19、td 1174-2000, IEEE Standard Serial Interface for ProgrammableInstrumentation.)The development of this standard began with an ambitious plan to layer IEEE Std 488.1-1987 and IEEE Std488.2-1992 so that several media could take advantage of the installed base of IEEE 488 protocols. Thisinitiative was t
20、aken in cooperation with the IEC/SC65C Working Group 3 (WG3). It appeared that this wasnot possible without a considerable change of the format of the IEEE 488 standards. This was considered asundesirable. Therefore, the scope was much reduced to just the support of what is popularly known as the“RS
21、-232 serial interface” which is ubiquitous on personal computers. This standard draws from existingstandards as much as possible but seeks to provide a standardization for an instrument design that choosesthe slower speed serial communication because of the simplicity of the interface, the availabil
22、ity of most anypersonal computer as a controller, or other factors. At the time of the publication of this standard, the members of the Working Group were:Robert S. Cram,ChairIn the development of this standard, the Working Group was supported by many other individuals frommany different organizatio
23、ns who contributed time, effort, and technical expertise. In particular, the WorkingGroup wishes to acknowledge the following individuals for their contributions:The following members of the balloting committee voted on this standard:Stephen GreerSteve LomasJoe MuellerJohn PieperCarsten SchillingJoc

Clause 5 denes techniques to emulate IEEE St
35、d 488.1-19871which are suitable for controlling programmable instruments over a serial interface as dened inClause 4. Clause 6 denes techniques to emulate IEEE Std 488.2-1992 which are suitable for controllingprogrammable instruments over a serial interface as dened in Clause 4 and Clause 5. In conj
36、unction, Clause4 through Clause 6 form a set describing a method for ASCII-based communication over a serial linkbetween a controller and a device using concepts found in IEEE Std 488.2-1992. Figure 1 shows therelationship among the standards. Annex A describes a state machine implementation which f
37、ollows therules of Clause 6, and Annex B summarizes the allowed Performance Classes to an IEEE 1174 interface.1.1 ScopeThis standard denes a serial, full-duplex, asynchronous, 9-pin data terminal equipment (DTE) communica-tions port that follows ANSI/TIA/EIA-574-1990 and related standards.
