USB Interface
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 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.

Switching USB Peripherals to Another PC – Example
.
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
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 as needed by setting the /MEDIA/USB/USBSWITCH.

or

.
It can be established by sending an
LW3 command
by an external device, e.g. RAP-B511 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 output 1.
4.7.
Ethernet Interface
The device can be controlled over the Ethernet port(s). This interface supports both LW2 and LW3 protocols.
4.7.1.
Device Control over Ethernet
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 update.
Third-party Device Control via Local Ethernet (Example)
The following ways are available for device control:
▪
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
section.
