4. Device Concept
4.11.2. RS-232 Recognizer
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 passed 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 MMX4x2 has an active video signal, the switcher logs in the VC codec automatically.
When the active signal is present on the output of the MMX4x2, it triggers a bi-directional communication
with the VC codec via RS-232:
ç MMX4x2 (starts the communication on RS-232): PING
æ VC codec (requests the login name): Login name:
ç MMX4x2 (sends the login name): Admin
æ VC codec (requests the password): Password:
ç MMX4x2 (sends the password): Admin
First configure the recognizer for the serial communication, after that set the events in the Event Manager.
The RS-232 recognizer settings can be arranged by LW3 protocol commands (see more information in
RS-232 Message Recognizer section).
Create the following events in the event manager:
E1. When the signal is present on O1 port of the MMX4x2, it sends a message 'PING' on P1 port of RS-232 to
the VC codec. For more details, see RS-232 Message Recognizer
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
section.

MMX4x2 series – User's Manual
4.12. Messaging Options
MMX4x2 devices offer many ways to communicate with other devices. The figure below shows the possibilities:
INFO:
In case of MMX4x2-HT200, the communication channels above are available via the TPS port, too.
4.13. Batch Commands
DIFFERENCE:
The features mentioned below are available from firmware v1.6.0b19.
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 them 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 MMX4x2. See more information in the
Messaging Options – Sending and Receiving
34
Macros section.
