Event Creating - Example
The following example shows you on a real-life situation how to set up an Event.
The Concept
The MMX6x2-HT220 matrix is
connected to a projector by the
HDMI out 1 port. The matrix is
also connected to the projector
by the RS-232 port and can send
commands via the serial line.
The task is to turn on the projector
when signal is detected on the
HDMI out 1 port.
RS-232 Settings
Make sure that the serial line is established between the matrix and the projector. Check that the RS-232
settings of the matrix is set exactly the same which required for the projector: baud rate, data bits, parity,
stop bits. The matrix needs to be set to: Control protocol: LW3; and RS-232 mode: Control. See the relevant
section.
CONDITION

Setting the Event
You can create the Event in the Wizard in few simple
steps:
Step 1.
Set the condition.
Select the required parameters to set the condition:
▪
Category
: Video;
▪
Expression
: Signal is detected on a port;
▪
Port
: O1.
Click on the
Apply
button to complete the procedure.
When it is done, the condition appears on the upper
side in textual and LW3 command format as well.
Step 2.
Set the action.
If the condition is fulfilled, the following action needs
to be launched: the receiver sends a command to
the projector over the serial line:
▪
Power on
- the required command which is
accepted by the projector: PWR0<CR><LF>
For this instance the command has to be closed
with the <CR><LF> characters so they need to be
escaped. You can use the following format for
escaping:
<command
1
><\x0d\x0a><command
2
><\x0d\x0a>...
...<command
n
><\x0d\x0a>
In the current case the command is: PWR0\x0d\x0a
Select the required parameters to set the action:
▪
Category
: RS-232;
▪
Expression
: Send RS-232 message;
▪
Port
: P1;
▪
Message
:
PWR0\x0d\x0a
Step 3.
Enable the Event.
Select the
E1 enabled
pipe in upper left corner to set the Event as launched.
INFO: If you do not find the required category/expression/etc what you need, choose the Advanced mode
in the Wizard where the entire LW3 structure tree is available. For example instead of signal detection you
can set a specified resolution or color range either as a condition.
