Abstract

In complex systems which involve a large amount of interacting electronic equipment and interconnecting cabling, the maintenance and testing required to isolate defective components or components having degraded performance become an almost continuous task. The system of this invention includes new techniques for continuous testing of components and interconnecting cabling of such a complex system such that deteriorating performance can be flagged thereby substantially eliminating catastrophic type system failure without at the same time requiring additional components and interconnecting cabling. This invention is potentially suitable for operation with a data transmission system which includes a master controller for converting parallel digital data from a computer to serial digital data for transmission to the using device through a single communication path where it is then converted to a form suitable for the using device. Such a data transmission system would also include peripheral control devices for converting data received in various forms from the using devices into serial digital format for transmission to the master controller where it is then converted to a form suitable for the computer.
