Overview

The JUKI-3711P/3712 is a single board computer designed for system manufacturers, integrators, or VARs who require high performance, reliability, and quality at a reasonable price. It is available in two form factors: PCISA Bus (JUKI-3711P) and ISA Bus (JUKI-3712).

The device features a CPU fan connector and a chassis fan connector, both capable of supplying 12V/500mA to the cooling fan. These connectors include a "rotation" pin that sends the fan's rotation signal to the system, allowing the system BIOS to recognize the fan speed. It's important to note that only specified fans offer this rotation signal.

For connecting peripherals, the JUKI-3711P/3712 board is equipped with a 34-pin daisy-chain driver connector cable for floppy disk drives. It also supports two IDE (Integrated Device Electronics) hard disk drives via its PCI IDE controller, which is compatible with ATA-66 hard disk ribbon cables.

A parallel port is included, typically used for connecting a printer, and is accessed through a 26-pin flat-cable to connector CN13. The device also offers two high-speed NS16C550 compatible UARTs with Read/Receive 16-byte FIFO. COM2 provides multifunctions as RS422 (full-duplex) or RS485 (half-duplex). The RS485 automatically changes its direction based on data flow, simplifying serial port programming without special direction control.

For user input, the JUKI-3711P/3712 provides a 6-pin Mini-DIN keyboard/mouse connector. Additionally, it has two built-in USB 1.1 ports for future I/O bus expansion. Several external switches and indicators are available for monitoring and controlling the CPU board, with all functions integrated into the CN12 connector.

The JUKI-3711P/3712 is equipped with a built-in 10/100Mbps Ethernet Controller, allowing connection to a LAN via an RJ45 LAN connector. It also features a power LED connector.

The device includes a WatchDog Timer, a crucial feature for standalone systems to recover from abnormal conditions like external EMI or software bugs that cause system crashes. When the system stops working, the hardware performs a hardware reset (cold boot) to restore it to a known state. Three I/O ports control the WatchDog Timer's operation. To enable it, the user sets a time-out period (1 to 255 seconds) by sending the value to I/O port 443H, then enables it by reading data from the same port. The timer must be periodically refreshed by reading I/O port 443H within the set time-out period to prevent an unconditional reset. To disable the WatchDog timer, I/O port 843H or 043H must be read. A tolerance of at least 5% should be maintained to account for time-consuming operating system routines like disk I/O.

The JUKI-3711P/3712 also provides an E²KEY™ function for system integrators, allowing them to store ID codes, passwords, or critical data in a 1Kbit EEPROM. This nonvolatile memory ensures important data is not lost. The E²KEY™ is based on a 1Kbit EEPROM configured into 64 words (0 to 63), accessible for reading or writing at any time. A software utility, including library functions (read_e2key and write_e2key) written and compiled in C language, is provided to facilitate integration into applications.

The BIOS Setup program, built into the ROM BIOS, allows users to modify the basic system configuration. This information is stored in battery-backed CMOS RAM, retaining setup information even when power is off. The BIOS is activated upon system startup. Users can enter Setup by pressing the key immediately after powering on or when prompted during the POST (Power On Self-Test). If the prompt is missed, the system can be restarted by turning it off and on, pressing the "RESET" button, or by simultaneously pressing , , and keys.

Navigation within the Setup program is typically done using arrow keys to highlight items, to select, and to change entries, for help, and to quit. The main menu offers several setup functions and exit choices, including Standard CMOS Setup, BIOS Feature Setup, Chipset Feature Setup, Power Management Setup, PnP/PCI Configuration, Integrated Peripherals, IDE HDD Auto Detection, Supervisor/User Password, Load BIOS Defaults, Load Setup Defaults, Save & Exit Setup, and Exit Without Saving.

The Standard CMOS Setup allows for basic system configuration, including setting the system date and time, configuring IDE hard drives (Primary Master/Slave, Secondary Master/Slave), selecting floppy disk drive types, and choosing the default display device (LCD/CRT). The "Halt On" setting determines when the BIOS stops the POST process and notifies the user (e.g., on all errors, no errors, or specific errors like keyboard or diskette).

The BIOS Features Setup configures basic system operation, including default speed, boot-up sequence, keyboard operation, shadowing, and security. It allows enabling/disabling Virus Warning for IDE Hard Disk boot sector protection, which displays a warning and alarm if data is written to the boot sector or partition table. It also controls CPU Internal Cache/External Cache and CPU L2 Cache ECC Checking to optimize memory access. The Quick Power On Self Test speeds up POST by shortening or skipping some checks. Boot Sequence defines the order of devices from which the operating system is loaded. Swap Floppy Drive allows swapping logical drive assignments for two floppy drives. Boot Up Floppy Seek enables/disables disk drive seeking during boot up. Boot Up Numlock Status sets the power-on state for NumLock. IDE HDD Block Mode enables block transfer for IDE hard drives. Gate A20 Option selects whether the chipset or keyboard controller controls GateA20. Memory Parity/ECC Check is similar to GateA20 control. Typematic Rate Setting, Typematic Rate (Chars/Sec), and Typematic Delay (Msec) control keyboard key repeat behavior.

