STD-GPIB for Windows
Chapter 2
Hardware Configuration and Installation
                                                                                                                                                   
This chapter contains instructions to help you configure and install your STD-GPIB.
Warning:
Electrostatic discharge can damage some components on your
STD -GPIB.  To avoid such damage in handling the module, touch the
antistatic plastic package to a metal part of your computer chassis before
removing the module from the package.
The STD-GPIB default settings are suitable for most STD/STD32 systems.  However, if
any of the following situations is true, you must reconfigure the hardware.
If the default settings conflict with another device in your system
If you need to install more than one STD-GPIB
If your system CPU board supports only 8-bit STD bus transfers
If you already have STD -GPIB modules installed in your system, you can run the GPIB
Information utility to determine how the modules are configured.  For more information
about the GPIB Information utility, refer to Chapter 4, Debugging Your Application , in
the  NI-488.2 User Manual for Windows.
Table 2-1 shows the default settings for the switches and jumpers on the STD-GPIB.

The jumper settings for any interrupt level depend on which computer you are using
(Ziatech or WinSystems), so the STD-GPIB is shipped with interrupts disabled.
However, the NI-488.2 software is configured to use IRQ11 by default and will not
function properly until you disable interrupts in the GPIB software configuration
utility.  Your hardware and software settings must match.
To modify the default settings of the STD-GPIB, refer to the  Configure the Hardware
section of this chapter.  If you do not need to reconfigure the STD-GPIB, refer to the
Install the Hardware  section.
