IMPORTANT:
The data field in the Read and Write Request and
Response messages must and will only contain the
characters ‘0’-’9’, and the decimal point ‘.’. All other characters are
considered illegal. When the data field is listed as
Unused
or
Ignored
in an auxiliary command, it does not mean that the field
can be skipped when sending in the request message. Instead, this
field must be padded with any 10 alphanumeric (only letters and
numbers are allowed) ASCII characters.
