You can use the WITS Outstation Form to configure network connections between Geo SCADA Expert and a WITS Field Device. For each connection, you need to specify the number of the TCP/IP port on which the Field Device (outbound) or Geo SCADA Expert (inbound) is 'listening'.
The settings at the top of the Form are for the outbound connection (Geo SCADA Expert to Field Device), and include a Port. In this Port field, you need to specify the number of the TCP/IP port on which the Field Device is 'listening' for connections from Geo SCADA Expert. There are two Port fields for Dual Networks: one for each network.
Further down the Form, there is a Port field for each Inbound Connection. For the inbound connections, you need to specify the number of the TCP/IP port on which Geo SCADA Expert is listening for connections from the Field Device. (The Listen Port is defined in the Channel configuration, see Configure a Channel's Network Connection Properties).
If the Geo SCADA Expert server or WITS Field Device are behind a router, you may need to specify a Port number on the router. The router will then need to be configured to forward the connection to the Field Device/Geo SCADA Expert server.
