FEATURES
• LVD technology is fully compatible with
older SCSI devices including Ultra-wide,
single-ended SCSI devices.
External Ultra2 LVD SCSI Cable
• Extend your SCSI bus to 12 meters
and connect RAID drives and mass
storage devices.
• Transfer data at up to 80 MBps across
the entire SCSI bus.
Internal Ultra2 LVD SCSI Cable
• For internal, 68-in, Ultra2 wide devices.
• Connects multiple internal devices.
• Use for internal single-ended and
different SCSI applications that require
twisted pairs.
Ultra2 LVD SCSI Terminators
• Terminate 80-MBps LVD and single-
ended SCSI buses.
OVERVIEW
External Ultra2 LVD SCSI Cable
Constructed of double-shielded twisted pair, these cables
transfer data at up to 80 MB per second across the entire
SCSI bus.
The External Ultra2 LVD SCSI Cables are fully compatible
with older SCSI devices, including Ultra-Wide single-ended
SCSI devices. And they can increase your SCSI bus length to
up to 12 meters!
Internal Ultra2 LVD SCSI Cable
Use the Internal Ultra2 LVD SCSI Cables for internal single-
ended or differential SCSI applications requiring twisted pairs.
These cables feature flat sections and loose, unbonded
twisted pairs that are perfect for connecting multiple internal
devices. And they terminate to industry-standard 0.025" IDC
connectors.
Ultra2 LVD SCSI Terminators
Select either internal or external models that support
termination for both LVD and/or single-ended SCSI buses.
All models support the 80-MB-per second LVD specification.
Connect the internal terminator directly on the internal
flat ribbon cable assembly.
The external terminators feature an LED that identifies
the bus being terminated for LVD or single-ended devices.
And to ensure secure VHDC1 and Micro D68 connections,
thumbscrew connections are provided.
