10.3 Command Interpreter
The RDS encoder command interpreter meets the following rules:
Any instruction sent to the RDS encoder must be validated by <Enter>.
Before validating you may correct the characters by pressing <Backspace>.
There are several methods of use for the commands:
Query or command without argument, ex.
HELP
Shows the parameter value or performs the operation.
Command with argument, ex.
ECHO=1
Assigns the value to the parameter.
Memory store command, ex.
*ALL
Stores the parameter value(s) into the non-volatile EEPROM memory.
Memory store command with argument, ex.
*MSG01=
Assigns the value to the parameter and stores it immediately into the non-volatile EEPROM memory.
Not all methods are available for all commands, see Command Summary section.
Depending on the command processing success, several characters (followed by two pairs of carriage return and
line feed characters) can be returned by the RDS encoder:
+
Command processed successfully
!
Unknown command
-
Invalid argument
/
Command processed partially
The command interpreter is not case sensitive. But it’s recommended to write all commands in UPPER CASE
to maintain backward compatibility with older firmware versions.
If you wish to retain change of any parameter value during power off, don’t forget to store it into EEPROM memory!
