7. LW3 Programmers' Reference
7.11.6. Query the Last Recognized Serial Message (ActiveRx,
ActiveRxHex, ActiveHash)
The recognized data is stored in string, hex and hash format in a
temporary storage. They are erased when the Active Timeout elapsed.
TIPS AND TRICKS: When these properties are set as a condition
in the Event Manager, and the same strings follow each other, the
action will execute every occasion if the active timeout set properly.
Recognized data in string format
Ý GET·/MEDIA/UART/RECOGNIZER.ActiveRx
·
Ü pr /MEDIA/UART/RECOGNIZER.ActiveRx=<recognized _string>
Parameters
<recognized _string> Max. 12 byte-long recognized data string.
Example
Ý GET /MEDIA/UART/RECOGNIZER.ActiveRx
Ü pr /MEDIA/UART/RECOGNIZER.ActiveRx=Login:
Recognized data in hex format
Ý GET·/MEDIA/UART/RECOGNIZER.ActiveRxHex
Ü pr·/MEDIA/UART/RECOGNIZER.ActiveRxHex=
Parameters
<recognized _hex> Recognized data in hex format.
Example
Ý GET /MEDIA/UART/RECOGNIZER.ActiveRxHex
Ü pr /MEDIA/UART/RECOGNIZER.ActiveRxHex= 4C6F67696E3A
Recognized data hash
Ý GET·/MEDIA/UART/RECOGNIZER.ActiveHash
Ü pr·/MEDIA/UART/RECOGNIZER.ActiveHash=
Parameters
<recognized _hash> Fingerprint code, Max. 32 bit-long recognized data
hash.
Example
Ý GET /MEDIA/UART/RECOGNIZER.ActiveHash
Ü pr /MEDIA/UART/RECOGNIZER.ActiveHash= 2D8A5E38
7.11.7. Set the Active Timeout
This property is responsible for erasing the temporary storage
(ActiveRx, ActiveRxHex, ActiveHash) after the elapsing time. Default
value is 50ms.
SET·/MEDIA/UART/RECOGNIZER.ActivePropertyTimeout=<a_timeout>
Ý
pw·/MEDIA/UART/RECOGNIZER.ActivePropertyTimeout=<a_timeout>
Ü
Parameters
<a_timeout> active timeout value (ms) between 0 and 255.
Example
Ý SET /MEDIA/UART/RECOGNIZER.ActivePropertyTimeout=255
Ü pw /MEDIA/UART/RECOGNIZER.ActivePropertyTimeout=255
