away. This mode can be used to extend the normal RS-232 serial communication distance of 15 m to 100 m
or longer as shown in Fig. 8.
One EW5302 can be configured to be the TCP Server Mode with serial device connected and also another
EW5302 is configured as TCP client with serial device connected. After the connection is established, both
serial devices can exchange data to each other transparently. For example, users can implement EW5302
tunneling mode for Master /Slave mode PLCs or between other serial devices.

Configuring EW5302 to Tunneling Mode
Using one of two configuration methods (Web-based or Windows-based
SerialManager
utility), users can
configure EW5302 to TCP Server mode with a desired IP address and port, and with other EW5302 is
configured as TCP Clients mode with Server IP and port as destination IP and port respectively as shown
as an example in Fig. 9.
Note: TCP client has to assign the destination IP and the destination port corresponding to TCP
server’s IP and listening port (example: TCP 4660 port).
