If you have been upgraded to SummitCRS version 8 chances are you already have Terminal as it is part of the typical upgrade process. Look in your C:/Summit/Terminal directory to locate the application. If you do not have the application contact SummitCRS Support to have one of our technicians set up the applications for you.
If you have the application but it is not configured simply open Terminal and enter the IP address and port for your Summit Server. Checking the Automatically connect box will have Terminal automatically connect to the database each time the application is started.
