Always use this product in a properly grounded work area and wear appropriate ESD-preventive clothing and/or accessories.

Always store this product in ESD-protective packaging when not in use.

IMPORTANT SAFE-HANDLING INFORMATION

Safe Handling Precautions

The ETX-945 contains numerous I/O connectors that connect to sensitive electronic components. This creates many opportunities for accidental damage during handling, installation and connection to other equipment. The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any vendor’s) embedded computer boards.

ESD damage – This type of damage is almost impossible to detect, because there is no visual sign of failure or damage. The symptom is that the board simply stops working, because some component becomes defective. Usually the failure can be identified and the chip can be replaced. To prevent ESD damage, always follow proper ESD-prevention practices when handling computer boards.

Damage during handling or storage – On some boards we have noticed physical damage from mishandling. A common observation is that a screwdriver slipped while installing the board, causing a gouge in the PCB surface and cutting signal traces or damaging components.

Another common observation is damaged board corners, indicating the board was dropped. This may or may not cause damage to the circuitry, depending on what is near the corner. Most of our boards are designed with at least 25 mils clearance between the board edge and any component pad, and ground / power planes are at least 20 mils from the edge to avoid possible shorting from this type of damage. However these design rules are not sufficient to prevent damage in all situations.

A third cause of failure is when a metal screwdriver tip slips, or a screw drops onto the board while it is powered on, causing a short between a power pin and a signal pin on a component. This can cause overvoltage / power supply problems described below. To avoid this type of failure, only perform assembly operations when the system is powered off.

Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for board manufacturers. However our boards are generally very dense, and if the board has components very close to the board edge, they can be damaged or even knocked off the board when the board tilts back in the rack. Diamond recommends that all our boards be stored only in individual ESD-safe packaging. If multiple boards are stored together, they should be contained in bins with dividers between boards. Do not pile boards on top of each other or cram too many boards into a small location. This can cause damage to connector pins or fragile components.

Power supply wired backwards – Our power supplies and boards are not designed to withstand a reverse power supply connection. This will destroy each IC that is connected to the power supply. In this case the board will most likely will be unrepairable and must be replaced. A chip destroyed by reverse power or by excessive power will often have a visible hole on the top or show some deformation on the top surface due to vaporization inside the package. Check twice before applying power!

3. GETTING STARTED

This section of the ETX-945 User Manual covers basic hardware setup, power connection, system boot-up, and initial software configuration. First-time ETX-945 users normally receive the product as part of one of Diamond’s Development Kits, which provide everything needed to ensure rapid application development.

ETX-945 User Manual 1.00 www.diamondsystems.com Page 10

ETX form-factor development kit: Matches the footprint of the ETX-945 and provides connectors for system I/O, CompactFlash, PC/104-Plus expansion, two additional serial ports, RS-232/422/485 buffering, a digital I/O port, and a second Ethernet LAN interface.

EPIC form-factor development kit: Provides connectors for system I/O, CompactFlash, PC/104-Plus expansion, four additional serial ports, RS-232/422/485 buffering, a second Ethernet port, a 5V/7-28V DC-to-DC power supply, and an industry-leading data acquisition subsystem.

3.1 ETX Development Kits

To facilitate evaluation and development, the ETX-945 is normally supplied pre-integrated into one of Diamond’s ETX development kits (pictured below). This approach increases project efficiency and reduces risks by providing a known good environment for rapid application development.

Diamond’s ETX development kits feature baseboards with I/O connectors for quick and easy access to nearly all system interfaces, a CompactFlash socket, and modular PC/104-Plus expansion. The kits – which include both generic models and application-oriented ETX baseboards in various form-factors – extend the ETX-945’s functionality by adding serial and LAN ports, RS-232/422/485 signal buffering, CompactFlash sockets, industryleading data acquisition I/O functions, and more. Additionally, the kits come with SO-DIMM memory, an extensive set of interface cables, drivers for Linux and Windows operation, and full documentation.

Two examples appear below.

3.2 Configuring the Hardware

Assuming you are using one of Diamond’s baseboards and heat-spreaders or heatsinks with the ETX-945, prepare the hardware as follows:

If the SO-DIMM memory module is not already installed, carefully insert it into the socket provided on the top-

side of the ETX-945 module. Refer to the specifications in the introduction of this manual for memory capacity and speed requirements.

Secure the heat-spreader (or heatsink) to the top-side of the ETX-945 module using the single short screw

provided with the heat-spreader (or heatsink), taking care to align the four corner mounting holes of the heatspreader (or heatsink) with the four corresponding standoffs on the top of the ETX-945. Note: This mounting

screw attaches to the heat-spreader (or heatsink) via a hole near the middle of ETX-945 module, and screws in from the bottom-side of the ETX module.

ETX-945 User Manual 1.00 www.diamondsystems.com Page 11

Using the four long screws provided with the heat-spreader (or heatsink), secure the heat-spreader (or

heatsink) to the corresponding standoffs located in the four corners of the top of the ETX-945 module. If the ETX module is to being installed in an enclosure, align the heat-spreader’s (or heatsink’s) corner mounting holes with corresponding hole-pattern on the enclosure before inserting and tightening the four mounting screws. Depending on the thickness of the enclosure or chassis material, slightly longer screws may be required.

Connect the baseboard to a keyboard, monitor, mouse, mass storage device, other desired peripherals, and a

source of DC power. Refer to the baseboard’s User Manual for interface cabling considerations.

Connect the baseboard to a suitable source of DC power, as described in its User Manual.

3.3 Booting the System

Power-up the VGA video monitor. Then power-up the system power supply. The ETX-945 module should begin its boot-up sequence immediately, as evidenced by BIOS messages on the connected VGA display. You can run the BIOS Setup utility and proceed to install an operating system on the boot drive just as you would on a normal desktop PC.

3.4 BIOS Setup Utility

The Award BIOS provides a Setup utility for specifying system configuration and settings. Pressing the <Del> key shortly after power is applied to the ETX-945 launches the BIOS Setup utility. Watch for the following message:

Press <DEL> to Enter Setup

The BIOS Setup utility’s main menu provides access to the following configuration and settings pages, along with several exit options. Setup categories include the following:

Standard CMOS features Advanced BIOS features Advanced chipset features Integrated peripherals PnP/PCI configuration

These are discussed briefly below.

3.4.1 Standard CMOS Features

The Standard CMOS Features function includes settings for RTC date/time initialization, IDE and floppy drive detection and configuration, default video mode, and boot error handling options. This function should be re-run if

the system’s configuration is changed, the onboard battery fails, or the configuration stored in CMOS memory is

lost or corrupt.

3.4.2 Advanced BIOS Features

The Advanced BIOS Features function provides configuration options for boot device priority, Hyper-Threading Technology, quick POST (power-on self test), and several other system parameters.

One key configuration setting is the designation of “First” and “Second” boot devices. This directs the BIOS to scan for a bootable operating system in two locations, which can be floppy, CD-ROM, hard drive, USB devices, or LAN devices. Additionally, you can specify an alternative location for the BIOS to scan, in case these are not found or do not contain a bootable OS.

Other settings available from this Setup page include boot-up NumLock status, a security password option, and selection of the system’s APIC (Advanced Programmable Interrupt Controller) mode.
