The user interface, called the Client Interface, is used for all aspects of user interaction including setup of the information needed to collect data. For example, defining all of the equipment, creating users, resetting password, etc. The Client is also used to run charts and reports. The Client is installed by a per windows user basis.
Another task the Client performs is to configure and manually control the DataXchange Windows service. For this task the Client must be installed on a computer that can access the computer with the Windows service installed via a local network.
The default communication protocol between the Client and the Service is HTTP over TCP port 80. You may need to configure your firewall to allow this connection.
