1. Introduction
The help file included with the HP E1459 VXIplug&play driver contains
instrument and programming information. This readme file contains
additional information for the HP VXIplug&play programmer.
- ---------------------------------------------------------------------------
2. VTL/VISA Specific Information
The following topics refer to instances when the driver is used with
different versions of VTL.
2.1 Instrument Addresses
When using HP VXIplug&play instrument drivers, instrument addresses must
be all uppercase letters. Implementation of the addressing scheme is
vendor specific and some vendors support mixed cases. However, for
maximum portability, the instrument address should use uppercase
characters only.
For example: use "VXI0::56::INSTR" instead of "vxi0::56::instr"
2.2 Executing the Soft Front Panel without VTL/VISA
The VTL/VISA dynamic link library provides a communication library
between your program and the instrument. The SFP may be executed without
VISA or without the HPE1459_32.dll present. It will do a partial emulation
of the hardware for demo purposes.

3. Using the HP E1459 Driver in Application Development Environments
This section offers suggestions on using the hpe1459_32.dll within
various application development environments.
3.1 C/C++
Refer to your C/C++ manuals for information on linking
and calling .DLLs.
Rebuilding the driver DLL should be done in a different directory than
the one the driver was installed in order to differentiate the changes.
3.2 Microsoft Visual Basic
Refer to the Microsoft Visual BASIC manual for information on calling DLLs.
The BASIC include file is hpe1459.bas, which is contained in the directory
~vxipnpwinXXinclude. The ~ refers to the directory in the VXIPNP variable.
By default this is set to C:. winXX refers to the operating system -- win95
or winNT.
4.0 Known Defects
This driver does not work on National MXI 1 interface.
This card did not work with the HP E1406 command module. (It can
miss interrupts). This problem occurred with HP I/O Libraries version
F.01.02. Please upgrade your system if you are using that version.
