The Concept
The endpoint device uses command injection which means in the practice it works as a TCP/IP -> RS-232
converter so the TCP/IP data signal is converted to RS-232 data. The serial message is sent over the
Ethernet interface (via the Gigabit Ethernet 1-3 ports) which addresses the local or the remote RS-232 port.
TCP/IP port numbers are defined for the serial ports for this purpose. E.g. the default Command Injection
port number of the local RS-232 port is 8001. If data is coming from the SFP+links which addresses to the
port no. 8001, it will be transmitted to the Tx pin of the local RS-232 port.
4.4.2. RS-232 Signal Transmission – Example
The Concept
The projector which are connected to the UBEX receiver is controlled with RS-232 messages which are sent
from the PC connected to the UBEX transmitter. You can send serial messages in text, hexa, and binary
format using two methods:
▪ Lightware Device Controller (LDC) - see the details in the
▪ LW3 protocol commands - see the details in the

4.5. Infrared Interface
DIFFERENCE:
Only the UBEX-PRO20-HDMI-F110 model has built with Infrared interface ports.
ATTENTION!
The device has no built-in Infrared receiver and transmitter. For the complete usage attach
the supplied IR emitter unit to the IR OUT and the IR detector unit to the IR IN connectors.
4.5.1. Technical Background
Port Diagram
The endpoint device uses
command injection which means in
the practice it works as a TCP/IP
-> Infrared converter so the TCP/
IP data signal is converted to
Infrared code. The Infrared code
can be received from the IR in
port or it is sent over the Ethernet
interface (via the Gigabit Ethernet
1-3 ports) which addresses the IR
out port of the remote endpoint
device. TCP/IP port numbers are
defined for the IR output port
for this purpose. E.g. the default
Command Injection port number
of the IR out port is 9002. If data
is coming from the SFP+links
which addresses to the port no. 9002, it will be transmitted to the IR output port.
INFO:
The modulation of output IR signal can be turned off or on by LW3 protocol command, see the
Enable/Disable Output Signal Modulation
Infrared Message Sending
Infrared message can be sent over the IR output port in two formats:
▪ Pronto hex message in little-endian format using LDC (see the details in the
protocol command (see the details in the
section);
▪ Pronto hex message in big-endian format using LW3 protocol command (see the details in the
Hex Codes in Big-endian Format via IR Port

section.

Sending Hex Codes in Little-endian Format via IR Port
section).
