7.21.2. Set the Delimiter Hex
This property stores the delimiter that is between the messages (e.g. Cr, Lf, Space). The value has to be in
hex format (e.g.0D, 0A, 20).
Command and Response
SET·/MEDIA/UART/RECOGNIZER.DelimiterHex=<delimiter>
ç
pw·/MEDIA/UART/RECOGNIZER.DelimiterHex=<delimiter>
æ
Parameters
The <delimiter> parameter can be max. 8-character long (or 16 hex digit) in hex format.
Example
ç SET /MEDIA/UART/RECOGNIZER.DelimiterHex=3a
æ pw /MEDIA/UART/RECOGNIZER.DelimiterHex=3a
7.21.3. Set the Timeout
When the set time is elapsed after the last received message and delimiter was not detected, the device
saves the data into the Rx, RxHex, 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.
Command and Response
SET·/MEDIA/UART/RECOGNIZER.TimeOut=<timeout>
ç
pw·/MEDIA/UART/RECOGNIZER.TimeOut=<timeout>
æ
Parameters
The <timeout> parameter sets the timeout value in milli seconds: 0 means the timeout is disabled, min.
value is 10.
Example
ç SET /MEDIA/UART/RECOGNIZER.TimeOut=20
æ pw /MEDIA/UART/RECOGNIZER.TimeOut=20

TIPS AND TRICKS:
follow each other, the action will execute once. (A Condition can be detected in Event Manager if a change
happens. But if the same string is saved into the property after each other, it will not cause a change.)
