IE-CS(T)-2TX-xRS232/485 Web Console Configuration
5-19
Command port
Setting Factory Default Necessity
1 to 65535 966 Optional
The “Command port” is a listening TCP port that received IP-Serial Lib commands from the host. In order to
prevent a TCP port conflict with other applications, the user can set the Command port to another port as
needed. IP-Serial Lib will automatically check the Command Port on the IE-CS(T)-2TX-xRS232/485 so that
users do not need to configure the program.
TCP Client Mode
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: The IE-CS(T)-2TX-xRS232/485 automatically closes the TCP connection if there is no TCP activity
during this given time.
Inactivity time
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: The IE-CS(T)-2TX-xRS232/485 automatically closes the TCP connection if there is no serial data
activity during the given time.
This parameter defines the maintenance status as Closed or Listen for the TCP connection. The connection is
closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.
If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close request is
received. Although Inactivity time is disabled, the IE-CS(T)-2TX-xRS232/485 will check the connection status
between the IE-CS(T)-2TX-xRS232/485 and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, the IE-CS(T)-2TX-xRS232/485 assumes that the connection was
