3. Product Overview UMX-TPS-TX100 series – User's Manual 35
Advanced IR functionality
IR output port.
It is possible in the following ways:
▪ Sending pronto hex codes (Little-endian
format) section)
▪ Sending pronto hex codes (Little-endian format) and Event
Manager section)
▪ Sending Pronto Hex Codes in Little-endian
Format via IR Port)
Sending Bigger-endian pronto hex code is also available, see Sending Pronto Hex Codes in Big-endian
Format via IR Port.
GPIO Interface
Description
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 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.
send signal to Relay 1 to open which results turning off the lights. Furthermore GPIO pins also send signal
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 GPIO Tab section. See also the details about the Event Manager
settings in the Event Manager section.
Ethernet Control Interface
The interface can be used to remote control the device with Lightware Device Controller and establish the
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 section.
CEC has a dedicated pin in the HDMI connector. DVI connector does not contain this pin, so the CEC
transmission brakes when HDMI-DVI connector or adapter is in the signal route.
