Table 6-2. Actions of the Event Manager Wizard
* Referring to UMX-TPS-TX-140. Exact port numbers can be found in section 11.5 on page 123 .
** Messages may contain control characters e.g. carriage return or line feed, but in these cases the
controlling characters have to be escaped. Escaping means injecting a backslash
(‘\’) before the
character that should be escaped (like in C language). Control characters are the followings: \ { } #
% ( ) \r \n \t. When using the LDC, the escaping is done automatically. If you send a command from
a third party device/terminal to the transmitter, the escaping has to be done manually: put the extra
backslash before the control character. E.g. CALL /MEDIA/UART/P1:SendMessage(Message\\r\\n).
6.9.3. Advanced mode
The goal of this mode is the same as of the wizard: set the properties and methods for
conditions and actions. The difference is the number of the available and usable properties
and methods of the LW3 protocol. Advanced mode allows almost all of it.
Step 1.
Click the Advanced button. A new window comes up.
Step 2.
Select the desired node and the property; on the left side there is the closed LW3
tree of the device. To open it, click on the plus or folder sign (in the red square).
