Chapter 3 Hardware Overview This chapter discusses the chips and connectors of the module features in the following order: • CPU • Graphics • Memory • Interrupt Channel Assignments • Memory Map • I/O Address Map • Serial Port Interfaces • USB Interfaces • Keyboard and Mouse Interface • Ethernet Interface • Video Interface VGA LVDS • Power Interface • GPIO Interface • Utility Interface Power Button Reset Switch Speaker • SMBus Interface • System Fan Interfa
Chapter 3 Hardware NOTE ADLINK Technology, Inc. only supports the features/options tested and listed in this manual. The main chips used in the CoreModule 745 may provide more features or options than are listed for the CoreModule 745, but some of these features/options are not supported on the module and will not function as specified in the chip documentation. The pin-out tables only of non-standard headers and connectors are included in this chapter.
Chapter 3 Hardware Interrupt Channel Assignments The interrupt channel assignments are shown in Table 3-1. Table 3-1. Interrupt Channel Assignments Device vs IRQ No.
Chapter 3 Hardware I/O Address Map Table 3-3 shows the I/O address map. These are DOS-level addresses. The OS typically hides these physical addresses by way of memory management. Table 3-3.
Chapter 3 Hardware Serial Interfaces The CoreModule 745 provides three serial ports: two RS-232/485/422 ports (COM1 and COM2) and one RS-232 port (COM3). The SCH3114I-NU SIO contains the circuitry for all three serial ports and delivers the signals through three transceivers. The two RS-232/485/422 ports require two transceivers: one ADM213EARSZ (U11) for RS-232 signals and one LTC1334CG (U12) for RS-485/422 signals. The third serial port requires only one ADM213EARSZ transceiver (U38) for RS-232 signals.
Chapter 3 Hardware Table 3-4 defines the pins and corresponding signals for serial ports 1 and 2 headers (J3 and J4), which each consist of 10 pins, 2 rows, odd/even sequence (1, 2), and 0.079" (2mm) pitch. Table 3-4. Serial Ports 1 & 2 Interface Pin Signal Descriptions (J3 and J4) Pin # Signal DB9 # Description 1 DCD* 1 Data Carrier Detect – Indicates external serial device is detecting a carrier signal (i.e., a communication channel is currently open).
Chapter 3 Hardware Table 3-5 describes the pin signals of the serial port 3 header, which consists of 10 pins, two rows, odd/even (1, 2) pin sequence, and 0.079" (2mm) pitch. Table 3-5. Serial Port 3 Interface Pin Signal Descriptions (J5) Pin # Signal DB9 # Description 1 DCD* 1 Data Carrier Detect – Indicates external serial device is detecting a carrier signal (i.e., a communication channel is currently open).

Ethernet Interface The CoreModule 745 supports one Gigabit Ethernet interface. The Ethernet interface is implemented from the 82574IT Ethernet controller and provides one GLAN interface, which occupies PCI Express port 2.
Chapter 3 Hardware Video (VGA/LVDS) Interface The CPU provides the graphics control and video signals to the traditional glass CRT monitors and LCD flat panel displays.

Power Interface The CoreModule 745 requires one +5 volt DC power source and provides a shrouded 10-pin, right-angle header with 2 rows, odd/even pin sequence (1, 2), and 0.100" (2.
Chapter 3 Hardware User GPIO Interface The CoreModule 745 provides GPIO pins for customer use, routing the signals from the ICH8-M chipset to the J18 header. An example test application and source code reside in each BSP directory of the CoreModule 745 Support Software QuickDrive. For instructions on using the example applications, refer to the GPIO Readme in each BSP directory of the QuickDrive. For more information about the GPIO pin operation, refer to the ICH8-M datasheet at: http://www.intel.
Chapter 3 Hardware Table 3-13 describes the pin signals of the Utility interface, which uses a 5-pin, single-row header with 0.100" (2.54mm) pitch. Table 3-13. Utility Interface Pin Signals (J23) Pin # Signal Description 1 /PWR_BTN* External Power Button (Pins 1-2) 2 GND Ground 3 /RESET SW* External Reset Switch signal (Pins 2-3) 4 5V +5 Volts Power 5 SPKR_CONN Speaker Output (Pins 4-5) Note: The shaded table cells denote power or ground. The * symbol indicates the signal is Active Low.
Chapter 3 Hardware Battery Table 3-17 lists the pin signals of the External Battery Input header for backup CMOS RAM and RTC (Real Time Clock), which uses 2 pins, single row, with 0.049" (1.25mm) pitch. Table 3-17. External Battery Input Header (J6) Pin # Signal Description 1 VBAT_EXT +3.0 volts DC 2 GND Ground Note: The shaded table cells denote power or ground.
Chapter 3 Hardware Oops! Jumper (BIOS Recovery) The Oops! jumper function is provided in the event the BIOS settings you have selected prevent you from booting the system. By using the Oops! jumper you can prevent the current BIOS settings in flash from being loaded, allowing you to boot using default settings. Use a jumper to connect the DTR pin (4) to the RI pin (9) on Serial Port 1 (COM 1) prior to boot up to prevent the present BIOS settings from loading.
Chapter 3 Hardware Watchdog Timer The Watchdog Timer (WDT) restarts the system if a mishap occurs, ensuring proper start-up after the interruption. Possible problems include failure to boot properly, the application software’s loss of control, failure of an interface device, unexpected conditions on the bus, or other hardware or software malfunctions. The WDT (Watchdog Timer) can be used both during the boot process and during normal system operation.
Chapter 4 BIOS Setup Introduction This section assumes the user is familiar with general BIOS Setup. Refer to the appropriate PC reference manuals for information about the on-board ROM-BIOS software interface. If ADLINK has added to or modified the standard functions, these functions will be described. Entering BIOS Setup (Local Video Display) To enter BIOS Setup using a local video display for the CoreModule 745: 1. Turn on the display and the power supply to the CoreModule 745. 2.
Chapter 4 9. BIOS Setup Press the F4 key to enter Setup (early in the boot sequence if Quick Boot is set to [Enabled].) If Quick Boot is set to [Enabled], you may never see the screen prompt. 10. Use the key to select the screen menus listed in the Opening BIOS screen. NOTE The serial console port is not hardware protected. Diagnostic software that probes hardware addresses may cause a loss or failure of the serial console functions.
Chapter 4 BIOS Setup BIOS Setup Menus This section provides illustrations of the six main setup screens in the CoreModule 745 BIOS Setup Utility. Below each illustration is a bullet list of the screen’s submenus and setting selections. The setting selections are presented in brackets after each submenu or menu item and the optimal default settings are presented in bold. For more detailed definitions of the BIOS settings, refer to the AMIBIOS8 manual: http://www.ami.com/support/doc/MAN-EZP-80.pdf.
