Ampro Corporation P5X manual Enhanced Reliability, 100 MB/s Ethernet LAN Interface

Little Board/P5x Technical Manual

!Standard Panel Support in the ROM BIOS. The on-board video BIOS supports up to 16 of the most popular flat-panel displays, selectable from Setup.

!Optional hardware modules may be installed. These include an optional NTSC/PAL module to allow direct connection of NTSC or PAL video inputs, an optional module supporting either PanelLink or LVDS adapter modules, an optional module to convert 3.3V signals to 5.0V signals to support 5 Volt LCD Panels, and an adjustable LCD bias power supply to supply Vee for LCD panels.

100 MB/s Ethernet LAN Interface

The Ethernet subsystem is based on the Am79C972 PCnet™ Fast+ Enhanced 10/100 PCI Ethernet Controller. It fully supports IEEE 802.3 Ethernet standards — 10BaseT and 100BaseT. The Am79C972 supports an MII (Media Independent Interface) 10/100 Mb/s network port. For maximum performance, the Ethernet controller uses the PCI bus for system-side data transfers. Features of this Ethernet controller include:

!On-board DMA (programmable)

!Support for full-duplex operation

!Auto-negotiable data rate (10/100 Mb/s)

!Supports PC97, PC98, and Net PC standards

Enhanced Reliability

Reliability is especially important in embedded computer systems. Ampro, specializing in embedded system computers and peripherals, knows that embedded systems must be able to run reliably in rugged, hostile, and mission-critical environments without operator intervention. Over the years, Ampro has evolved system designs and a comprehensive testing program to ensure a reliable and stable system for harsh and demanding applications. These include:

ISO 9001 Manufacturing. Ampro is a certified ISO 9001 vendor.

Regulatory testing. Knowing that many embedded systems must qualify under EMC emissions and suscepibility testing, Ampro designs boards with careful attention to EMI issues. Boards are tested in standard enclosures to ensure that they can pass such emissions tests. Tests include European Union Directives EN55022 and EN55011 (for EMC), EN61000-4-2 (for ESD), ENV50140 (for RF Susceptibility), and EN61000-4-4 (for EFT). Conducted Emissions testing is also performed at US voltages per FCC Part 15, Subpart J (the European Union Directives are otherwise compatible with Part 15 testing).

Wide-range temperature testing. Ampro Engineering qualifies all of its designs by extensive thermal and voltage margin testing.

Voltage Reduction Technology (VRT) CPU for greater high temperature tolerance. The board uses the latest low-voltage CPU technology to extend its temperature range and reduce cooling requirements. In addition, this module utilizes active thermal monitoring features to reduce the CPU temperature.

Shock and Vibration Testing. Boards intended for use in harsh environments are tested for shock and vibration durability to MIL-STD 202F, Method 213-I, Condition A (three 50G shocks in each axis) and MIL-STD 202F, Method 214A, Table 214-I, Condition D (11.95B random vibration,
