4.6. Serial Interface
This section is about the serial interface of the endpoint device.
DIFFERENCE:
Only the UBEX-PRO20-HDMI-F110 model has built with serial interface port.

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. A TCP port in the MMU addresses an RS-232 port in the endpoint device. The user can set which
TCP port is ordered to the required RS-232 port.
INFO:
It does not matter which device of the Ethernet interface (the MMU directly or any endpoints) you
want to use establishing connection with the UBEX matrix, you will reach the MMU finally.
Setting up the TCP Ports of the Serial Interface
The default starting port number is 8000 and increases with one until the number of the RS-232 ports in
the matrix. If these TCP ports are reserved in the network, the port numbers can be changed in LDC (see
the details in the RS-232 Tab section) or using LW3 protocol command (see the details in the
Injection TCP Port Setting section).
TIPS AND TRICKS:
The TCP ports can be remapped with a single LW3 protocol command, see the details
in the Remap the Command Injection TCP ports

4.6.2. RS-232 Signal Transmission – Example
The Concept
The devices which are connected via RS-232 (4K TV, projector, audio amplifier) are controlled with serial
messages which are sent over Ethernet interface. All Ethernet devices can send messages to all controlled
devices. Up to three Ethernet devices can be connected per endpoints.
You can send serial messages using two methods:
▪ Lightware Device Controller (LDC) / Built-in Website - see the details in the
▪ LW3 protocol commands - see the details in the
RS-232 Tab section;
Message Sending via Communication Ports section.
