Drive Addressing and Interface Termination
ID0, ID1, ID2 SCSI Address Jumpers
The SCSI ID (drive address) jumpers are identified as ID0, ID1, and ID2.
ID selection is binary, as shown in the table below.
For multiple drive installations, on one Host Adapter, each drive must
have a unique address. Drives are configured as SCSI ID 0 at the factory.
RN9 Interface Terminator
The Interface Terminator factory installed at RN9 provides proper termination
for the interface lines. When daisy-chaining multiple drives, leave the terminator
installed only in the last physical drive (or drives) on the daisy chain cable;
remove the terminator from each of the other drives (or the host computer).
W1, W2 Terminator Option
W1 and W2 select the source of terminator power (+5V) for the interface terminator.
If a jumper is installed at W1 and no jumper is installed at W2 (the factory default
configuration), the drive provides terminator power. This configuration is used for
PC/AT applications. If no jumper is installed at W1 but a jumper is installed at W2,
terminator power must provided by the host computer system via interface connector
J1, pin 26.
W3, Spindle Option
W3 selects the spindle control option. If W3 is installed, the drive waits for a Start
Spindle command after power is applied to start the spindle motor. If W3 is not
installed (the factory default configuration), the drive automatically starts the spindle
motor at power-on. W3 is not installed for PC/AT installations.
W9 Bus Parity Option
W9 selects the parity check option. If W9 is installed, the drive neither generates nor
detects parity. If W9 is not installed (the factory default configuration), the drive generates
parity and enables parity detection. W9 is usually not installed for PC/AT applications.
Verify the correct configuration required by your Host Adapter.
