Introduction
The PCM-3420 host adapter offers a wide range of flexible, economical
and expandable solutions that can satisfy diverse needs in SCSI
connectivity. Based on Adpatec’s proven AIC-6360 protocol chip, the
PCM-3420 supports all major operating systems - DOS, Windows,
Windows NT, Netware, UNIX, and OS/2 that permit precise matching
of products to specific requirements, and allows rapid system-level
configurations.
The PCM-3420 is particularly well suited to easy, inexpensive connec-
tion of CD-ROM drivers as well as ideal for connecting a stack of
seven different SCSI peripheral - from hard disks and CD-ROM drives
to tape, DAT and removable-media drives.
Supporting Fast SCSI, with transfer speeds of 10 Mbytes/sec, PCM-
3420 also provides advanced features such as synchronous and
asynchronous data transfer, support for multitasking and full DMA
support.
Whatever the particular configuration, each of the PCM-3420 host
adapter can be relied on for the high levels of quality, compatibility and
reliability.

Jumpers and Connectors
Connectors on the board link it to SCSI devices and other PC/104
modules. In addition, the board has a number of jumpers that allow
you to configure the SCSI application to suit your systems.

Locating Jumpers & Connectors
Setting Jumpers
You configure your PCM-3420 card to match the needs of your
application by setting jumpers. Jumpers are the simplest kind of
electric switch. They consist of two metal pins and a small metal clip
(often protected by a plastic cover) that slides over the pins to
connect them. To close” a jumper you connect the pins with the clip.
To open a jumper you remove the clip. Sometimes a jumper will have
three pins, labeled 1, 2, and 3. In this case you would connect either
pins 1 and 2 or 2 and 3.
The jumper settings are schematically depicted as follows:
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for
your PCM-3420 application, contact your local distributor or sales
representative before you make any changes.

Chapter 2 Hardware Installation 11
Generally, you simply need a standard cable to make most connec-
tions.
Safety Precautions
Always completely disconnect the power cord from your
chassis whenever you are working on it. Do not make connec-
tions while the power is on because sensitive electronic
components can be damaged by the sudden rush of power .
Only experienced electronics personnel should open the PC
chassis.
Always ground yourself to remove any static charge before
touching the card. Modern electronic devices are very sensi-
tive to static electric charges. Use a grounding wrist strap at all
times. Place all electronic components on a static-dissipative
surface or in a static-shielded bag when they are not in the
chassis.

In most cases, you will not need to change these settings.
Jumper Configuration Reference
Nine jumper blocks on the PCM-3420 host adapter are used to config-
ure user-selectable options. The following description shows the
proper jumper settings for their respective applications.
Jumper Block JP2 :
This jumper is used to set the terminator installed or uninstalled.
JP2* 2-3 Close = Terminator Installed
JP2 1-2 Close = Terminator Uninstalled
(* means default setting)
The SCSI bus must be terminated correctly to ensure proper operation
of the PCM-3420 host adapter. Terminators must be installed in the first
and last devices on the SCSI bus and removed from all other SCSI
devices.
Jumper Block JP3 :
This jumper block is used only when DMA is enabled on jumper block
JP6 jumper DT (data transfer mode).
Set DMA Channel 0 = D0 & D0 Close (Others Open)
Set DMA Channel 5 = D5 & D5 Close (Others Open)
Set DMA Channel 6 = D6 & D6 Close (Others Open)
Set DMA Channel 7 = DR & DA Close (Others Open)
You must also select the same interrupt channel with the DC jumpers
on jumper block 5.

Chapter 2 Hardware Installation 13
Jumper Block JP4 :
This jumper block is used to set IRQ channel. You must also set the
corresponding IC jumper on jumper block 5.
SetIRQ12 =Jumper12 Close , Others Open
SetIRQ11 * = Jumper11 Close , Others Open
SetIRQ10 =Jumper10 Close , Others Open
SetIRQ9 = Jumper 9 Close , Others Open (Not
recommendedwith Windows 3.x)
(* means default setting)
Jumper Block JP5 :
This jumper block provides four functions eight jumper to set the
PCM-3420 host adapter configuration , including SCSI ID , IRQ
channel , DMA channel , and parity checking.
JP5 Set PCM-3420 host adapter SCSI ID :
ID SD0 SD1 SD2
0 Close Close Close
1 Open Close Close
2 Close Open Close
3 Open Open Close
4 Close Close Open
5 Open Close Open
6 Close Open Open
7 * Open Open Open
(* means default setting)
JP5 Set PCM-3420 host adapter IRQ Channel :
IRQ IC0 IC1
9 Close Close (JP4/IRQ 9 also set close)

14 PCM-3420 User's Manual
10 Open Close (JP4/IRQ10 also set close)
11* Close Open (JP4/IRQ11 also set close)
12 Open Open (JP4/IRQ12 also set close)
(* means default setting)
Jumper Block JP4 also needs to set to the same IRQ channel.
JP5 Set PCM-3420 DMA Channel :
This setting is valid only if DMA is enabled on JP6 (DT - data transfer
mode). (Jumper Block JP3 must also be the same DMA channel)
DMA DC1 DC2
0 * Close Close (JP3/DMA0 also set close)
5 Open Close (JP3/DMA5 also set close)
6 Close Open (JP3/DMA6 also set close)
