Preparation For
Use
Preparation for use includes removing the instrument from the
container box, selecting the required logical address and connecting
the instrument to the power line and to a host computer.
Logical Address
Selection
The GPIB Resource Manager identifies modules in the system by the
module’s address. GPIB logical addresses can range from 0 to 31,
however, addresses 1 to 31 only are reserved for GPIB instruments.
Logical address 0 is reserved for the GPIB controller.
To change the logical address, open the top cover and use the 8-
position DIP switch accessible from the top side of the generator near
the rear end of the case (switch S1). Figure 2-1 shows the location of
the logical address switch. The switches are marked with numbers 1
to 8. The Model 301/302 uses binary values (2
0
to 2
7
) to set the
logical address using the active low address switch. A switch is active
when its arm is placed in the ON position. Wavetek-Datron ships the
Model 301/302 with logical address 2.
