4. Device Concept
4.11. GPIO Interface

DIFFERENCE: This section refers to the MMX4x2-HDMI-USB20-L model only.
The General Purpose Input/Output (GPIO) port is a multifunctional input/output interface to control the
matrix switcher or third-party devices and peripherals. You can establish the connection between the
controller/controllable device and the matrix switcher by the 8-pole Phoenix connector. The direction of the
six pin is configurable independently from each other.
GPIO Options - Example
The Concept
Ceiling lamp is turned off by Relay 1 and projection screen is rolled down by Relay 2 when signal received
from the PC over the HDMI input. Both relays are controlled by the GPIO port.
Settings of the Transmitter
▪ For Relay 1: create an event in Event manager: when signal is present on Input 1 (I1) then set GPIO pins
to low level for Relay 1 opening. Also create another event when signal is not present on Input 1 (I1)
then set GPIO pins to high level for Relay 1 closing.
▪ For Relay 2: create an event in Event manager when signal is present on Input 1 (I1) then set GPIO pins
to high level for Relay 2 closing. Also create another event when signal is not present on Input 1 (I1)
then set GPIO pins to low level for Relay 2 opening.
When the PC starts to play the video presentation, the signal is received over the HDMI input so GPIO pins
send signal to Relay 1 to open which results turning off the lights. Furthermore, GPIO pins also send signal
to Relay 2 to close and the projection screen is rolled down. When the presentation is ended, signal ceases
on the HDMI input, so GPIO pins send signal to Relay 1 to close which results turning on the lights and sends
signal to Relay 2 to open so projection screen returns to its enclosure.
ATTENTION!
Please always check the electrical parameters of the devices what you want to control. The
maximum current of one GPIO pin is 30 mA, the maximum total current for the six pins is 180 mA.

4.12. Further Built-in Features
4.12.1. Automatically Launched Actions – The Event Manager
The Event Manager feature means that the device can sense changes on its ports and
is able to react according to the pre-defined settings. Lightware Device Controller
contains a user-friendly software tool and allows to create Events by defining a
Condition and an Action.
See more information about the settings in the
4.12.2. Matrix Cloning – Configuration Backup and Restore
The device (configuration) cloning of MMX4x2 series matrix is a simple method that eliminates the need to
repeatedly configure certain devices to have identical (non-factory) settings. If the devices are installed in
the same type of system multiple times then it is enough to set up only one device to fit the user's needs and
then copy those settings to the others, thus saving time and resources.

4.12.3. Advanced EDID Management
Factory Preset EDIDs
The factory EDIDs (F1-F120) are factory preprogrammed and cannot be modified. These are the most
common resolutions. They are specially provided to force graphic cards to output only the exact pixel
resolution and refresh rate.
Universal EDID allows multiple resolutions including all common VESA defined resolutions. The use of
universal EDID is recommended for fast and easy system setup.
