OpenEdge makes use of the ADO/ODBC connection. So you must install the ODBC driver (64 bits) before you can connect to the database

By default, OpenEdge uses iso instead of UTF8 but can be changed on the setup of OpenEdge. As this is an ado connection, you must set the required datatype mapping as ODBC doesn't report field type names.
