SW5501 – SW5502
Wireless Serial Server
User Manual
Link modes and
Applications

Destination 2 : You can enable second remote destination for TCP connection if necessary by checking
on the Enable box in this option . Two different TCP servers can be set for redundancy .

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 .

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 .

Response Behavior : This option specifies how SW550X 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 4.5.2 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 “ Save &
Apply ” button to save all the changes that you have made .
5.1.3
Link Mode: Configure SW550X 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 . SW550X also supports connectionless UDP
protocol compared to the connection - oriented TCP protocol . The SW550X 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 SW550X 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 SW550X . Two remote host computers, which are on the same Ethernet network as SW550X, can
both send UDP datagram or messages to the serial display device through SW550X .
