NI-488.2 calls. Use

an interface handle, or the 
set 488.2
 command to switch to a 
488.2 prompt. 
The following example uses 
ibdev
 to open a device, assigns it to 
access interface 
gpib0
, chooses a primary address of 6 with no 
secondary address, sets a timeout of 10 seconds, enables the END 
message, and disables the EOS mode:
:ibdev

If you type a command and no parameters, Interactive Control prompts you for the 
necessary arguments. If you already know the required arguments, you can type them at 
the command prompt, as follows:

Note
If you do not know the primary and secondary address of your GPIB instrument, 
right-click on your GPIB interface in Measurement & Automation Explorer and select 
Scan for Instruments. After Explorer scans your interface, it displays your instrument 
address in the right window pane. The instrument shown in Figure 6-1 has a primary 
address of 
1
 and no secondary address.
