ISAIX16, ISA Bus Isolation Extender Specification

ISAIX16 is an ISA Bus Isolation Extender that allows user to test the ISA add-on boards quickly without having to power the system down each time. It is especially designed to save valuable time and labor 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. The ISAIX16 is designed with many years of field experience and real user suggested features. It is built with quality and state of the art components. The ISAIX16 is made in USA with one year warranty.
