Hardware and Software Configuration Appendix CGPIB-PCII/IIA for Graphics C-16 © National Instruments Corp.If you change the interrupt jumper setting from the default setting, record thenew setting on the GPIB-PCII/IIA Hardware and Software Configuration Formin Appendix E, Customer Communication. Remember that you must run theIBDIAG diagnostic program and configure the software, as explained later inthis appendix, after you change any hardware configuration settings.Possible ConflictsTable C-4 lists some of the interrupt lines used by other PC plug-in interfaceboards and adapters. This is by no means a complete list, but it may help indetermining possible interrupt conflicts. Symptoms of interrupt conflicts varywidely. Conflicts can prevent the computer from booting. They may also causerepeated time outs on GPIB function calls. When conflicts do surface, theproblems can exhibit themselves simply as strange behavior.National Instruments has made every effort to select a default interrupt line thatwill work. However, because of the numerous different interface boardsavailable for use in the PC, it is not possible to select an interrupt line that isguaranteed to work in all systems. Therefore, be certain of your system’sinterrupt assignments before proceeding with installation.Table C-4.
