5.4. Serial Interface
DIFFERENCE:
Only the UBEX-PRO20-HDMI-F110 model has built with serial interface port.
5.4.1. Technical Background
Port Diagram
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.
5.4.2. 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
series – Extender Application Mode – User's Manual series – Extender Application Mode – User's Manual

Applied F-series endpoint firmware package: v2.0.0 | Applied R-series endpoint firmware package: v2.0.0 | LDC software: v2.5.9b3
5.5. 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.
5.5.1. 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 section.
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
Infra Tab section) or LW3
Sending Hex Codes in Little-endian Format via IR Port
section).
