1.1 Introduction
The PCM-3350 is the ultimate cost-effective solution for limited space
applications. It is a new NS Geode Biscuit PC with enhanced graphics
function. It uses a NS CS5530A chipset which supports TFT LCDs. It
offers all the functions of an AT-compatible industrial computers on a
single board. The PCM-3350 comes with an embedded high-perfor-
mance GX1-300 processor on-board. For maximum performance, the
PCM-3350 Series also supports an SDRAM SODIMM socket that can
accept up to 128 MB memory.
On-board features include an Ethernet interface, socket for Compact
Flash Card, Enhanced IDE interface with up to Ultra DMA transfer
protocol, one parallel port, two serial ports (RS-232 and RS-232/422/
485) and a PS/2 keyboard/mouse interface. A SVGA/LCD display
controller (LCD, and CRT displays) allows LCD screen resolutions up
to 1024 x 768 and CRT resolutions up to 1280 x 1024 @ 16 colors.
The PCM-3350 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 the software. A single
Flash chip holds the system BIOS and the VGA BIOS. This minimizes
the chip usage and eases configuration. You can change the display
BIOS simply by programming the Flash chip.
If you need additional functions, the PCM-3350 has a PC/104 connec-
tor for future upgrades.

2.6 Serial ports
(CN3: COM1; CN4: COM2/RS-232;
CN18: COM2/RS-422/485)
The PCA-3350F offers two serial ports: COM1 in RS-232 and COM2
(CN4: RS-232, CN18:RS-422/485). Refer to CMOS "Integrated Peripher-
al" for RS-232, 422 or 485 settings. These ports let you connect to
serial devices (mouse, printers, etc.) or a communication network.
You can select the address for each port (for example, 3F8H [COM1],
2F8H [COM2]) or disable each port. Use the BIOS Advanced Setup
program, which is covered in Chapter 4.
The card mounting bracket holds the serial port connector for the one
port. The parallel port and serial port adapter kit (supplied with the
card) holds the connector for the other port. This lets you connect and
disconnect cables after you install the card. The DB-9 connector on
the bottom of the bracket is the first RS-232 port, COM1. The DB-9
connector on the adapter kit is the second serial port, COM2.

2.7 EIDE HDD connector (CN5)
The built-in Enhanced IDE (Integrated Device Electronics) controller
supports up to two IDE devices, including CD-ROM drives, tape
backup drives, a large hard disk drive and other IDE devices.
2.7.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one or
two cables, depending on the drive size.
IDE 1.8" and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable
connector (included). IDE 3.5" drives need a 1 x 44-pin to 2 x 40-pin
connector (not included).
Wire number 1 on the cable is red or blue, and the other wires are gray.
1. Connect one end of the cable to CN5. Make sure that the red (or
blue) wire corresponds to pin 1 on the connector, which is labeled
on the board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard drive.
Unlike floppy drives, IDE hard drives can connect to either end of
the cable. If you install two drives, you will need to set one as the
master and one as the slave by using jumpers on the drives. If you
install just one drive, set it as the master.
2.8 PC/104 connector (CN6)
Refer to Appendix B in this manual.

2.9 Parallel port connector (CN7)
Normally, the parallel port is used to connect the card to a printer. The
PCM-3350 includes a multi-mode (ECP/EPP/SPP) parallel port. It is
accessed via CN7, a 26-pin flat-cable connector.
You will need an adapter cable if you use a traditional DB-25 connec-
tor. The adpater cable should have a 26-pin connector on one end and
a DB-25 connector on the other.
The parallel port interrupt channel is designated as IRQ7.
2.10 Backlight connector (CN8)
The LCD inverter is connected to CN8 via a 4-pin connector to provide
+12 V power to the LCD display.
2.11 VGA connector (CN9)
The PCM-3350 board's SVGA interface can facilitate conventional CRT
displays. The card has a connector to support CRT VGA monitors.
2.11.1 CRT display connector (CN9)
CN9 is a 16-pin, pin head housing connector. Please use the VGA cable
(provided with your kit) to convert the pin head housing connector
into a connector for conventional CRT displays.
Detailed information on pin assignments for CRT display connector
CN9 is given in Appendix C.
2.12 Main power (+5 V / +12 V) connector
(CN11)
This supplies main power to the PCM-3350 (+5 V), and also 12 V power
to the backlight connector.

2.13 PS/2 keyboard/mouse connector
(CN12)
The PCM-3350 board provides a pin head keyboard connector, which
supports both a keyboard and a PS/2 style mouse. In most cases,
especially in embedded applications, a keyboard is not used. If the
keyboard is not present, the standard PC/AT BIOS will report an error
or failure during the power-on self test (POST) after resetting the PC.
The PCM-3350 board's BIOS standard setup menu allows you to select
"Absent/Present" for your keyboard under the Advanced CMOS
Setup section. This allows non-keyboard operation in embedded
system applications without the system halting during the POST.
When "PS/2 mouse support" is enabled, your PS/2 mouse is automati-
cally detected by the system.
2.14 FDD connector (CN14)
You can attach one 3.5" floppy drive to the the PCM-3350's onboard
controller. This is useful for notebooks, for example.
A daisy-chain drive cable converter (part no. 9681000044) is required
for a single floppy system. A 34-pin flat-cable connector is fitted on
one end of the cable converter, while the other end has one floppy disk
drive connector. It consists of a 34-pin flat-cable connector (for the
3½” drives).
2.13.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into the cable converter. Make
sure that the red wire corresponds to pin 1 on the connector.
2. Attach the appropriate conector at the other end of the cable to the
floppy drive(s). You can use only one connector in the set. The set
at the other end (after the twist in the cable) connects to the A:
drive.
When connecting a 3½” floppy drive, you may have some difficulties
in determining which pin is number one. Look for a number on the
circuit board indicating pin number one. In addition, you should check
if the connector on the floppy drive has an extra slot. If the slot is up,
14
PCM-3350 User's Manual

