Functional Unit Descriptions
PCI Express x1 Card Edge Connector
The card edge connector allows you to use the NI PCIe-8360 in a x1 or
wider PCI Express slot in a PC. The PCI Express Card Electromechanical
Specification defines this connector.
PCI Express x1 Switch
The PCI Express Base Specification defines a PCI Express switch as a
logical collection of PCI Express-to-PCI Express bridge devices. On the
NI PCIe-8360, the upstream port of the switch is connected to the
PCI Express x1 card edge connector, and the two downstream ports are
connected to the two cabled PCI Express connectors.
Cabled PCI Express Connector
The cabled PCI Express connector provides all necessary signals to connect
an NI PCIe-8360 and an NI PXI-8360. These signals include the
PCI Express transmit and receive pair, the system clock, and a presence
detect signal.
