Sections include:

• Introduction

• Features

• Specifications

• Board layout and dimensions

1 Chapter 1 General Information

Chapter 1 Introduction

1.1 Introduction

The PCM-9340 is the ultimate cost-effective solution for limited-space
applications. It offers all the functions of an AT-compatible industrial
computer on a single board. The PCM-9340 comes with an embedded
high-performance STPC Elite 133 processor and 32MB SDRAM on
board. For maximum performance, the PCM-9340 also supports one
optional SODIMM socket that can accept up to 64 MB memory.

On-board features include an Ethernet interface, a socket for DOC®
2000, Enhanced IDE interface, one parallel port, four serial ports (three
RS-232s, and one RS-232/422/485) with DB-9 connectors, and a mini­DIN PS/2 keyboard/mouse interface, and an optional audio function. An
SVGA/LCD display controller (LCD, and CRT displays) allows LCD
screen resolutions up to 1024 x 768 @ 64K colors and CRT resolutions
up to 1280 x 1024 @ 256 colors.

The PCM-9340 complies with the “Green Function” standard and sup­ports three types of power saving features: Normal, Doze and Sleep
modes.

The display type configuration is done through software. A single Flash
chip holds the system BIOS and the VGA BIOS. This minimizes the
number of chips and eases configuration. You can change the display
BIOS simply by programming the Flash chip.

If you need any additional functions, the PCM-9340 has a PC/104 con­nector for future upgrades.

CHAPTER

Connecting Peripherals

This chapter tells how to connect
peripherals, switches, and indicators to the
PCM-9340 board. It also covers jumper
settings. You can access most of the con­nectors from the top of the board while it
is installed in the chassis. If you have a
number of cards installed, or your chassis
is very tight, you may need to partially
remove the card to make all the connec­tions.

7 Chapter 2 Connecting Peripherals

Chapter 2 Installation

2.1 Jumpers

The PCM-9340 has a number of jumpers that allow you to configure your
system to suit your application.

JP3 Watchdog timer action
JP4 DOC® 2000 address setting
JP5 Clear CMOS
JP7 Audio power selector

2.1.3 Setting Jumpers

You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir­cuit. It consists 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.

open closed closed 2-3

The jumper settings are schematically depicted in this manual as follows:.

open closed 2-3 closed

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
application, contact your local distributor or sales representative before
you make any changes.

2.3 Watchdog Timer Action (JP3)

An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu­able protective device for standalone or unmanned applications. Setup
involves one jumper setting and running the control software (refer to
Appendix A).

When the watchdog timer activates (CPU processing has come to a halt),
it can either reset the system or generate an interrupt on IRQ11. This
choice for watchdog timer action is set via JP3 as shown below:

2.8 Making Connections

The following sections tell how to make each connection. In most cases,
you will simply need to connect a standard cable. All of the connector pin
assignments are shown in Appendix C.

Warning!

Caution!

Always completely disconnect the power cord
from your chassis whenever you are working
on it. Do not make connections while the power
is on. Sensitive electronic components can be
damaged by a sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.

Always ground yourself to remove any static
charge before touching the CPU 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. This is
especially important where the ambient air is
very dry.

2.9 CPU Fan power supply connector (CN1)

Provides power supply to CPU cooling fan. Only present when +5 V and
+12 V power is supplied to the board.

2.10 Serial ports (CN2, CN3, CN4)

The PCM-9340 offers four serial ports: three RS-232 (COM 1, 3, 4) and
one RS-232/422/485 (COM 2). These ports allow you to connect to any
serial device (a mouse, a printer, etc.) or to a communication network.

2.10.1 COM3/COM4 RS-232 port (CN2)

The COM3/COM4 series port, consists of 20 pin dual-in-line, male
header.

15 Chapter 2 Connecting Peripherals

2.10.2 COM2 RS-232/422/485 selection (CN3)

This secondary port between CN2 and CN4 consists of a 14-pin, dual-in­line, male header, and can be configured, via JP2 (q.v.), to operate in RS-
232, RS-422, or RS-485 mode.

