5)
Destination IP 2
:
Please specify the preferred Destination IP address of the second TCP Server
program on the remote host in this field
.
This should match the IP settings of the second TCP
Server program
.
6)
Destination Port 2
:
Please specify the preferred Port
number of the second TCP Server program
on the remote host in this field
.
Once again, this should match the IP setting of the second TCP
Server program
.
7)
Response Behavior
:
This option specifies how SW550XC will proceed or behave when it receives
request from remote connected hosts
.
The description of each option is the same as described in
previous subsection
(
Section 5.1.1 above
).
For other Serial Settings on the same configuration page please go to
Section
and
for Advanced
Settings please go to
4.5.3 above
.
After finish configuring the Link Mode, please scroll down to the bottom of the page and click on
“

5.1.3
Link Mode: Configure SW550XC in UDP
Since User Datagram Protocol
(
UDP
)
is
a faster transport protocol than TCP but it is a connectionless transport
protocol, it does not guarantee the delivery of network datagram
.
SW550XC also supports connectionless UDP
protocol compared to the connection
-
oriented TCP protocol
.
The SW550XC Series can be configured to transfer
data using unicast or multicast UDP from the serial device to one or multiple host computers
.
The data can be
transmitted between a serial device and a remote
host computer in both directions
.
There is no server or client concept on this protocol
.
All networked devices are called peers or nodes
.
Therefore,
you only need to specify the Local Port that SW550XC should listen to and specify the Destination IPs of the remote
UDP nodes
.
Figure below illustrates an example of UDP Link Mode in which a serial display device is connected on
a serial bus and SW550XC
.
Two remote host computers, which are on the same Ethernet network as SW550XC,
can both send UDP datagram or messages to the serial display device through SW550XC
.
