6.11.6. Creating and Event - Example
The following example shows how to set up an Event in a real-life
situation.
The Concept
The MODEX receiver is connected to a projector through the HDMI
output. The device is also connected to the projector through an RS-
232 port and can send commands via the serial line.
The task is to turn on the projector when a signal is detected on the
HDMI output port.
CONDITION
HDMI OUT
Signal is detected
on HDMI output
RS-232 Settings
Make sure that the serial link is established between the receiver and
the projector. Check that the RS-232 settings on the receiver is set
according to the requirements of the projector (baud rate, data bits,
parity, stop bits). See the relevant LDC software setting in
section.
Set the Event
You can create the Event in the Wizard in a 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 switcher sends a
command to the projector over
the serial line:
Power on - the required
command
accepted by the projector:
PWR0<CR><LF>
In this example the command has to be closed with the <CR><LF>
control characters. These are special characters so they need to be
ACTION
escaped with the \x sequence. You can use the following format for
escaping:
<command
><\x0d\x0a><command
1
Turn on the projector
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
RS-232 Layer
Step 3. Enable the Event.
Select the E1 enabled check box in upper left corner
to set the Event as launched.
INFO: If you do not find the required category/expression/etc. that
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 either set a specified resolution or color range as
a condition.
