3. 1. 4 SCSI 68 pin Connector
Figure 3-2 illustrates SCSI 68 pin connector, and table 3-1 shows the assignments for the pins of the connector.
Figure 3-2: Non-shielded SCSI Device Connector
SDT-11000 supports Low-Voltage-Differential SCSI configuration as shown table 3-1. SDT-10000 and SDT-11000
support Single-Ended SCSI configuration as shown table 3-2. SDT-11000 detects and switches SCSI configuration
between Low-Voltage-Differential and Signal-ended modes by monitoring DIFSENS signal assigned pin 16 SCSI bus.
