1 Appendix A Quick Start Guide
The skyStation and airborne microLink radios are shipped from the factory
with a default configuration that allows them to connect on power up right
out of the box.
This quick start guide illustrates the steps to get up and going with your
pixHawk flight controller without any manual configuration.
Note that the radios depend on a GPS 3D fix in order to connect. A GPS
signal repeater is typically required for indoor operation. Also note that
some firewalls, antivirus/antimalware, and network switches may block
communication on certain network ports. Unblocking TCP ports 42430 and
42431 may be necessary.
1.1 skyStation
• Connect the skyStation to the Power+Data port of the power over
ethernet (PoE) adapter. Connect your router to the Data Only port of
the PoE adapter.

1.2 microLink
• Connect the PixHawk2 TELEM 1 port to the microLink USER port
(top connector).
• Connect the microFYX GPS to the microLink CNTL radio port (bottom
connector).
Figure 1-1 Airborne microLink connections.
• Apply power to your pixHawk. The TELEM 1 port supplies power to
the microLink and to the microFYX.

1.3 skyLinkApp and Mission Planner
Open the skyLinkApp.exe, configure the COM Settings to TCP, enter the IP
address of the skyStation, and enter the default Control port 42431. When
the data arrives, skyLinkApp.exe will begin graphing the radio link statistics.
NOTE: If you are not able to connect to the skyStation it is likely your
firewall is blocking the broadcast on port 42431. Please setup your
firewall to allow skyLinkApp.exe broadcast access to port 42431.

If you encounter a message from Windows Defender Firewall when
launching skyLinkApp, select Private Networks and press “Allow
Access”.

to plan your mission and fly!
