Continues to monitor the Diffsens signal. If | Maxtor 10K III

Feature Descriptions

&+((5'05The DIFFSENS signal in the SCSI bus defines the current operating mode of the SCSI bus. A level below +.5 volts defines a single-ended bus. A level between +.7 and +1.9 volts defines an LVD bus. A level above +2.4 volts defines a High Voltage Differential (HVD) bus. Before LVD was introduced, HVD was simply called Differential SCSI.

All single-ended-only devices connect the DIFFSENS signal to ground. On an LVD bus, the terminators drive the DIFFSENS signal to +1.3 volts unless some device is holding the signal at ground. HVD devices pull DIFFSENS up to +5 volts via a resistor.

The Maxtor Atlas 10K III disk drive is designed with a circuit that monitors the level of DIFFSENS at power-on. The drive then enables the appropriate circuits for LVD or single-ended operation, or disables its interface completely if it detects an HVD level on DIFFSENS.

The two normal operating environments for the Maxtor Atlas 10K III disk drive are an all-LVD or (LVD/MSE) bus, in which case it operates in its LVD mode, or a bus that contains at least one single-ended device, in which case the Maxtor Atlas 10K III disk drive operates in single-ended mode.

HVD mode is not supported by the Maxtor Atlas 10K III disk drive. Signal levels on an HVD bus can reach as high as +15 volts due to allowed common mode transients.
