2.3.4 IEEE 488 Address Selection

Digital488HS/32's IEEE 488 bus address is set by the switches labeled IEEE

ADDRESS on the rear panel of the unit. The address can be set from 0 through 30.

The address is selected by simple binary weighting, with the switch labeled 1 being

the least significant bit and the switch labeled 16 the most significant bit. The factory

default is address 18. If address 31 is selected, the interface is placed in the “Listen

Only” or “Listen Always” mode.
