Data Transmission
This instrument can use exclusive messages to exchange many varieties of internal
settings with other devices.
The model ID of the exclusive messages used by this instrument is 00H 00H 41H.
m Data Request 1 RQ1 (11H)
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.
