1.3.2 The SCSI Interface The SCSI functionality for the LSIU80ALVD is contained within the LSI53C895A. The LSI53C895A connects directly to the SCSI bus and generates signal timing and bus protocol in compliance with the SCSI standard. The SCSI interface on the LSIU80ALVD operates as an 8-bit or 16-bit interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD or SE, Fast, Ultra and Ultra2 SCSI protocols in various combinations. The interface is made through connectors J2 and J3 (s

1.3.3 Ultra2 SCSI Technology The LSIU80ALVD fully supports Ultra2 SCSI. Ultra2 SCSI is an extension of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of standards that expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers. For the internal bus, special impedance SCSI ribbon cables are specified for operation with Ultra and Ultra2 SCSI devices. You must consider the total length of the bus cables and the number of devices on the SCSI bus when setting up yo

1.3.4.1 Benefits of LVDlink The LSI53C895A supports LVD for SCSI, which is a signaling technology that increases the reliability of SCSI data transfers over longer distances than supported by SE SCSI. The low current output of LVD allows the I/O transceivers to be integrated directly into the chip. LVD provides the reliability of HVD SCSI without the added cost of external differential transceivers. Ultra2 SCSI with LVD allows a longer SCSI cable and more devices on the bus, using the same cables

Step 4. Locate the slots for installing a PCI plug-in board. The LSIU80ALVD requires a PCI slot that allows bus master operation. See Table 2.2. Step 5. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use. Save the bracket screw. Step 6. Carefully insert the edge connector J1 of the host adapter into the PCI slot. Make sure the edge connector is properly aligned before pressing the board into place. See Figure 2.2. Note: You may notice that the
