* The amount of data that can be transmitted at once time will depend on the type of data,
and data must be requested using a specific starting address and size. Refer to the
Address and Size listed in "Parameter Address Map" (p. 208).
* Data larger than 128 bytes must be divided into packets of 128 bytes or less. If "Data Set
1" is transmitted successively, there must be an interval of at least 40 ms between
packets.
* Regarding the checksum please refer to p. 212.
