The server symbol "listens" for a connection on a particular socket, and a client
symbol is capable of connecting or disconnecting a socket. A socket is comprised of
an IP Address and a Port Number. The IP Address is specified in the IP Table on the
IP ID that the symbol is on. The Port number is specified in the symbol. For
example, if the server symbol is dropped on IP ID 15, and the IP Table entry for IP
ID 15 is 192.168.1.1, the server will listen for a connection on a 192.168.1.1 on the
port number specified in the symbol.
In typical TCP/IP Terminology, a client connects to a server. In this case, the server
symbol can handle only one connection to it. Since the sockets are generic TCP/IP,
the client can connect to any server (Crestron's TCP/IP Server symbol or any non-
Crestron server) and the server can accept a connection from any client (Crestron's
TCP/IP Client symbol or any non-Crestron client).

TCP/IP Server and TCP/IP Client Symbols

The diagrams below and on the next page show the TCP/IP Server and the TCP/IP
Client symbols in SIMPL Windows. The table that follows each diagram lists the
inputs, outputs, and parameters, respectively, and their functional descriptions.
NOTE: TCP/IP Server and the TCP/IP Client symbols are available for the
CNXENT+ card only and cannot be used with the standard CNXENET card.
NOTE: All digital signals listed in the following tables can be high (logic level of
1), low (logic level of 0), and also have rising edge (when it goes from low to high)
and falling edge (from high to low) transitions. Depending upon how the symbol was
created, symbol inputs may work at the logic levels, some may work on transitions.
