4.6.1. USB Control Interface
The device can be controlled over front panel USB port (mini B-type connector). This interface supports only
LW3 protocol. The interface can be used to establish a connection to Lightware Device Controller software.
4.6.2. 4x1 USB 2.0 Switch

DIFFERENCE: This section refers to the MMX4x2-HDMI-USB20-L model only.
The device contains a built-in USB 2.0 hub. USB host devices (e.g. PC-s) can be connected to the four USB
B-type connectors, and USB peripherals (e.g. camera, speakerphone, mouse, etc.) can be connected to the
four USB A-type connectors. You can switch the USB peripherals to connect one host device. Please note
that only one USB host can be active at the same time, thus, all the connected USB peripherals will be
connected to the same USB host device. The connected USB peripherals can be powered up to 500mA,
except at the first port where max. 1000 mA can be supplied.

ATTENTION! The sum of the current that the GPIO and the USB-A ports can supply together is max. 2A.

The Concept
The PC and the laptop are connected to USB B-type ports of the matrix switcher (HDMI connection is not
necessary for the USB functionality). USB peripherals (camera, microphone, keyboard and mouse) are
connected to the USB A-type ports. The user can select to switch the USB peripherals to the PC or to the
laptop.
Settings
#new
The PC is connected to the PC 1 USB B-type port, the laptop is connected to the PC2 USB B-type port.
Change the USB host device according to the needs by setting the /MEDIA/USB/USBSWITCH.HostSelect
property to 1 or 2. It can be established by sending an LW3 command by an external device, e.g. TBP6-EU
Button panel.
The function can be also combined with the Event manager to have a more comfortable automatic system:
when a USB host device is connected to the PC3 port, switch the HDMI input 3 to the output 1.
4.7. Ethernet 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 also used to remote control a third-party device and establish the connection to
Lightware Device Updater software and perform firmware upgrade.
Third-party Device Control via Local Ethernet (Example)
The following ways are available for device control:
Applied firmware package: v1.5.0b8 | LDC software: v2.3.0b1
▪ 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
27
Event Manager section,
Ethernet Message Sending section.
