1 Introduction
The PCIe-PXIe- 68638 PCI Express to PXI Express extension kit
pro-vides control of PXI Express modules installed in a PXIe
chassis using high bandwidth PCI Express technology. The
extension kit provides up to 4GB/s bandwidth using PCIe x8 Gen2
signaling. With comprehensive hardware and software
transparency, the extension kit enables fast and convenient
detection of any PXI modules installed in the system, requiring
no additional drivers or software.
The host PC may be separated from the PXI Express chassis by
up to five meters using high-quality shielded twisted copper
cables. The robust and reliable PCIe to PXIe Extension Kit is
suited for test and measurement applications with high-density I/O
requirements and can be used in hazardous industrial control and
automation environments.
The dual port PXIe-
68638D provides the capability of multi-
chassis control in a daisy chain configuration with the upper port
connected to a PCIe- 68638 installed in a host PC, or
PXIe- 68638D /PXIe- 68638P in a PXI Express chassis,
and the lower port connected to another PXIe- 68638
or PXIe- 68638D in subsequent chassis.
The PXIe- 68638P supports multi-chassis expansion in a daisy
or star chain configuration. A PXIe- 68638P in a peripheral slot
can connect to another chassis with a PXIe- 68638
or PXIe- 68638D to establish multi-chassis control.
1.1 Controlling a PXI Express System via PCI
Express
Based on PCI Express technology, the PCIe to PXIe Extension Kit
provides bus extension capability through a high-speed differential
signal interface.
The PCIe-PXIe-
68638 PCI Express-to-PXI Express expansion
kit provides additional PXI instrument slots to the host computer
by implementing PCI Express-based control of PXI modules.
The technology consists of a PCIe- 68638 host adapter installed
in the host computer, a PCIe x8 cable, and a PXIe- 68638 remote
controller with the 3U (Eurocard) expansion module. The
PCIe- 68638 comes with a PCI Express x8 interface and a PCIe x8
cable connector.
