Commands List
Some commands include indexes or passwords and parameters. Indexes or passwords are sent enclosed with “[]”and are coded in decimal, if numbers. Parameters are enclosed with “()” and the codification depends on the command. The default password is “PIC” but can be changed modifying the application source code. Examples:
- Example 1: DCW [10] (100000) writes 0x100000 in the control register with index equal to 10
- Example 2: IDW [PIC] (12345Q) sets the Meter Identifier to 12345Q
If the command is not properly received, decoded or processed by the application, the console will return an error message, like “Unsupported Command”, “Password Error”, ...
These are the supported commands:
