Important Safety Instructions
Please read the supplied safety instruction document before using the product and keep it available for future reference.
Introduction
MMX4x2-HDMI-USB20-L is an integrator-friendly, 4×2 matrix switcher for HDMI video and USB2.0 peripherals. It has four HDMI inputs and two independent HDMI outputs, as well as a USB 2.0 layer that provides the switching of four external USB peripherals (USB devices such as web camera, speakerphone, multitouch display, etc.) to four dependent host computers or laptops.
The device offers two individual RS-232 interfaces to allow independent control of two separate party devices, such as a Cisco Room Kit Mini or an external display. MMX4x2-HDMIUSB20-L and built-in Event Manager automation make the meeting room easy, intuitive, and hassle-free; it detects powered computers, turns on the screen and camera, and prepares for the next call. Based on the specific configuration it allows auto-switch for USB and video signals. In other cases, the USB may not follow the video, according to the application.

HDMI |
Connect the sink devices (e.g. Display) to the HDMI output ports of the matrix by HDMI cables. |
Audio |
Optionally connect an audio device (e.g. Active speakers) to the analog audio output port by an audio cable. |
LAN |
Optionally connect the matrix to a LAN in order to control the device and/or to connect further devices to the Ethernet. |
RS-232 |
Optionally connect the Display over RS-232 to send control commands from the matrix. |
USB |
Connect a USB host device (e.g. PC) to the USB-B (upstream) port of the matrix. |
USB |
Connect the desired USB peripherals (e.g. Bluetooth adaptor) to the USB-A (downstream) port of the matrix. |

Device concept
The MMX4x2-HDMI-USB20-L device is based on the previous MMX4x2-HDMI multifunctional audio/video matrix switcher (with four HDMI inputs and two HDMI outputs). The new model contains even more features like the built-in switchable USB hub, the GPIO port, and further connectors for additional Ethernet- and RS-232 serial devices.
+ Ethernet (3x)
+ USB hub (4×4)
+ Local USB
+ RS-232
+ GPIO
USB Interface
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, house, etc.) can be connected to the four USB A-type connectors. You can switch the USB peripherals to connect to 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.

Typical Application
GPIO – General Purpose Input/Output Ports
The device has six GPIO pins which operate at TTL digital signal levels and can be set to high or low levels (Push-Pull). The direction of the pins can be input or output (adjustable). The signal levels are the following:
| Input voltage (V) | Output voltage (V) | Max. current (mA) | |
| Logical low level | 0 – 0.8 | 0 – 0.5 | 30 |
| Logical high level | 2 -5 | 4.5 – 5 | 18 |
The total available current for the six pins is 180 mA.
