The SCA (Single Connector Attachment) interface combines the Data, Power, and SCSI ID connectors into a single 80-pin connector. For these SCA drives to be used in a standard system or subsystem enclosure requires an adapter to convert the 80-pin connector back into separate Data, Power, and SCSI ID connectors. With SCA Adapters from Cables To Go, you can make this conversion with ease. The SCSI-3 to SCSI-3 adapter is designed to adapt an existing 68-pin ribbon cable to a SCSI-3 SCA80-pin connection. The SCA80 adapter includes an onboard power connection and termination/id jumpers.
