Chapter 4 Installation Verification and Troubleshooting
© National Instruments Corp. 4-5 GPIB-ENET for Macintosh
My driver is not communicating with the GPIB-ENET. What should I do?
Make sure that DIP Switch 7 is set to OFF. If Switch 7 is OFF and the driver still cannot
communicate with the GPIB-ENET, make sure that the Ethernet Port Configuration slide
switch is in the correct position for your network connections.
My I/O worked with a board interface, but it times out when I use the GPIB-ENET
interface. What should I do?
Network communication is slower than straight cable communication. You might need
to raise the Timeout value on your NI-488 Config configuration screen.
The Update utility returns the message "Bad checksum." What should I do?
Run the Update utility again. Your imagefile might be corrupted. If the same message
appears when you run the utility again, try reinstalling your NI-488.2 software and then
running the Update utility again.
I powered off my GPIB-ENET before recording the flashing READY LED pattern.
What should I do?
Try to duplicate the error before calling National Instruments for assistance. Recording
the READY LED pattern is not critical to the operation of your GPIB-ENET, but it saves
you time and helps Product Support to diagnose the problem more quickly and
accurately.
What do I do if I have installed the NI-488.2 software and now my Macintosh
crashes upon startup?
Try changing the name of the NI-488 INIT to ZNI-488 INIT. Because INITs load
in alphabetical order, the ZNI-488 INIT will load last, preventing possible corruption
from INITs that load after it. If changing the name of the NI-488 INIT does not solve
the problem, another INIT file might have a conflict with the NI-488 INIT. Try
removing some of your other INIT files. You can store them in a temporary folder, in
case you need to reload them later. If you are using System 7.5 or later, you can use the
Extensions Manager control panel to disable certain extensions and control panels.
My system has been crashing since I switched to a Quadra computer. What should
I do?
This problem was associated with some versions of the NB Handler INIT. Upgrade
to the NI-488 INIT to resolve this situation.
