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 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.
Figure 9. 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 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.
