CHAPTER 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the PCA-6740 board. You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connections.

2.3 Jumpers and connectors Connectors on the board link it to external devices such as hard disk drives, a keyboard or expansion bus connectors. In addition, the board has a number of jumpers that allow you to configure your system to suit your application.
The following table lists the connectors on the PCA-6740.
2.4 Setting jumpers 2.4.1 Introduction You may configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electrical switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, you connect the pins with the clip. To "open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3.

2.5 Watchdog timer action (JP4) When the watchdog timer activates (CPU processing has come to a halt), it can reset the system or generate an interrupt on IRQ11.
The following sections tell how to make each connection. In most cases, you will simply need to connect a standard cable. All of the connector pin assignments are shown in Appendix A. Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on. Sensitive electronic components can be damaged by a sudden rush of power. Only experienced electronics personnel should open the PC chassis.
2.7 FDD connector (CN2) You can attach up to two floppy disk drives to the PCA-6740's onboard controller. You can use any combination of 5.25" (360 KB/ 1.2 MB) and/or 3.5" (720 KB/1.44/2.88 MB) drives. The card comes with a 34-pin daisy-chain drive connector cable. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34pin flat-cable connector (usually used for 3.
2.9 Flat panel display connector (CN4) CN4 consists of a 44-pin, dual-in-line header. The power supply (+12 V) for CN4 is dependant on the supply connected to the board. Therefore make sure that CN17 is connected to a +12 V power supply. The PCA-6740 provides a bias control signal on CN4 which can be used to control the LCD bias voltage. It is recommended that the LCD bias voltage not be applied to the panel until the logic supply voltage (+5 V or +3.3 V) and panel video signals are stable.
2.13 ATX Feature Connector (CN7) When the PCA-6740 is used as a standalone card, the main power connector (CN7) is used. If the PCA-6740 is used with a passive backplane, the main power connector (CN7) should not be connected. This is because the card will be powered from the backplane.
2.15 PC/104 connectors (CN10) The PCA-6740 is equipped with a 16-bit ISA signal PC/104 connector for future expansion. See Appendix D for details. 2.16 Ethernet connector (CN11) The PCA-6740 is equipped with a high performance 32-bit PCI-bus Fast Ethernet interface which is fully compliant with IEEE 802.3u 10/100Base-T specifications. It is supported by all major network operating systems. The medium type can be configured via the rset8139.EXE program included on the utility disk.
Table 2-3: Serial port connections (COM1, COM2) Connector Function COM1,3*,4* RS-232 COM2 RS-232/422/485 2.17.1 RS-232 connection (COM1:CN15) 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. 2.17.2 RS-232/422/485 connection (COM2: CN10: RS-232; CN11: RS-422/485) COM2 is an RS-232/422/485 serial port.
2.18 Internal keyboard connector (CN16) In addition to the PS/2 mouse/keyboard connector, an additional external keyboard connector is provided. For external keyboard pin assignments, see Appendix A. 2.19 AT power connector (CN17) If you prefer not to acquire power through the PCA-6740 backplane via the gold H-connectors, The big 4P power connector (CN17) also provides power input connectors for +5 V, and +12 V. 2.
CHAPTER 3 Award BIOS Setup This chapter describes how to set BIOS configuration data.
3.1 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.
3.2 Award BIOS setup Award’s BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS RAM so that it retains the Setup information when the power is turned off. 3.2.1 Entering setup Power on the computer and press immediately. This will allow you to enter Setup.
3.2.2 Standard CMOS Features Setup When you choose the Standard CMOS Features option from the Initial Setup screen menu, the screen shown below is displayed. This standard Setup Menu allows users to configure system components such as date, time, hard disk drive, floppy drive and display. Once a field is highlighted, on-line help information is displayed in the left bottom of the Menu screen.

3.2.8 Set Password To enable the password feature, you must first select either Setup or System under the Security Option in the Advanced BIOS Features Setup. To change the password, choose the Set Password option from the Initial Setup Screen menu and press . 1. If the CMOS is bad or this option has never been used, a default password is stored in the ROM. The screen will display the following messages: Enter Password: Press . 2.
Figure 3-8: Set Password Screen 3.2.9 Save & Exit Setup If you select this option and press , the values entered in the setup utilities will be recorded in the chipset’s CMOS memory. The microprocessor will check this every time you turn your system on and compare this to what it finds as it checks the system. This record is required for the system to operate.
3.2.10 Exit without saving Selecting this option and pressing lets you exit the Setup program without recording any new values or changing old ones.

APPENDIX E Programming the Watchdog Timer The PCA-6740 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.
E.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. 120 Data Time Interval 01 1 sec. 02 2 sec. 03 3 sec. 04 4 sec. • • • • • • 3E 62 sec.
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).
