4.11.2. Advanced IR functionality
DIFFERENCE:
UMX-TPS-TX140-Plus, UMX-TPS-TX140K and WP-UMX-TPS-TX130-Plus-US 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.
4.12. GPIO Interface
4.12.1. Description
The GPIO (General Purpose Input/Output) port is a multi functional input/output interface to control the
transmitter or third-party devices and peripherals. You can establish connection between the controller/
controllable device and the transmitter by the 8-pole Phoenix connector. Seven pin's direction is configurable
independently based on needs of the application.
4.12.2. 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.

UMX-TPS-TX100 series – User's Manual
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.
Event
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.
See the LDC settings for GPIO port in the
settings in the Event Manager
4.13. The Event Manager Feature
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
GPIO Tab section. See also the details about the Event Manager
section.
