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 SW550X in the TCP Client mode
.
Note that the RFC 2217 allows a client, which
is SW550X 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 SW550X 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 SW550X 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 SW550Xs
to
work in pair
.
One would be the Pair Connection Master and the other would be the Pair Connection Slave
.
Figure
below shows a configuration of
Pair Connection Master application in TCP Server Link Mode
.
Please follow the
following steps to enable Pair Connection application and set the SW550X as Master in TCP Server Link Mode
.
Figure 5.13
Pair Connection Master Application in TCP Server Link Mode
Follow steps in
Paragraph 5.1.1
to configure SW550X in TCP Server Link Mode properly
.
Click on the drop
-
down list of the Application option under TCP Server section and switch to
“
Pair
Connection Master
”
to enabled Pair Connection application in SW550X
.
Scroll down to the bottom of the page and click on
“
Save & Apply
”
button to save the changes
.
Please remember Pair Connection Master
’
s IP address
(
i
.
e
.
SW550X
’
s IP address on your desired network
interface
(
either Ethernet or Wi
-
Fi
))
and Local Port number here in order to enter these information in
another SW550X device with the Pair Connection Slave setting later
.
Proceed to the Paragraph below to configure a Pair Connection Slave to connect to this Master
