Server Properties Configuration

Flow Control

The Flow Control setting must match the requirements of the serial device connected.

Note:

Select None when setting the port as RS-485 or 4-wire RS-422.

TCP/UDP Protocol

Select TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) protocol. If the application does not require a UDP connection, select TCP. TCP guarantees reliable communication with error checking whereas UDP provides faster transmission.

UDP Mode

When UDP mode is chosen the Serial timeout, TCP alive timeout, Connection mode, Connection at, Max connection and Remote IP address fields are replaced with the following four fields: Destination IP address range, Port number and Source IP address range. In this mode the server can be configured to broadcast data to and receive data from multiple IP addresses. Four IP address range fields are provided.
