The amount of data that can be transmitted at one time depends on the type of data, and
data will be transmitted from the specified starting address and size. Refer to the address
and size given in “Parameter Address Map” (p. 109).
*
Data larger than 256 bytes will be divided into packets of 256 bytes or less, and each
packet will be sent at an interval of about 20 ms.
*
Regarding the checksum, please refer to p. 112.
