Event Creating - Example
The following example shows you on a real-life situation how to set up an Event.
The Concept
The UMX-HDMI-140 is connected
to a projector by the HDMI
output port. The switcher 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 output port.
RS-232 Settings
Make sure that the serial line is established between the switcher and the projector. Check that the RS-232
settings of the switcher is set exactly the same which required for the projector: baud rate, data bits, parity,
stop bits. The switcher needs to be set to: Control protocol: LW3; and RS-232 mode: Event Manager. See 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:
<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.
