This SCSI cable must have the proper connector for the SCSI external connector on one end, and the proper connector for the external device on the other end.

Serial port connectors Serial ports are used to communicate with printers, plotters, external modems, auxiliary terminals, and other computers. Your server provides two serial ports (1 and 2). You can add more serial ports by installing a serial adapter in one of the expansion slots. Serial ports transfer data asynchronously; they can transmit any number of bits at any time, with no restriction on the duration of the pauses between characters. The serial ports transmit and receive data and commands at a rate of 300 bits per second (bps) up to 115 200 bps. The bits-per-second measurement is commonly referred to as the baud rate. Chapter 4.
