific parameters is made via the Integrated Web 
Management provided by the controller.
