6. Functional test with u-Center 6.xx
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 the 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-622MP.
1. Selecting the COM port
2. Selecting the baud rate
3. Downloading Assist GPS and updating the receiver
4. Visual display of the NMEA data
5. Configuration manager
6. NMEA/UBX message console
7. NMEA text console
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-622MP
cannot receive anything in a closed building. If the blue bars are displayed, the receiver is still
acquiring the data and verifying the received data.
