1. Introduction
The help file included with the E1328A VXIplug&play driver contains
instrument and programming information. This readme file contains
additional information for the 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 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 Using Callbacks and Soft Front Panel Timeouts
Callbacks are not supported on win32.
2.3 Executing the Soft Front Panel without VTL/VISA
The VTL/VISA dynamic link library provides a communication library
between your program and the instrument. If you receive a message
that VISA.DLL cannot be found when executing the soft front panel
(hpe1328.exe), VTL/VISA is not installed on your system. To
communicate with the E1328A, you must install VTL/VISA from discs
supplied with your computer or I/O card. However, it is still
possible to execute the soft front panel in a demonstration mode
without VTL/VISA and/or the E1328A. Simply press 'ok' when the
dialog box appears and the soft front panel will then become
available.

3. Using the E1328A Driver in Application Development Environments
This section offers suggestions on using the hpe1328.dll within
various application development environments.
3.1 C/C++
Refer to your C/C++ manuals for information on linking
and calling .DLLs.
3.3 Microsoft Visual Basic
Refer to the Microsoft Visual BASIC manual for information on calling DLLs.
The BASIC include file is hpe1328.bas, which is contained in the directory
~vxipnpwinXXinclude. The ~ refers to the directory in the VXIPNP variable.
By default this is set to C:. XX refers to 95 or NT, depending upon your
operating system.
