3.2.4.1 TCP(UDP) Port number

The TCP(UDP) port number represents the source port number , and

the number is used to identify the channel for remote initiating

connections. Range: 1024-65533.

If an unknown caller wants to connect to the system and asks for some

services, they need to define the TCP(UDP) port to carry a long-term

conversation.

Each node on a TCP/IP network has an IP address, and each IP

address can allow connections on one or more TCP port. The well

known TCP port are those that have been defined; for example, port 23

is used for Telnet connections. There are also custom sockets that

users and developers define for their specific needs. The default TCP

(UDP) port of ADAM-4577 is 5200. The example initial 5200 is System

Port, and 5201 is Data Port. But users can adjust them by one's

preference or application.

Note1: Timing between serial signals (such as DSR, RTS,

and DCD) is not preserved, and the state of such

signals is not readable.
