Warning!

Always completely disconnect the power cord
from your chassis whenever you work with the
hardware. Do not make connections while the
power is on. Sensitive electronic components can
be damaged by sudden power surges. Only
experienced electronics personnel should open
the PC chassis.

Caution!

Always ground yourself to remove any static
charge before touching the CPU card. Modern
electronic devices are very sensitive to static
electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all
electronic components in a static-dissipative
surface or static-shielded bag when they are not
in the chassis.

Introduction

The PCM-3430 is featured with the Symbios SYM53C895 Small
Computer System Integrated chip, PC/104 and PC/104 Plus
connection capability. Onboard offers a designated BIOS single-
chip for customer modification.

SYM53C895 PCI/SCSI I/O is a high performance processor that will
add signifcant improvement to your PCI system. SCSI Ultra 2 will
support three different types of SCSI from Fast SCSI, to LVD Ultra 2
SCSI and also Ultra SCSI. The benefit of PCM-3430 is the SCSI
chip can process data and coordinate up to 15 devices which are
simultaneously connected to your mainframe. SCSI is able to carry
out this task through the PCI bus.

SYM53C895 Ultra 2 SCSI implements the LVDlink transceivers, this
technology allows for low voltage differential transfer. Less power
is used allowing for less noise interference and the transfer of data
becomes clearer which will lead to a longer cable.

PC/104 is a connection process where 104 signal pins are attached
to 104 ports on two different buses. PC/104 no longer incorporates
the ISA/PISA bus connection method. This new method of
connection between PC boards or with compact boards has lead to
smaller demensions in board manufacturing.

PC/104 Plus is a connection process where 120 signal pins are
attached to 120 ports on one large bus.

Before You Begin

Symbios the vendor of the SCSI single chip encourages saving all
current data. In case of failure this will insure that precious
information will still be stored elsewhere.

This manual assumes the user is familiar with basic O/S, DOS,
IBM compatibility and proposed standards for SCSI and PCI.
Prior to installing the SCSI driver we recommend connecting your
system to the SCSI controller. Keep in mind you must also assign a
ID code for each device used in your system.

SCSI ID Codes for attached Devices

PCM- 3430 allows up to 15 devices to be connected to your
controller. With so many items running simultaneously SCSI must
assign a ID code for each device. If however the system you are
using is set in the automatic mode (SCAM) you will not have to do
so. There are 16 ID numbers ranging from 0 to 15. ID number 7 is
allocated to the SCSI card. The hard drive must be given the
lowest ID number. Your other peripheral devices are either set with
jumpers or a switch. Refer to the manufacturer's manual to assign a
ID number for each device. If you are able to use the boot
specification (BBS) then the hard drive will not require the lowest
ID number.

Setting the SCSI Adapter

To readjust the setting on the SCSI adapter first you must enter the
SCSI BIOS. Once you have pulled up the SCSI BIOS srceen. You
will find a list of instructions at the bottom of your window. Your
options for setting the SCSI adapters are as follows: configure/view
host adapter setting/SCSI CD utilities.

SCSI Termination

In order to stabilize communication, initial termination of the SCSI
bus must be performed. Terminations must be installed at the
extreme ends of the SCSI cable, and only at the ends. Your system
should have no more than or less than two terminators connected
and active. The peripheral devices that are connected between the
two terminators must have their terminators disabled or removed.
To ensure accidental removel the terminators should be shocketed.

If connecting mutiple devices on the SCSI bus. Those devices that
are located between the two main terminators must have their
terminators deactivated. Located below are some guidelines for
your reference:

· Usually the CPU card itself is automatic in termination.

· Nearly all non-Ultra 2 SCSI devices are manufactured with their
termination enabled.

· Internal Ultra 2 SCSI devices are manufactured with their
termination enabled and can't be changed.

· External SCSI devices may have a switch located in the rear for
termination. If not, they can be terminated by removing or
installing a SCSI terminator.

· Internal SCSI devices can be terminated by simply setting a
jumper or switch. They may also be terminated by installing or
removing a resistor module.
