5. Device Concept
The concept
The System controller can send commands (input/output switching, control functions, etc.) to the matrix
and is able to remote control the HDTV via RS-232.
Settings
Matrix: The RS-232 interface of the TPS OUTPUT 1 (P4) is in Command Injection (CI) mode. Set the further
parameters (Baud rate, Data bits, etc.) in accordance with the specifications of the television.
All settings are available in the LDC software, see
5.7.2.4. TTL Serial
The 2-pole Phoenix connector can be both infra or serial output. For TTL data transmission the destination
port numbers are 8003 and 8004. No setting required for configuring the interface, it works automatically.
Logic low level
Logic high level
Serial Output Voltage Levels (TTL and RS-232)
*Using a receiver with at least 1k impedance to any voltage between 0V and 5V to get the voltages.
5.7.3. RS-232 Recognizer
DIFFERENCE:
Below mentioned feature is available from FW package v1.1.0.
This tool is able to recognize and store the incoming RS-232 message until the previously defined string
(delimiter) has arrived or the timeout has come after the last data. The last incoming serial data is stored
and it can trigger an action in Event Manager.
RS-232 Recognizer Example
When the MMX8x4 has an active video signal, the switcher logs in the VC codec automatically.
When the active signal is present on the output of the MMX8x4, it triggers a bi-directional communication
with the VC codec via RS-232.

MMX8x4-HT series – User's Manual
The communication between the matix switcher and the VC codec is the following:
ç MMX8x4 (starts the communication on RS-232): PING
æ VC codec (requests the login name): Login name:
ç MMX8x4 (sends the login name): Admin
æ VC codec (requests the password): Password:
ç MMX8x4 (sends the password): Admin
First, configure the recognizer for the serial communication, then set the events in the Event Manager.
The RS-232 recognizer settings can be arranged by LW3 protocol commands (see more information in the
RS-232 Message Recognizer
Create the following events in the event manager:
E1. When the signal is present on O1 port of the MMX8x4, it sends a message 'PING' on P1 port of RS-232 to
the VC codec.
E2. Set a condition where Login name: is the recognized RS-232 message. Action is sending serial message
('Admin') on the P1 port to the VC codec.
E3. Set a condition where Password: is the recognized RS-232 message. Action is sending serial message
('Admin') on the P1 port to the VC codec.
For more information about setting the events, see the
5.8. Batch Commands
DIFFERENCE:
Below mentioned features are available from FW package v1.3.0.
These features can be used to process a group of pre-defined commands. The commands can be stored
in the device as macros or you can save the commands in a plain text file and send the device by an HTTP
message.
LW3 over HTTP (Command Salvo)
This feature allows the LW device to be controlled over HTTP. In this case, a batch of commands is sent
over HTTP to the Lightware device for processing. Save the LW3 commands into a file, post it to the
<IP_address>/protocol.lw3 file and the commands are processed immediately.
Running Macros
In this case, the command sequences (macros) are stored in the device. You can create your custom macros
in a file, upload into the device and run at any time. The number of the macros depends on the device type, at
most 50 macros can be saved in an MMX8x4 device. See more information about the feature in the
section.
