1.4 System Connections
Video Encoder operates as one mode;
Encoder.
Video Encoder Systems can be
connected in either
1-to-1
where one encoder is connected to one decoder or
1-to-
multiple
where one encoder connected to many decoders.
The following chart shows status of video, audio and serial data on each mode:

The system mode is defined by the video communication and this system mode is
capable of single directional transmission of audio and/or bi-directional serial data.
Topology
Generally, the Encoder and Decoder are connected in 1-to-1 mode. To support this
specific situation, 1-to-multiple connection is also supported.
1:1 Connection (Unidirectional Transmission)
The most commonly used configuration is 1-to-1 connection. An Encoder is installed
at a site where video images can be transmitted and a Decoder is installed at a center
location to receive and view the video images on monitors. Audio and Serial data are
transferred in either direction. An Encoder and Decoder can be connected by setting
the Encoder’s Address for the Decoder’s Remote IP.
