Please follow the following steps to enable Virtual COM application in TCP Client Link
Mode
.
Figure 5.12
Virtual COM Application in TCP Client Link Mode
Follow step in
Paragraph 5.1.2 above
to configure SW550XC in TCP Client Link
Mode properly
.
Click on the drop
-
down list of the Application option under TCP Client section and switch to
“
Virtual COM
”
to enabled Virtual COM application in SW550XC
.
Scroll down to the bottom of the page and click on
“
Save & Apply
”
button to save the changes
.
Configure Virtual COM in the Operating System on the remote host computer
.
For Windows, please refer
to Chapter 6 below for the related instruction
.
Please remember the Destination Port
number configured
on this page in order to enter this information in Serial
/

5.2.4
TCP Client Application: Enable RFC 2217 through Virtual COM
The underlying protocol of Virtual COM is based on RFC 2217, which is the Telnet COM Control Option
.
Therefore,
it is possible to use RFC 2217 with SW550XC in the TCP Client mode
.
Note that the RFC 2217 allows a client, which
is SW550XC in this case, to initiates a Telnet session to a remote host computer to communicate with serial device
or serial
(
COM
)
program on the remote host computer
.
To do so, please refer to
Paragraph 5.2.3 above
to enable
Virtual COM so that SW550XC becomes aware of the command names and codes defined in RFC 2217
.
Note that
there is no need to configure Virtual COM on the Operation System
of the remote host computer because Virtual
COM ports would not be used
.
5.2.5
TCP Client Application: Configure SW550XC as a Pair Connection Master
A Pair Connection application is useful when pairing up two serial devices over the Ethernet or when it is impossible
to install Virtual COM
in the serial devices
.
However, the pair connection application does require two SW550XCs
to work in pair
.
One would be the Pair Connection Master and the other would be the Pair Connection Slave
.
