CHAPTER 2 Installation This chapter explains the setup procedures of PCA-6780 hardware, including instructions on setting jumpers and connecting peripherals, switches and indicators. Be sure to read all safety precautions before you begin the installation procedure.
Chapter 2 Installation 2.1 Jumpers The PCA-6780 has a number of jumpers that allow you to configure your system to suit your application. The table below lists the functions of the various jumpers. Table 2.
2.2 Connectors Onboard connectors link the PCA-6780 to external devices such as hard disk drives, a keyboard, or floppy drives. The table below lists the function of each of the board’s connectors. Table 2.
2.3 Locating Connectors (component side) Figure 2.1: Jumper & Connector Locations 2.4 Locating Connectors (solder side) Figure 2.
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.
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 1 and pin 2. 3. Turn on the system. The BIOS is now reset to its default setting Table 2.
2.7 COM2 RS-232/422/485 Select (J2) Table 2.4: COM2 RS-232/422/485 Select 1-2 (default) RS-232 3-4 RS-422 5-6 RS-485 2.8 LVDS Panel Power Select (JP1) 1 2 3 1 2 3 Table 2.5: LVDS Panel Power Select Pin Function 1-2 (default) +5 V 2-3 +3.
2.9 Installing SODIMMs Notes 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.
2.11 Printer port Connector (CN4) Normally, the printer port is used to connect the card to a printer. The PCA-6780 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.
2.13 Floppy Connector (CN3) You can attach up to two floppy drives to the PCA-6780’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.
2.14 IDE Connector (CN2) The PCA-6780 provides one IDE channels to which you can attach up to two Enhanced Integrated Device Electronics hard disk drives or CDROM to the PCA-6780’s internal controller. The PCA-6780'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.
2.15 VGA/LVDS interface connections The PCA-6780’s display interface can drive conventional CRT displays and is capable of driving a wide range of LVDS flat panel displays as well. The board has two display connectors: one for standard CRT VGA monitors, and one for LVDS flat panel displays. 2.15.1 CRT display Connector (CN10) CN10 is a standard 15-pin D-SUB connector used for conventional CRT displays.
2.16 USB Connectors (CN9,CN11) The PCA-6780 board provides up to four USB (Universal Serial Bus) ports. This gives complete Plug and Play, and hot attach/detach for up to 127 external devices. The USB interfaces comply with USB specification Rev. 2.0, and are fuse protected. The USB interface is accessed through the 5 x 2-pin flat-cable connector, CN9 (USB1, 2),CN11 (USB3, 4). You will need an adapter cable if you use a standard USB connector.
2.18 HDD LED/Reset/Power Button (CN1) Next, you may want to install external switches to monitor and control the PCA-6780. These features are optional: install them only if you need them. CN1 is an 2 x 5 pin header, 180 degree, male. It provides connections for reset and power & hard disk indicator. 2.18.1 Reset (Pin7&Pin8) If you install a reset switch, it should be an open single pole switch. Momentarily pressing the switch will activate a reset. The switch should be rated for 10 mA, 5 V. 2.18.
2.19 COM port Connector (CN14,CN15) The PCA-6780 provides two COM ports (COM1: RS-232 and COM2: RS-232/422/485). CN14 supports COM1, CN15 supports COM2. And J2 is for COM2 RS-232/422/485 selection. It provides connections for serial devices (a mouse, etc.) or a communication network. You can find the pin assignments for the COM port connector in Appendix B. 2.20 MINI Keyboard Connector (CN17) The PCA-6780 board provides a keyboard connector that supports both a keyboard and a PS/2 style mouse.
