USB Dongle Series Model:UD-731N 8. Application Software Introduction 8.1 u-Center The u-Center application software is provides by u-blox to support the devices with their GPS chipset built-in. This section describes the simple and quick user guides to this useful program. Please refer to the user manual of this software for more details. 8.1.
USB Dongle Series Model:UD-731N 8.1.2 Starting u-center After a successful installation, u-center will start up as shown in Figure 1: Figure 1: Start Display 8.1.3 Configuring the Serial Connection When u-center is started for the first time, the COM port needs to be initialized. u-center supports the COM-Settings listed below and all u-blox GPS receivers are pre-configured this way.
USB Dongle Series Model:UD-731N Figure 2: Start Display after a successful connection 8.1.4 Main Frame The Main Frame is the primary display screen of u-center. It displays all tool bars and some of the information provided by the GPS receiver. In the status bar, information about communication, UTC time, Operating Time, used protocol (NMEA or UBX), used file, etc. is shown.
USB Dongle Series Model:UD-731N Protocol Information: This box indicates the current message set that is being used to communicate with the GPS receiver. This can be the NMEA-0183 standard or the UBX protocol. The UBX protocol provides more extensive information with the receiver. u-center can handle both protocols.
USB Dongle Series Model:UD-731N 9. Trouble Shooting Satellite signal problem The following situations are normally if you find the GPS satellite signal is very low or absolute missing: There is something cover above. While you are in a tunnel. Inside of the building. Near by buildings. Put GPS receiver inside the car, some of the sun-control film with metal that makes microwave can not be radiate.
