¶The connectors are of the shielded type.

¶For details on the control commands, refer to the separate specifications manual.

2) Electrical specifications of SCSI

Output	The signals driven by SCSI equipment
characteristics	present the following output characteristics.
	True (LOW): VOL = 0.0 to 0.4 V DC
	IOL = 48 mA (0.5 V DC) max.
	False (HIGH): VOH = 2.5 to 5.25 V DC
Input	The signals driven by SCSI equipment present
characteristics	the following input characteristics.
	True (LOW): VOL = 0.0 to 0.4 V DC
	IOL = -0.4 mA (0.4 V DC) max.
	False (HIGH): VOH = 2.0 to 5.25 V DC

NOTES:

¶As the SCSI interface is of the single-ended type, it should be terminated on both ends of the cable.

¶The maximum recommended length of an SCSI cable is 6 meters (20 feet) (including internal wiring).
