3. Product Overview
3.15.4. Advanced IR functionality
UMX-TPS-TX140-Plus and WP-UMX-TPS-TX130-US-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.
3.16. GPIO Interface
3.16.1. Description
The GPIO (General Purpose Input/Output) port is a multifunctional 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.
3.16.2. GPIO Options - Example
Ceiling lamp Relay 1
VGA IN
VGA IN
PC UMX-TPS-TX140 transmitter
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 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.
and 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.

3.17. Ethernet Control Interface
The device can be controlled over front panel Ethernet standard RJ45 connector which connected to LAN.
This interface supports both LW2 and LW3 protocols.
The interface can be used to remote control the device with Lightware Device Controller and establish the
connection to Lightware Device Updater software and perform firmware upgrade.
3.18. Consuming Electronic Control (CEC) Interface
INFO: This feature is available only in UMX-TPS-TX140-Plus and WP-UMX-TPS-TX130-US-Plus models.
Consumer Electronic Control (CEC) is a bi-directional communication, defined in the HDMI standard. This
Projection
feature is for remote control of the source and sink devices in the A/V system.
screen
UMX-TPS-TX140-Plus model is able to send and receive CEC commands, on HDMI IN (I2) port towards the
source, on HDMI OUT (O1) port towards the sink. For more information about sending CEC messages, see
Sending CEC Commands
CEC has a dedicated pin in the HDMI connector. DVI connector does not contain this pin, so the CEC
