2. The meter use RS-232 interface standard (point-to-point communication).
3. When “W” command is given, a reset is necessary to initiate the command.
4. Each byte consist of 8 bits.
5. “ “ (blank) in bit pattern information means the bit is not applicable to that parameter.
Note that all ranges have been given decimal numbers. To make a data
command, the decimal numbers converted into a hex numbers and then the
digits of that hex number are encoded into their equivalent ASCII values.
5.7.1 Input Type (Command Index 07)
Description: INPUT.76543210 means 8 bit positions of the Command Data.
