# ZED-F9P RTK configuration

> Whether it is to configure your OEM ZED-F9P RTK device as a base or a rover, the approach is the same. Only the configuration file will differ.

{% hint style="info" %}
Download configuration files for Base and Rover [here](https://github.com/drotek/RTK-ZED-F9P-GNSS/raw/master/RTK-ZED-F9P-GNSS-master%20V2%20september.zip).

First things first, download u-center by clicking [here.](https://www.u-blox.com/en/product/u-center) Then scroll-down and click on the “u-center for Windows, 22.xx” tab. Once the zip installer is downloaded, double-click on the zip, then double-click on the “u-center\_v22.xx.exe”. Select your prefered language and follow the procedure: Next click ‘OK’, ‘Next’, ‘accept’, ‘Next’, ‘Install’.

To begin, connect your GNSS device to a computer using a USB micro cable.

Now start the U-blox “u-center” software. Then, on the top left corner of the screen, left-click on the reversed tiny black triangle to select the COM Port related to your connected GNSS device. (*it may differ from COM7 as shown in pictures*)
