.Data Transfer
The PR-300S transmits "Data set I (DTI)" messages when receiving a proper "Request Data 1 (RQ I)" message. Refer to Section I (System
Exclusive Messages).
*The PR-300S only recognizes the DTI messages whose address and size match the Parameter Address Map.
*To send large DTI messages at
a time, insert intervals at least 40ms in size between each packet.
*The error checking process uses a Checksum.
