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 Peripheral" 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.
Table 2-2: Serial port connections (COM1, COM2)

COM1 RS-232
COM2 RS-232/422/485
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
Chapter 2 Installation 11
this in the system BIOS setup. The table below shows the settings for
the PCA-3350F Series' board's ports:
Table 2-3: Serial port default settings
Port Address Interrupt Default
COM1 3F8, 3E8 IRQ4 3F8
COM2 2F8, 2E8 IRQ3 2F8
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 connector. 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 automatically 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 documentation that came with the drive for more information.
If your cable needs to be custom made, you can find the pin assignments 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.

2.17.1 Auxilary power connector (MJ1-A)
Supplies secondary power to peripherals that require -5 V and
-12 V.

2.17.2 Fan connector (MJ1-B)
The PCM-3350 is equipped with a low power dissipation GX1 CPU.
With only a heat sink, the PCM-3350 will operate normally at temperatures up to 60° C. At temperatures above 60° C, a fan is recommended.
A CPU fan power supply connector is provided (+5 V input) in
addition to the CPU power supply.
This provides power supply to the optional CPU cooling fan. This
connector is only available when +5 V power is supplied to the board.
Warning! Before making the connection, make sure that the
voltage is absolutely correct and matched with the
correct connector.
2.17.3 Reset button connector (MJ1-C)
If you install a reset button, it should be a single pole switch rated at
5 V. Momentarily pressing the button will activate a reset.
For reset button pin assignments, please see Appendix C.
2.17.4 IR connector (MJ1-D)
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.
2.17.5 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.

2.18 SO DIMM socket (Slot1)
You can install anywhere from 8 MB to 128 MB of onboard SDRAM
memory using 8, 16, 32 or 128 MB 144-pin SODIMMs (Small Outline
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.
