3. Individual Parameter Transmission

Individual Parameter Transmission transmits data (or requests data) for one parameter as one exclusive message (one packet of “F0 ..... F7”).

In Individual Parameter Transmission, you must use the Address and Size listed in the following “Parameter Address Map”. Addresses marked at “#” cannot be used as starting addresses.

■System Exclusive Messages

When an appropriate “Data Request 1 (RQ1)” message is received, the requested internal data will be transmitted as “Data Set 1 (DT1)”.

* The amount of data that can be transmitted at one time will depend on the type of data, and data must be requested using a specific starting address and size.

* Regarding the checksum, refer to “5. Supplementary material”, Example of an Exclusive message and calculating a checksum (p. 19).

* 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.

* Data larger than 128 bytes will be divided into packets of 128 bytes or less, and each packet will be sent at an interval of about 40 msec.

* Regarding the checksum, refer to “5. Supplementary material”, Example of an Exclusive message and calculating a checksum (p. 19).
