The NL-82004U can be used as a USB GNSS receiver under Windows 7/8.1/10.
5. Functional test and GNSS system selection with u-center 8.24 in Windows
5.1
. Load the u-center software from:
https://www.u-blox.com/sites/default/files/ublox-GNSS_u-
. Install the 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 routing software to the COM port. It also serves for updating the
Assist GNSS data and other configuration switches as SBAS properties.
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.
After starting the u-center software, check the functionality of your NL-82004U.
As seen below, you can set up your u-center by yourself. Everything important can be
connected and displayed immediately. The green bars at the bottom of the picture show
the reception quality at your position. If no bars are displayed, please change your
position. The NL-82004U cannot receive in a closed building. If the blue bars are
displayed, the receiver is still acquiring the data and verifying the receipt data.
