Instrument-Specific System Exclusive
Messages
20 Format
This section explains the format of the Instrument-specific System Exclusive Messages. See “V Parameter
List” and “VI Parameter Set List” for information about how parameter sets actually are transferred.
20.1 Message Classifications
Basically, the operation that corresponds to Instrument-specific system exclusive messages is parameter
data transfer.
The following operations can be performed from an external device using this parameter transfer
message.
Modification of an individual Instrument parameter
Batch modification of a particular Instrument parameter set
Import of an individual Instrument parameter value
Batch import of a particular Instrument parameter set
In addition to parameters being used as device setting values, some parameters act as commands
when received by the Instrument and as device status information when sent from the Instrument.
The following table shows the parameter category for each type of transfer.

20.2 Basic Message Structure
Instrument-specific system exclusive message operation can be broadly divided between two methods:
Individual Parameter Transfer (single parameter send/receive) and Bulk Parameter Set Transfer (batch
parameter send/receive). Each method includes a number of different messages.
The field in the system exclusive message that specifies the message type is the action (act ) field.
The format of the body part of the message depends on the act value.
