CHAPTER 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the PCA-6753F 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-6753F.
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.

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. Caution! 2.
2.7 FDD connector (CN2) You can attach up to two floppy disk drives to the PCA-6753F'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 34-pin flat-cable connector (usually used for 3.
2.9 Flat panel display connector (CN5) CN5 consists of a 44-pin, dual-in-line header. The power supply (+12 V) for CN5 is dependant on the supply connected to the board. Therefore make sure that CN9 is connected to a +12 V power supply. The PCA-6753F provides a bias control signal on CN5 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.
2.12 PC/104 connectors (CN8) The PCA-6753F is equipped with a 16-bit ISA signal PC/104 connector for future expansion. See Appendix D for details. 2.13 AT power connector (CN9) If you prefer not to acquire power through the PCA-6753F backplane via the gold H-connectors, The big 4P power connector (CN9) also provides power input connectors for +5 V, and +12 V. 2.
2.15.1 RS-232 connection (COM1: CN12) 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. 2.15.2 RS-232/422/485 connection (COM2: CN10: RS-232; CN11: RS-422/485) COM2 is an RS-232/422/485 serial port. The specific port type is determined by jumper settings (JP6), as detailed in Chapter 1. The IRQ and address range for both ports are fixed.
2.16 ATX Feature Connector (CN13) When the PCA-6753F is used as a standalone card, the main power connector (CN9) is used. If the PCA-6753F is used with a passive backplane, the main power connector (CN9) should not be connected. This is because the card will be powered from the backplane.
2.18 Keyboard and PS/2 mouse connector (CN16) The PCA-6753F board provides a keyboard connector. A 6-pin miniDIN connector (CN16) on the card mounting bracket supports singleboard computer applications. The card comes with an adapter to convert from the 6-pin mini-DIN connector to a standard DIN connector and to a PS/2 mouse connector. 2.19 ISA gold fingers (CN17, CN18) The 16-bit ISA gold fingers are used for connecting the PCA-6753F Series to an ISA passive backplane. 2.
2.22 Reset switch (CN21, pins 6,8) If you install a reset switch, it should be a single pole switch rated at 10 mA, 5 V. Momentarily pressing the switch will activate a reset. For reset switch pin assignments, please see Appendix A. 2.23 IR connector (CN21 pins 9,11,13,15,17) 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.

The VGA configuration program will then display the following: Figure 3-2: BIOS program setup screen 2. At the prompt, type in the BIN file which supports your display. When you are sure that you have entered the file name correctly press . The screen will ask “Do you want to save?” If you wish to continue press Y.
3.4 CBROM Implementation The CBROM execute command gives users VGA BIOS setup options. The first allows users to combine the VGA BIOS into the original BIOS configuration. The second option allows users to release the VGA BIOS from the original BIOS. To implement, use the following commands: 1. CBROM 6753V110.BIN /VGA VGA.dat This command combines the VGA BIOS into the original BIOS. The file name that will be assigned to the VGA BIOS later will be VGA.dat 2. CBROM 6753V110.

"Lighting" LCDs is virtually impossible without technical expertise. Advantech provides LCD lighting and integration services to assist our customers in setting up their systems.
APPENDIX D Installing PC/104 Modules This appendix gives instructions for installing PC/104 modules.
D.1 Installing PC/104 modules The PCA-6753F PC/104 connectors give you the flexibility to attach PC/104 modules. Installing these modules on the PCA-6753F is quick and simple. The following steps show how to mount the PC/104 modules: 1. Remove the PCA-6753F 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.

APPENDIX E Programming the Watchdog Timer The PCA-6753F 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. 100 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).
