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:. 1 2 open 1 2 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.

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. 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 connector 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. 13 PCA-6781 User Manual Installation 2. 3. The modules can only fit into a socket one way. The gold pins must point down into the SODIMM socket. Chapter 2 2.6 Installing SODIMMs 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 (usually 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 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 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.
