2.5 Setting Jumpers

You may configure your card to match the needs of your application by setting jump-

ers. 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.

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

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

2.6 Installing SODIMMs

1. The procedure for installing SODIMMs appears below. Please follow these

steps carefully.

2. Make sure that all power supplies to the system are switched off

3. Install the SODIMM card. Install the SODIMM so that its gold pins point down

into the SODIMM socket.

4. Slip the SODIMM into the socket at a 45 degree angle and care- fully fit the bot-

tom of the card against the connectors.

5. Gently push the SODIMM into a perpendicular position until the clips on the

ends of the SODIMM sockets snap into place.

6. Check to ensure that the SODIMM is correctly seated and all connector contacts

touch. The SODIMM should not move around in its socket.

2.7 Main Power Connector (CN16)

Supplies main power (+5 V and +12 V) to PCA-6781, and it is a 7 pins power connec-

tor.

2.8 Printer port Connector (CN3)

Normally, the printer port is used to connect the card to a printer. The PCA-6781

includes a multi-mode (SPP/EPP/ECP) printer 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 con-

nector on the other.

The printer port is designated as LPT1, and can be disabled or changed to LPT2 or

LPT3 in the system BIOS setup.

The printer port interrupt channel is designated to be IRQ7.

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

Note! The modules can only fit into a socket one way. The gold pins must

point down into the SODIMM socket.

Important! Make sure that the ATX power supply can take at least a 10 mA load on

the 5 V standby lead (5 VSB). If not, you may have difficulty powering on

your system.

Note! If your power supply doesn’t have +12 V output (+5 V only), PCA-6781

needs to go T-part number to add the components for the 5 V to 12 V

converting circuit, but LVDS and PC104 also cannot be used within +5 V

only.

PCA-6781 User Manual 14

2.9 CompactFlash Socket

The PCA-6781 provides a 50-pin socket for CompactFlash card type I/II.

2.9.1 CompactFlash (CN24)

The CompactFlash card occupies a secondary IDE channel which can be enabled/

disabled via the BIOS settings.

2.10 Floppy Connector (CN2)

You can attach up to two floppy drives to the PCA-6781’s on-board con-troller. 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 (usu-

ally used for 3.5” drives) and a printed-circuit board connector (usually used for 5.25”

drives).

2.10.1 Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into CN3. Make sure that the red wire corre-

sponds 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 connector.

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 B.

The PCA-6781 provides one IDE channels to which you can attach up to two

Enhanced Integrated Device Electronics hard disk drives or CDROM to the PCA-

6781’s internal controller. The PCA-6781'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.

2.11.1 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 CN2. Make sure that the red (or blue) wire cor-

responds 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 docu-

mentation 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.
