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)

Connector Function
COM1 RS-232 COM2 RS-232/422/485

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.

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.

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.

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.
58 PCM-3350 User's Manual
The following example shows how you might program the watchdog timer in BASIC:
