Safety
Precautions
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 singlechip 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.
