Server Properties Configuration

•Default – When this mode is selected and the server is updated, it will revert the server to its default configuration.

•RS-232– When this mode is selected and the server updated, the selected serial port will become an RS-232 serial port on the server.

•RS-422– When this mode is selected and the server updated, the selected serial port will become an RS-422 serial port on the server.

•RS-485H– When this mode is selected and the server updated, the selected serial port will become a two-wire, half-duplex RS-485 serial port on the server.

•RS-485F– When this mode is selected and the server updated, the selected serial port will become a four-wire, full-duplex RS-485 serial port on the server.

Connection At

When the Connection Mode field is set to Client or Client (no heartbeat), this field becomes active, allowing the Serial Server (acting as a client) to connect to the server either on Power up or on Data Arrival (first character arriving).

Max Connection

This field allows the user to configure the Serial Server to have up to eight TCP connections.

Remote IP Address

This is a security feature activated by entering the IP address of the desired client. The Serial Server will only communicate with the listed IP address and all other requests for connection will be filtered out. The Serial Server must be set up as a TCP or UDP Server to use this feature. The default setting is 255.255.255.255.

If Paired Mode is not being used, do not change this setting until the application has been tested and is communicating properly. Then activate the address filtering feature.
