1.0 Introduction

The help file included with the HP 836XX Universal 
Instrument Driver contains instrument and programming 
information. This readme file contains additional
information concerning the driver.

The HP 836XX Windows 95 and Windows NT drivers are 
actually a single 32-bit driver. All of the directory 
paths which follow assume Windows 95. For Windows NT, 
change references from win95 to winnt. 

This HP 836XX driver conforms to all portions of the 
VXIplug&play driver standard which are applicable to 
conventional HP-IB. Two elements of the standard do not 
apply to the HP 836XX since it is not a VXI instrument. 
First, there is no soft front panel, as the HP 836XX can be 
controlled from its hardware front panel. Second, there 
is no knowledge base file, which is primarily a description 
of a VXI board.

This driver features:

1. Conformance with the VXIplug&play standard. The 
only exceptions are that it does not have a soft 
front panel or a knowledge base file.

2. It is built on top of, and uses the services provided 
by VISA. VISA supports GP-IB and VXI protocols. The 
driver can be used with any GP-IB card for which the 
manufacturer has provided a VISA DLL.

3. It includes a "Function Panel" (.fp) file which allows 
it to be used with visual programming environments 
such as HP-VEE, LabWindows, and LabVIEW.

4. It includes a comprehensive on-line help file which 
complements the instrument manual. The help file 
presents application programming examples, a 
cross-reference between instrument commands and 
driver functions, and detailed documentation of each 
function, with examples.

5. Source is included so that the driver can be modified 
if desired. The source conforms to VXI Plug & Play 
standards. Modifications should only be done by 
people who are familiar with the VXIplug&play 
standard.

6. It includes a Visual Basic include file (.bas) which 
contains the function calls in Visual Basic syntax, so 
that driver functions can be called from Visual Basic. 
If you use Visual Basic with this driver, you should be 
familiar with C/C++ function declarations. In particular, 
care must be taken when working with C/C++ pointers.

2.0 VISA Specific Information

The following topics refer to instances when the driver is 
used with different versions of VISA.

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 "GPIB0::19" instead of "gpib0::19"

2.2 Language Specific Features

Language Specific features are not supported with this 
driver.

-----------------------------------------------------------------------

3.0 Using the HP 836XX UID in Application Development Environments 

For general instructions on using the driver with HP VEE, 
Microsoft Visual C++, Borland C++, Microsoft Visual Basic, 
LabVIEW, and LabWindows/CVI, see the online help file.

Additional notes:

3.1 Microsoft Visual C++ 4.0 (& higher) and 
Borland C++ 4.5 (& higher)

1. The driver uses Pascal calling conventions.
2. Do not build the driver in the directory in which 
it was installed.

3.2 Microsoft Visual Basic 4.0 (& higher) 

Refer to the Microsoft Visual BASIC manual for additional 
information on calling DLLs.

3.3 LabWindows CVI/(R) 4.0 (& higher)

The HP 836XX driver is supplied as both a source code file 
and as a dynamic link library file (dll). There are 
several advantages to using the dll form of the driver. 
These include:

1. Transportability across different computer 
platforms
2. A higher level of support from Hewlett-Packard for 
the compiled driver
3. Faster load time for your project

Labwindows/CVI (R) by default will attempt to load the 
source version of the instrument driver. To load the dll 
you must include the file hp836xx.fp in your project. 
This file can be found in vxipnpwin95hp836xx. Do not 
include hp836xx.c in your project. You must also provide 
an include path for hp836xx.h. This is done by adding 
vxipnpwin95include to the include paths (CVI Project 
Option menu).
