  • Page 28: System Features

    Power Supply OWER ONNECTORS Main power is applied to the EPM-5 through a 10-pin polarized connector, with mating connector Berg 69176-010 (Housing) + Berg 47715-000 (Pins). See the table below for connector pinout and page 16 for location information. Warning! To prevent severe and possibly irreparable damage to the system, it is critical that the power connectors are wired correctly.

  • Page 29: Power Requirements

    OWER EQUIREMENTS The EPM-5 requires only +5 volts (±5%) for proper operation. The voltage required for the RS-232 ports is generated with an on-board DC/DC converter. A variable low-voltage supply circuit provides power to the CPU and other on-board devices.

  • Page 30: Cmos Ram

    CMOS RAM and the Real-Time Clock. When clearing CMOS RAM: 1) Power off the EPM-5. 2) Install the jumper on V2[2-3] and leave it for four seconds. 3) Move the jumper to back to V2[1-2]. 4) Power on the EPM-5.

  • Page 31: Acpi Power Management

    System Features ACPI Power Management The EPM-5 supports the Advanced Configuration and Power Interface (ACPI) “S3 Sleeping State,” also known as “standby” or “suspend to RAM” mode. Wakeup is accomplished via a TTL-level input or pushbutton (or relay attached to the pushbutton interface). Power consumption in standby mode is under 1 watt.

  • Page 32: Wakeup

    A pushbutton or relay can be attached to connector J2 on the CBL/CBR-5010 utility board. Pin 3 is ground, and pin 4 (or pin 40 of motherboard utility connector J8) is the pushbutton input. A 3.3V or 5V TTL signal can also drive pin 4. This circuit on the EPM-5 motherboard has a 10k pull-up resistor.

  • Page 33: Interfaces And Connectors

    Interfaces and Connectors Serial Ports The EPM-5 features three on-board 16550-based serial channels located at standard PC I/O addresses. Connector J8 provides interfaces to the COM ports. See Table 6 on page 18 for COM port signal and pinout information.

  • Page 36: Usb Interface

    USB I NTERFACE Connector J8 includes interfaces for four USB ports. The USB interface on the EPM-5 is UHCI (Universal Host Controller Interface) and EHCI (Enhance Host Controller Interface) compatible, which provides a common industry software/hardware interface. There are four USB connectors on the CBL/CBR-5010 breakout board.

  • Page 37: Parallel Port

    Interfaces and Connectors Parallel Port The EPM-5 includes a standard bi-directional/EPP/ECP compatible LPT port which resides at the PC standard address of 378h. The port can be enabled or disabled and interrupt assignments can be made via CMOS Setup. The LPT mode is also set via CMOS Setup.

  • Page 38: Video Interface

    Interfaces and Connectors Video Interface An on-board video controller integrated into the chipset provides high performance video output for the EPM-5. (The EPM-5 can also be operated without video card attached. See “Console Redirection.”) ONFIGURATION The EPM-5 uses a shared-memory architecture. This allows the video controller to use 16 Mega- bytes of system DRAM for video RAM.

  • Page 39: Lvds Flat Panel Display Connector

    ISPLAY ONNECTOR The integrated LVDS Flat Panel Display in the EPM-5 is an ANSI/TIA/EIA-644-1995 specification-compliant interface. It can support up to 24 bits of RGB pixel data plus 3 bits of timing control (HSYNC/VSYNC/DE) on the 4 differential data output pairs. The LVDS clock frequency ranges from 25 MHz to 85 MHz.

  • Page 40: Compatible Lvds Panel Displays

    Compatible with DOS or Windows Generic VGA driver, but not the GX Windows driver. ONSOLE EDIRECTION The EPM-5 can be operated without using the onboard video output by redirecting the console to COM1. CMOS Setup and some operating systems such as DOS can use this console for user interaction.

  • Page 42: Ethernet Interface

    Interfaces and Connectors Ethernet Interface The EPM-5 features an on-board Ethernet controller. This controller is the Intel 82551ER Fast Ethernet controller. While this controller is not NE2000-compatible, it is widely supported. Drivers are readily available to support a variety of operating systems. See VersaLogic website for latest OS support.

  • Page 43: Audio

    Interfaces and Connectors Audio The audio interface on the EPM-5 is implemented using the Analog Devices AD1981B Audio Codec. This interface is AC ’97 2.3 compatible. Drivers are available for most Windows-based operating systems. To obtain the most current versions, consult the EPM-5 product support page at http://www.VersaLogic.com/private/pumasupport.asp.

  • Page 45: System Resources And Maps

    System Resources and Maps Memory Map The lower 1 MB memory map of the EPM-5 is arranged as shown in the following table. Various blocks of memory space between C0000h and FFFFFh can be shadowed. The CMOS setup is used to enable or disable this feature.

  • Page 46: Interrupt Configuration

    IRQ3 (B25) was bonded to PC/104 IRQ7 (B21), and PC/104 IRQ4 (B24) to PC/104 IRQ11 (D4). Though the EPM-5 is not equipped with a standard keyboard (IRQ1), floppy disk (IRQ6), or mouse (IRQ12), the BIOS infrastructure makes it appear they exist for DOS and older operating systems.
