WC/DC drives

Setting the SCSI ID jumpers

The SCSI ID for “WC” and “DC” model drives is normally set over the SCSI bus by the host system using connector contacts 39 (ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Users need not install jumpers to select SCSI ID.

Terminating the drive

“WC” and “DC” model dr ives do not have internal terminators or any other way of adding internal termination to the drive. Exter- nal termination for these drives is normally supplied by the host equipment when termination is required.
