Select TCP Sockets to implement Direct IP Mode using TCP. When using 
TCP Sockets your converter can be configured as a TCP server or TCP 
client.  

If your ES1A is configured as a TCP server, other network devices 
can initiate a TCP connection with the serial device connected to the 
ES1A serial port. (This is also referred to as reverse telnet.) Network 
devices initiating connections must be configured with the IP 
address of the ES1A and the TCP port number associated with its 
serial port.  

After selecting TCP Sockets, click Apply to return to the Serial 
Port Configuration page. Select the TCP Server Settings as 
required by your application. 

  

For each option, the TCP port number is shown. You can also 
Enable TCP Keep Alive for each selection. (If Enable Keep Alive 
is selected the connections is maintained even if no data is being 
sent.) 

If your ES1A is configured as a TCP client it will automatically 
establish a bi-directional TCP connection between the serial device 
and a server or other networked device. Selecting Automatically 
establish TCP connections enables this feature and its 
configuration options become available.
