Other Athena II Development Kit Contents
1 8MB FlashDisk with bootable Linux
The Athena II Develop ent Kit contains a 128MB IDE FlashDisk with a bootable Linux binary. Dia ond Syste s’
Flash Linux provides a quick-boot co pact Linux environ ent based on the Slackware 2.6 kernel. It is
preconfigured for Athena II and includes our Universal Driver for the Athena II data acquisition features. Flash
Linux utilizes the Minix file syste for enhanced file protection during power loss or i proper shutdown, and the
Lilo bootloader for a quick 15 second boot ti e. The Athena II Develop ent Kit also includes a CD which provides
a binary i age of the FlashDisk files that you ay copy freely for use on Athena II SBCs.
Linux is also available on a hard drive (DSC# DK-LINUX-HD20) which includes all the features of the CD plus a
current desktop Linux distribution, including a full set of software develop ent tools ready to run. This can be used
to create an instant develop ent syste running on the target SBC, so you can develop application code and run it
i ediately on the sa e syste . Please contact your Dia ond Syste s representative for ore infor ation and
a price quotation.
ACC-IDEEXT FlashDisk Programmer Board
In the event that you wish to connect both a FlashDisk and an IDE hard disk drive or CD-ROM drive to your Athena
II board, the Athena II Develop ent Kit co es with a FlashDisk Progra er board. When connected directly to
the Athena II board, the FlashDisk occupies the pri ary IDE interface connector which does not allow for a second
drive to be attached to the pri ary IDE connector. The FlashDisk Progra er Board enables both the connection
of the FlashDisk drive and a second, slave IDE device, using either a 40-pin or 44-pin IDE connector.
PS-5V-04 AC Power Adapter
To enable your i ediate use of the Athena II board, the Athena II Develop ent Kit contains an AC Adapter with a
connector that plugs directly into the power input connector of the Athena II board. Operating with 110VAC to
240VAC input current, the AC Adapter provides sufficient current at 5VDC to power the Athena II board.
Diamond Systems Software and Documentation CD
The Athena II Develop ent Kit contains the Dia ond Syste s’ Software and Docu entation CD which provides
Athena II anuals (including this anual) and software. Software includes drivers for co ponents specific to the
Athena II board for Windows XP and Linux along with a de onstration binary of Windows CE. The CD also
contains full docu entation and software for Dia ond Syste s Universal Driver Software that supports the analog
and digital I/O capabilities of Athena II. This Universal Driver Software will operate under DOS, Windows XP/2000,
Linux, and Windows CE.

Assembling your Athena II System
Install the FlashDisk
The flashdisk odule installs directly on the IDE connector J8 and is held down with a spacer and two screws onto
a ounting hole on the board. Mounting hardware is provided in the Athena II Develop ent Kit in the packet
arked with DSC #6801008.
1. The FlashDisk odule contains a ju per to deter ine aster or slave ode. The FlashDisk ust be in
aster ode for the BIOS to auto atically detect the FlashDisk at boot ti e. Insure that the ju per is over
pins 3-4 to set aster ode (See Figure 3).
Figure 3. Layout of FlashDisk Module showing Master/Slave jumper
2. Connect round spacer (DSC# 6841002) to the FlashDisk odule using one 2-56x pan head screw and one
#2 flat washer. The spacer should be on the side of the FlashDisk odule with the fe ale IDE connector.
The washer should be on the top of the spacer. See Figure 4.
3. Attach the fe ale IDE connector on the FlashDisk to the IDE connector J8 on the Athena II board.
4. Fasten the FlashDisk in place by inserting one 2-56x pan head screw fro the solder side of the Athena II
board into the round spacer.

Install the Video Display
Athena II SBC supports both a VGA Monitor and an LVDS flat panel interface. Because of the co plexities
required in interfacing the flat panel, this FastStart Guide assu es usage of a VGA-co patible onitor.
1. Connect the video cable (DSC# 698030) provided in the Athena II Cable Kit to the VGA connector J25 on
the Athena II board.
2. Connect a VGA-co patible CRT display to the fe ale DB15 connector at the other end of the video cable.
Install the Keyboard and Mouse
The Athena II SBC supports either a legacy PS/2 keyboard and ouse interface or a USB keyboard and ouse
interface. For the PS/2 interface, connect the Breakout cable (DSC #C-PRZ-01) provided in the Athena II Cable Kit
to the Keyboard / Mouse connector J3 on the Athena II board. Connect a PS/2 keyboard to the ini-DIN connector
with KB labeled on the connector. Connect a PS/2 ouse to the ini-DIN connector with MS labeled on the
connector.
For the USB interface, connect one of the Port 0/1 USB cable (DSC# 698012) provided in the Athena II Cable Kit to
the two USB connectors (J5) on the Athena II board. Connect a USB keyboard to one of the Type A USB
connectors at the other end of the USB cable. Connect a USB ouse to one of the Type A USB connectors at the
other end of the USB cable. Connect USB ouse and keyboard the sa e way when using USB ports 2/3, except
use cable (DSC# 698032) on connector J21.
Note that a ouse is NOT required to prove correct operation of the Athena II single board co puter.

Demonstrate Data Acquisition Operation
The Dia ond Syste s’ Linux installed on the FlashDisk contains software de onstration progra s for Athena II’s
data acquisition features. You ay access the directory of these progra s by typing:
>cd /root/ATH_DEMO
In this directory resides the source code, akefile and executables of the de onstration progra s. Each
de onstration progra executable and source code is contained in its own directory. A good first de onstration
progra to run is the DSCADAutoCal progra .
The DSCADAutocal progra will calibrate the A/D data acquisition circuitry to guarantee accurate A/D input
readings. To run the progra type the following while in the de onstration progra s directory:
>./DSCADAutoCal/DSCADAutoCal
The progra will ask the user to input the following values:
Base address: This is the base address of the board deter ined is 0x280. For de onstration purposes
type 0x280.
Range to calibrate: This is the A/D odes users would typically calibrate. The odes are 0-3, 5-7. For
de onstration purposes type 255.
Range to boot: This is the A/D ode users typically boot up the board in. The odes are 0-3, 5-7. For
de onstration purposes type 0.
Once initiated the progra will calibrate the ode the user specified. The process ay take up to 15 seconds,
after which the error values will be printed on screen for each ode; values less than +-2 are within tolerance.
For ore details regarding A/D odes refer to section “Input Ranges and Resolutions” in the Athena II User’s
Manual. For ore infor ation regarding the software API and functions please refer to the DSCUD software
anual at http://docs.dia ondsyste s.co /dscud/ anual_Main+Page.ht l.
