ABSTRACT:
The present invention includes a multi-mode SCSI backplane and a detection logic that is used in conjunction with the backplane. In this invention, the SCSI backplane can be configured in different modes, included simplex mode and duplex mode. The detection logic can also detect when an illegal configuration is connected to the SCSI backplane and indicate the presence of the illegal configuration by triggering a light emitting diode (LED) or some other indicating mechanism. The detection logic is implemented with a handful of cost-effective field effect transistors (FETs), resistors and LEDs and no additional IC logic gates or Programmable Array Logic (PAL) is necessary.
