Sections include: • Card specifications • Board layout Chapter 1 General Information 1 CHAPTER Introduction The SBC-492 is an all-in-one single board 486 computer that includes an on-board SVGA controller, with PCI-bus and ISA-bus support. It packs all the functions of an industrial computer with display capabili- ties on a single full-size card. The SBC-492 is fully PC/AT compatible, so your software will run without modifications. The SBC-492 is excellent for display-intensive applications. The on- board PCI-bus SVGA controller uses the Trident TGUI9440GUi chipset with the local PCI-bus to enable 32-bit graphic throughput at up to 33 MHz. Also built in is a standard Feature Connector. The SBC-492 supports the M-Systems DiskOnChip 2000 (optional) which is a new generation of high performance single-chip Flash Disk. It provides a Flash Disk (as a BIOS expansion) which does not require any bus, slots, or connectors. It is also the optimal solution for Single Board Computers because of its small size, easy integration, plug-and- play functionality, and its low power consumption. The DiskOnChip is available in capacities from 2MB to 72MB and fits in a standard 32-pin DIP socket. Another feature of the SBC-492 is the inclusion of a high speed, local bus IDE controller. This controller supports (through ATA PIO) mode 3 and mode 4 hard disks, enabling data transfer rates in excess of 11 MB/second. Up to four IDE devices can be connected, including large hard disks, CD-ROM drives, tape backup drives, or other IDE devices. The built-in, enhanced IDE controller provides a 4-layer, 32-bit, posted write buffer and a 4-layer, 32-bit read-prefetch buffer to boost IDE performance. Onboard features include two high speed RS-232 serial ports with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive controller. In addition to the 486's 16 KB of onchip cache memory, the SBC-492 includes an extra 128 KB of L2 onboard cache memory. If program execution is halted by a program bug or EMI, the board's watchdog timer can automatically reset the CPU or generate an interrupt. This ensures reliability in unmanned or standalone systems. 2 SBC-492 User's Manual The SBC-492 supports 5 V EDO DRAM. It also provides four 72-pin SIMM (Single In-line Memory Module) sockets for its onboard system DRAM. These sockets give you the flexibility to configure your system from 4 MB to 128 MB of DRAM using the most economical combination of SIMMs. Features • Onboard AMD DX5-133 SQFP type CPU • Fully PC/AT-compatible PCI/ISA-bus CPU card • On-board 32-bit PCI-bus SVGA controller • Built-in fast PCI enhanced IDE controller; supports four IDE devices (large hard disks, CD-ROM, tape backup, etc.) • Up to 128 MB of on-board DRAM • Supports 5 V EDO DRAM • Two high-speed serial RS-232 ports (16C550 UARTs with 16-byte FIFO); IRQ3, 4, 10, 11 can be individually selected • One enhanced bidirectional parallel port; supports SPP/EPP/ECP • Watchdog timer (2 sec ~ 128 min, 1 sec/step) • On-board keyboard and PS/2 mouse connector • Connectors for PC/104 module expansion • "Green" function; supports power management • On-board feature connector • Supports Flash BIOS, and BIOS can be upgraded easily Chapter 1 General Information 3 Specifications • CPU: AMD DX5-133 (SQFP Type) • BIOS: AMI Flash BIOS • Chipset: ALiM1487/M1489 • Bus Interface: PCI/ISA bus, PICMG 2.0 standard • Level 2 Cache: 128 KB L2 cache memory • System memory: 4MB to 128MB.

A jumper is the simplest kind of electric switch. 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 may connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 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 applications, contact your local distributor or sales represen- tative before you make any changes. 12 SBC-492 User's Manual Safety precautions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on, sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Chapter 2 Installation 13 Installing DRAM (SIMMs) The SBC-492 CPU card provides four 72-pin SIMM (Single In-line Memory Module) sockets and supports between 4 MB to 128 MB of FP RAM or EDO RAM. Installing SIMMs Note that the modules can only fit into a socket one way. 1. Insert the memory module into the socket at a moderate angle. 2. Push the module toward the vertical posts at both ends of the socket until the module is upright, and the retaining clips at both ends of the module click into place. When positioned correctly, the pins on top of the vertical posts should corre- spond to the circular holes on the ends of the module. 3. Repeat steps 1 and 2 for each module you install. Removing SIMMs If you need to remove a SIMM, follow the procedures below: 1. Supporting the SIMM with a finger, use a pen or a similarly shaped object and press one retaining clip straight down. 2. Repeat for the other side. When released, the retaining clips will push the SIMM up and out of its upright position. 3. Carefully pull the SIMM out of the socket with your fingers. 4. Repeat the above steps for each module you remove. 14 SBC-492 User's Manual SIMM Module Installation Table Modules Total SIMM 1 SIMM 2 SIMM 3 SIMM 4 Type Modules 1 S 1 S 1 S 1 S 2 S S 2 S S Single 2 S S Bank 2 S S SIMM Module 2 S S 2 S S 3 S S S 3 S S S 3 S S S 3 S S S 4 S S S S 1 D 1 D Double 1 D Bank SIMM 1 D Module 2 D D 2 D D 2 D S Mixed Single 2 D S Bank 2 S D and Double 2 D S Bank 3 D S S SIMM Modules 3 S D S S : Single Banks SIMM Module D : Double Banks SIMM Module Chapter 2 Installation 15 IDE hard drive connections You can attach four Enhanced Integrated Device Electronics (IDE) hard disk drives to the SBC-492's internal controller. The card comes with a 40-pin flat-cable piggyback cable. This cable has three identical 40-pin flat-cable connectors. Connecting the hard drive Wire number 1 on the cable is red or blue, and the other wires are gray. 1. Connect one end of the cable to PRIMARY IDE or SECOND- ARY IDE conector on the CPU card. 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 to 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.) Unlike floppy drives, you can make the connections with any of the connectors on the cable. If you install two drives, you need to set one as the master and another as the slave. You do this using jumpers on the drives. If you install just one drive, set it as the master. (See your hard drive's documentation for the setting of master/slave mode. 16 SBC-492 User's Manual Pin assignments The following table lists the pin numbers and their respective signals: IDE Connector Pin Signal Pin Signal 1 Reset 2 GND 3D7 4 D8 5D6 6 D9 7 D5 8 D10 9D4 10 D11 11 D3 12 D12 13 D2 14 D13 15 D1 16 D14 17 D0 18 D15 19 GND 20 N.C. 21 N.C, 22 GND 23 IOW 24 GND 25 IOR 26 GND 27 IORDY 28 BALE 29 N.C. 30 GND 31 IRQ 32 -I/O CS16 33 A1 34 N.C. 35 A0 36 A2 37 CS0 38 CS1 39 -ACT 40 GND IDE LED (JP2, JP3) You can connect an LED to indicate that an IDE device is in use.

