3.3.18. 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 controls pins of RS-232. However, the TCP Server is limited to a
maximum of four connections. If there are than four serial devices and does not use flow control pins with RS-232 or
RS-485, it is possible to setup pair connection in UDP mode (section
). After multi-connection is enabled in the
WebUI, refer to the following table to setup Pair Connection as in Figure 3.33.
