Hi Paolo,
It looks to me like you should uncheck 'configuration is in hex'. If you are translating a 30 into a 0 and 33 into a 3, you are not transporting in hex, you are transporting in UTF-8 or ASCII or some such. And '0x0a' is \n
You may be able to get this to work via regex like...
DATA SOURCE: Use terminator: Yes Terminator: \n Message Regex: (\d+;)*([0-9]{4})[0-9]{4}.* Point Identifier Group: 1 Configuration in Hex: No DATA POINT: Data Type: Alphanumeric Point Identifier: 0103 Value Group: 1 Value Regex .*0103([0-9]{4});.*
