Setting the Logical Address
The logical address switches 8 through 1 correspond to the GPIB-VXI's logical address bits 7
through 0, respectively. The
ON
position corresponds to a bit value of 0, and
OFF
corresponds
to a value of 1. For example, to set the logical address of the GPIB-VXI to 25 (19h), set the
switches as shown in Figure 2-2. Notice that setting the logical address to any setting but 0 will
disable the GPIB-VXI RM.
