HELP
Selects an I/O object to control any
configured instrument or adds a new
instrument to the list of configured
instruments.  This feature is available in HP
VEE-Test only.

USE
Click on I/O ==> Instrument and examine the
list of configured instruments in the Select
an I/O Device dialog box.

If the instrument you want is not properly
configured, go to Configure I/O and configure
it.  If the instrument you want is in the
list and is properly configured, follow these
instructions:

1.  Click once on the desired instrument
to highlight it.

2.  Click one of the buttons at the bottom
of the dialog box to select the type of
object you wish to use to control the
instrument.  If you are not sure which type
of object to use to control the selected
instrument, try State Driver.

If the instrument you want is not in the
list or is not properly configured:

1.  Click on Add to add a new instrument.

2.  Complete the resulting dialog boxes.
Refer to the Configure I/O entry for details
about how to complete these dialog boxes.

LOCATION
I/O ==> Instrument

NOTES
All instruments should be configured before
they can be opened by way of the Instruments
menu selection.  The best way to configure
instruments is to use the Configure I/O menu
selection.

Note that an I/O object may be operated
with or without actual instruments connected
to the computer.  If you wish to control a
live instrument, you must set a correct,
non-zero address and enable Live Mode.  The
address and Live Mode setting are controlled
by way of the I/O ==> Configure I/O menu
selection.  If the address is zero or if Live
Mode is off, the instrument object operates
but does not attempt to communicate with a
physical instrument.

State drivers can be used interactively or
within a model.  To set the value of an
individual component, click on the field
containing the value of the component and
complete the resulting dialog box.  To make a
measurement and display the result, click on
the corresponding numeric readout or XY
display inside the State Driver open view.

It is possible to have more than one
object controlling a single instrument.  It
is also possible to have multiple copies of
the same driver, each controlling a different
physical instrument.  In either case, it is
the configured name that determines which
object controls which instrument.

Your system administrator must properly
configure your computer before it is possible
to communicate between HP VEE and any
hardware interface.  If you believe that you
have properly followed all HP VEE procedures
properly and you still cannot achieve any
level of communication with an instrument,
the problem may be with your computer
configuration.  Ask your system administrator
to read this explanation and verify proper
configuration of your system's interface
drivers.  (These interface drivers are
different from the instrument driver files
included with HP VEE).
