WARNING: ESD-Sensitive Electronic Equipment!
Observe ESD-safe handling procedures when working with this product.
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

Aurora 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!

Bent connector pins – This type of problem is often only a cosmetic issue and is easily fixed by bending the pins
back to their proper shape one at a time with needle-nose pliers. This situation can occur when pulling a ribbon
cable off of a pin header. Note: If the pins are bent too severely, bending them back can cause them to weaken
unacceptably or even break, and the connector must be replaced.

1.2 SUMIT Socket Resources

Aurora’s SUMIT-A expansion socket provides the host interface resource support indicated in the table below. For
further details on the SUMIT expansion standard, visit SFF-SIG.org/sumit.html.

1.3 Software Compatibility

Aurora is compatible with Linux, Windows XP, and Windows Embedded Standard. All necessary drivers for these
operating systems are provided with the product.

1.4 Thermal Considerations and Heatspreader

All models of Aurora are specified for a -40oC to +80oC operating range, the temperature being measured at the
outside surface of the heatspreader. Diamond provides a heatspreader attached to the Aurora single board
computer as a conductive cooled thermal layer. However, this heatspreader by itself does not constitute the
complete thermal solution necessary for any specific implementation, but provides a common interface between
the single board computer and the customer’s implementation-specific thermal solution.

The outside surface of the Aurora heatspreader must be kept at a temperature not to exceed +80oC. If your
environment causes the temperature on the outside surface of the heatspreader to exceed this temperature, you
are responsible for removing the additional heat from the system through either an additional passive thermal
solution or fan solution.

Aurora’s integrated heatspreader makes thermal contact with the heat generating components and provides a flat
surface on the bottom of the assembly for mating to the system enclosure. This technique facilitates efficient
removal of heat from the SBC without the need for a fan. Four mounting holes on the bottom of the conduction
cooled heatspreader are provided to mount Aurora in an enclosure or to a bulkhead. These mounting holes are
#6-32 threaded holes on 2.8" centers.

Aurora User Manual Rev A6 www.diamondsystems.com Page 15

Caution! Be sure the PS-5V-01 AC power adapter is disconnected from

its AC power source prior to performing the following step…

3.2 System Setup

This section outlines a simple process for preparing Aurora for first-time operation using the Aurora Development

Kit. Additional details regarding Aurora’s interface functions and connections may be found in Section 4 of this

document (“Interface Connector Details”).

3.2.1 Keyboard and Mouse

Aurora supports operation using PS/2-based keyboard and mouse devices. Plug the keyboard and mouse cable,
6981301, from the Aurora Cable Kit into the connector KBMS1 on Aurora. Then plug the keyboard and mouse
into the mating connectors on the Aurora interface cables.

3.2.2 USB Flashdisk Socket

Aurora provides a location for on-board installation of an optional USB flashdisk on connector USB3. Plug the
USB flashdisk module, 8890300, in the Development Kit into connector USB3 on Aurora. Remove the screw from
the mounting stand-off before installing the flashdisk. Secure the flashdisk to Aurora with the screw once the
flashdisk is installed.

3.2.3 Mass Storage Devices

If desired, connect SATA hard drives to Aurora by connecting a USB cable, part number 6981082, to connector
USB1 and then to the SATA drive. Aurora can operate with a combination of SATA and CD-ROM drives, and can
boot from either of them.

3.2.4 Connecting Power

Connect cable 6981037 to the PS-5V-01 AC power adapter. Connect the other end of the 6981037 cable to
connector PWR1 on the Aurora SBC.

3.2.5 Display

Aurora provides interfaces for both LVDS flat panel displays and SDVO output. VGA CRTs can also be used via
an external SDVO to VGA converter. This quick-start process assumes you are using the external VGA converter
(number ACC-VGA-03) supplied with the development kit.

Install the I/O board provided in the ACC-VGA-03 kit on top of Aurora, aligning the PC/104 and SUMIT-A
connectors. Connect the VGA cable supplied in the ACC-VGA-03 between the VGA connector on the I/O board
and a VGA-compatible display.

3.2.6 Installing Aurora in an Enclosure (optional)

Install the Aurora single board computer in an enclosure that has an appropriate mounting-hole pattern (2.8”
square).

Aurora’s heatspreader has four #6-32 threaded holes on 2.8” centers for mounting. Select four #6-32 threaded
screws of the proper length and head type to work with your enclosure. Allow a minimum of 0.25” and maximum
of 0.40” screw length for insertion into Aurora’s heatspreader. The total screw length will depend on the thickness
of your enclosure wall.

Aurora User Manual Rev A6 www.diamondsystems.com Page 16

3.3 Booting the System

Power-up the VGA video monitor. Then plug the PS-5V-01 AC power adapter to an AC outlet. Aurora 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.

