TCP Sockets 
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.  
TCP Server Settings 
If  your  PES1A/PESV1A  is  configured  as  a  TCP  server,  other 
network devices can initiate a TCP connection with the serial device 
connected to the PES1A/PESV1A serial port. (This is also referred 
to as reverse telnet.) Network devices initiating connections must be 
configured with the IP address of the PES1A/PESV1A 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. 
Figure 13.  TCP Server Settings 
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.) 
TCP Client Settings 
If  your  PES1A/PESV1A  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.
