Before starting Control Expert Topology Manager (TM) on the client side, please follow these steps:

1. Close TM on the server side.
2. Open the Server Configuration.
3. In the Listening Connections tab, update the Listening IP address:
   • Either select the Ethernet card used to communicate with the client PC,
   • Or enter 0.0.0.0 to listen on all Ethernet interfaces.

4- Apply the changes and close the configuration tool.

5- On the client side, open TM and go to User Preferences.

6- In the Networks and Servers tab, update the Control Expert Server Address with the correct IP and port:

• For example: IP = 192.168.189.1, Port = 19950.

7- Close and relaunch TM on the client side.

You should now be able to connect to the server successfully.
