Interconnections

Instruments fitted with an IEEE 488 interface communicate with each other through a
standard set of interconnecting cables, as specified in the IEEE 488.1 Standard document.
The interface socket is fitted on the rear panel. It accommodates the specified connector,
whose pin designations are also standardized as shown in Figure 4-1.
