4. Device Concept
IR Signal Transmission - Example
The Concept
An IR detector is attached to the Infrared input port of the switcher and IR signals are sent by the Remote
controller. The switcher has two A/V sources (a Blu-ray player and a MacBook) and an A/V sink device (an
HDTV).
UMX-HDMI-140 switcher's input can be routed by the remote controller the following way:
Step 1. Make the Switcher learn the IR codes of the desired remote control buttons, see the
(hash) section.
Step 2. Arrange the events in Event Manager; if the set IR code is received from the IR input (condition), then
switch the input source between the Blu-ray player and the MacBook (action) in the Switcher. In this case
you can control the HDTV via the Switcher remotely. See the details about the Event Manager settings
in the Event Manager section.
Advanced IR functionality
DIFFERENCE:
This feature is available only in UMX-HDMI-140-Plus model.
UMX-HDMI-140-Plus can send Little-endian pronto hex IR codes on its IR output port.
It is possible in the following ways:
▪ With Lightware Device Controller software (for more details see
format) section)
With Event Manager (for more details see
▪
Manager section)
▪ With LW3 protocol command (for more information see
Format via IR Port)
Sending Bigger-endian pronto hex code is also available, see
Format via IR Port.
4.5.4. Ethernet Control Interface
The device can be controlled over front panel Ethernet port (standard RJ45 connector). This interface
supports any third-party system controller with both LW2 and LW3 command protocols.
The interface can be used to configure the device with Lightware Device Controller and establish the
connection to Lightware Device Updater software and perform firmware upgrade.

UMX-HDMI-140 series– User's Manual
4.5.5. GPIO Interface
The GPIO (General Purpose Input/Output) port is a multifunctional input/output interface to control the
switcher or third-party devices and peripherals. You can establish connection between the controller/
controllable device and the switcher by the 8-pole Phoenix connector. Seven pin's direction is configurable
independently based on needs of the application.
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 VGA input. Both relays are controlled by the GPIO port.
Settings of the Switcher
▪ 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)
Event 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 VGA 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 VGA 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 seven pins is 180 mA.
