3. Product Overview

3.10. VINX Device Concept

The key feature of the VINX series is the AV signal transmission from
an Encoder to many Decoder devices. The number of the Encoder and
Decoder devices is 'limited' to 100 within a system. The video wall can
be expanded at a later time, e.g. building a wall with 12 Decoders and
add further 12 Decoders later. Another feature is the transmission of
RS-232, USB, and Infrared signals.
INFO:
The USB, Serial, and IR data transmission is working
independently from the video signal presence.
Unicast Mode (Point-to-Point Connection)
A Decoder is connected to an Encoder device.
Multicast Mode (Point-to-Multi point Connection)
Many Decoder devices are connected to the same Encoder.

The USB transmission is available only at one Encoder-Decoder
connection at the same time. The desired device can be activated by
the front panel button or via the built-in website.

3.11. Video Interface

The following sections describe the modes of the video transmissions.
When the necessary network settings are arranged, the followings
have to be set:
Video Stream ID Setting
DEFINITION:

that identifies a certain stream generated by an Encoder and
received by a Decoder.
The Video Stream ID creates the connection between an Encoder and
a Decoder. Set the Video stream ID to the same value in the desired
VINX devices:
▪ Use the DIP switch and set a value other than '0000', or
Set the DIP switch to '0000' and define the ID via the built-in web

3.11.1. One-to-one Video Transmission (Unicast Mode)

The Encoder and the Decoder devices are arranged in a LAN by
connecting them to an L2 or L3 switch. Setting the extenders to Unicast
mode it is possible to extend the video signal by an Encoder to a
dedicated Decoder.

INFO: The Encoder and the Decoder can be connected directly and
set to Unicast mode. In this case there is no need an L2/L3 switch
but there is no way to communicate with other VINX devices.
