Select an open PCI slot and remove the slot cover at the back of the PC. The CAN module can be inserted into every PCI slot. Insert the CAN-PCI/402 board into the selected PCI slot. Carefully push the board down until it snaps into place. - Page 19 (X610). You will find a figure showing the connectors on page 14. CAN-PCI/402-4/2Slot: If you are installing a CAN-PCI/402-4/2Slot with adapter board, you have to connect the third CAN interface (CAN2) via the lower DSUB connector (X400) of the adapter board and the fourth CAN interface (CAN3) via the upper DSUB connector (X410) of the adapter board (see figure 5, page 15).

Page 24: Message-Signalled Interrupt Handling
Technical Data 6.5 Message-Signalled Interrupt Handling The CAN-PCI/402 supports MSI. The equipped PCI-to-PCIe bridge is able to convert MSI's from the PCIe bus to “Hardware” Interrupt lines or to PCI MSI'. The MSI enable bit in the capability pointer of the PCI-to-PCIe bridge is enabled. Usually this bit is modified during the plug-and-play run of the operating system and is set depending on the system configuration: Therefore it is not possible to affect the usage of MSI/Legacy IRQ directly. -
