If you select the ibaN-2E interface, you will see the properties of the card in several tabs on the right-hand side of the dialog. Select the Configuration tab.

Interrupt mode

The interrupt mode is set automatically by ibaPDA: As soon as several different cards are inserted, Master mode internal is set.

Only if no other card types but several ibaN-2E cards are inserted, you can specify which of the cards has the Master mode internal and thus generates the interrupt for the other cards. The interrupt is passed to the other iba PCIe cards (interrupt slaves) via the synchronization line (ribbon cable supplied).

In use

Enable the option if you want to use the card with ibaPDA.
