This document is provided as a supplement to the documentation included on the National Instruments CD. This document specifically addresses the installation and configuration of the PCI-GPIB card to operate with Princeton Applied Research hardware and their supporting software in a Windows®
95/98 operating system.
Included with the National Instruments PCI-GPIB card is an instruction sheet titled "Getting Started". Follow the instructions on this sheet for GPIB software and card installation. Step 4 of this document discusses the "Getting Started Wizard" that allows you to "Verify your software and hardware installation", and to test communications with the attached hardware (i.e. the potentiostat). Provided the NI card and software were properly installed, a "passed" status depicts the outcome of a successful installation. If everything passed, click Exit to continue. Any failed steps in the verification process should be addressed with the National Instruments documentation on their CD or contact National Instruments Tech Support at www.ni.com
for troubleshooting tips.
The next step in the verification process is to "Communicate with your instrument". NOTE!
Due to differences in program communications between National Instruments and Princeton Applied Research, this may give false information. At this point, it is best to check the box "Do not show at Windows startup" and click the "Exit" button to exit the Getting Started Wizard.
PCI-GPIB Card Configuration for Windows® 95 and 98
Once the National Instruments GPIB card and drivers have been installed, you may proceed to the configuration of the GPIB driver to run optimally with the Princeton Applied Research systems. For Win 95/98 systems, the National Instruments driver properties are located within the Device Manager.
Go to Start > Settings > Control Panel > System
and click on the Device Manager
tab. Once there, you need to select the National Instruments GPIB Interface
line such that it is highlighted blue. After highlighting, click the Properties
button in the lower left of the System Properties
window. This will bring up the National Instruments Interface Properties
window which has two separate pages.
page contains a box that needs to be checked in order to run any DOS applications under Win 95/98. (Note: your DOS software will not run if this box is unchecked. Also, ensure that your Config.sys file no longer contains the ?Device=C:/pathname/GPIB.COM? command; this will conflict with the new Windows driver.)
Next, enter the Device Templates
window. Device Name attributes need to be changed such that the Readdress
box is checked for each device connected to the GPIB card (DEV14 is the factory default GPIB address setting in our systems; if using multiple systems each must have a different setting). Note: GPIB0 is the card ID in the system. This should remain GPIB0 unless you have multiple GPIB cards in the same PC. After making these changes, click OK
to return to the Device Manager.
Back at the Device Manager, highlight the PCI-GPIB line and click the Properties button, which brings up the PCI-GPIB Properties
On the PCI-GPIB Properties window, click on the NI-488.2 Settings
tab. In this section, ensure that the Interface Name is GPIB0. Next, click the Advanced
.. button in the lower right of the window.
Once on the Advanced NI-488.2 Settings
window, change the Bus Timing
to 2 µsec
, disable the Automatic Serial Polling
, and enable Assert REN when SC
. After making these changes, click the OK button, then click OK again to go back to the PCI-GPIB Properties
Finally, click the Resources
tab and verify that an Interrupt Request and two Memory Ranges have been assigned to the card. Also, verify that the bottom of the screen reads "No Conflicts".
This completes the installation and configuration of the National Instruments PCI-GPIB card and you may now exit the Device Manager, reboot the computer, and proceed with the installation of the Princeton Applied Research Software.
