The GCU software upon startup will look for available servers and try to connect with the following order:

Although, the GCU will try to bind its own default server on local machine.

When GCU finds another server in local network, it appears under menu File/Servers and can be used for datalink connection.

VPN Support

Datalink server (part of GCU Software) has the capability to establish connection through internet with another GCU.

Two or more GCU interfaces could be connected to one or more datalink modems. the connection requires static ip, thus VPN connection is recommended.

To request for online support for tuning or troubleshooting, contact us to receive.login and password to acces our network.

The connection through our network can be established via menu Help/VPN Support.

Mandala control

The server will accept any request beginning with /mandala. The request parameters are following ? char, and are optional. Several request parameters can be combined in one request and separated by the & sign.

Google Earth Visualization

Add the following link to Google Earth:
