The following application
note is intended to aid a first time user of the IEEE
icon in WorkBench PC for Windows (WBfW). In order for the
IEEE icon to operate correctly there are certain software
and hardware guidelines that must be followed. Please
check the following list to ensure that you are properly
set up to use this icon:
- An IEEE board must
be installed in the computer. This card must be
either an OMEGA OMB-PER-488 series or a National Instruments IEEE
- There must be a
DRVR488.DLL file in a /Windows/IEEE directory if
you are using an IOTech card; NI4882GP.GRP and
GPIB.ini files must be in the Windows directory
for National Instruments cards. There will also
be a GPIB-PCW directory for a National board.
- The following lines
must be present in the autoexec.bat file for
Set Path = C:\Windows\Ieee488; %PATH %
- The correct driver
must have been installed during the installation
of WBfW. There are two options: National
Instruments or IOTech IEEE driver. WBfW requires
that two drivers are installed for the IEEE icon
to function: the driver that comes with the IEEE
board and the WBfW driver that connects WBfW to
the IEEE driver (either iotech.dll or NI.dll).
- Each IEEE device
needs a seperate IEEE icon. Up to 15 devices can
be attached to one IEEE board.
- It is suggested that
the user build upon the default commands in the
Start menu item within the IEEE icon itself. It
may also be necessary to use Wait states in the
command structure in order for WBfW to wait long
enough for an instrument to respond.
For National Instrument
There are two diagnostic
tools that come with the NI IEEE board and that are
loaded into the Windows environment. These are
"Hardware Diagnostic" and "Software
Diagnostic." These two tools should be used at
installation to test for presence and operability of the
hardware and presence and correct installation of the NI
IEEE drivers, respectively.
If the above two tools
function correctly the next step should be to use a third
NI tool called "Interactive Control" which
operates much like a COM terminal panel. Chapter 5 of the
NI manual contains instructions on how to use this
If the above three
software tools operate correctly, and communication with
the device in question has been possible, then the
command structure used in "Interactive Control"
should be copied to the WBfW IEEE icon and communication
should be attempted form WBfW. There may be some
adjustment of syntax necessary.
