! 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 mod ule sup porting

either PanelLink or LVDS adapter modules, an optional module to conver t 3.3V signals to 5.0V

signals to support 5 Volt LCD Panels, and an adjustable LCD bias power supply to su pply Ve e

for LCD panels.

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, kno ws that e mbedd ed sy stems m ust be able to ru n

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 p ass such emissio ns tests. Te sts inclu de

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 pe rforme d

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 sh ocks in

each axis) and MIL-STD 202F, Method 214A, Table 214-I, Condition D (11.95B random vibration,
