3 Operation Theory
This chapter describes the operation theory of GPIB bus and the
basic architecture of PCI-3488 GPIB interface card.
3.1 Connection Configuration
The GPIB bus has 24 lines, which are divided into 16 signal lines
and 8 ground return or shield drain lines. The 16 signal lines can
be divided into 8-bit parallel data transfer bus and 8 control lines.
These 8 control lines contain 5 system management lines and 3
handshake lines.
