LaserLynx setup on a Tablet PC

These are Justin Kuo's notes and comments on purchasing and setting up a tablet PC to run the LaserLynx system.

Purchasing the Tablet PC

In July 2008, I purchased a used Fujitsu Stylistic ST5020D Tablet PC on eBay ($360 plus $33 S/H.) The package included the Tablet PC Tablet Dock with built-in CD-ROM drive, user manual, restore CD, drivers and appliction restore CD, System Restore DVD, Stylistic ST5000 series active pen, pen tether, battery, and AC adapter.

Here are some links to reviews and specifications:

My PC (s/n R4Y09305) has an Intel Pentium M 1.10GHz (Dothan) processor. It has a 60GB Western Digital 2.5" hard drive. The dock includes a Fujitsu CD-ROM. The display is 12.1" Transmissive Color LCD with Active Digitizer. The contrast ratio is 250 (typical), 100 (minimum) and has an 80 degree (minimum) viewing angle.

The tablet weighs 3.5 pounts and is 8.66" w x 12.77 d x 0.88" h.

It includes a PCMCIA slot, and SD (memory) slot, and a Smart Card slot.

It has an intregrated modem (RJ-11), LAN (RJ-45), IEEE 1394 (S400 4-pin), 2 USB ports, IrDA, and a 15-pin VGA connector. Wireless networking is built-in, (Atheros AR5001X). (The Bluetooth option does not appear on my PC.)

The tablet PC includes 2 memory slots for Synchronous DDR (200-pin SODIMM). Currently there is 512 MBytes in each slot for a total of 1GB of memory. The memory is expandible to 2GB. I removed the cover on the memory module. One slot contained a SAMSUNG KR 0443, PC2700S-25331-A0, M470L6524BT0-CB3 , 512MB DDR PC2700 CL2.5. The other slot contained a INFINEON, HYS64D640206GBDL-6-B,512MB DDR 333 CL2.5. I purchased two 1GB modules on eBay (4AllDeals, $93.10, plus $8.48 s/h) to replace the existing RAM.

The battery is warm-swappable. My PC included a 9-cell, 6600 mAh 10.8V battery. The battery must be charged while atached to the PC and will be 100% charged in 6 hours. I used the battery powered tablet for three hours. The remaining charge and estimated time remaining displays in the toolbar. The estimated time seems to be exagerated somewhat. Maybe, I did not set the display to dim? In the field, I may want to have an extra battery ready. I'll need to look for a charger.

There was a Fujitsu Analog Battery Charger w/AC adapter (p/n FPCBC06) that could re-charge two additional batteries. It's a bit pricey ($137). I found one on eBay that did not include the charger. I made an offer ($29.99 USD.)

The operating system is Microsoft's Windows XP Table PC Edition. I updated the OS to Windows XP Profesional Service Pack 3 Tablet PC. (s/n: 76487-OEM-0011903-00306, product key: TJY2R-4CDXB-HGQWQ-TFT69-GGB6G)

There is a fingerprint swipe sensor that seem difficult to use at first. It's supposed to make logging onto the PC as easy as wiping a finger across the sensor. I looked closely and found I had been swiping my finger 90 degress from the desired direction. There is a small raised arrow by the sensor that indicated the direction. I set up my PC to recognize my left thumb and right index finger.

I set the computer name to JKUO3 and the workgroup to ASIA. The administrator user was created automatically. I created the jkuo user. (username=jkuo, domain=jkuo3, password=********)

Getting used to the stylus is similar to using the Palm. Fortunetly, you can plug in a standard USB keyboard. Or, if you are networked you can use the Microsoft Remote Connection on a PC with a keyboard (mstsc /v:jkuo3) .

The screen used to have a screen protector on it. The glue that held it down still remains. I will need to pick up a couple sheets. I purchased a single sheet on eBay ($18 + $5 S/H.)

I purchased two replacement stylus pens with extra tips on eBay ($25 + $9 S/H.)

There is not serial port on the PC. I can use a USB to serial adapter or use a PCMCIA to serial adapter. The PCMCIA card is supposed to be more reliable than converting from USB. That may be important when connecting to a total station.

While seaching, I found recommendations on the Socket Communications brand serial I/O PC cards. (See They are a bit more expensive and they make single, dual and quad port serial adapters rugged and regular usage. The ruggedized cards have permanately attached cables while the non-ruggedized version uses dongles to connect. I purchased a used ruggedized PCMCIA card with a single serial port at Amazon ($90 plus $5 S/H.)

Installing the Software

I followed these step which I wrote in January 2008

  1. microsoft_virtual_pc_2007-setup.exe
    Go to the Microsoft web site and download the "Microsoft Virtual PC 2007" (31 MB).
  2. microsoft_device_emulator_v1.0_standalone.exe
    Go to the Microsoft web site
    and download the "" (867 KB).
  3. microsoft_efp.msi
    Go to the Microsoft web site
    and download the "efp.msi" (57 MB)
  4. microsoft_active-sync-4.5_setup.msi
    Go to the Microsoft web site Select "Worldwide English" language. Then download of the ActiveSync 4.5 update (7.52 MB)
  5. lynx_FLPPC1_20.exe
    Go to the FinishLynx web site the dowload for the Windows version of FieldLynx (1.39 MB)

Install each file in sequence and allow each installation to complete before starting the next. When prompted, use the installation defaults. If an application already exists on your PC and you are prompted with the "Change, repair or remove installation" screen, select the "repair" option. Reboot when prompted.

The FieldLynx software will install into this folder:

C:\Program Files\Lynx\FieldLynx WinCE\

Go to the Lynx site and download the "FieldLynx for Pocket PC (Windows CE), Release Notes for Version 1.20".

Open the PDF file named FieldLynx_WinCE_RN.pdf. Navigate to the page that begins with "Installing the Microsoft WinCE Emulator" (page 27). You already installed the Microsoft software so go directly to "Step 1: Start the Pocket PC emulator" and follow the rest of the instructions.

You do not need to install the any FieldLynx PPC plug-ins to run the basic FieldLynx demo. Contact Lynx System Developers, Inc. if you need the Wind Gauge, Scoreboard or LaserLynx plug-ins.


I got the emulator running but version 5 may be buggy. It did crash while adding a mark to a hammer throw event with five competitors. I had to restart with the PocketPC - Coldboot and reinstall the FieldLynx software. That took quite a bit of time. I was unable to replicate the problem.

I loaded the LaserLynx (1.11), WindGauge (1.02) and Scoreboard (1.10) plugins into the emulator. In the FieldLynx preferences, I selected the LaserLynx tab and the emulator crashed. The screen displayed the "We're Sorry... A problem has occured with gwes.exe. Please tell Microsoft abount the problem, at no cost to you. The data is used exclusively to improve products." I was able to repeat the problem.

Adding addtional memory did not help. I installed the Serial I/O card and tested the emulator. It still crashed when I got to the Laser preferences.
