Intelligent or Manual SCSI Switching for your SCSI 1, SCSI 2 or SCSI 3 Devices

SCSI switches from Digital Controls make it possible to share one or two SCSI devices or strings of SCSI devices between two SCSI systems. Switching peripherals gives you low-cost backup and makes better use of expensive hardware such as tape drives.

SCSI switches from Digital Controls are compatible with single-ended, differential and even wide SCSI devices. They can be used to redeploy SCSI 1, SCSI 2, or SCSI 3, 8 or 16 bit devices. Switches can be configured in either a 2x1 switch (add the right terminator) or 2x2 configurations.

  • Ability to connect one or two SCSI hosts to one or two strings of SCSI peripherals
  • Compact, solid-state design
  • Ability to switch 8-bit Narrow or 16-bit Wide SCSI
  • Supports SCSI 1, SCSI 2 or SCSI 3
  • Supports Differential or Single-ended SCSI
  • Supports Fast SCSI
  • Bi-Color LED indicators display switch position
  • One-year warranty

Additional Features of the Intelligent SCSI Switch
    • Can be switched and locked via SCSI command from either host or via the serial port
    • Prevents the SCSI bus from being switched (manually or by either host) if there has been any activity on either SCSI bus within a selectable number of seconds
    • Performs self tests at power-up
    • Supports SCSI RESERVE and RELEASE commands for systems with a shared SCSI bus

Model 90020, operated manually, has front panel LEDs which indicate the active position. Models 90030-S (single-ended) and 90030-D (differential) are intelligent switches that feature host-controlled switching and a lockout feature to prevent unauthorized use. Both intelligent models feature rear panel LEDs which display host activity, errors, locked position, and termination power.

Both switches are backed by a one-year warranty from Digital Controls.
