Using and Troubleshooting the GPIB-VXI/C

Changing the GPIB Address of the GPIB-VXI/C

This section describes how to change the GPIB address of your GPIB-VXI/C. Below is an example that illustrates the procedure to change the GPIB address of the GPIB-VXI/C.

The following prompt will appear, type the command "conf"

GPIB-VXI>conf

This command will bring up the following menu:

================================================

1). Read In Nonvolatile Configuration

2). Print Configuration Information

3). Change Configuration Information

4). Set Configuration to Factory Settings

5). Write Back (Save) Changes

6). Quit Configuration

Choice (1-6): 3

Select 3 as your choice. This will cause a second menu to appear.

1). Edit pSOS Configuration

2). Edit VXI Interrupt Handler Logical Addresses

3). Edit Resource Manager Configuration

4). Edit Servant Area and DC Configuration

5). Edit FAILED Device Handling Mode

6). Edit GPIB Configuration

7). Edit Default CI Configuration

8). Edit Resident CI Base Locations

9). Edit CI User Configuration Variables

Q). Quit Editor

Choice (0-9,Q): 6

Select 6 as your choice and you will be prompted to enter the following information:

----- GPIB Configuration -----

GPIB mode: multiple P)rimary or S)econdary addrs (default SECONDARY): SECONDARY

Enter MASK for GPIB Addresses to Avoid (default 0x00000000):

GPIB Primary Address (default 0x1): 2

GPIB Address Assignment Mode [D)efault, N)one, S)et (default DEFAULT)]: DEFAULT

GPIB interface chip is Turbo-488 and NAT4882.

GPIB transfer mode is (default DMA): DMA

Refer to the GPIB-VXI/C User Manual for a descriptions of these settings.

1. For the GPIB mode, press "Enter" to leave the secondary addressing as the default.
2. The second prompt will ask you for a mask of GPIB addresses to avoid. This is useful if using only primary addresses and you have other instruments configured for some GPIB addresses. Obviously, you will want to avoid setting the GPIB-VXI/C to these addresses if other instruments are already using these GPIB addresses. Press enter to NOT avoid any GPIB addresses.
3. The third prompt is the new GPIB address of the GPIB-VXI/C. This example changes the GPIB-VXI/C’s primary GPIB address to 2.
4. Press enter on the last three options to use their default settings.

<<Press A Key to Return to Main Menu>>

Press any key to continue.

This will bring up the GPIB-VXI Nonvolatile Configuration Editor.
