SINGLE-CONNECT ADAPTER BOARD

The StorCase® Technology Single-Connect Adapter Board (P/N DX100-SWC) allows the connection between a 68-pin Wide SCSI cable connector and a storage device which has a Single-Connect (80-pin) type interface connector. The DX100-SWC also supports Ultra2 and Ultra160 (LVD) and Single-Ended (S.E.) interfaces.

The Single Connect Adapter Board provides a standard 4-pin DC power connector, and several jumper options as described below (refer to the device manufacturer's instructions for specific jumper setting information).

Jumpers on the Single-Connect Adapter Board are factory-installed on the Enable Termination Power (TPR) pins, and on all of the SCSI ID Select (ID0-ID3) pins. These jumpers may be reconfigured as required. Refer to the following information for pin descriptions.

Table 1: Motor Start Controls

Activity LED Out Signal

The Activity LED Out Signal, provided by the drive, is intended to support a drive activity LED. This signal is designed to pull down the cathode of the activity LED indicator during periods while the drive is forming SCSI operations.

Spindle SYNC

The Spindle SYNC signal is provided for spindle synchronization between multiple drives. Synchronized drives should be of the same or equivalent model types. (Synchronization protocol and the electronic requirements for the SYNC signal are defined within the drive specifications. Spindle synchronization is managed by the SCSI command set).

The Single-Connect Adapter Board provides 2 sets of Spindle SYNC pins. To implement this option, a jumper wire must be run from the SYNC pin on the Adapter Board to a SYNC pin on another drive or Adapter Board. This signal may be jumpered in a daisy-chain configuration for up to 15 drives.

SCSI ID Select

Each device on the SCSI bus must have a unique SCSI ID number. The SCSI ID Select pins allow the selection of an appropriate SCSI ID (0-15 for 16-bit connections).