3.3.1 BIOS Setup

Aurora’s BIOS provides a wide range of configuration options. When you power up Aurora for the first time, you

should immediately enter the BIOS “Setup” utility in order to adjust BIOS settings to match your system’s

peripheral devices and other requirements, and to configure various other hardware and software parameters.
Options configurable via Setup typically include:

Number and type of mass storage devices
Boot device priority
Video display type and resolution
IDA, SATA, serial, and parallel interface modes and protocols
PCI and PnP configuration
Power management setup
Automatic power-up after LAN connection, RTC alarm, power resumption, etc.
System monitoring and security functions

3.3.2 Operating System Drivers

Aurora will boot and run a Linux 2.6 operating system from the USB flashdisk. Aurora should now be fully
operational.

If you desire to run a different operating system, depending on the operating system to be installed, it may be
necessary to install software drivers for on-board interface controllers. Drivers for Windows XP, XPe, and Linux

2.6, if required, are included on the Software and Documentation CD that is included in the Aurora Development
Kit. This software is also available for download from the Aurora page at Diamond’s website,

4.5 Serial Ports (COM1, COM2)

These connectors provide access to the board's four serial ports. COM1 provides access to Port1 and Port2.
COM2 provides access to Port3 and Port4.

Ports 1 and 2 are fixed for RS-232 only, while ports 3 and 4 may be jumper-configured for RS-232, RS-422, or
RS-485 protocols. The connector pinout changes depending on the selected protocol. Aurora can be custom­ordered preconfigured for a selected protocol; it is also possible to order a fixed configuration with soldered-on
zero ohm resistors, so no jumpers are used.

4.8 PC/104 (ISA) Expansion Bus (PC104_1)

The PC/104 bus is essentially identical to the ISA Bus except for the physical design. It specifies two pin and
socket connectors for the bus signals. A 64-pin header incorporates the 62-pin 8-bit bus connector signals, and a
40-pin header incorporates the 36-pin 16-bit bus connector signals. The additional pins on the PC/104 connectors
are used as ground or key pins. The female sockets on the top of the board enable stacking another PC/104
board on top of the board, while the male pins on the bottom enable the board to plug into another board below it.

In the pinout figures below, the tops correspond to the left edge of the connector when the board is viewed from
the primary side (side with the female end of the PC/104 connector) and the board is oriented so that the PC/104
connectors are along the bottom edge of the board.

Note: For more information on the PC/104 specification, visit the PC/104 Embedded Consortium website, at

http://www.pc104.org.

Aurora User Manual Rev A6 www.diamondsystems.com Page 29

6. BIOS

Aurora’s BIOS provides access to many valuable features. These instructions show how to enter the BIOS, set up
features, and restore the BIOS to its default settings.

6.1 Entering the BIOS

The BIOS may be entered during startup by pressing the DEL key on an attached keyboard or pressing F4 if
using console redirection. Press the key repeatedly right after power-on or reset until the BIOS screen appears.

After a certain amount of time during startup, the BIOS will ignore the DEL or F4 key. If you wait too long and the
system does not respond, simply reset the system (or power down) and try again.

6.2 Restoring Default BIOS Settings

In order to load the default BIOS settings, turn off the system and install a jumper on pins 2-3 of jumper block
JBAT1, located on the bottom right corner of the board. This will clear CMOS and reset the BIOS to the default
settings. After three seconds put the jumper back to position 1-2 and turn the system on.

On the first screen after booting up, the user will be asked to press F1 to run SETUP, or F2 to load the defaults.

6.3 Setting the Date and Time

The date and time are set in the BIOS. Select Main menu, then enter the date and time at the bottom of the
screen. This screen also displays the CPU speed and memory capacity of the board.

6.4 ISA Bus IRQ Reservation

An ISA bus IRQ must be reserved in the BIOS in order to be used by the on-board ISA bus circuits or an installed
PC/104 module. To reserve an IRQ, go to the PCIPnP menu and scroll down to the IRQ list at the bottom. The
default settings are IRQ15 reserved with the remaining IRQs available.

6.5 Boot Priority

To select Boot devices and set their priority, go to the Boot -> Boot device priority menu and select the first boot
device from the list.

Upon clicking on the first boot device, a window with the available devices will open. The user can select any of
the devices as the first boot device.

The devices can be a SATA HDD, a network drive, or a USB device.
The USB device present in this list is the first Drive defined in the “USB Drives” Menu.
Here are the steps to select a USB drive to boot from:

1. Boot-> USB Drives -> 1st Drive -> ( select a USB device from the list)

2. Boot->Boot Device Priority-> 1st Boot device ( select the USB device which has been defines in line 1)

In this way, the system will try to boot from the USB device. The same procedure applies for other boot devices
(2nd, 3rd,…).

