3.6 TCP Port (Socket) Number
All TCP connections are defined by an IP address and a port number. A port number
is an internal address that provides a TCP/IP interface between an application
software on a computer and a device on the network.
There are three default TCP port (socket) numbers assigned to the iServer:
1. Port 1000: Once a TCP connection is made to the iServer using port 1000, the
iServer will forward the connection to the serial device and it will take the
response from the serial device and send it out to the network.
2. Port 2000: Once a TCP connection is made to the iServer using port 2000 (or
any port number that is configured on the iServer), the iServer will forward the
connection to the serial device and it will take the response from the serial
device and send it out to the network.
3. Port 2002: This port is the iServer’s network console port for reading or
changing the iServer’s settings. This can be done using a Telnet application.
Example: C:\>Telnet 192.168.1.200 2002