The IRQs and address ranges for the COM ports are fixed. However, if
you wish to disable a port or change these parameters later, you can do
this in the system BIOS setup.

2.10.3 COM1 RS-232 port (CN4)

This serial port connector is the 9-pin D-SUB connector toward the left
side.

2.10.4 Share IRQ

The IRQ and the address range for COM1, 2, 3, 4 default are fixed. How­ever, if you wish to disable the port or change these parameters later, you
can do this in the system BIOS setup. The table below shows the settings
for the PCM-9340's serial ports.

2.13 Keyboard and PS/2 mouse connector (CN7)

The PCM-9340 board provides a keyboard connector. A 6-pin mini-DIN
connector (CN7) on the card mounting bracket supports singleboard com­puter applications. The card comes with an adapter to convert from the 6­pin mini-DIN connector to a standard DIN connector and to a PS/2 mouse
connector.

17 Chapter 2 Connecting Peripherals

2.14 IR connector (CN8)

This connector supports the optional wireless infrared transmitting and
receiving module. This module mounts on the system case. You must
configure the setting through BIOS setup.

2.15 Enhanced IDE HDD Connector (CN9)

You can attach two IDE (Integrated Device Electronics) drives to the
PCM-9340 internal controller. The PCM-9340 SBC card has an EIDE
connector, CN9.

Wire number 1 on the cable is red or blue, and the other wires are gray.
Connect one end to connector CN9 on the PCM-9340. Make sure that the
red (or blue) wire corresponds to pin 1 on the connector. See Figure 2-1,
where pin 1 is indicated with a triangle or a solid square.

Unlike floppy drives, IDE hard drives can connect in either position on
the cable. If you install two drives, you will need to set one as the master
and one as the slave. You do this by setting the jumpers on the drives. If
you use just one drive, you should set it as the master. See the documenta­tion that came with your drive for more information.

Connect the first hard drive to the free end of the cable. Wire 1 on the
cable should also connect to pin 1 on the hard drive connector, which
should be labeled on the drive circuit board. Check the documentation
that came with the drive for more information. If you are using a second
drive, connect it to the remaining connector on the same cable.

2.16 VGA interface connections (CN10, CN15, CN19)

The PCM-9340’s PCI SVGA interface can drive conventional CRT dis­plays and is capable of driving a wide range of flat panel displays, includ­ing passive and active LCD displays. The board has two connectors to
support these displays, one for standard CRT VGA monitors and one for
flat panel displays.

2.16.1 CRT display connector (CN10)

CN10 is a 16-pin, dual-inline header used for conventional CRT displays.
A simple one-to-one adapter can be used to match CN10 to a standard 15­pin D-SUB connector commonly used for VGA.

Pin assignments for CRT display connector CN18 are detailed in Appen­dix C.

PCM-9340 User’s Manual 18

2.16.2 Extension flat panel connector (CN15)

CN15 consists of a 20-pin connector which is Hirose’s product no.
DF13A-20DP-1.25V. The PCM-9340 supports a 36-bit LCD panel which
must be connected to both the CN19 (40-pin) and the CN15 (20-pin). The
pin assignments for both CN19 and the CN15 can be found in Appendix
C.

2.16.3 Flat panel display connector (CN19)

CN19 consists of a 40-pin connector which can support a 24-bit LCD
panel. It is Hirose’s product no. DF13A-40DP-1.25 V

The PCM-9340 provides a bias control signal on CN19 that can be used
to control the LCD bias voltage. It is recommended that the LCD bias
voltage not be applied to the panel until the logic supply voltage (+5 V or
+3.3 V) and panel video signals are stable. Under normal operation, the
control signal (ENAVEE) is active high. When the PCM-9340’s power is
applied, the control signal is low until just after the relevant flat panel sig­nals are present.

