PEX16IX, PCI EXPRESS X16 Bus Isolation Extender Specification

PEX16IX is a PCI Express X16 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 PEX16IX 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 PEX16IX is made in USA.

Product Features:

• Total power and signal isolation.
