7.10. RS-232 Recognizer
DIFFERENCE:
This feature is available only in UMX-HDMI-140-Plus model.
This tool is able to recognize the incoming RS-232 message. It stores the incoming serial data from the
first bit, until the previously defined string (delimiter) or the elapsing timeout after the last bit. The last
incoming serial string is saved in different formats (string, hex, and hash).

æ pw /MEDIA/UART/P1.RecognizerEnable=true
7.10.2. Set the Delimiter Hex
When the delimiter hex string is detected in the incoming serial
data, the device saves the RS-232 message data from the first
bit, until the delimiter (or the data between the two delimiter).
ç SET·/MEDIA/UART/RECOGNIZER.DelimiterHex=<delimiter>
pw·/MEDIA/UART/RECOGNIZER.DelimiterHex=<delimiter>
æ