2.17 Audio interfaces (CN11, CN17) (optional)

The PCM-9340 is equipped with a high-quality audio interface, which
provides 16-bit CD-quality recording and playback as well as OPL3 com­patible FM music. It is supported by all major operating systems.

2.17.1 Audio connector (CN11)

The PCM-9340 provides all major audio signals on a 16-pin flat-cable
connector, CN11. These audio signals include Microphone in (mono),
Line in (stereo), Line out (stereo), and Speaker out (stereo). If you use tra­ditional telephone jack connectors for these audio signals, you will need
an adapter cable.

2.17.2 CD audio input connector (CN17)

Any CD-ROM drive can provide analog audio signal output when used as
a music CD player. The CN17 on PCM-9340 is a connector to input CD
audio signals into the audio controller. The audio cable of your CD-ROM
drive will be used to connect to CN17.

2.17.3 Audio power source setting (JP7)

The PCM-9340 is designed to work with a single +5 V power supply. The
audio interface can also function normally under single +5V power sup­ply, but most audio controllers require an independent power source gen­erated from a +12 V power supply. The independent power source avoids
the noise from the other digital circuits. The PCM-9340’s audio interface

19 Chapter 2 Connecting Peripherals

can accept +12 V power to provide improved quality audio. This is done
via JP7.)

Table 2.11: JP7: Audio Power Source Setting

Pins Function

2.19 FDD connector (CN14)

You can attach up to two floppy disk drives to the PCM-9340's onboard
controller. You can use any combination of 5.25" (360 KB/1.2 MB) and/
or 3.5" (720 KB/1.44/2.88 MB) drives.

The card comes with a 34-pin daisy-chain drive connector cable. On one
end of the cable is a 34-pin flat-cable connector. On the other end are two
sets of floppy disk drive connectors. Each set consists of a 34-pin flat­cable connector (usually used for 3.5" drives) and a printed-circuit-board
connector (usually used for 5.25" drives). You can use only one connector
in each set. The set on the end (after the twist in the cable) connects to the
A: floppy. The set in the middle connects to the B: floppy.

2.20 Parallel port connector (CN18)

The parallel port is designated as LPT1, and is normally used to connect
the CPU card to a printer. The PCM-9340 includes an on-board parallel
port, accessed through a 26-pin flat-cable connector, CN18. The card
comes with an adapter cable which lets you use a traditional DB-25 con­nector. The cable has a 26-pin connector on one end and a DB-25 connec­tor on the other, mounted on a retaining bracket. The bracket installs at
the end of an empty slot in your chassis, giving you access to the connec­tor.

To install the bracket, find an empty slot in your chassis. Unscrew the
plate that covers the end of the slot. Screw in the bracket in place of the
plate. Next, attach the flat-cable connector to CN18 on the CPU card.
Wire 1 of the cable is red or blue, and the other wires are gray. Make sure
that wire 1 corresponds to pin 1 of CN18. Pin 1 is on the right side of
CN18.

2.21 General Purpose Input Output (CN20)

The PCM-9340 supports 8-bit GPIO through CN20. The 8 digital in- and
out-puts can be programmed to read or control devices, with input or out­put defined. The default setting is 4 bits input and 4 bits output.

Appendix B Installing PC/104 Modules

B.1 Installing PC/104 Modules

The PCM-9340's PC/104 connectors give you the flexibility to attach PC/
104 modules.

Installing these modules on the PCM-9340 is quick and simple. The fol­lowing steps show to mount the PC/104 modules:

1. Remove the PCM-9340 from your system, paying particular atten-

tion to the safety instructions mentioned previously.

2. Make any jumper or link changes required to the biscuit SBC now.

Once the PC/104 module is mounted, you may have difficulty in
accessing these.

3. Normal PC/104 modules have male connectors and mount directly

onto the main card. (Refer to the diagram on the following page.)

4. Mount the PC/104 module onto the biscuit SBC by pressing the

module firmly but carefully onto the mounting connectors.

5. Secure the PC/104 module onto the biscuit SBC using the four

mounting spacers and screws.
