the PCM-3350.  
Sections include:  
• Introduction  
• Features  
• Specifications  
• Board dimensions  
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.

2.3 Safety precautions  
Warning! Always completely disconnect the power cord from  
your board whenever you are working on it. Do not  
make connections while the power is on, because  
sensitive electronic components can be damaged by  
a sudden rush of power.  
Caution! Always ground yourself to remove any static charge  
before touching the board. 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.  
2.4 Ethernet connector (CN1)  
(PCM-3350F/N only)  
The PCM-3350F/N is equipped with a high performance 32-bit PCI-bus  
Fast Ethernet interface which is fully compliant with IEEE 802.3u  
100/10Base-T specifications. It is supported by all major network  
operating systems.  
2.4.1 Ethernet connector (CN1)  
10/100Base-T connects to the PCM-3350F/N via an adapter cable to  
the 10-pin 2 mm connector.  
2.4.2 Network boot  
The network boot feature is built into the BIOS. It can be enabled or  
disabled in the chipset setup of the CMOS configuration. Refer to  
"BIOS Setting" in Chapter 4 for more information.  
2.5 LCD display connector (CN2)

PCM-3350 User's Manual  
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.

2.6.1 RS-232 connection (COM1: CN3)  
Different devices implement the RS-232 standard in different ways. If  
you are having problems with a serial device, be sure to check the pin  
assignments for the connector.  
2.6.2 RS-232/422/485 connection  
(COM2: CN4: RS-232; CN18: RS-422/485)  
COM2 is an RS-232/422/485 serial port. You can select one of these  
functions via BIOS, as detailed in Chapter 4.  
The IRQ and address range for both ports are fixed. However, if you  
wish to disable the port or change these parameters later, you can do

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.  
12  
PCM-3350 User's 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.  
Chapter 2 Installation  
13  
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).  
2.16 USB connector (CN17)  
The PCM-3350F board provides two USB (Universal Serial Bus)  
interfaces, which give complete plug and play and also hot  
attach/detach for up to 127 external devices. The USB interfaces  
comply with USB specification rev. 1.0 and are fuse protected.  
The USB interfaces are accessed through a 8-pin flat-cable connector,  
CN17. The adapter cable has a 8-pin connector on one end and a USB  
connector on the bracket.  
The USB interfaces can be disabled in the system BIOS setup.

must configure the setting through BIOS setup.  
2.17.5 Watchdog timer configuration (MJ1-E)  
An onboard 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 two jumpers and running the control software (refer to  
Appendix A).  
Whnen the watchdog timer is enabled and the CPU shuts down, the  
watchdog timer will automatically either reset the system or generate  
an interrupt on IRQ11, depending on jumper MJ1-E settings.

Dual Inline Memory Modules).  
2.18.1 Installing SODIMMs  
Note:  
The modules can only fit into a socket one way. Their  
gold pins must point down into the SODIMM socket.  
The procedure for installing SODIMMs appears below. Please follow  
these steps carefully.  
SO DIMM installation  
1. Make sure that all power supplies to the system are switched off.  
2. Install the SODIMM card. Install the SODIMM so that its gold pins  
point down into the SODIMM socket.  
3. Slip the SODIMM into the socket at a 45 degree angle and carefully  
fit the bottom of the card against the connectors.  
4. Gently push the SODIMM into a perpendicular position until the  
clips on the ends of the SODIMM sockets snap into place.  
5. Check to ensure that the SODIMM is correctly seated and all  
connector contacts touch. The SODIMM should not move around in  
its socket.  
Important: Only use standard form SODIMM memory modules  
(as shown in the diagram below). Standardized  
dimensions ensure a proper fit. Check with your  
memory supplier about the SODIMM modules you will  
use.

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:

Award BIOS Setup  
This chapter describes how to set BIOS  
configuration data.  
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.  
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.

Installing PC/104  
Modules  
This appendix gives instructions for  
installing PC/104 modules.  
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.
