PEX8IX is a PCI Express X8 Bus Isolation Extender that allows user to test the PCI add-on boards quickly without having to power the system down each time. It is especially designed to save valuable labor and time in production testing environment. It is also a great tool for engineers during product development while many changes and testing are required. It provides total power and signal isolation between the motherboard and the board under test. It can be controlled manually by an on-board toggle switch or by external TTL signals. Besides saving time for testing, it also protects the motherboard from damages that can be caused by bad I/O boards under test. The PEX8IX is designed with many years of field experience and real user suggested features. It is built with quality materials and state of the art components. The PEX8IX is made in USA with 90 day warranty.
