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});.*
