Tcp Recognizer; Wake-On-Lan; The Event Manager Feature - Lightware MMX4x2 Series User Manual

4. Device Concept
4.7.2. TCP Recognizer
DIFFERENCE:
The features mentioned below are available from firmware v1.6.0b19.
The feature is almost the same as in case of the RS-232, but for the network interface: the incoming TCP
messages can be processed, which may trigger actions. The combination of the TCP recognizer and the
Event Manager gives numerous opportunities for creating automatic room solutions.
TCP Recognizer Example
When the Projector switches off, the button light (1) of the TBP6-EU button panel is turned off automatically.
When the power-off process is started in the projector, it will send a message over Ethernet. That message
will be recognized by the MMX4x2 switcher and will be used as a Condition in Event Manager.
How to set up the switcher?
Step 1. Configure the recognizer for the communication by the LDC, (see the
protocol commands (see the TCP Message Recognizer
client. (The Projector is saved as 'C1' in this example.)
Step 2. Create the following event in the Event manager:
E1. When the (PWR!001 "On") message is recognized from the C1 client, the GPIO pin 1 is set to
low level.
For more information about setting the events in LDC, see the
4.7.3. Wake-on-Lan

DIFFERENCE: This feature is available from FW package v1.6.0b19.
The well-known wake-on-lan feature (sending magic Packet to the target PC) is available. This can be used
to power on a computer automatically: just send a simple LW3 command, see the
over Ethernet (Wake-on-LAN) section.

INFO: Please make sure the feature is enabled in the target PC and it is powered (but switched off).

4.8. The Event Manager Feature
The Event Manager feature means that the device can sense changes on its ports and is able to react
according to the pre-defined settings. Lightware Device Controller contains a user-friendly software tool and
allows creating Events by defining a Condition and an Action.

DIFFERENCE: The features mentioned below are available from firmware v1.6.0b19.
The AND Operator
The practical experience has shown that there is a need to examine more conditions (up to four) as follows:
if one of the set conditions becomes true (while the other conditions are fulfilled), then the set Action is
launched. For example, in a meeting room we have the following situation:
▪ Signal is present on an input port,
▪ A GPIO pin state becomes 'low' (by an external device).
If the two Conditions are present at the same time, the Action is launched. Just create the two Conditions into
separate Events, then create a third Event, select the two Conditions and define the Action.
See the Combine Links section for the settings in LDC.
Event Manager Variables
A brand new area is opened by implementing the variables. You can create custom variables in number
or text format, which can be used in the Event Manager. The variables can have the following properties/
methods:
Numeric (integer) type with min/max value setting, or string-type (determined automatically)
▪
Increment/step the numeric value,
▪
Value-dependent case operations,
▪
Reading and storing the value of an LW3 property into a string or a numeric variable.
▪
The defined variables are stored in a non-volatile memory and the value is kept in case of a reboot. The
new opportunities allow creating a monitoring/controlling system without connecting an additional control
processor.
See the Variables section for the settings in LDC.
