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 connection 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, DA T and removable-media drives.
Supporting Fast SCSI, with transfer speeds of 10 Mbytes/sec, PCM3420 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. T o close” a jumper you connect the pins with the clip.
T o 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.

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.

Safety Precautions
Always completely disconnect the power cord from your
chassis whenever you are working on it. Do not make connections while the power is on because sensitive electronic
Caution !
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 sensitive 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.

Jumper Configuration Reference
Nine jumper blocks on the PCM-3420 host adapter are used to configure 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 = T erminator Installed
JP 2 1-2 Close = T erminator 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.
12 PCM-3420 User's Manual
Jumper Block JP4 :
This jumper block is used to set IRQ channel. You must also set the
corresponding IC jumper on jumper block 5.
Set IRQ 12 = Jumper 12 Close , Others Open
Set IRQ 11 * = Jumper 11 Close , Others Open
Set IRQ 10 = Jumper 10 Close , Others Open
Set IRQ 9 = Jumper 9 Close , Others Open (Not
recommended with 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
