1.4 Safety precautions

Follow these simple precautions to protect yourself from harm and your PC from damage.

1. To avoid electric shock, always disconnect the power from your PC chassis before you work on it. Do not touch any components on the CPU card or other cards while the PC is on.

2. Disconnect power before making any configuration changes. The sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.

3. Always ground yourself to remove any static charge before you touch your CPU card. Be particularly careful not to touch the chip connectors. Modern integrated electronic devices, especially CPUs and memory chips, are extremely sensitive to static electric discharges and fields. Keep the card in its antistatic packaging when it is not installed in the PC, and place it on a static dissipative mat when you are working with it. Wear a grounding wrist strap for continuous protection.

6 PCA-6751 Series User's Manual

1.5 Jumper settings

1.5.1 Introduction

This section tells how to set the jumpers to configure your card. It gives the card default configuration and your options for each jumper. After you set the jumpers and install the card, you will also need to run the BIOS Setup program (discussed in Chapter 3) to configure the serial port addresses, floppy/hard disk drive types and system operating parameters. Connections, such as hard disk cables, appear in Chapter 2.

For the locations of each jumper, see the board layout diagram depicted earlier in this chapter.

You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal cap (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, connect the pins with the cap. To "open" a jumper, remove the cap. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you connect either pins 1 and 2 or 2 and 3.

Closed 2-3Open Closed

You may find a pair of needle-nose pliers useful for setting the 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.

1.5.6 Watchdog timer configuration (JP4)

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.)

When the watchdog timer is enabled and the CPU shuts down, the watchdog timer will automatically either reset the system or generate an interrupt on IRQ 11, depending on the setting of jumper JP4, as shown below:

1.6 Installing system memory (SODIMMs)

You can install anywhere from 8 to 256 MB of SDRAM into your PCA-6751 Series card. The card provides two 144-pin SODIMM sockets. Each socket accepts 8, 16, 32, 64 or 128 MB 3.3 V power level SODIMMs. If only one SODIMM module is installed, it may be installed in either SODIMM socket on the solder side of the PCA-6751 Series card.

Note: PCA-6751 Series cards only support SDRAM

SODIMM modules. EDO SODIMM is not supported.

1.6.1 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.

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.

Chapter 1 Hardware Configuration 13

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 PCA-6751 Series 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

To program the watchdog timer, you must write a program which writes I/O port address 443 (hex). The output data is a value of time interval. The value range is from 01 (hex) to 3E (hex), and the related time interval is 1 sec. to 62 sec.

Data Time Interval

01 1 sec. 02 2 sec. 03 3 sec. 04 4 sec.

••

3E 62 sec.

70 PCA-6751 Series User's Manual

After data entry, your program must refresh the watchdog timer by rewriting the I/O port 443 (hex) while simultaneously setting it. When you want to disable the watchdog timer, your program should read I/O port 443 (hex).

The following example shows how you might program the watchdog timer in BASIC:

10 REM Watchdog timer example program 20 OUT &H443, data REM Start and restart the watchdog 30 GOSUB 1000 REM Your application task #1, 40 OUT &H443, data REM Reset the timer 50 GOSUB 2000 REM Your application task #2, 60 OUT &H443, data REM Reset the timer 70 X=INP (&H443) REM, Disable the watchdog timer 80 END

Installing PC/104 Modules

This appendix gives instructions for installing PC/104 modules.

B.1 Installing PC/104 modules

The PCA-6751 Series' PC/104 connectors give you the flexibility to attach PC/104 modules.

Installing these modules on the PCA-6751 Series is quick and simple. The following steps show how to mount the PC/104 modules:

1. Remove the PCA-675 Series from your system paying particular attention 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.
