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,
. After multi-connection is enabled in the WebUI, refer to the following
table to setup Pair Connection as in Fig. 4. 18.