Screen Control (Used to configure display drivers) b. DPMS (Used for power management configurations) c. UNinstall (Used to delete the installed TRIDENT drivers) NOTE: Different “display driver set” versions cannot be installed to the same directory name. “Display driver sets” of the same version number ( e.g. UA6.0 ) will replace the existing one. Chapter 4 SVGA Setup 61 Screen Control The Screen Control panel contains controls for setting screen resolution, color depth, font size, refresh rates. Not all combinations of screen resolution, color depth, font size and refresh rate are attainable. Color depths of 16, 256, 64K, or 16.7M colors can be selected by clicking next to the desired option. Color depth determines the number of colors that may be simultaneously displayed on the screen. The selected color depth determines the possible resolutions. Screen resolutions of 640x480, 800x600, 1024x768, 1280x1024, or 1600x1200 can be selected by clicking next to the available options. The virtual screen size is automatical- ly adjusted to be at least as large as the selected screen resolution. Available refresh rates are dependent on the selected color depth and resolution. The “Back to Default” option is used to reset the refresh rate to the factory default value. To open Screen Control, double click on its icon. The following figure shows the Screen Control interface: 62 SBC-492 User's Manual Configuring the Display Driver 1. Select the color depth first. If the current driver does not support the selected color depth, then Windows will have to be restarted. 2. Select the resolution. 3. Select the font size (if available as an option). 4. Select the refresh rate. 5. Click on OK. If the current driver does not support the selected configuration, Windows will have to be restarted. Note: Hot Key Control should be enabled before going into advanced setup. There is no virtual screen support for 16 colors. 1280x1024 is only available for 16 colors. Chapter 4 SVGA Setup 63 Advanced features (Virtual Screen Control) Virtual Screen Control Standard display resolutions are 640x480, 800x600, 1024x768, 1280x1024. The amount of display memory used depends on the selected resolution and color depth. A substantial amount of display memory is left unused for lower resolutions. The Virtual Screen features take advantage of this unused memory by “expand- ing” the display area into the off-screen area. Virtual Screen Control allows the user to make effective use of a display screen larger than the standard 640x480, 800x600 or 1024x768, and the standard resolution is the center of the screen. The user can “pan” around the larger Virtual Screen area by the use of a standard mouse or a set of “HOT KEYS.” For example, it is possible to select a resolution of 640x480 and set the Virtual Screen size to 800 x 600. Thus, the 640 x 480 screen sits at the center of a 800 x 600 matrix, and the user can “pan” through the entire 800x600 matrix in a 640x480 window, as shown below. Panning allows traversing a larger screen through a smaller window. VIRTUAL SCREEN AREA ACTUAL DISPLAY AREA 64 SBC-492 User's Manual The advanced features can be accessed by pressing + D or by clicking on the Advanced... button on the Screen Control interface.

Hot key functions are available for this feature. • Linear Frame Buffer Address: The Linear Addressing driver automatically detects the system’s memory size and sets the frame buffer to an unused area above the system memory. The Linear Frame Buffer Address setting is useful in avoiding conflicts with Windows applications, which use the same linear frame buffer address as the Display Driver. Addresses between 18 and 63 MB can be selected. If there is no conflict, the default setting is highly recommended. • Border Space: The Border Space option is used to set up a border (thickness measured in pixels) within the displayable area. The border is used as a marker for panning the screen, i.e. when the cursor hits against this border, screen panning occurs as shown below: • Pan Set Hot Key: Hot keys can be set up to pan the virtual screen left, right, up and down. The feature has to be enabled by clicking on the Enable box before hot keys can be select- ed. Once all selections are made, click on OK or press + O to exit the advanced setup. 66 SBC-492 User's Manual DPMS (Display Power Management Signaling) The POWER MANAGEMENT program is designed for energy- saving monitors that conform to the VESA Display Power Management Signaling (DPMS) standard.
