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-6871 User’s Manual 12
2.6 Clear CMOS (JP1)
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

13 Chapter 2 Installation
2.7 Installing system memory (SODIMMs)
You can install anywhere from 32 to 512 MB of SDRAM into your PCI-6871 Series card. The card provides two 144-pin SODIMM sockets. Each socket accepts 32/64/128/256/512 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 PCI-6871 Series card.
Note: PCI-6871 Series cards only support SDRAM SODIMM
modules. EDO SODIMM is not supported.
2.7.1 Installing SODIMMs
Note: The modules can only fit into a socket one way. The 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 care-
fully 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 con-
nector contacts touch. The SODIMM should not move around in its
socket.
PCI-6871 User’s Manual 14
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.
Figure 2.3: SODIMM module
2.8 IDE, CDROM hard drive connector (CN1, CN7)
The PCI-6871 provides 2 IDE channels which you can attach up to four
Enhanced Integrated Device Electronics hard disk drives or CDROM to
the PCI-6871’s internal controller. The PCI-6871's IDE controller uses a
PCI interface. This advanced IDE controller supports faster data transfer,
PID mode 3, mode 4 and UDMA/100. The secondary channel supports
UDMA/33 only.
15 Chapter 2 Installation
2.8.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one of two
cables (not included in this package), depending on the drive size. 1.8"
and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connector.
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 or CN7. 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).
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.
2.9 Solid State Disk
The PCI-6871 provides a 50-pin socket for CompactFlash card type I/II.
2.9.1 CompactFlash (CN28)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
2.10 Floppy drive connector (CN6)
You can attach up to two floppy drives to the PCI-6871’s on-board controller. You can use any combination of 5.25” (360 KB and 1.2 MB) and/
or 3.5” (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy-chain drive connector cable is required for a dual-drive
system. 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 3.5” drives) and a
printed-circuit board connector (usually used for 5.25” drives).
PCI-6871 User’s Manual 16
2.10.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN6. Make sure that the
red wire corresponds to pin one on the connector.
2. Attach the appropriate connector on the other end of the cable to
the floppy drive(s). You can use only one connector in the set. The
set on the end (after the twist in the cable) connects to the A: drive.
The set in the middle connects to the B: drive.
3. If you are connecting a 5.25” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connec-
tor.
If you are connecting a 3.5” floppy drive, you may have trouble determining which pin is number one. Look for a number printed on the circuit
board indicating pin number one. In addition, the connector on the floppy
drive may have a slot. When the slot is up, pin number one should be on
the right. Check the documentation that came with the drive for more
information.
If you desire, connect the B: drive to the connectors in the middle of the
cable as described above.
In case you need to make your own cable, you can find the pin assignments for the board’s connector in Appendix C.
2.11 Parallel port connector (CN2)
Normally, the parallel port is used to connect the card to a printer. The
PCI-6871 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN2 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 Keyboard and PS/2 mouse connector (CN25)
The PCI-6871 board provides a keyboard connector that supports both a
keyboard and a PS/2 style mouse. In most cases, especially in embedded
applications, a keyboard is not used. If the keyboard is not present, the
17 Chapter 2 Installation
standard PC/AT BIOS will report an error or fail during power-on selftest (POST) after a reset. The PCI-6871’s BIOS standard setup menu
allows you to select “All, But Keyboard” under the “Halt On” selection.

2.19.1 CRT display connector (CN12)
CN12 is a standard 15-pin D-SUB connector commonly used for VGA.
The pin assignments for CRT display connector CN12 are detailed in
Appendix C.
2.19.2 Flat panel display connector (CN18)
CN18 consists of a 40-pin connector which can support a 24-bit LCD
panel. It is Hirose’s product no. DF13A-40DP-1.25 V
The PCI-6871 provides a bias control signal on CN18 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-6871’s power is
applied, the control signal is low until just after the relevant flat panel signals are present. CN18 can connect up to 24 bit TFT LCD.
2.19.3 Extension flat panel connector (CN17)
CN17 consists of a 20-pin connector which is Hirose’s product no.
DF13A-20DP-1.25V. The PCI-6871 supports a 36-bit LCD panel which
must be connected to both the CN18 (40-pin) and the CN17 (20-pin). The
pin assignments for both CN18and the CN17 can be found in Appendix C
2.19.4 LVDS LCD panel connector (CN21)
The PCI-6871 uses the VIA TwisterT chip that supports 2 channel (2 x
18 bit) LVDS LCD panel displays. Users can connect to either an 18-bit
or 36-bit LVDS LCD with CN21.
