Data Request 1 RQ1
This message requests the other device to transmit data. The address and size indicate the
type and amount of data that is requested.
When a Data Request message is received, if the device is in a state in which it is able to
transmit data, and if the address and size are appropriate, the requested data is
transmitted as a Data Set 1 (DT1) message. If the conditions are not met, nothing is
transmitted.
The model ID of the exclusive messages used by this instrument is 00 0BH.

* For the address, size, and checksum, refer to "Examples of system exclusive messages
and calculating the checksum" (p. 253).
* Data whose size is greater than 128 bytes should be divided into packets of 128 bytes
or less and transmitted. Successive "Data Set 1" messages should have at least 20 ms of
time interval between them.
* This message is not received if the Rx.System Exclusive Switch parameter is OFF.
The only GS exclusive messages received by the JX-305 are Scale Tune settings (p. 253).
