3. Product Overview
3.10.2. IR Interface
ATTENTION! The device has no built-in Infrared receiver and transmitter. For the complete usage attach
the supplied IR emitter unit to the IR OUT and the IR detector unit to the IR IN connectors.
Technical Background
ATTENTION! Only MMX4x2-HT200 model has TPS LAN port.
The Infrared signal transmission is similar to the serial data communication. The MMX4x2 series matrix
contains dedicated IR I/O connection and the MMX4x2-HT200 model can also transmit/receive IR signal via
the TPS interface. The signal is in pronto HEX format in both cases.

With the help of the device's IR recognizer functionality you can assign actions in Event manager. The second
option is the command injection mode (like at serial interface in the previous section) where you can send IR
commands over LAN. Command injection mode can be turned on and off by input/output ports.
INFO: All settings are available in the LDC software, see settings in the
INFO: The modulation of output IR signal can be turned off or on by LW3 command, see the
Disable Output Signal Modulation section.
Control by IR Signal - Example
Remote controller
The Concept
An IR detector is attached to the Infrared input port of the Matrix and IR signals are sent by the Remote
controller. A pair of active speakers is also connected to the analog audio output port of the Matrix.

The volume can be controlled via the Matrix by using the remote controller with the following way:
▪ Set an action in Event Manager that if the volume control buttons are pressed on the Remote controller,
increase or decrease the volume of the analog audio port of the Matrix. In this case you can control the
audio device via the Matrix remotely. See the details about the Event Manager settings in the
Manager section.
TIPS AND TRICKS: You can increase or decrease the levels of analog audio output ports in steps by LW3
protocol commands, see the details in the
3.10.3. USB Control Interface
The device can be controlled over front panel USB port (mini B-type connector). This interface only supports
LW3 protocol. The interface can be used to establish a connection to Lightware Device Controller software.
3.10.4. Ethernet Control Interface
The device can be controlled over front panel Ethernet port (standard RJ45 connector). This interface
supports both LW2 and LW3 protocols.
The interface can be used to remote control the device with Lightware Device Controller and establish the
connection to Lightware Device Updater software and perform firmware upgrade.

System controller
The following ways are available for device control:
Enable/
▪ The System controller can communicate with the Matrix via the TPS line of the Transmitter with using
LW2/LW3 protocol commands.
▪ The System controller can communicate directly with the Projector via their IP:port address.
▪ The Matrix can send commands (e.g. as an action by the Event Manager) to the IP:port address of the
Projector by using LW3 protocol commands. See Event Manager usage in the
and find the related LW3 protocol commands in the
