DSP2022-S SCSI Disk Drive Installation Guide
Set the SCSI Address Remotely
When jumpers 0, 1, and 2 are left in place for a device
address of 0, the drive will use the remote active encoded
SCSI device address (ID) number on the vendor-specific
connector at the rear of the drive. If there is not an active
ID address on pins A5–A7, the drive will assume the ID is
0. Refer to Table 5 for the pin electrical states.
