2.5 Setting Jumpers

You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir­cuit. 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. In this case you would connect either pins 1 and 2, or 2 and 3.

open closed closed 2-3

The jumper settings are schematically depicted in this manual as follows:.

open closed closed 2-3

A pair of needle-nose pliers may be helpful when working with 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.

Generally, you simply need a standard cable to make most connections.

PCI-6872 User’s Manual 12

2.6 Clear CMOS (J1)

Warning! To avoid damaging the computer, always turn

off the power supply before setting “Clear
CMOS.” Before turning on the power supply,
set the jumper back to “3.0 V Battery On.”

This jumper is used to erase CMOS data and reset system BIOS informa­tion.

The procedure for clearing CMOS is:

1. Turn off the system.

2. Short pin 2 and pin 3.

3. Return jumper to pins 1 and 2.

4. Turn on the system. The BIOS is now reset to its default setting

2.8 Watchdog timer configuration

An on-board 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 one jumper and running the control software (refer to Appendix
A).

2.8.1 Watchdog timer output option (J2)

When the watchdog timer activates (CPU processing has come to a halt),
it can reset the system or generate an interrupt on IRQ11. This can be set
via setting J2 as shown below:

Table 2.5: Watchdog timer output option (J2)

*System reset IRQ 11

* default setting

PCI-6872 User’s Manual 14

2.9 Installing DIMMs

The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den­sity.

1. Make sure that the two handles of the DIMM socket are in the

“open” position. i.e. The handles remain leaning outward.

2. Slowly slide the DIMM module along the plastic guides on both

ends of the socket.

3. Press the DIMM module right down into the socket, until you hear

a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.

To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.

2.10 ATX power control connector (CN20,CN21)

2.10.1 ATX feature connector (CN20) and soft power

switch connector (CN21)

The PCI-6872 can support an advanced soft power switch function, if an
ATX power supply is used. To enable the soft power switch function:

1. Get the specially designed ATX-to-EBX power cable

(PCI-6872 optional item, part no. 1703200100)

2. Connect the 3-pin plug of the cable to CN20 (ATX feature connec-

tor).

3. Connect the power on/off button to CN21. (A momentary type of

button should be used.)

Important Make sure that the ATX power supply can take

at least a 10 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty power­ing on your system.

PCI-6872 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN4 and a 26-pin flat-cable connector. You will need an adapter cable
if you use a traditional DB-25 connector. The adapter cable has a 26-pin
connector on one end, and a DB-25 connector on the other.

The parallel port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.

The parallel port interrupt channel is designated to be IRQ7.

You can select ECP/EPP DMA channel via BIOS setup.

2.12 CompactFlash Card connector

The PCI-6872 provides a 50-pin socket for CompactFlash card type I/II.

2.12.1 CompactFlash (CN5)

The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.

2.13 Floppy drive connector (CN3)

You can attach one 3.5" floppy drive to the the PCI-6872'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 3.5" 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 3.5" 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 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.

2.14 IDE connector(CN1,CN2)

The PCI-6872 provides two IDE channel to which you can attach up to
four Enhanced Integrated Device Electronics hard disk drives or
CDROM to the PCI-6872’s internal controller. The PCI-6872's IDE con­troller uses a PCI interface. This advanced IDE controller supports faster
data transfer, PIO Mode 3 or Mode 4, UDMA 33/66/100 mode.

2.14.1 Connecting the hard drive

Connecting drives is done in a daisy-chain fashion. The cable depending
on the drive size. 1 x 40-pin flat cable(p/n: 1701400452) is packing in
PCI-6872's package.

Wire number 1 on the cable is red or blue, and the other wires are gray.

1. Connect one end of the cable to CN1,CN2. 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).

17 Chapter 2 Installation

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.
(See your hard drive’s documentation for the location of the con­nector.)

If desired, connect a second drive as described above.

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 only one
drive, set it as the master.

2.15 VGA/LCD interface connections

The PCI-6872’s display interface can drive conventional CRT displays
and is capable of driving a wide range of flat panel displays as well,
including passive LCD and active LCD displays. The board has two dis­play connectors: one for standard CRT VGA monitors, and one for flat
panel displays.

2.15.1 CRT display connector (CN7)

CN7 is a standard 15-pin D-SUB connector commonly used for VGA.

Pin assignments for CRT display connector CN7 are detailed in Appendix
C

2.15.2 Flat panel display connector (CN22)

CN22 consists of a 40-pin connector which can support an 18-bit LCD
panel. It is Hirose’s product no. DF13A-40DP-1.25 V.

The PCI-6872 provides a bias control signal on CN22 that 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. Under normal operation, the
control signal (ENAVEE) is active high. When the PCI-6872’s power is
applied, the control signal is low until just after the relevant flat panel sig­nals are present. CN22 can connect up to 18 bit TFT LCD

.

2.15.3 Extension flat panel connector(CN23)

CN23 consists of a 20-pin connector which is Hirose's product no. DF13­20DP-1.25V. The PCI-6872 supports a 36-bit LCD panel which must be
connected to both the CN22(40-pin) and CN23 (20-pin). The pin assign­ments for both CN22 and CN23 can be found in Appendix C.
