Web services use the HTTP base port, which by default is set to 9400. You can change the value of the base port in the Configuration window, if required, after installation. Navigate to ...Web Services Interface > Communications > HTTP, change the value of Port (On Server Restart), and restart the TDV Server.

You can test the port connection (even if from the local Studio machine) by right-clicking either the admin node or the util node in the resource tree and selecting Test Service.
