SDX-800V supports both Low-Voltage-Differential SCSI configuration as shown table 3-4 and Single-Ended SCSI
configuration as shown table 3-5. SDX-800V detects and switches SCSI configuration between
Low-Voltage-Differential and single-ended modes by monitoring DIFFSENS signal assigned pin 16 in SCSI bus.
