5. System Modes and Connections
The VT-IPSD102H system operates in one of two modes: Encoder or Decoder. The VT-IPSD102H
system can be connected in either a ‘1-to-1’ fashion, where one encoder is connected to one decoder,
or a ‘1-to-many’ fashion, where one encoder is connected to many decoders.
The following chart shows possible combinations of video, audio and serial data transmission.

Therefore, the system modes are defined by the video communication and all system modes are
capable of bi-directional transmission of audio or serial data.
 Topology
Generally, the encoder and the decoder are connected in a 1-to-1 mode. To support specific situations,
1-to-many connection is also supported.
 1:1 Connection (Unidirection)
The most commonly used configuration is the 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 analog monitor. Audio and serial data are transferred in either direction.
