TCP Client in Virtual COM Mode
SW5001 can be configured to be TCP Client mode (PC as a server) to establish a TCP connection to an
application server on PC, or the Remote Control Host. Once the connection is established, PC or Remote
Control Host can exchange data with several serial devices at the same time through SW5001.
Configure

to
be
TCP
client
User can configure SW5001 to be as TCP Client for example, from
Fig. 7
. PC, as a server, has IP address
10.0.0.100 and listening on port 1000. Each SW5001, connected with serial device, configured as TCP
client mode with destination IP address 10.0.0.100 and the destination port 1000, and the IP filter is
disabled (by default).

4.2.2. Tunneling Mode
Tunneling Mode is used for multiple serial devices to “talk” among one another through SW5001’s through
wireless LAN or wired Ethernet. This mode is particularly useful when two or more serial devices are far
away. This mode can be used to extend the normal serial communication distance of 15 m to 100 m or
longer.
One SW5001 can be configured to be the TCP Server Mode with serial device connected and also another
SW5001 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, User can
implement SW5001 tunneling mode for Master /Slave mode PLCs or between other serial devices.