6.6 Chipset

The chipset menu is provided to define and change the North / South Bridge options such as Graphic Adapter
Modes, flat panel type (default is 800x600), and enable/disable on-board PCI3 line and Ethernet adapter.

By default, both PCIe and LAN controllers are enabled. This can be changed in the South Bridge menu.

Aurora User Manual Rev A6 www.diamondsystems.com Page 30

6.7 Super I/O Configuration

This is to set the address/IRQ of the four serial ports. COM3 and COM4 are capable of RS-232/422/485
protocols; whereas COM1 and COM2 can only be set to RS-232.

6.8 Console Redirection

In the advanced menu, the user can select any of the serial ports for console redirection with different speeds
ranging from 115200bps to 9600bps as follows.

Advanced - Remote Access Configuration - Disabled (Default)
When set to Enabled, the console re-direction is activated on COM1 by default at 115200,n,8,1 communication

settings. The remote access configuration can be enabled on any of the four COM ports. Baud rates supported
are 115200 (default when enabled), 57600, 38400, 19200 and 9600.

When set to Enabled, the BIOS can be accessed by pressing F4 on the remote keyboard. BBS POPUP can be
accessed by pressing F3 on that remote keyboard.

7. DIGITAL I/O LINES

Aurora has eight digital I/O lines found on connector GPIO_P1. This connector has one pin for each line plus an
External Reset Input and Ground line. Please note that the digital I/O lines on Aurora are not 5V tolerant.

7.1 DIO Registers

Aurora’s digital I/O lines are associated with a set of registers as shown in the following table.

7.2 DIO Programming

To use Aurora’s digital I/O lines, first configure the desired directions by writing the appropriate configuration

value to the digital I/O lines’ register. Then read or write data on the digital I/O lines’ level register. All I/O lines

are in read mode on power-up or after a board reset. Sample code for reading and writing to the digital I/O lines
follows.

8. WATCHDOG TIMER

One watchdog timer is provided for system control with a WDTOUT# signal. The base address for the watchdog
timer is 0x300. The watchdog timer has a default hardware setting defined at power on which sets the timer to 10
seconds. The interval also can be programmed by registers for a 10ms, 1s or 1 minute timeout. Upon timeout,
the timeout trigger pulls the tri-state signal, WDTOUT#, low.

Ruggedized RSODIMM™ Module

9.4 Flashdisk Installation

Installing a USB flashdisk module on Aurora is straightforward using the following steps.

1. Ensure power is disconnected from Aurora.

2. Remove the screw from the standoff located between the flashdisk connector, USB3, and the PC/104
connector.

3. Align the flashdisk so that its female connector aligns with the pins on connector USB3 and the
mounting hole aligns above the standoff.

4. Press the flashdisk downward onto connector USB3.

5. Reinstall the screw, securing the flashdisk module to Aurora.

10. RUGGEDIZED RSODIMM™ SO-DIMM MODULES

Aurora comes with ruggedized RSODIMM™ SO-DIMM SDRAM modules for improved performance in high shock
and vibration environments. These modules securely affix to the Aurora single board computer through a pair of
standoffs and screws. This innovative design ensures that the SO-DIMM module remains fixed in place and
cannot back out of its socket.

These ruggedized SO-DIMM modules are identical in function to the standard SO-DIMMs, but have an extended
PCB with two mounting holes that attach to Aurora as can be seen below.

10.1 Models and Capacities

10.2 SO-DIMM Memory Installation

Installing a SO-DIMM memory module on Aurora is straightforward using the following steps. These steps
assume you are installing a rugged memory SO-DIMM from Diamond Systems. If no, please disregard steps 2
and 6.

1. Ensure power is disconnected from Aurora.

2. Remove the two screws from the two standoffs located between the SO-DIMM connector and the
edge of the board.

3. Insert the SO-DIMM module into the socket at a slight angle, approximately 30 degrees. The socket
and module are both keyed, which means the module can be installed one way only.

4. To seat the module into the socket, apply firm, even pressure to each end of the module until you feel
it slip down into the socket.

5. With the module properly seated in the socket, rotate the module downward. Continue pressing
downward until the clips at each end of the socket lock into position.

6. Reinstall the two screws into the standoffs, securing the SO-DIMM to Aurora.

11.2 Outside Facing I/O Connectors

These connectors are on the top side of the board. They face out through the enclosure front panel. All
connectors must be compatible with the specified distance of 7mm between the top panel and the panel I/O
board.

11.2.1 Input Power (J1)

The input power connector, J1, is Molex part number 39-30-2045 or equivalent. Each pin has a 6A or greater
current carrying capacity.

