6.12.6. Event Creating - Example
The following example shows you on a real-life situation how to set up an Event.
The Concept
The 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
MMX8x4-HT series – User's Manual
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
LDC settings in the
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:
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:

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.
