Start u-CenterSelect GenerationSelect COM PortU-Center Satellite StatusOpen configuration ViewSelect NMEAChange Main Talker IDSend new SettingsOpen Text ConsoleCheck Protocol

For more Details why it might be required to Change the protocol, see here related FAQ.

If your application can not handle the latest generic GNSS device ID($GN**) and requires to receives ($GP**). You can configure the built in GNSS.

On a preloaded Windows go to c:\drivers\**_GPS\GPS_UTILITY_ALL_V8.01 and Launch the uCenter Utility. (Picture 1)

Very IMPORTANT! First step, click on Receiver-> Generation and select “u-blox M8”. If following tasks are performed with wrong generation setting, the GPS receiver can be damaged. (Picture 2) 



Now click on COM port selection and choose COM3, the connection symbol will turn green and you will see available satellites in the status display on the right hand side. (Picture 3 and 4)




Choose Configuration View from the View menu. (Picture 5)


Select NMEA (NMEA Protocol) from the overview list on the left hand side, now click on the small lock symbol on the lower left corner, it will turn to an unlocked symbol. (Picture 6) 


In the center section, change Main Talker ID to “1 - GP (GPS)” than click on the “send button” on the lower left corner, take care not to accidently hit the red x, it will reset the value to its previous setting. Now click the "Save Configuration" Button in the upper toolbar. 
The line "CFG (Configutation)" will turn from gray into black and back to gray. (Picture 7 and 8)





To check if the setting was successful select Text Console from the View menu. You will see the raw NMEA sentences. The “RMC” message now should have a prefix like “$GPRMC” instead for “$GNRMC”. (Picture 9 and 10)




Now close u-center and setup your GNSS application to use COM 3 @9600 8,N,1

How long can I store my computer without loosing CMOS data?

The RTC battery is charged as soon as there is any powersupply like AC-Adapter or Vehicleadapter

  • The RTC Battery can run ~4000h a bit less than half a year.
  • It takes ~50h to fully recharge the RTC battery, because there is only a very small charging current possible.
  • If the RTC Battery is empty, the CMOS default settings are loaded. Alle BIOS settings, date & time and Passwords need to be set.

Recommended Power Settings for Windows 7

ProzessorenergieverwaltungZeitgeber zur Aktivierung zulassen

By default, Win7 does not allow the CPU to step down when using an external power supply.

The advantage of stepping down is not only that the CPU has a lower power consumption but that the computer case does not heat up so much and stays cool.

To allow CPU step down you do the following:

  1. Open the control panel and click on "Hardware and Sound".
  2. Go to "Power Options" and click on "Change battery settings".
  3. After that click for the selected power plan on "Change plan settings".
  4. Go further to "Change advances power settings".
  5. In the just opened window "Power Options", you are able to set the minimum processor state in percent under "Processor power management" > "Minimum processor state" > "Plugged in". It's recommended to use the same settings as for battery usage.

Besides the settings for CPU step down you can change the wake timers for the standby modes. The advantage is, that applications are able to wake up the system automatically from standby mode.

To enable the wake timers you follow the points 1 to 4. After that the wake timers can be enabled under "Sleep" > "Allow wake timers".

I lost the password for my Windows operating system, can I restore this?

Usually it´s not possible to restore the admin password. When the enduser gets his new roda notebook he must key in the administrator password. Some tools can be found in the internet. But they are mostly not legal. Using such tools may destroy data on the harddisk.
