SCSI cable

All SCSI devices on one bus are daisy-chained with an SCSI cable.  A terminating resistor
must be mounted in the SCSI device at each end of the SCSI cable.

Because an SCSI terminating resistor module has been mounted in the IDD of single-ended
type SCSI at factory shipment, it must be set to not-connection when the IDD is not connected
at either end of the SCSI cable.  See Section 5.3 for details.

The maximum number of SCSI devices that can be connected to the SCSI bus is 16 for the 16-
bit SCSI, including the host adapter, IDD, and other SCSI equipment.

For the 16-bit SCSI, the connector for the SCSI cable must be an unshielded 68-contact socket
having 34-contact rows spaced 1.27 mm (0.05 inch) apart.  (See Figure 4.26.)
