If Data Transfers to Devices Fail
If devices attached to your ISA (82341) GPIB card are detected, but data transfers to those devices fail, this is usually caused either by an IRQ conflict with another card or by your system having no IRQs available for this card. If no IRQs are available, the IRQ value shown in Connection Expert will be - 1.
For Windows XP/Vista/7: Try changing the IRQ setting to other values. You must reboot after changing the value to test it. If none work, you will have to free up other IRQs by disabling devices such as serial ports or sound cards.
If Connection Expert Finds 82350 Card with Serial
Number ffffffff
If Connection Expert reports finding an 82350 card with serial number ffffffff, it is typically caused by the PCIe card are not properly configured. Try the following:
1Check BIOS Setting. For Windows NT, make sure the BIOS Operating System setting is set to Not PnP OS or to Running Windows NT or to
Other.
2Upgrade your system BIOS to the latest version. Note that even new computers often have newer BIOSs available.
3If your computer locks up or freezes after installing. Typically, this is caused by interrupt conflicts with other drivers in the system. PCI allows sharing of IRQs, but this also means that the drivers for cards with which the 82350 shares an IRQ must handle interrupt chaining properly. Both NT and Windows 98 allow multiple drivers to install interrupt service routines (ISRs) for a single IRQ. The operating system will keep a list of all the ISRs installed for each IRQ. When the IRQ is asserted, the operating system will call each ISR in turn until
