Setting the Logical Address, GPIB Primary Address, and Servant
Area Size
You can change the logical address, GPIB primary address, and Servant
area size by running the nonvolatile memory configuration utility as
described in the
Change Configuration Information
section of Chapter 4,
You can also change the logical address by setting DIP switch SW1.
By default, all the switches are set to the Up position (0xFF). At this setting,
the GPIB-VXI/C reads the logical address from the onboard EEPROM.
To change the logical address, set the switches to the hex value of the
logical address. Switch position 1 is the MSB; 8 is the LSB. Up is logical
1; down is logical 0.
Verifying the Installed RAM Size
The GPIB-VXI/C contains 4 MB of factory-installed local RAM but is
configured to use the minimum amount of 512 KB. Table 2-2 lists the
RAM configurations and their associated switch settings. You can use this
information to change the board configuration.
