2. Starting operation
2.1.
Plug the USB cable in a free USB port on your notebook etc. The NL-402U will be
recognized by your Windows operating system, which will attempt to install a driver. Abort this
process, and start “ublox5_install.exe” from the CD-ROM, or download the driver from the
Navilock website. Follow the installation instructions. After the installation is completed, re-
start your computer. Then the GPS COM port will be available in the Device Manager under
Connections. Set this port in your navigation or route planner software. Do not use another
program that accesses this port at the same time.

Flashes, with Satfix
Lights, without Satfix
3. Application environment
The NL-402U can be used as a USB GPS receiver under Windows 2000/XP/Vista. The
corresponding driver is available on the CD-ROM.
4. Functional test with u-Center 5
1. Install the u-Center software on your unit. Select the version suitable for your
system. U-Center is a pure test program and cannot be used for navigation or
orientation.
It must always be closed after the test. It blocks the COM port and does not
allow any access of the navigation or route software to the COM port. It also serves for
updating the Assist GPS data and switching to EGNOS.
If the NMEA protocol is displayed in u-Center, but you cannot find a receiver in the application
software, the connection problem is not with the receiver, but with the selected software setting.
In this case, the software manufacturer support center may be able to help you.
