摘要
The present invention relates to a failure diagnostic test signal generating method for a PC-based I / O card malfunction diagnosis system structure and the structure. The present invention is a diagnosis result display keyboard, and has a failure diagnostic information input-output unit 100 configured with a mouse, and separating the I / O card 200 and the failure backplanes of I / O cards to be diagnosed as a reference positionally , not the vendor lock-in by selection of the I / O card 200 serving as a reference to the signal type. In other words, I / O card to fault diagnosis by employing only the ISA bus or PCI bus failure can be diagnosed. And you need not be the same as the connector between the two I / O cards by using a plurality of connectors in a separate interface board between the I / O card to fault diagnosis with I / O card as a reference. Signal corresponding connection between these connectors were also facilitate the connection by using a jumper. Further operable with the I / O card and by inserting the display instrument board between the I / O card to diagnose the failure can be visually identified by the diagnostic operation of the card, automatic and manual modes the fault diagnosis mode in which the reference It makes. Also it takes the exclusive OR of the output signal generated by an adjacent channel to the failure determination of the cable connecting to the card when the card connector of the automatic fault diagnosis mode.
