IEEE-488 Primary Address Selection

IEEE-488 Primary Address Selection

1.Assign a primary address to each power supply: Choose a number between 0 and 30 which is unique to your IEEE-488 bus, that is, different from other device addresses on the same bus.

2.Locate switch S1 on the GPIB interface rear panel. See “GPIB Interface Subplate” on page 21 for the interface subplate drawing.

3.Use switch positions A1 to A5 to set the primary address for the power supply. See Table 2.2, “IEEE-488 Primary Address Selection”.

Switch 0 = (OFF, OPEN) Switch 1 = (ON, CLOSED)
