AR-B1682V Industrial Single Board ( Industrial SBC ) Pentium III CPU Card with LCD, Ethernet,SCSI Jumpers and connectors Connectors on the board link it to external devices such as hard disk drives, a keyboard, or floppy drives. In addition, the board has a num-ber of jumpers that allow you to configure your system to suit your application. The following tables list the function of each of the board’s jumpers and connectors. Jumpers Label Function Page JP6 On board standby power select W4, (JP11) Clear CMOS P1, P2, J11, JP3 COM2 RS-232/422/485 select (option) JP4 LCD driving voltage select J16, J17 DOC address select JP14 Watch dog output select JP7 Ethernet select 3 Connectors Label Function Page P3 Power on button, Reset, ALM LED, IDE LED, Key-lock, speaker, and power LED FAN CPU fan power connector POWER Power connector IDE0 IDE hard drive connector (Primary) IDE1 IDE hard drive connector (Secondary) USB USB connector FDC1 Floppy drive connector PRINT1 Parallel port connector COM1 COM1 RS-232 serial port connector COM2 COM2 RS-232/422/485 serial port connector IrDA IrDA connector KB, Mouse Keyboard and PS/2 mouse connector DOC DiskOnChip Socket VGA VGA display connector PANEL LCD display connector LAN 100Base-Tx Ethernet connector 4 Setting jumpers You can configure system 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 clip (often protected by a plastic cover) that slides over the pins to connect them. To jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3. The jumper settings are schematically depicted in this manual as follows: off on on 2-3 On board standby power select Before power on the system, have to check the power resource and choice the right “standby power select jumper”. The jumper must put on the right position otherwise system will not work. If the power comes from back-end only, the JP6 (on bard standby power select) select “3-4 on”. If the power direct connect to AR-B1682V “POWER” connect, the JP6 (on board standby power) select “3-4 off”. Normal Power Direct Connect to CPU Card 5 Clear CMOS (option I for Dallas 12887A only) When Dallas 12887A on board, you can use W4 to clear the CMOS data if necessary. To reset the CMOS data, set W4 to 1-2 closed for just a few seconds, and then move off the jumper. Clear CMOS (W4) Normal Clear CMOS W4 *default Clear CMOS (option II for Lithium Battery only) You can use JP11 to clear the CMOS when the system with Lithium Battery not Dallas 12887A. To reset the CMOS data, set JP11 to 2-3 for just a few seconds, and then move the jumper back to 1-2. Clear CMOS (JP11) Normal Clear CMOS JP11 * default 6 COM2 RS232/422/485 Select The AR-B1682V COM2 serial port can be select as RS-232 or RS-422/485 by setting P1, P2, J11 and JP3. COM2 RS-232/422/485 P1 & P2 JP11 & JP3 RS-232 *Default RS-422 *Option only RS-485 *Option only 7 LCD driving voltages select (JP4) You can select the LCD connector “PANEL” driving voltage by setting JP4. The configurations are as follows: LCD driving voltages select (JP4) 5V 3.3V JP4 * default Please contact your LCD panel supplier for makes sure a correct LCD’s working voltage. ** Any mistake will cause defect your LCD panel 8 DOC addresses select (J16, J17) The DiskOnChip 2000 occupies an 8 Kbytes window in the upper memory address range of D4000 to DC000. You should ensure this does not conflict with any other device’s memory address. J16, J17 selects the memory address window of the Flash disk. DiskOnChip 2000 memory address J16, J17 Memory Address (HEX) D4000 *default D8000 DC000 Disable These addresses might conflict with the ROM BIOS of other peripheral boards. Please select the appropriate memory address to avoid memory conflicts. 9 Watch Dog Counter Select (JP14) The watch dog counter can be selected for IRQ11, NMI or system RESET by setting the JP14. Watch Dog Counter Select (JP14) IRQ11 NMI Reset * default Ethernet Select (JP7) The RTL8139 Ethernet can be enable or disable by setting the JP7 Ethernet select (JP7) Disable Normal P7 *default 10 Front side multi-function connector (P3) The pin 1 and pin 2 of P3 is used for “power on” switch. You can short these two pins to turn on the power when the power direct connects to AR-B1682V “POWER” connector. The pin 3 and pin 4 of P3 is used for reset system. You can short these two pins to reset the system. The pin7 and pin8 of P3 is used for hard disk drive active LED. You can connect LED to these two pins to indicate HDD active. The pin 9 and pin 15 of P3 is used for speaker connector function. You can connect these two pins to the external speaker. Normal the pin 15 and pin 17 be short for internal buzzer. The pin10 and pin 12 of P3 is used for key-lock function. You can use a switch (or a lock) to disable the keyboard so the PC will not respond to any keyboard input. This is useful if you do not want anyone to change or stop a running program. The pin 14 and pin 18 (or pin 16) is used for “system on” function. You can use an LED to indicate when the CPU card is on. Pin 18, pin16 are supplying the LED’s power, and Pin14 is the ground. 11
