The classes and subclasses in the tree are described here.
• The Open/Close function panels open and close GPIB boards and devices.
• The Configuration function panels alter configuration parameters that were set during
installation of the GPIB handler or during the execution of previous program statements.
• The I/O function panels read and write data over the GPIB. These functions can be used at
either the board or the device level.
