1. Introduction
The help file included with the HP E1330 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::144::INSTR" instead of "vxi0::144::instr"
2.2 Read Status Byte
Hewlett-Packard VTL Revision 1.0.0 has a defect with viReadSTB() when
using VXLink, the EPC-7, or the EPC-8. A patched version of visa.dll is
available which resolves this.
The visa.dll version in HP VTL Revision 1.0.0 should have an installed
date of May 2, 1995, is 110,112 bytes, and is revision 1.1.0. The patched
visa.dll is revision 1.1.1.
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. The SFP may be executed without
VISA or without the HPE1330.dll present. It will do a partial emulation
of the hardware for demo purposes.

3. Using the HP E1330 Driver in Application Development Environments
This section offers suggestions on using the hpe1330.dll within
various application development environments.
3.1 Microsoft Visual C/C++
The file hpe1330.mak included in this release is an EXTERNAL makefile
for use with Microsoft Visual C/C++. To use it, send the command
"nmake -f hpe1330.mak".
Refer to your Microsoft Visual C/C++ manuals for information on linking
and calling .DLLs.
A.) Programs should be compiled and linked using the large memory model.
B.) The driver uses Pascal calling conventions.
C.) 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 Borland C/C++
Refer to your Borland C/C++ manuals for information on linking and
calling .DLLs.
A.) Programs should be compiled and linked using the large memory model.
B.) The driver uses Pascal calling conventions.
C.) Rebuilding the driver DLL should be done in a different directory than
the one the driver was installed in order to differentiate the changes.
3.3 Microsoft Visual Basic
Refer to the Microsoft Visual BASIC manual for information on calling DLLs.
The BASIC include file is hpe1330.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.
