●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 48H.

❍Data Request 1RQ1 (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.

* 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 Section 2, "Parameter address map (p. 7)."

* 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.

* 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 Section 2, "Parameter address map (p. 7)."

* 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. 19.
