Introduction - Advantech PCM-9570/S User Manual

6.1 Introduction

The PCM-9570/S is equipped with a Symbios SYM53C895
single-chip PCI-to-SCSI host adapter which provides a powerful
Ultra2 multitasking interface between your computer's PCI bus and
SCSI devices (disk drives, CD-ROM drives, scanners, tape backups,
removable media drives, etc.). Up to a total of 15 SCSI devices can be
connected to the SCSI connector through the Symbios SYM53C895.
The SYMBIOS 53C895 is a 16-bit, LVD/SE (Low Voltage
Differential/Single-Ended) SCSI solution for your computer. It can
support both legacy Fast SCSI and Ultra SCSI devices, as well as the
newest LVD Ultra2 SCSI devices.
If you need to configure the SCSI, the on-board SCSI Select
configuration utility allows you to change host adapter settings
without opening the computer or handling the board. The SCSI Select
utility also contains a utility to low-level format and verifies the disk
media on your hard disk drives.
Note:

instead of 80 MBytes/sec.
