Summary of Infra Ports

MMX8x4-HT420M
MMX8x8-HDMI-4K-A
INFO: The 2-pole Phoenix connector can be both infra or serial output. For infra data transmission the
destination TCP port numbers are 9001 and 9002. No setting required for configuring the interface, it works
automatically.
ATTENTION! The IR signal cannot be routed from an IR port to another IR port.
Technical background
The Infrared signal transmission is similar to the serial data communication. The matrix contains dedicated
IR output where IR code sending is possible. The matrix can receive IR signal via the Control Ethernet port.
The Infrared signal is in pronto hex format.
Getting IR codes
Getting IR code is possible from two sources:
▪ Download a code which belongs to your controlled device from a web database from the Internet. The
downloaded codes are mostly in little-endian format.
▪ Learn IR code (see the details below).
Learn IR code
Step 1. Connect a Lightware device which has IR detector unit (e.g. UMX-TPS-140) with a terminal program.
Step 2. Push the proper button of the remote control to scan the IR codes in hex format.
Step 3. Remove all the non-hexadecimal characters (e.g. spaces, h characters etc.) from the code.
INFO: The pronto hex code which learned by a Lightware device is big-endian format.
Sending Big-endian format pronto hex codes
With LW3 protocol command
Step 1. Connect the 6107 port of the matrix.
Step 2. Use LW3 protocol command to send the pronto hex code:
Ý CALL /MEDIA/IR/D1:sendProntoHexBigEndian(<prontohex>)
INFO: The maximum length of the code can be 765 characters (765 bytes). For more details about the
accepted IR code formats see

Sending Little-endian format pronto hex codes
With Lightware Device Controller software
Step 1. Connect the 6107 port of the matrix and open the LDC software.
Step 2. Choose the desired IR output in the control menu, on the infra tab.
Step 3. Copy the IR code into the Send Pronto Hex entry field and click the Send button.

Step 1. Connect the 6107 port of the matrix.
Step 2. Use LW3 protocol command to send the pronto hex code:

With Event Manager
Step 1. Connect the 6107 port of the matrix.
Step 2. Create an event in Event manager. After setting any condition, set the
Category: Infra; Expression: Send pronto hex; Port: D1-D6; Pronto hex: Insert the pronto hex code.
Sending IR code in Command Injection mode
When the data transmission is enabled, the output port works in command injection mode. The IR data
(in pronto hex format) is transferred between the LAN port and the IR port. Separate user-configurable
TCP/IP port numbers are defined for IR output ports for this purpose, see
The settings are available in the LDC software, see
section.

INFO: The maximum length of the code can be 765 characters (765 bytes). For more details about the
accepted IR code formats see Sending Pronto Hex Codes in Little-endian Format via IR Port
INFO: The maximum length of the code can be 184 characters (184 bytes).
