been removed, the NI-488.2 software indicates a Non-Existent Board
Error (ENEB). For information about GPIB error codes, refer to the
NI-488.2 User Manual for MacOS.
If you remove a PCMCIA-GPIB card and then reinsert it while an
application is using its GPIB board, the GPIB board loses its state
information and the ENEB error is reported. To use the GPIB board
again, you must place the GPIB board back online by using
ibfind
or
ibonl
with a parameter of 1. As a general rule, you must place the
GPIB board offline before removing its PCMCIA-GPIB card by calling
ibonl
with a parameter of 0.
How can I configure more than two PCMCIA-GPIB cards?
If you want to use more than two PC Card Sockets by adding a PC Card
expansion module, you can configure the additional socket by selecting
the PC Cards expansion sockets interface menu.
What do I do if I try to eject the PCMCIA-GPIB, but it won’t eject?
Make sure the card is offline by issuing an
ibonl(0)
call to the card.
The card will not eject while online. Also, make sure the card is not
stuck in the socket. Sometimes an improperly seated PC Card will fail
to eject.
What do I do if my card does not work correctly with a scanner or
film recorder?
Try checking the Unaddressing option in the
NI-488 Config
control
panel.
