  3. GPIB History(General Purpose Interface Bus) • GPIB was initially developed by HP, as it’s the interface between their own internal connection devices called HPIB. • In 1975, IEEE announced IEEE-488-1975 based on HPIB. (It standardizes electrical and mechanical characteristics between Connectors & Cables, and defines the data transmission Handshaking agreement among collecting buses). • In 1978, IEEE made the first revision called IEEE-488.1-1987 to define the firmware. • IEEE-488.2-1987 is a newly defined standard, it covers Standard Code, Format, Protocols and Common Commands for solving software compatibility problems.

  4. GPIB characteristics • GPIB can connect 15 instruments (0~31 address can be assigned) to a PC (controller). The PC handles the transmission on the bus. • 8 bits parallel transmission, up to 8 Mbits/s transmission speed. • The total cable length in a system should not exceed 20m (2m max. between a device and next device) • Text mode commands. (Easy to differentiate) • Using three handshake line for handshaking to ensure data transmission accuracy.

  5. PCI-1670 Introduction

  6. Specification • Supports Windows 95/98/Me/NT40/2000/XP and DOS OS. • Provides NI-like drivers & function libraries. • Supports Visual C++、Borland C++ Builder、Labwindows、Visual Basic、Delphi and Labview…etc. • Provides interactive control utility. • GPIBTool.exe • IEEE 488 bus transfer rates up to 1.5M bytes/sec. • ( Actual rates depend on instrument capabilities )
