PRODUCT OVERVIEW
SCSI Interface
The
master host adapter product based on a BusLogic-designed, universal ASIC
technology. It provides a high-performance interconnection between the
Video Electronics Standards Association’s
and Small Computer System Interface (SCSI) peripheral devices. It is designed for multitasking operating systems such as UNIX, XENIX, NetWare,
as well as DOS. UNIX and XENIX both contain built-in driver sup-

HOST ADAPTER INTEGRATION
Cabling Requirements
This section describes device termination, cabling requirements, and SCSI
device ID selection.
Device Termination
SCSI devices are daisy chained together with a common cable. All SCSI
devices operate on common signals and both ends of the cable are terminated with hardware terminators. Terminators, which can be connected to
either SCSI devices or SCSI cables, are required to make data transfers on
the SCSI bus reliadle.
Devices connected to SCSI chains must have the correct number of terminators for proper operation and to prevent damage to the SCSI chip on the
There can be no more than two terminators in a chain of SCSI
devices-one at each end of the physical chain. Thus if more than two SCSI
devices are connected in a SCSI daisy chain, the middle device(s) in the
control cable must have the terminator resistor packs on the device(s)
removed. See Figure 2-1 for possible configurations of terminators in a SCSI
system.

SCSI
Device
SCSI
Device
Selecting the proper SCSI cable for a particular system configuration is
of great importance. If two or more SCSI devices are configured in a SCSI
daisy chain, the devices must be connected by a .%-conductor, daisy-chain
cable.
Before plugging in cable connectors, check that the
mark molded on
the connector or the colored stripe on the cable (indicating the location of
Pin 1) matches Pin 1 of the connector on the
SCSI Device ID Selection
The SCSI ID is a number between 0 and 7 assigned to any SCSI device. The
SCSI ID number is used by the computer to communicate with the devices
connected to it. All SCSI devices must have a unique SCSI number to
identify it on the SCSI chain. When two or more SCSI devices communicate, a SCSI device is usually fixed as either an initiator or a target; however,
some devices are capable of performing either role. Devices with higher
ID numbers have a higher priority in communicating with the computer.
Most SCSI peripheral devices are shipped with a preassigned SCSI ID
number. A SCSI ID switch is usually located on the back panel of such
devices. Change the SCSI ID of other peripheral devices only as recom-
mended in the owner’s manual. Refer to the earlier heading

PROM, the local RAM and internal data buses are tested. Results of the tests
are indicated by an LED on the board.
The LED will first turn on when power is applied. If the diagnostics find no
malfunctions, the LED will then go off. In normal operation, the LED will
be illuminated when command or SCSI bus activity occurs on the board.
If an error is detected by the diagnostics, the LED will repeatedly flash a
specific number of times, with a long pause between flashes, to indicate the
board function which failed. This will continue until the board is powered
