Single-ended and low voltage differential modes
This drive incorporates two different transceivers to allow you to use it in systems which use
The primary benefits of LVD technology
•Faster transfer rates.
•Reduces power consumption.
•Increases allowable cable lengths.
•Improves device connectivity.
You can configure the drive to switch between SE and LVD modes automatically or force it to operate in SE mode only. To configure this option, use the jumper illustration on page 24 (LW models) or page 34 (LC models).
Note. To operate at the Ultra2 SCSI rates in LVD mode, all devices on the same bus must be running in LVD mode. If you add any
Caution. Do not mix LVD drives on the same bus with devices having high voltage differential (HVD) interface circuits. The circuits are not compatible and drive dam-
age may occur.
