RS-232 Message Sending
The message in the field can be sent out via the
current RS-232 port. Response cannot be seen in
the surface.
ATTENTION!
The escaping is done automatically when sending a message via this surface. When the
message is an LW3 command, it has to be closed by Carriage return and Line feed, e.g.: CALL /MEDIA/
VIDEO/XP:switch(I1:O1)\x0d\x0a.
RS-232 Message Recognizer
This tool can be used to recognize messages coming
from the RS-232 port. The message can be used as a
Condition in Event manager and define an Action for it.
Definitions #message
Delimiter sequence (hex): Each message is closed by this
separator (if defined).
Accept timeout (ms): When the set time is elapsed after the
last received message and delimiter was not detected,
the device saves the data into the Text, Hex, and Hash
properties. The timeout setting is useful if there is no
special or easily defined delimiter in the incoming data,
but there is a time gap between the messages.
Text: The recognized message in ASCII-format.
Hex: The recognized message in hex format.
Hash: Binary data that is mapped from the original
message. The length of the hash is shorter, and the same
message results the same hash.
Working Method
A message got recognized from the incoming data, if one
of the following occurs:
▪ The set DelimiterHex is detected in the message, or
▪ The set TimeOut has been elapsed since receiving
the last data bit.
