store settings in registers designated with numbers
from 00 to 30.
*SRE (Service Request Enable Command) - fol-
lowed by a number, sets the Service Request Enable
register which determines what bit in the status byte
will cause a service request from the device. The
binary equivalent of the number represents the values
of the individual bits of the Service Request Enable
Register.
*TRG (Trigger Command) - has exactly the same
effect as a GET when received, parsed, and executed
by the device.
*WAI (Wait to Continue Command) - causes a
device to wait until all previous commands and
queries are completed before executing any which
follow the *WAI command.
4-10-7-1. Set-ups (*SAV, *RCL)
The setups commands select the memory location
where front panel setup is to be stored (*SAV) or
from where recalled (*RCL). To store or recall a
setup use one of the following commands:
*SAVnn
*RCLnn
Where nn may range from 00 to 30. nn is the
selected memory cell of which the setup is to be
stored or from where the setup is to be recalled.
4-11. DEVICE TALKING FORMATS
This paragraph discusses the formatting of <Response
Message> elements sent from a device via its system
interface. Allowable IEEE-488.2 response message
is composed of a sequence of <Response Message>
units, each unit representing a response to a query.
Each <Response Message> is composed of a se-
quence of functional syntactic elements. Legal IEEE-
488.2 <Response Message> is created from functional
elements sequences. A <Response Message is in-
terpreted by a controller running an application pro-
gram, and as such, needs to convey its information
precisely for consistent operation with a wide range
of controllers. A <Response Message>, therefore,
has a more restrictive format than a <Program
Message>.
Some queries of universal instrument system ap-
plication have been defined by the IEEE-488.2. They
are the common queries; these queries are specific
path selections through the functional syntax diagram
as specified in the IEEE-488.2 standard. The re-
maining queries are device-specific and are generated
by the device designer using the functional syntax
diagram and the needs of the device. The functional
elements include separators, terminators, headers,
and data types. These elements are discussed in
the following.
