Auto Sense™ is a unique feature on Paralan SCSI products. The 5 V line may need to supply power to terminators on the other end of the SCSI cable. If 5 Volts is not on the line, Paralan SCSI Expanders (Extenders, Converters and RegeneratoR™s) will automatically place 5 V on the bus. If the 5 V is grounded (due to inverted cable or incorrect wiring, for example) the expander will automatically shut off 5 V power to the bus, without blowing a fuse or affecting the operation of the expander. Auto Sense™ solves many initial SCSI installation problems.
