4.2.10 TCP Server Application: Multi-Point TCP Pair Connections

The difference between Multi-Point TCP Pair Connection and Multi-Point UDP Pair Connection

is that the TCP implementation would also exchange flow control pins for RS-232. However,

the TCP Server is limited to a maximum of four connections. If there are four serial devices and

they don’t use flow control pins with RS-232 or RS-485, it is possible to setup pair connection

in UDP mode, Sec. 4.2.8. After multi-connection is enabled in the WebUI, refer to the following

table to setup Pair Connection as in Fig. 4. 18.
