3. Product Overview
3.14. RS-232 Interface
Serial data transmission works between an Encoder and all the
connected Decoders which have the same Video Stream ID. This
transmission is independent of the current working mode (Unicast/
Multicast). To connect serial devices please use the cables supplied
with the extenders.
AAAENAIING!
The serial data is transmitted only if video is
transmitted between the affected devices.
Pass-through Mode
DEFINITION:
The Pass-through mode means fully transparent
bidirectional data transmission from an RS-232 port of a VINX
Extender to an RS-232 port of a VINX Decoder – and Vice versa.
All data received from the serial ports of the Decoders is transmitted
to the serial port of the Encoder and vice versa: the data received from
the serial port of the Encoder is transmitted to the serial ports of all
connected Decoders.

RS-232 Data Transmission (Pass-through mode)
Please note that transmitting data between two Decoders is not
possible; see the above figure: sending serial data from the Touch
Control to the Projector is not possible.

AAAENAIING! The data transmission works only if the serial port
parameters are set to the same values in all devices: serial data
sender/receiver and the VINX Encoder and Decoder devices.
Command Injection Mode

DEFINITION:
bidirectional converter. The mode allows data transmission between
a TCP/IP device and a serial device.
When a device is connected to the network (e.g. TCP/IP connection
from a computer) and a serial device is connected to the RS-232 port
of a VINX device they can communicate with each other.
