About this Guide
The VN-Matrix 250 (VNM 250) series consists of the VNE 250 encoder and the VND 250
decoder. This guide contains installation, configuration, and operating information for both
the encoder and the decoder.
In this guide:
•
The terms "VNM 250" or "VNM" can refer to either the VND 250 or VNE 250.
•
The term "encoder" refers specifically to the VNE 250 encoder.
•
The term "decoder" refers specifically to the VND 250 decoder.
•
The term "stream" refers to multimedia that is constantly received by (and normally
presented to) an end-user while being delivered by a VN-Matrix encoding device.
About the VNM 250
The VNE 250 distributes video, audio, and data input across an IP network to one or more
VND 250 decoders. Transport across the network must be coordinated by a control device.
For a small system (ten devices or fewer connected to the network) the controller can be
either a VNM 250 encoder or decoder. For larger systems, a VNM Enterprise Controller is
required.
The VNE 250 encodes video, audio, and data inputs into PURE3 data streams for transport
across a local area or wide area network. Elsewhere on the network, one or more VND 250
units decode the stream.
VNE 250 inputs can include:
•
Analog (VGA) video
•
Digital (HDMI) video
•
Analog audio
•
Digital audio that is contained in an HDMI signal
•
Serial (RS-232) and UDP data
•
USB connections for remote mouse and keyboard
The individual video, audio, and data streams are synchronized and treated as a single
logical stream.
