Introduction
Overview
The SeaPAC R9-7R is an application-ready platform for your next product design. The system is based on
the 400MHz Atmel AT91SAM9G45 microcontroller boasting a 32-bit ARM® instruction set for maximum
performance.
To provide the fastest time to market, the Windows CE 6.0 BSP binary and low-level drivers for system I/O
are included. Additionally, the SeaPAC R9-7R software package is equipped with the Sealevel Talos I/O
Framework, which offers a high-level object-oriented .NET Compact Framework (CF) device interface. This
interface provides an I/O point abstraction layer with built-in support for the specific needs of analog and
digital I/O such as gain control and debouncing.
The SeaPAC R9-7R is housed in a rugged enclosure suitable for panel mounting and is rated for a –30°C to
+70°C operating temperature range. The SeaPAC R9-7R is powered from your 5VDC LPS source, or optional
power supply adapter.

Software Installation
Only users running Windows 7 or newer should utilize these instructions for accessing and
installing the appropriate driver via Sealevel’s website. If you are utilizing an operating system
prior to Windows 7, please contact Sealevel by calling 864.843.4343 or emailing
[email protected] to receive access to the proper driver download and installation
instructions.
SeaPAC R9-7R Quick Start
Begin by download R9 Development for Windows. Click the download “R9 Development (Windows SDK)”
button. This will install Talos Framework, binaries, documentation, and examples on your PC (See Figure
1.)
Figure 1 - Installation Wizard
After installation, the package can be found in Windows by clicking Start All Programs Sealevel
Systems R9 Development.
The contents of the factory provided NAND Flash build will allow the R9-7R to run Windows CE 6.0 OS
when power is applied to the board.
The Talos Net Framework is also located on Sealevel’s website:
https://www.sealevel.com/support/software-talos-net-framework-windows/.

15

To avoid accidental damage, be sure to follow proper ESD procedures by grounding yourself and
the board.
Use a standard USB device cable and connect the Type B connector to the SeaPAC R9-7. Connect the
cable’s Type A connector into the host PC. (See Figure 2.)
Figure 2
You are now ready to set up a USB communication interface between the host PC and the SeaPAC R9-7.
Depending on which operating system you are using – Windows 7, Vista, or XP – the setup experience will
vary.

Windows Device Center
If your host PC is running Windows Vista or later and you are connected to the Internet, then Windows
Mobile Device Center software will install automatically. If you are not connected to the Internet but have
obtained the Windows Mobile Device Center software manually, then running their setup will achieve the
same result. (See Appendix A.)
After installation, a negotiation will begin between the PC and the SeaPAC R9-7R board and the device
center connection screen will appear. (See Figure 3.)
Figure 3. Device Center Connected
Using your mouse, select “Connect without setting up your device”. The idea is to explore the file system
on the SeaPAC R9-7R without setting up synchronization with contacts, calendar, or e-mail. Now choose
“File Management Browse the contents of your device” from the screen. (See Figure 4.)
Figure 4. Device Center File Management

This action opens a standard Windows Explorer where the default file contents of the SeaPAC R9-7R can
be read or written to. (See Figure 5.)
Figure 5 - Contents of SeaPAC R9-7
Windows ActiveSync for XP
If your host PC is running Windows XP, ActiveSync is required to establish connection to the SeaPAC R9-7.
ActiveSync differs from Windows Mobile Device Center in that having an internet connection will not
establish an automatic download and installation. For installation procedures, refer to Microsoft’s website.
(See Appendix A). After installation, a negotiation will begin between the PC and the SeaPAC R9-7R board,
and the “New Partnership” dialog will appear. (See Figure 6.)
Figure 6 - ActiveSync New Partnership Dialog

18

Using your mouse, select “No” and then select “Next”. The ActiveSync main dialog will appear. Select the
“Explore” icon. This action opens a standard Windows Explorer where the default file contents of the
SeaPAC R9-7R can be read or written. (See Figure 7.)
Figure 7 - ActiveSync Main Dialog
Connection Complete
You are now ready to set up a complete development environment for building and debugging smart
device applications and libraries. The next section guides you by example using Microsoft Visual Studio.

Programming Using The .NET Compact Framework
Application Development
Introduction
With .NET Compact Framework coupled with our Talos .NET Framework, C# and VB.NET programmers can
develop powerful embedded applications on the SeaPAC R9-7R such as mobile, robotics, home automation,
industrial, and a broad range of other embedded applications. The low cost of licensing for Windows 6.0
CE has created an ideal environment to develop a new generation of embedded products around the
SeaPAC R9-7.
Our Talos Framework allows access to the more specific I/O sections of the SeaPAC R9-7R development
board such as digital output points, CAN bus, and the serial ports. A complete list of the API documentation
can be found either in Windows by clicking Start All Programs Sealevel Systems R9 Development
Talos Documentation.html.
Writing .NET applications for the SeaPAC R9-7R is very similar to writing desktop or console applications
for XP and Vista. The only difference is the amount of resources available. Because the memory footprint
is smaller compared to a desktop computer, care should be taken where allocation of memory is concerned,
such as large object creation.
Requirements
•Visual Studio Professional 2005 or 2008
•.NET Compact Framework 3.5

Getting Started
For this demonstration, we will construct a smart device console application using Visual C#. Start Visual
Studio and select File New Project. A ‘New Project’ dialog will appear. Select a project type of Visual
C# Smart Device. Select ‘Smart Device Project’ as the Template. Make sure the combo box has .NET
Framework 3.5 selected. Type the name of the project. In this case, call it HelloWorld. (See Figure 8.)
Figure 8. Visual Studio New Project Dialog
Click the "OK" button. The next configuration screen allows you to select the type of project you are creating.
Select "Windows CE" for the target platform, .NET Compact Framework version 3.5 and select the "Console
Application" icon for the template. (See Figure 9.)