pin number one should be on the right. Please refer to any documenta-
tion that came with the drive for more information.
If your cable needs to be custom made, you can find the pin assign-
ments for the board's connector in Appendix C.
2.15 CompactFlash™ socket (CN16)
The PCM-3350 is equipped with a CompactFlash™ Type I disk socket
on the solder side, which supports the IDE interface CompactFlash
disk card. The socket itself is specially designed to prevent any
incorrect installation of the CompactFlash disk card. When installing
or removing the CompactFlash disk card, please make sure that the
system power is off.
The CompactFlash™ disk card is defaulted as the E disk drive in your
PC system. To fit the EMAC CFC into the PCM-3350, simply plug
it into the designated connector. It will only fit when the red triangle on
the CFC is aligned with the triangle on the connector. The card will not
fit any other way (do NOT use excessive force).

3.1 Introduction
The PCM-3350 system BIOS and custom drivers are located in a 256
KB, 32-pin Flash ROM device, designated U17. A single Flash chip
holds the system BIOS and VGA BIOS. The display type can be
configured via software. This method minimizes the number of chips
and eases configuration. You can change the display BIOS simply by
reprogramming the Flash chip.
3.2 Utility CD disk
The PCM-3350 is supplied with a software utility on CD-ROM. This
disk contains the necessary file for setting up the VGA display.
Directories and files on the disk are as follows:
AWDFLASH.EXE
CBROM.EXE
3350Vxxx.BIN
Figure 3-1: Contents of the PCM-3350 Series utility disk
AWDFLASH.EXE
This program allows you to update the BIOS Flash ROM.
3350110.BIN
This binary file contains the system BIOS.
CBROM.EXE
This program allows you to combine your own VGA BIOS with
system BIOS (3350V110.BIN).
3.3 VGA display software configuration
The PCM-3350 on-board VGA/LCD interface supports an 18-bit TFT
LCD, flat panel displays and traditional analog CRT monitors. The
interface can drive CRT displays with resolutions up to 1024 x 768 in 24
bpp. It is also capable of driving color panel displays with resolutions
of 1024 x 768 in 18 bpp. The LCD type is configured completely via the
software utility, so you do not have to set any jumpers. Configure the
LCD type as follows:

4.1 System test and initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors. Non-fatal error messages
usually appear on the screen along with the following instructions:
press <F1> to RESUME
Write down the message and press the F1 key to continue the
bootup sequence.
4.1.1 System configuration verification
These routines check the current system configuration against the
values stored in the board’s CMOS memory. If they do not match,
the program outputs an error message. You will then need to run
the BIOS setup program to set the configuration information in
memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The PCM-3350 CMOS memory has an integral lithium battery
backup. The battery backup should last ten years in normal service,
but when it finally runs down, you will need to replace the complete
unit.

Programming the
Watchdog Timer
The PCM-3350 is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for any reason. This feature
ensures system reliability in industrial
standalone or unmanned
environments.
Download from Www.Somanuals.com. All Manuals Search And Download.
A.1 Programming the watchdog timer
The default configuration of the timer is enabled with system reset.
To enable the watchdog timer, you must make a program which
writes 1 to I/O port address 443 (hex) at regular intervals. The first
time your program reads the port, it enables the watchdog timer. After
that, your program must write 1 to port 443 at time intervals of less
than 1.6 seconds. Otherwise, the watchdog timer will activate and
reset the CPU. When you want to disable the watchdog timer, your
program should write 0 to port 443.
If CPU processing comes to a standstill because of EMI or a software
problem, your program's signals to I/O port address 443 of the timer
will be interrupted. The timer will then automatically reset the CPU,
and data processing will continue normally.
You must make your program so that it writes 1 to I/O port 443 at an
interval shorter than the timer's preset interval. The timer's intervals
have a tolerance of ± 30%, so you should program an instruction that
will refresh the timer about every second.

B.1 Installing PC/104 modules
The PCM-3350's PC/104 connectors give you the flexibility to attach
PC/104 modules.
Installing these modules on the PCM-3350 is quick and simple. The
following steps show how to mount the PC/104 modules:
1. Remove the PCM-3350 from your system paying particular atten-
tion to the safety instructions already mentioned above.
2. Make any jumper or link changes required to the CPU card 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 CPU card by pressing the
module firmly but carefully onto the mounting connectors.
5. Secure the PC/104 module onto the CPU card using the four
mounting spacers and screws.