Input power may be supplied either as +5VDC, +5V/+12V DC or as Vin. The +5V and +12V are intended to be
switched directly to the PC/104 bus power pins via the external power switch. The Vin is intended to be switched
to an auxiliary connector on the back side of the board which is used to connect to a DC/DC power supply. The
output of the DC/DC power supply is then fed either to the PC/104 bus power pins (if the power supply is on the
PC/104 bus) or back to the panel board and then to the Aurora SBC through the +5V pins on the SBC mating
power input connector.

11.2.2 Ethernet (J23 Ethernet)

The Ethernet connector, J23, is a vertical metal-shielded RJ-45 jack with industry standard pinout for gigabit
Ethernet.

Proper isolation must be maintained on all Ethernet signal routing to meet industry standard signal isolation
specifications. No ground or power plane should be above or underneath these signals.

11.2.3 VGA (VGA)

The VGA connector is standard vertical DD15 female connector with industry standard VGA pinout. It has 4-40
thread inserts and hex screwlocks. The signals come from the SBC mating VGA connector.

11.2.4 USB (USB1, USB2, USB3, USB4)

The USB connectors are four vertical metal shrouded type A connectors with industry standard pinout for USB.
The signals come from the two SBC mating USB connectors.

11.2.5 PS/2 Keyboard and Mouse (J25 Keyboard, J26 Mouse)

The PS/2 connectors are two vertical Mini-DIN-6 connectors with industry standard pinout for PS/2 keyboard and
mouse. The signals come from the SBC mating PS/2 connector.

11.2.6 Serial Ports (COM1, COM2, COM3, COM4)

The serial port connectors are four vertical DB9 male connectors. They have 4-40 thread inserts and hex
screwlocks. Ports 1-4 signals come from the two 20-pin SBC serial port connectors and each port connector uses
the pinout shown below. To prevent EMI problems, ferrite bead packs are installed on the panel I/O board on the
signal and ground connections to the DB9 connectors.

Aurora User Manual Rev A6 www.diamondsystems.com Page 41

11.3 Power Routing

There are two paths for input power. A +5VDC source, a +5V/12V source, or a variable input voltage source can
be connected to the Aurora SBC power connector, or it can be connected to an external power supply source that
provides +5V and +12V power to the PC/104 bus in the stack.

The panel I/O board also provides a path for optional +12VDC output from a power supply to the Aurora SBC
through the pin socket.

The panel I/O board contains two green LEDs which are connected to the +5VDC and +12V/VIN signals to
indicate power status.

There is also a 3.5V lithium battery mounted on the board to provide standby voltage to the CMOS/RTC unit on
Aurora. The battery is a LTC-7PN or equivalent type with 4 pins and is soldered on the panel board without a
socket for rugged-environment applications.

The schematic in Figure 7 indicates the power routing between the input power connector and Aurora through the
panel I/O board. Power may be provided in several methods:

1. +5V (and +12V) in from the input power connector directly to the panel I/O board, using either the front
panel switch or a direct connection, and then to the Aurora SBC through the input connector (PWR1).

2. Vin (+8-30VDC) from the input power connector to a connector leading to an internal DC/DC power
supply, whose output is driven directly onto the PC/104 bus using the PC/104 bus connectors on the
DC/DC power supply. The Vin may be routed to the power supply connector either through the front panel
switch or through a direct connection.

The +5V source is connected to the board by a 1x4 0.200” locking connector, routed through a 1x2 0.156” pitch
friction lock connector for a front panel switch and then to a pin socket on the bottom side that mates with Aurora.
If +12V is also needed it is connected to the board by the same 1x4 connector, routed through a separate 1x2

0.156” friction lock connector for a front panel switch and then to the same pin socket on the bottom side that
mates with Aurora. In this case the switch would be DPDT type instead of the SPDT type used by 5V or 12V only.
The switch connectors can be bypassed with jumpers if desired.

The variable input voltage source is routed through another 1x2 .1” pitch friction lock connector for a front panel

switch and then to a separate 1x2 0.156” pitch or 1x2 0.100” pitch friction lock connector for connection to a

DC/DC power supply mounted inside the enclosure. The +5VDC output of this DC/DC power supply then has two
paths to Aurora: (1) It can connect directly to the PC/104 bus of the system, if the power supply is mounted on the
bus; or (2) it can be routed back to the panel I/O board with another connector and then to Aurora through the
panel I/O board’s pin socket connection.

The switch bypass jumpers are 0-ohm ¼ watt T/H resistors. To use the panel power switch, the resistor is cut
away, opening the circuit.

The +12 input option jumper is used to enable +12V to be supplied through the Vin pin on the front panel
connector. In this case both +5V and +12V would be supplied through the front panel connector. This jumper is a
0-ohm ¼ watt T/H resistor.
