WITS allows for Field Devices to connect to a Master Station via a dial-up network, where the Field Device makes a telephone call to initiate a network connection.
If your network architecture means your Field Device needs to use a telephone call to initiate a network connection to Geo SCADA Expert, you will need to specify the Telephone Number. This is a setting in the Inbound Connections section of the WITS Outstation Form's Network tab.
For each Inbound Connection that uses the dial up network, enter the network connection details. These , include the Telephone Number for connecting to the network containing your Geo SCADA Expert server(s).
