3. Right-click on your GPIB interface and select Interactive Control
from the drop-down menu that appears.
For help on any Interactive Control command, type help followed by
the command. For example, type help ibdev or help set.
4. Open either an interface handle or device handle to use for further
NI-488.2 calls. Use ibdev to open a device handle, ibfind to open
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
enter board index: 0
enter primary address: 6
enter secondary address: 0
enter timeout: 13
enter ‘EOI on last byte’ flag: 1
enter end-of-string mode/byte: 0

Note 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:
:ibdev 0 6 0 13 1 0

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.
