# Introduction

The PCIe-PXIe-8638 PCI Express-to-PXI Express expansion kit provides control of PXI Express modules installed in a PXI Express chassis using high bandwidth PCI Express technology. The extension kit can provide up to 4GB/s using PCIe Gen 2 x8 signaling.

The PCIe-PXIe-8638 PCI Express-to-PXI Express expansion kit provides additional PXI instruments slots to the host computer by implementing a PCI Express-based control of PXI modules. The technology consists of a PCIe-8638 host adapter installed in the host computer, a PCIe x8 cable, and a PXIe-8638, a remote controller with the 3U (Eurocard) expansion module. The PCIe-8638 comes in a PCI Express x8 footprint and equips with PCIe x8 cable connector.

PXIe-8638D with dual ports provides capability of multi-chassis control as a daisy-chain configured. The upper port would be connected to a PCIe-8638 which be installed in a host PC. And the lower port would be connected to another PXIe-8638 or PXIe-8638D in subsequent chassis.

PXIe-8638P also is another option on multi-chassis expansion as a daisy-chain or star-chain configured for user only having PXIe-8638 at first place. with PXIe-8638P in a perapheral slot, it can connect to another chassis with PXIe-8638 or PXIe-8638D to establish multichassis control.

With comprehensive hardware and software transparency, the expansion kit enables fast and convenient detection of any PXI cards installed in the system, requiring no additional drivers or software.
