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.
