Controlling Features
The control interfaces of MODEX devices can be used to install both
the transmitter and the receiver at various points in a complex A/V
system. This section presents the various type of control interfaces
and their working modes.
ATTENTION!
The presence of the following interfaces and features
depends on the installed interface card in your MODEX device.
3.13.1.
Serial Interface
Technical Background
In crosspoint view every serial port appears as an input and an output.
It means that Tx data channel of the port is an input and Rx data
channel is an output – within one port.
All serial input data are transmitted to the remote device all the time.
Thus, the link does not appear as an output as it appears in video or in
audio crosspoint. The input port with a link icon symbolizes the input
of the remote side. The serial source switched to the local output can
be selected on the local device.
The number of the available ports in a unit is determined as follows:
▪
Number of inputs = Number of the ports [local unit] + Number of
the ports [remote unit]
▪
Number of outputs = Number of the ports [local unit]
If an input is switched to an output, and both the input and the output
belongs to the same serial port connector, the result is an internal
loopback. This way the serial link can be tested between the source
device and the MODEX.

3.13.2.
Infrared Interface
Technical Background
All infrared input data are transmitted to the remote device all the time.
Thus, the link does not appear as an output as it appears in the video
or in the audio crosspoint. The input port with a link icon symbolizes
the input of the remote side.
The number of the available ports in a unit is determined as follows:
▪
Number of inputs = Number of inputs [local unit] + Number of
inputs [remote unit]
▪
Number of outputs = Number of outputs [local unit]
ATTENTION!
The selection should be done on the local device
whose infra source have to be output on a local infra port.

Command Injection - Signal Path
Signal transmission between local Tx/Rx pins and local IP port
Loopback - Signal Path
Signal transmission between local Tx and Rx pins
Extended Data - Signal Path
Signal transmission between local and remote devices
ATTENTION!
To have a bidirectional connection the link must be
enabled in both extenders.
INFO: The working method is similar when more RS-232 ports are
assembled in the MODEX, e.g. 2 pieces of MODEX-IF-2xRS232
interface modules (with 2 x 2 pcs. RS-232 ports). But in that case
the number of the signal path is multiplied.
