Hardware Overview
The NI PXI-8214 PXI-to-Ultra2 SCSI Host Adapter provides an Ultra2
SCSI interface to PXI or CompactPCI (cPCI) systems. The PXI-8214 is a
16-bit Low Voltage Differential (LVD)/Single-Ended (SE) SCSI solution
you can use to connect up to 15 SCSI devices. Data transfer rates of up to
40 MegaTransfers (MT)/s (80 Mbytes/s) are possible. The PXI-8214 is an
ideal solution for the PXI/cPCI system that requires true high-speed
continuous disk operation.
