TCP Port number

Figure 7.5:

The TCP port number represents the source port number in TCP connec-

tions, and is the number used to identify the channel for remote initiating

connections. Range: 1-65535.

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

services, they need to define the TCP port to carry a long-term conversa-

tion.

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 Tel-

net connections. There are also custom sockets that users and developers

define for their specific needs. The default TCP port of EDG-4508+U/

4516+U is 5200. Opening a TCP session to port 5200 will form a raw

TCP/IP connection to the serial port.

Only configure the authorized IP

Figure 7.6:

This option is enabled in order to protect all configuration settings from

being changed inadvertently.

Note

1: If the serial port is in use, the socket

connection will be refused.

2: Timing between serial signals (such as DSR,

RTS, and DCD) is not preserved, and the state

of such signals is not readable.