The Security Option determines if a password is required every time the system boots or only when entering Setup. If set to "System," the system will not boot and Setup access will be denied without the correct password. If set to "Setup," the system boots, but Setup access is denied without the correct password. To disable security, users can enter the password setting at the Main Menu and press without typing a password. PCI/VGA Palette Snoop is typically left disabled. OS Select For DRAM > 64MB allows selecting the operating system for systems with more than 64MB of RAM. Video BIOS Shadow and C8000-CBFFF Shadow / DC000-DFFFF Shadow determine if option ROMs (e.g., for on-board SCSI) are copied to RAM.

The Chipset Features Setup configures system features based on the installed chipset, managing bus speeds and access to system memory resources (DRAM, external cache), and coordinating ISA and PCI bus communications. Default settings are chosen for optimal operating conditions and generally should not be altered. This includes Bank 0/1 DRAM Timing (e.g., SDRAM 8/10ns, Normal, Medium, Fast, Turbo) and SDRAM Cycle Length (2, 3), which affect CPU access to DRAM. DRAM Clock selects between HOST Clk (equal to CPU HOST Clock) or HOST-33 (CPU Host Clock-33MHz). Memory Hole reserves system memory for ISA adapter ROM. System BIOS Cacheable and Video BIOS Cacheable enable caching of BIOS ROM and video BIOS for better performance, but can cause system errors if programs write to these areas. OnChip USB and USB Keyboard Support enable USB controller and keyboard support. Auto Detect DIMM/PCI Clk enables/disables automatic detection of DIMM/PCI Clock. Spread Spectrum Modulated enables/disables spread spectrum modulation.

Integrated Peripherals settings specify configurations for integrated devices. OnChip IDE Channel 0/1 enables/disables the two IDE channels. IDE Primary/Secondary Master/Slave PIO sets the PIO mode (0-4 or Auto) for each of the four IDE devices. IDE Primary/Secondary Master/Slave UDMA enables Ultra DMA/33/66 support if the hard drive and operating environment support it. Init Display First determines whether PCI Slot or on-chip VGA is activated first. KBC input clock sets the keyboard controller input clock option. Onboard FDC Controller enables/disables the floppy disk controller. Onboard Serial Port 1/Port 2 sets addresses and interrupts for serial ports. UART Mode Select chooses operation mode (IrDA, ASKIR, Normal). UART2 Duplex Mode selects full or half duplex. RxD, TxD Active selects the active level for RxD, TxD. Onboard Parallel Port sets address and interrupt for the parallel port. Parallel Port Mode selects SPP, EPP, ECP, ECP+EPP. ECP Mode Use DMA selects the DMA channel for ECP mode. EPP Mode Select selects EPP mode.

Power Management Setup configures the system for energy saving. It includes settings for HDD Power Down, Doze Mode, and Suspend Mode, with four power management selections, three having fixed mode settings. "User Defined" allows individual mode settings. "Video Off After" determines when the monitor is blanked. "Video Off Method" specifies how the monitor is blanked (V/H SYNC+Blank, Blank Screen, DPMS). "MODEM Use IRQ" determines the IRQ for the modem. HDD Power Down powers down the hard disk drive after inactivity. Doze Mode runs the CPU at a slower speed after inactivity. Suspend Mode shuts off all devices except the CPU after inactivity. PM Events are I/O events that can prevent or awaken the system from a power-saving mode.

PnP/PCI Configuration Setup configures the PCI bus system. It is recommended that only experienced users modify these settings. "PNP OS Installed" determines whether a PnP OS is installed. "Resource controlled by" allows the Award Plug and Play BIOS to automatically configure boot and Plug and Play compatible devices, or for manual resource selection. "Reset Configuration Data" allows resetting Extended System Configuration Data (ESCD) if a new add-on causes conflicts. IRQ Resources and DMA Resource allow manual assignment of interrupt and DMA channel types.

The Defaults Menu offers "Load BIOS Setup Defaults" to load BIOS default values for stable, minimal performance, and "Load Setup Defaults" to load factory settings for optimal performance.

IDE HDD Auto Detection automatically checks the correct hard disk type.

Supervisor/User Password Setting allows setting supervisor or user passwords. A supervisor can enter and change setup options, while a user can only enter but not change them. To set a password, type up to eight characters and press , then confirm. To disable a password, press without typing. When enabled, the password may be required every time Setup is entered or the system reboots, preventing unauthorized access.

Exit Selecting offers "Save & Exit Setup" to save CMOS changes and restart the system, or "Exit Without Saving" to exit Setup without saving changes, keeping previous selections in effect and restarting the computer.

The JUKI-3711P/3712 also supports an LCD-33/FP24-02 companion board, which transfers the LCD connector to a different location for easier connection. The pin definitions for CN1 and CN2 on the companion board are the same.
