Property	Description
Name	Any name under which this database server appears in the connection project. Choose a name that is unique to you during connection project planning.

Port	Selection of the port for the database connection. The port can be changed if necessary.
Data source	Name of the database to be used.
User	User name for logging on to the PostgreSQL server.
Password	Password for logging on to the PostgreSQL server.

Property	Description

SSL Password	Password to access the private key of the client certificate, which is sent to the server during the SSL handshake.
Root Certificate	Select a root certificate (CA) from the drop-down list, which the OPC Router sends along with the data.
